ABSTRACT 8

In an era of ecological collapse, Australia, which has one of the world’s highest greenhouse gas emissions per capita (Climate Transparency 2018), needs to transition to an environmentally sustainable economy. The ‘Australian Dream’ of detached homeownership set the foundations of the country’s urban structure, suburban sprawl (Richardson 1995). Detached or semi-detached housing comprises 86% of Australia’s current housing stock, compared with just 16% of current building approvals for multidwelling structures of four or more storeys (UDIA 2018). In Victoria, the residential sector is responsible for almost 30% of total greenhouse gas emissions (SVDELWP 2019). Suburban Sprawl is energy inefficient, responsible for the destruction of agricultural land, habitat loss, increase in water run-off and damage of waterways, high infrastructure demand and car dependency with long commutes (Calthorpe 2017). It also has severe negative social and cultural impacts and affects cities’ economic vitality, no longer being a feasible way to build cities. This project is a case study investigation into how medium-density landscape-oriented urban developments can provide environmental, social and economic benefits, and how design plays a crucial role in assisting in the transition from Suburban Sprawl into a more sustainable city. Fitzroy Gasworks’ urban design framework evolution is analysed, and a proposal is made to illustrate the best outcome, balancing social, environmental and economic spheres.

This work investigates the negative impacts of Suburban Sprawl and explores how Melbourne can double its population without duplicating its footprint. It investigates the most suitable areas for densification and examines global and local precedents to generate the design of a particular case study, Fitzroy Gasworks urban renewal. It analyses the project’s publicised documents and establishes evaluation criteria based on a top-down (Development Plan Overlay 16), a bottomup (Protect Fitzroy North Resolutions) and a sustainability rating (Green Star Rating System) approach. Based on the new criteria, it proposes an alternative design that illustrates how a landscape-oriented urban development provides the best outcome balancing social, environmental and economic spheres. It also aims to highlight how design plays a crucial role in assisting in the transition from Suburban Sprawl into a more sustainable city.

Australia’s high greenhouse gas emissions (GHGs) are deeply related to its growth pattern and physical structure, as the typical Suburban Sprawl characterises its major cities. The ‘Australian Dream’ of detached homeownership set the foundations of the country’s urban structure (Richardson 1995). Detached or semi-detached housing comprises 86% of Australia’s current housing stock, compared with just 16% of current building approvals for multi-dwelling structures of four or more storeys (UDIA 2018). Suburban Sprawl is energy inefficient, responsible for the destruction of agricultural land, habitat loss, increase in water run-off and damage of waterways, high infrastructure demand and car dependency with long commutes (Calthorpe 2017). Since the late 1970s, different urban growth scenarios have been investigated as an alternative to Sprawl. The Smart Growth model is based on principles like mixed-use land uses with distributed employment clusters, walkable neighbourhoods with a variety of transportation choices and a range of housing opportunities, strengthening of existing and new community lifestyles and preservation of open space and farmland. In comparison to the Smart Growth model, Suburban Sprawl produces 330% more GHGs (Calthorpe 2017). In Victoria, 30% of the total GHGs are related to the residential sector (SVDELWP 2019).

While on one hand, Suburban Sprawl is destructive for the environment, it also has severe negative social and cultural impacts and affects cities’ economic vitality (Calthorpe 2017). Sprawl enhances social isolation, affecting our sense of community and connectedness.

12

Suburban Sprawl is the land of the private garden and creates sterile public environments. Long daily commutes for work and leisure waste a significant number of hours that could be better spent on social and cultural exchanges, affecting people’s well-being and mental health. In growing multi-cultural cities such as Melbourne, people with no local family depend on co-operative relationships to thrive, and sprawl does not have space for that.

In terms of economy, denser settlements can reduce 50% of annual household costs and government investments in public infrastructure and health care (Calthorpe 2017). Residential tasks’ distribution and development of collaborative relationships between neighbours also capitalise the household’s income. Homelessness in Melbourne has increased by 17% in the past two years, with a direct cause being booming housing price (Roberts 2020). The increase in homelessness not only points to the inaccessibility of housing stock but also a growing divergence in social classes. With the housing affordability crisis reaching its peak, alternatives need to be investigated.

One option for overcoming this complex challenge is to increase community-oriented living arrangements, which allows for numerous benefits, including physical and mental health improvements. Growing inwards preserves farmlands, natural reserves and reduces investments in transport and service infrastructure, reducing habitat loss, water run-off and damage of waterways. Multi-dwelling structures can reduce up to 50% of water and energy usage (NSWDP 2006), resulting in a reduction of 56% the GHGs, in comparison to single dwelling structures (COAG 2018). Car dependency affects human physical and mental health, destabilises ecological systems and generates significant annual expenses. The concentration of employment in residential areas, through mixed-use land-uses, allows for more walkable and car-free networks.

Within this scenario, this project aims to investigate which Melbourne areas would be most suitable for densification and to develop an in-depth design process for a key site. The main objective of this design process is to demonstrate how a medium-density landscapeoriented urban development provides the best outcome balancing social, environmental and economic spheres. It also aims to highlight how design plays a crucial role in assisting in the transition from Suburban Sprawl into a more sustainable city.

13

The Design Methodology employed for this project was based on eight points: 1.

Establish criteria to find the most suitable areas for densification

2. Develop a data-driven planning process 3. Choose a key prototype site 4. Do a site analysis 5. Review its urban design framework 6. Establish a critical position 7. Develop design iterations 8. Detail key locations

Suitable locations for densification were investigated based on three criteria: infrastructure supply, land use, and demographics.

Through a data-driven planning process, the criteria were overlapped, reaching a three-phase framework for densification areas. As culture was identified as a substantial impediment for densification, these three implementation phases were generated through a ranking based on high-rise residents profile. Among all appropriate areas highlighted in Phase One, one site with the potential to become a role model higherdensity urban development was chosen: Fitzroy Gasworks. This site is an urban renewal of a former Gasworks led by Development Victoria, that is intended to develop 1100 dwellings with 20% of affordable housing, a senior secondary school, a sports centre and integrated with community infrastructure (DV 2019).

This project involved a site analysis, investigating its historical and current situation. The site is a former brownfield and is going through an extensive soil remediation process, which creates an almost blank canvas for the design intervention. As a 4Ha publicly-owned space, it has the potential to achieve more significant outcomes than smaller plots managed by traditional developers. Its proximity to the CBD and availability of transport infrastructure makes it a connected part of the city, not only benefiting from its context but with the scope to supplement it. Close to several commercial stripes- Smith Street, Brunswick Street, Nicholson Street, Johnson Street - besides the remarkable cultural scene existing in Fitzroy, the site feels like an island in a bustling, vibrant neighbourhood. The Fitzroy Gasworks has social and cultural significance and also has environmental potential, providing many opportunities for a successful prototype with social, ecological and economic benefits.

15

The development’s timeline was reviewed, investigating various documents. With its first Urban Realm Framework released in 2008, two rounds of community engagement in 2017, and another two Masterplans issued to date; the project is set for another round of community participation in early 2020 (which did not occur yet due to the pandemic) and construction works to begin in 2021 (DV 2019).

Local and global parameters for densification were investigated, with several precedents of cities with high quality of life showing much higher densities than Melbourne’s typical 12 dwellings/hectare, but less than the 367 dwellings/hectare proposed by Development Victoria. A thorough analysis of the Development Plan Overlay that enabled the site’s rezoning (DPO16), parallel to the community group (Protect Fitzroy North) resolutions was made. The Green Star Rating System criteria for communities and performance was examined and overlapped with all previously mentioned points, which culminated in the development of the Design Criteria.

The Design Criteria established the parameters to evaluate the Design Approach presented in this report, which aims to develop a landscape-oriented urban development. The major points are:

16

•

Integrated water system

•

Investigation of the maximum building envelope without affecting the quality of open space

•

Allocation of communal outdoor space to all housing

•

Biophilic architecture

•

Central spine across the block with the main gathering space at its core

•

Heritage plaza

•

Active frontages to main streets, with mixed-use precinct

•

Car flow directed underground and pedestrian/cyclist priority on the ground level

•

High tree canopy

•

Vegetation in abundance

Taking into consideration all points identified in the Design Approach, a series of massing studies was sketched. For the initial design stage, it was crucial to investigate the maximum building envelope without affecting the quality of open space while allocating communal outdoor space to all housing. 3D modelling and sun studies were used for that investigation and produced three distinct design iterations. The third iteration had the best performance in allocating the maximum amount of housing without negatively affecting the open spaces, public or private, within the precinct. This iteration was selected for the next design stage, the detail design. This stage involved the development of a site plan, detailing three specific areas: the central spine with a wetland system (for its ecological improvement), a communal residential outdoor space (fostering the cultural transition from the private garden to the shared garden) and a heritage plaza (highlighting the mixed-use character of the precinct and new economic possibilities. When all the points from the Design Approach were developed in the design, a walk through the 3D model was performed. This result was presented in the final video submitted for this project’s completion.

SCENARIO This work is framed by the analytical perspective of a built environment designer in the context of a climate emergency set in Melbourne, Australia. The UN Intergovernmental Panel on Climate Change warns us that to avoid catastrophe, human societies have 11 years to wholly transform the way we use energy and land, making changes on a scale for which “there is no documented historic precedent” (UN 2019). Australia has seen its land go through increasing ecological instabilities which is set to progress with an extraction economy (a resource-based economy, dependent on harvesting or extracting natural resources for sale or trade), continuous population growth and negative land management strategies (Hinton 2018). The ‘Australian Dream’ of detached homeownership set the foundations of the country’s urban structure, suburban sprawl (Richardson 1995).

The Victorian government forecasts a 70% population increase in Melbourne in the next 30 years (SVDELWP 2019). With a current total area of 10000km2, the city would need to reach 17000km2 in order to allocate its traditional housing structures. Figure 2 shows Melbourne’s current fringe conditions. The city, which has been expanding its Urban Growth Boundary successively, borders Green Wedges, Conservation and Rural Conservations Areas. These areas contain a mix of agriculture and low-density activities, national parks, other parks, reserves, and closed protected water catchments. In order for Melbourne to continue growing horizontally, food production areas need to become housing.

Although each city has a specific development history, underpinned by cultural, political and economic factors, it is vital to examine each city’s situation in the global context, as it creates parameters of analysis.

It is widely known that Australian cities present the most extensive and least dense settlements in the world. This is due to their vast availability of land and expansion over periods when automobiles already existed (Richardson 1995), allowing the city boundaries to extend. Melbourne, with a population of 5 million in 2020, has a population density of 500 people/km2. Although the densest city in Australia (“How is density changing in Australian cities?” 2020) - followed by Sydney (407 people/km2), Adelaide (400 people/km2), Perth (310 people/km2) and Brisbane (145 people/km2) - Melbourne is among the least densely populated cities in the world.

Figure X presents the population density in some of the world’s big cities. While the densest cities can reach up to 44000 people/km2 (Dhaka), old European centres present an average of 15000 people/ km2 (Paris: 21000 people/km2, London: 15000 people/km2, Berlin:

GLOBAL SCENARIO

3800/km2, Copenhagen: 6800/km2). Latin-American big cities are also densely populated ranging from 6300 people/km2 (Santiago) to 16600 people/km2 (Bogota). The United States presents a variety of density patterns, from the global metropolis of New York with 10200 people/km2 to sprawled cities such as Los Angeles with only 2400 people/km2.

It would be inaccurate to establish an ideal population density number for a specific city since every case is particular to its own parameters. Even the population density number in itself is an approximation, given the different urban fabrics that constitute the cities.

Australian urban boundaries usually comprise a series of natural parks, besides having extremely different structures between the CBD and its suburbs. All of those factors are suppressed when a single population density number is used to define a much more complex system.

Nevertheless, these numbers will be a reference for further evaluation.

Within this scenario, Australian cities stand out with very low population densities.

25

With only 0.33% of the world’s population, Australia is responsible for 2% of the world’s total greenhouse gas emissions (GHG) - 5% if you consider exports (Climate Transparency 2018). China, with 19% of the population, is responsible for 26% of GHG and the United States, with its 4.25% of world’s population emits 15% of GHG (Climate Transparency 2018). The ratios of tonnes of emission per capita for each are Australia 1: 6; China 1: 1.37 and USA 1: 3.52, which shows that the Australian population emits almost 5x more per capita than the Chinese.

As a wealthy developed country with such a small population, Australia should be leading the carbon-zero footprint campaign, but instead sits 11th in the global emissions per capita ranking, next to countries like Kuwait, Qatar and the United Arab Emirates, with their oil-based economies. Australia’s high emissions are closely related to its growth pattern and physical structure, characterised by suburban Sprawl. Figure X shows the breakdown of GHG emissions in Victoria per sector and how they relate to the residential area.

‘Emissions are first and foremost a problem created by the affluent industrialized nations. The USA and Australia have greenhouse gas emissions averaging 22 and 28 tonnes per head respectively, compared to less than 1 tonne for many developing nations, including China. The sustainable level of emissions has been estimated to be about 3.5 tonnes for every person on planet Earth.’1 1 Lenzen, M., ‘Individual responsibility and climate change’, Environmental Justice Conference, The University of Melbourne, October 1997.

SUBURBAN SPRAWL AND THE ENVIRONMENT In Victoria, 30% of GHG emissions are related to the residential sector, which is the most significant amount emitted by one sector (Fig. 9). Suburban Sprawl is energy inefficient, responsible for the destruction of agricultural land, habitat loss, increase in water run-off and damage of waterways, high infrastructure demand and car dependency with long commutes (Davidson 1993). On the other hand, the Smart Growth model is a model of urban growth based in principles like mixed-use land uses with distributed employment clusters, walkable neighbourhoods with a variety of transportation choices and a range of housing opportunities, community-oriented lifestyle and preservation of open space and farmland. In comparison to the Smart Growth model, Suburban Sprawl produces 330% more GHG emissions (Calthorpe 2017).

Peter Calthorpe (2017), a North American urban planner, analysed both Suburban Sprawl and Smart Growth, in his research about Californiaâ&#x20AC;&#x2122;s future urban development. The data (fig. 8) shows a 69% reduction in land consumed, a 70% reduction in greenhouse gas emissions, a 42% reduction in vehicle miles travelled, a $2.8bi saved in health care (related to respiratory diseases) and a 52% reduction in annual household costs for the Smart Growth scenario.

SUBURBAN SPRAWL AND THE COMMUNITY While on one hand, Suburban Sprawl is destructive for the environment, it also has severe negative social and cultural impacts, especially on a growing metropolis. As the city expands and people live further and further apart, it becomes increasingly hard to achieve community-oriented neighbourhoods. Sprawl enhances social isolation, affecting our sense of community and connectedness (Calthorpe 2017).

Suburban Sprawl is the land of the private garden and creates sterile public environments. Long daily commutes for work and leisure waste a significant number of hours that could be better spent on social and cultural exchanges, affecting people’s well-being and mental health (Gwilliam 1998). Furthermore, Melbourne has a multi-cultural character with more than 50% of its residents from a different cultural background and over 50% born overseas (ABS 2018). This means that many households have no local family. In this scenario, many citizens depend on the support from their neighbours and local communities to thrive, and sprawl does not support that.

In terms of economy, denser settlements can reduce 50% of annual household costs and of government investments in public infrastructure and health care (Calthorpe 2017). Residential tasks’ distribution and development of collaborative relationships between neighbours also capitalise household’s income. Homelessness in Melbourne has increased by 17% in the past two years, which not only points to the inaccessibility of housing stock but also a growing divergence in social classes. With the housing affordability crisis reaching its peak, alternatives need to be investigated.

“Because so much depends on how we shape our cities: not just environmental impacts, but our social well-being, our economic vitality, our sense of community and connectedness.”

(Calthorpe 2017)

SOCIAL ISOLATION

One option for overcoming this complex challenge is to increase community-oriented living arrangements, which provides numerous benefits, including physical and mental health improvements. Growing inwards preserves farmlands, natural reserves and reduce investments in transport and service infrastructure, reducing habitat loss, water runoff and damage of waterways. Multi-dwelling structures can reduce up to 50% of water and energy usage (NSWDP 2006), resulting in a reduction of 56% GHGs, in comparison to single dwelling structures (COAG 2018). The car dependency affects human physical and mental health, destabilises ecological systems and generates large annual expenses. The concentration of employment in residential areas, through mixed-use land-uses, allows for more walkable and car-free networks.

The creation of communal spaces allows for a more inclusive and democratic city because they support residents to collaborate and distribute household costs and tasks (Holtzman 2011). With more time and money, people have more opportunities for recreational activities, which generates physical and mental health improvements, helping to overcome issues such as loneliness and isolation. The advantages achieved with co-operative relationships extends beyond a single demographic group. From young households, families with children to older houses - especially one person households - sharing brings many advantages, and communal spaces allow for more intergenerational exchange, which fosters mutual empathy and creates more selfless human beings (Alexander 1965).

CONNECTEDNESS

DENSITY AND KNOWLEDGE ECONOMY Jose Antonio Carlos, a Brazilian economist, punctuates the importance of associating design and economy. According to Carlos, the weight of the four primary inputs responsible for the formation of wealth (land, labour, capital and knowledge) have changed through time. Figure X shows their participation in the economy according to the different economic eras. Knowledge, in particular, has three very peculiar characteristics that distinguish it from other economic inputs.

The recognition of those is essential for cities that want to extract all their transformative potential (Carlos 2018).

1. The first one refers to immateriality. Unlike other factors, knowledge has no physical dimension. We cannot see it, weigh it, or subject it to any other classic measurement process used for material goods.

2. The second fundamental knowledge trait is that it comes from people. Having ideas, designing new services, seeing opportunities are unique attributes of the human being.

3. The third specific characteristic of knowledge is that it grows with sharing. Unlike any material good, in which the removal of a portion reduces its size and/or value, exchanging ideas and sharing experiences increases the knowledge of the involved parties.

Through time, knowledge transitioned from a mere supporting role to becoming the protagonist in the wealth creation process (Nonaka 2008). That is why cities are having to reinvent themselves to transform individual tacit knowledge into social innovation. Distinct cities present different economic structures. Harvard Growth Lab’s recently released its Atlas of Economic Complexity, a tool to understand the economic dynamics of countries worldwide. Australia ranks 93 in its economic complexity, close to Senegal and Pakistan (HAEC 2017). Australia’s high GHGs are also deeply related to its economic structure, still highly dependent on the extraction of natural resources.

Until the economic framework starts shifting to more innovative and sustainable industries, the country will face a significant challenge into achieving any carbon-neutral goal. This work focuses on design’s contribution to this passage. In opposition to the construction of excessively segregated environments centred on private living arrangements, this work advocates for the creation of spaces that encourage the involvement of people. People congregate in order to work together; work is at the core of social life (Low 2005). Settings that foster exchange of experiences, inclusion and practice of transdisciplinary activities are essential in the pathway towards a sustainable economy.

Design is responsible for leading a densification process that connects the creators of knowledge, the people.

‘AUSTRALIAN DREAM’ Figure X shows the comparison of Greater Melbourne’s housing product mix to what Peter Calthorpe (2017) establishes would characterise the Smart Growth scenario. Melbourne shows 84% of its housing mix composed of detached, semi-detached or attached houses, with only 16% of multi-residential houses (UDIA .) .

While several places in the world have developed distinct forms of residential models with communal open space, Australia has very few precedents and has just recently begun to show different development structures. Some examples will be showcased in the next chapter. New development structures are questioned by a significant portion of the population, familiar with the formula of the freestanding house and the private garden. The foundations of this cultural perception date from the early European settlement periods.

Australia’s modern settlement pattern began urban and quickly shifted to suburban, with the Australian Dream (ownership of a detached house on a “quarter-acre block” in the suburbs) becoming an entrenched cultural tradition (Richardson, 1995). According to Davidson (1993), the suburbs became the “compromise between the necessity of the city and the idealised dream of the country”, in which the possession of a detached house and private garden is a symbol of personal success and security. With high rates of population growth around the 1950s and the widespread use of the automobile alongside the lack of policy on land occupancy, the city vastly expanded its boundaries, resulting in massive suburban sprawl. When the authorities began to acknowledge the downfalls of an infinite sprawling urban form, a series of planning documents were issued, attempting to give the growing metropolis a more compact and sustainable shape. Melbourne 2030, published in 2002, was the first greater Melbourne planning document that sought to shift the growth behaviours into more consolidated areas, the activity centres (SVDI 2002). The document aims to restrict the city’s 34

spread by densifying specific areas composed of housing, employment, infrastructure and retail, reducing the necessity for long daily commutes.

This report has received critique from planning specialists, who state that it presents an incorrect analysis of the forecast demographic changes, establishing guidelines that will not be embraced by the population - who are still attached to the suburban city model. According to Birrell (2005), the document fails to propose solid policies and strategic plans, focusing on a series of broad generic views. The implementation of an Urban Growth Boundary (UGB) is highly criticised by the fact that it does not restrain any extension - since it is flexible – but it created an escalating price in greenfield land, which therefore entailed an affordability crisis that is now seeing its peak (Birrell 2005).

In 2008, Melbourne 2030 received an update, Melbourne @ 5 million. With a similar philosophy, the updated version begins to define the central activity districts, establishing 6 CBD-like cores alongside employment corridors (SVDPCD 2008). Subsequent planning documents presented an increasing level of detail in their policy, with the use of maps and diagrams bringing the broad and extensive guidelines to a more tangible and realistic plane. Plan Melbourne 2014 also supports a polycentric city, but defines only metropolitan activity centres, not the range of varied and non-simplified scales as previously defined.

It establishes VICSMART, a policy to simplify approval processes, by declaring low-impact planning permits and mentions greenhouse gas emissions for the first time. Plan Melbourne 2017-2050 follows the same principles from the previous documents and presents the first acknowledgement of the aboriginal custodianship of the land, talking closely about storytelling and heritage, demonstrating the reach of more sensitive planning strategies. It presents possibly one of the most important tools when it comes to urban planning, which is the notion of a framework. The first Implementation Plan defines short, medium and long-term timeframes for each objective and a strategy to achieve it (Minister for Planning 2017).

In 1986 Bunker highlighted the “paramount concerns requiring urgent measures to bring about change” by stating the environmental costs of Suburban Sprawl including increased GHGs emissions. Thirtyfour years later the city has not altered its values, with mainly planning specialists acknowledging the need for modification. A metropolis with a high index of liveability and sustainability needs to be polycentric, providing efficient transport corridors along with neighbourhoods that offer service and community infrastructure. Australian suburbs, which “promote mindless conformity, isolation and deprivation” (Richardson, 1995), need a strategic framework that helps to shift the current mindset attached to the Australian’ Dreamscape’ to welcoming alternative living arrangements.

HOUSING [AFFORDABILITY] CRISIS As the population grows and housing stock does not supply demand, land and house prices escalate. Greenfield developments sum up to 22000 new lots annually, around 35% of the new housing stock, with only 2% of those being apartment units. Among the new apartment blocks, 50% of the market is dependent on investors, with the few apartment buyers usually characterising the stage before being able to buy a detached house (UDIA 2019). From Victoriaâ&#x20AC;&#x2122;s 2018/2019 total building approvals, 62% are houses, 18.8% semi-detached or townhouses and only around 20% are flats or apartments, of which 15.8% have four or more storeys (UDIA 2019). Infill redevelopments are a significant source of supplying the required housing stock. Although it can be a great strategy to densify locations that are already provided by infrastructure, without proper regulation, it can present an adverse outcome. Fig. 14 shows the phenomenon as it is mostly happening around Melbourneâ&#x20AC;&#x2122;s suburbs.

A profit-led real-estate market leads to properties being subdivided and occupied to extract the maximum value for the land, which means the suppression of any outdoor and social area. Although most new developments are low-rise - since it is the cultural default - developers seek permits for medium to high-rise. Even though a necessity to allow Melbourne to grow more sustainably, apartment buildings have not had enough regulations to guarantee a quality outcome. While meeting a need to supply increasing housing demands, especially from low-income social groups, these buildings have historically presented a sterile piece of engineering instead of a group of houses, which does not promote highrise as a good option.

The Victorian government recently introduced regulations for apartment design, with the “Better Apartments Design Standards” released in 2017 to “improve the internal design of new apartments and make them more liveable and sustainable” (SVDELWPc 2016) and the new “Better Apartments in Neighbourhoods” coming in 2020 to deliver improved relationships between new apartments and the amenity of existing neighbourhoods (SVDELWPb 2019) . Both planning tools will hopefully ensure an increasing quality in apartment design and its impact in the surroundings.

Homelessness in Melbourne has increased by 17% in the past two years, with a direct cause being booming housing price (Roberts 2020).

Melbourne currently has a high liveability index, largely due to its safe conditions, a consequence of a relatively equal social structure. The increase in homelessness not only points to the inaccessibility of housing stock but also a growing divergence in social classes. It is also known that there is an overall tendency of the real estate market to favour landlords and developers over the broader public, especially renters. This story has been seen in many places around the world, with increasing economic shortage leading to progressing insecurity and, finally, conflict.

Social inequality means that part of the population receives much less income than others. Sometimes the lack of income generates economic insufficiency to survive, and robbery becomes a solution. Fortunately, Melbourne still delivers a distinctively safe lifestyle. That will not be for long if the status quo does not change.

ALTERNATIVE HOUSING MODELS Parallel to the rise in homelessness and the housing affordability crisis, the city has seen an increase in alternative housing models, which offer an opportunity to remedy those issues. New developers such as Nightingale, Assemble and Property Collective aim to provide a more affordable, sustainable and community-oriented housing option.

Although an alternative, without government support, these initiatives struggle to deliver competitive solutions in a profit-led market. These new developments - while distinct from each other - have foundations in the community as a core of the housing structure and have been accepted by different demographic groups. While some specific groups are more open to these alternative models, a significant portion of society is still apprehensive of the change they provide.

Assemble Papers have been advocating for a change in housing practice by illustrating a series of case studies around the world. In one of these articles, Manuel Lutz (2019) highlights the qualities of housing co-operatives, which invert the profit-led market focus for a use-value, by pooling the small resources of many into a non-profit company. He states: “In the current crisis of housing affordability, co-operatives show potential to square the circle of affordability and quality, combining low cost with high-quality living”.

With many successful precedents around the world, mainly in European cities, co-operatives have established a housing alternative with an “inbuilt emphasis on democracy, equality and solidarity within a long-term, stable community” (Lutz 2019). Melbourne-based cases have appeared sparsely in the past fifteen years, becoming each time more consolidated, with its precursor being Murundaka Cohousing.

In another Assemble Papers article, the urban design critic Andy Fergus (2018) explains different types of co-operatives and how they operate. These are summarised in the next pages, with an example project illustrating each.

A housing proposal by Andy Fergus, Katherine Sunderman (associate director of MGS architects) and Alexis Kalagas (urban strategist and writer) was shortlisted in the City of Sydney’s Alternative Housing Ideas Challenge. Their project, the ‘The Third Way’, focused on the financial model and planning context associated with the design, using Zurich as a strong precedent. While in Australia 60-70% of people own their home, Zurich has never gone above 10%. In a talk given in MPavillion, Kalagas (2020) stated that Zurich’s entire system has been built around the need of renters and that 20% of the housing stock is composed of co-operatives. Sunderman declared that 92% of Melbourne’s renters want their own home, but over 50% of the younger generation will never have their own home.

As Australia’s housing culture is based on ownership, the rental market has never had specific controls to establish a secure and quality condition for renters, having instead privileged the landlord. The outcome is a society that sees renting as a stage in life until they can purchase a house. Apartments appear in more significant numbers to supply increasing demand, but 70% of them are rented, in comparison to 20% of houses. Apartment buildings reflect a more short-term, affordable opportunity than providing a long-term housing alternative.

Speaking at MPavillion about speculations on Melbourne’s future homes, Fiona Andrews (2020) (Senior Lecturer at Deakin University Health Department) states that over 40% of Melbourne’s apartment

residents are families with children even though their design does not support the lifestyle of young families. “Everything seems to be done for aesthetics rather than practicalities.”

She quotes an interviewed resident “I just want to be able to go outside for a cup of tea and put my toddler down so he can crawl around. I feel like in the interest of cost-saving, they have really missed an opportunity to capitalise on the natural environments that surround the building. So, to have a cement slab, and not invest in a communal garden or landscaping or anything that is sympathetic to the surrounding nature seems to be a massively lost opportunity.” In Andrews’ opinion, the solution to accommodate the growing population without doubling the cities’ footprint is to develop more family-friendly apartments.

In the same talk, Amanda Roberts (2020) says that Australia has an obsession with profiting from property, while in most of the rest of the world that’s not the case . She quotes an influential climate activist: “How dare we think we have the right to own more than one home ooperative movementand hasexploit the misery and isolation and fear that mortgage stress and housing stress creates for different families.” Roberts criticises the use of atives, popular support, have also benefited the neighbourhood character as a planning tool to disguise people’s ‘Not using and the financial in My Backyard’ (NIMBY) attitudes about design and development.

PRECEDENT INVESTIGATION Murundaka Cohousing is a great local example of the social, economic and ecological benefits provided by medium-density developments. The project was made possible in 2009 with support from the Common Equity Housing Limited (CEHL) and an injection of funds into the social housing sector. It is now a consolidated housing community with 20 households sharing common living, kitchen and garden space. Producing 100% of their electricity needs with solar panels, the community had a 50% reduction in their bills (MCC 2016).

Its block analysis provides some interesting insights in terms of spatial configuration and infill. Located in Heidelberg Heights, 15km from the CBD, most houses in the block are still detached, with generally 12 dwellings/Ha. A few plots have started being subdivided into more low-density units, with the suppression of all outdoor area. On the other hand, Murundaka Cohousing manages to increase the density more significantly while improving its green space.

Unfortunately, initiatives like Murundaka are still rare and require an engaged group of people to investigate alternatives and chase funding. Most market is led by the optimisation of the plots through traditional infill practices and a large housing demand ready to take whatâ&#x20AC;&#x2122;s available.

Several precedents of cities with a high quality of life show much higher densities than Melbourne. Research identifies 50 dwelling/hectare as the minimum for sustainable development.

Some design competitions have been launched by Australian state governments trying to address the densification challenge. In 2019 the Queensland government launched the competition ‘Density and Diversity Done Well’ to investigate what might be called the “missing middle”. The “missing middle” is a term that aims to explore the lack of housing typologies between the standard detached house and the high-rise. This competition sought proposals for new housing options for Queensland that meet contemporary community, urban and environmental challenges (QDDHPW 2019). New South Wales government’s ‘Missing Middle Design Competition’ invited professionals to showcase their visions for the future of medium density housing in NSW. Analysis of the winning designs showed alarming uniformity, with just slight formal changes in the facade and composition. Most proposals developed their design following the traditional fence boundary, finding a solution for one plot and replicating it in the entire block. It is clear how even the professional design field is struggling to foresee that a dwelling footprint can go beyond the standard lot edge, working with combined plots for a proposal that comprehends the block as a whole. Even if that characteristic was stated in the brief, it was not challenged by the competitors.

At the Future Homes MPavillion talk, the presenter Andrew Mackenzie (2020) discussed the inauguration of a Melbourne-based design competition called ‘Future Homes’, with a $500,000 prize. This announcement highlights the importance of addressing the density issue and reveals one of the design field’s most significant leaders on this issue.

Another Melbourne initiative underway is IBA Melbourne, inspired by the European movement Internationale Bauausstellung – or International Building Exhibition (IBA), initiated in the Mid-twentiethcentury in Germany. “IBA Melbourne is proposed as a city-wide, crossinstitutional project that aims to affect the transformation of housing provision in Melbourne through demonstration and engagement.

An initiative of four universities: Melbourne, Monash, RMIT and Swinburne, it involves architectural and planning professions, all levels of government, financial and philanthropic institutions, and industry.

The initiative is still under development and there are no in-depth details available for consultation.

Despite an unfavourable economic scenario due to the pandemic, these contemporary actions point to positive changes. It feels like the right moment in history to deconstruct some ingrained behaviours and pivot the future’s course.

6. Two blocks are amalgamated, allowing for a larger courtyard to form in the centre. This larger block encourages an intergenerational community to evolve, with flexible housing for diverse demographics.

7. Amalgamating corner sites allows for side access, and greater street engagement for smaller garden dwellings between existing houses.

8. Joining across the centre of the block creates a linear courtyard, connecting people as they pass by each others’ windows, and creating a new suburb connection.

9. As developments increase, adjacent blocks can begin to share even more. In this instance, this block uses its neighbours pool, while the large workshop space becomes a hub for the wider community.

DENSITY : An ECONESTING neighbourhood can increase density in a typical block by 3 or more times resulting in an additional 40 or more family/ user groups being housed in the same area as this typical neighbourhood block. At the same time, with small footprint living we can achieve 60- 70 % Open Space and with Planned Developments actually increase the overall tree canopy, creating a more pleasant micro-climate and offsetting the carbon footprint of the new buildings.

DIVERSITY : Econesting is highly sustainable and allows a large diversity of Types to accommodate Downsizers, Fly the Nesters, Home Office workers, Small Families and Inter-generational living - all promoting an active and inclusive Community. ECONESTS can be woven through the fabric of an existing suburb over time minimising large scale disruption and also allowing the option of keeping much of the existing housing stock which can be upgraded to minimum Energy Standards over time.

DONE WELL : With clear and logical Planning Controls the contentious issue of Infill housing could rather be sold as a way of improving the Environmental outcomes of a suburb at the same time as being a way Residents can maximise the value in their own backyard while improving their way of living. The small scale of ECONESTING allows Residents the option of developing for themselves which in turn makes it more economically feasible and promotes development with an Environmental and Social Conscience.

SIMPLIFYING WICKED PROBLEMS From the context’s analysis to a site specific design proposition, this work establishes two main goals: •

To develop an in-depth design process for a key site, demonstrating how a medium-density landscape-oriented urban development provides the best outcome balancing social, environmental and economic spheres.

•

To highlight how design plays a crucial role in assisting in the transition from Suburban Sprawl to a more sustainable city.

The strategy employed in this project, therefore, is based simultaneously in a traditional design process (from the site analysis to the design development) added to a strong component of design communication and storytelling. In the book Design is Storytelling, Ellen Lupton states storytelling’s capacity of helping products hook the imagination of users and invite actions and behaviours: “What excites me about design, is the potential to transfer information into someone else’s mind” (Lupton 2017).

In the previous chapter, it was stated that one of the foundations of the issue (Suburban Sprawl) is cultural, originated with the ‘Australian Dream’ of detached home ownership. In order to help to shift from a Sprawl urban form to a more compact city, the consumer market must initiate a demand for more multi-dwelling housing units. Design plays a significant role in this transition, but it is also highly influenced by economy and policy.

“What excites me about design is the potential to transfer information into someone else’s mind” Ellen Lupton, 2017

GOOD STORY

In his book Dark Matter and Trojan Horses, Dan Hill advocates strategic design as a tool to enable systemic change. Design can reshape cultures of public decision-making at the individual and institutional levels when it is applied to the primary problems of the 21st-century governance, which he calls the dark matters (Dan Hill 2015). Stating that design has been wasteful in its core proposition, the Executive Director of Future for the Future Cities Catapult pushes for design as a “culture generator”, by its power of “uncovering, shaping and conveying alternate trajectories” (2015).

The climate emergency is an example of a dark matter, a wicked problem formed of multiple different issues. In its complexity, Suburban Sprawl is a physical manifestation of how designers and policy have failed to address problems by not leading towards more sustainable CREATE cultural behaviours. Problems of policy, culture and economy need to be DEMAND addressed to start to resolve the climate emergency. By focusing efforts FOR MULTIon these areas, we can re-establish harmony between society and nature, DWELLING and begin to undo the environmental damage of post-colonial society.

REAL-LIFE SCENARIO

As stated earlier, the Victorian Government has started implementing design standards for apartments and their relationship with the neighbourhood. The policy side is structural in guaranteeing quality and democratic design outcomes (Martin 2012). Government funding to affordable housing programs, such as the co-operatives presented in the precedent study and initiatives like the allocation of a percentage of social housing to certain developments would begin to shift the patterns of an ingrained profit-led real estate market, changing its economic structure. Does this initiative come exclusively from higher-up, or is it a responsibility of the population to demand more? If so, the first step is to create awareness of the possibilities. Design also has an educational role.

Walking alongside policy and economic structures is the market’s demand. If multi-dwelling units available are similarly priced to singledwelling units, do not present any special design feature, and do not provide any particular quality of life improvement, the number of approved medium to high-density buildings will not rise. Design plays a crucial role in advocating for better outcomes that display how a quality design provides both social and ecological improvements. To achieve that, the design must be good, and a convincing story must be told.

INVESTIGATE AND PUBLICIZE VIABLE ECONOMIC ALTERNATIVES

How, then, can design inform culture? How can a design solution reach far beyond its physical organisation into encouraging new mindsets? Although not simple, the answer relates to design’s educative potential, through its ability to create spaces that enable people to interact, reflect, exchange and question. In a realistic scenario, the designer would also mediate between parties involved in the process.

Mostly during community engagement events, designers would have the opportunity to learn about the demands and showcase relevant parts of the proposal, gaining approval from one party that would help take crucial design interventions forward. As an academic exercise, and therefore lack of direct contact between the designer (me) and the public, this proposal seeks to illustrate in the final video content the relevant findings that proves this work’s two main goals.

“Achieving preferred (rather than probable) outcomes requires rethinking old habits and pushing past the status quo” (Lupton 2017).

To highlight how design plays a crucial role in assisting in the transition from suburban sprawl to a more sustainable city and to achieve an innovative medium-density housing with high environmental standards and social outcomes, this research adopted a strategy that first identified suitable locations for densification, and then investigated a case-study example of higher density urban renewal.

CREATE DEMAND FOR MULTIDWELLING HOUSING UNITS

‘Home builders cop a lot of flak and are accused of producing housing that is unimaginative, lacks innovation and is of poor design. The reality is that home builders are retailers and provide an affordable product to a consumer.

The biggest challenge is to get consumers to be more daring and challenge the status quo. Consumers, who demand a well designed, adequate, energy efficient and responsive home will ultimately be served this. Our livelihood depends on meeting our clients’ demands.’

Dale Alcock, 2008 65

DESIGN METHODOLOGY

DESIGN METHODOLOGY

The methodology employed in the design process was based on eight points. It started with the determination of specific criteria to find the most suitable areas for densification and by the development of a data-driven planning process. The choice of a prototype site that met the criteria was followed by extensive site analysis and review of its urban design framework, examining all documentation released for

PLANNING CRITERIA WHERE SHOULD DENSIFICATION HAPPEN? A sustainable Melbourne can be achieved through densification of suitable locations, chosen based on physical and cultural attributes.

The physical attributes were infrastructure supply and land use.

Demographic data was vital in order to evaluate fitting locations from a cultural lens. Infrastructure supply and land use spatial data were overlaid using GIS. The flowchart on the next page explains the technical approaches involved in this process. Once the maximum extents for densification were set, demographic data was overlaid and the level of suitability established, which created a strategic framework with three implementation phases. The City of Melbourne (2016) is the only Council that released data for its High-Rise Residents profile (Fig. 47).

This demographics data influenced the development of relevant criteria used for the selection of the areas: Population age and household type: 20-29 years and group households are the primary demographic in existing high-rise residentsâ&#x20AC;&#x2122; profiles, with 30-39 years and childless couples in the second place.

Education level and occupation: Employed professionals with bachelorâ&#x20AC;&#x2122;s degrees are the majority within this housing type.

Mobility patterns and existing transport infrastructure: People without any motor vehicle are the biggest group, highlighting the link these residents have with public transport and bicycle infrastructure.

Presence of community facilities and social amenities: Demonstrating possibilities for a social engagement that extrapolates the backyard and could see the advantages in prioritising communal outdoor areas over private ones.

Political inclination: With less conservative zones being more susceptible and open to change.

Heterogeneous land use neighbourhoods: With the presence of different typologies from the traditional detached housing enabling more diverse interventions

Although these characteristics do not reflect the majority of Melbourne’s current population, they are relevant to guide which locations would be more open for change. Fig. 48 shows the GIS flowchart used in the process of overlaying all the mentioned criteria to achieve the most suitable areas for densification. Within Melbourne’s urban area, an initial boundary was defined by creating a 500m buffer from all public transport, excluding a 300m buffer from watercourses and water areas. Over the established maximum boundary, GIS ranking overlays were used to identify regions closer to the land uses associated with commercial zones, health and community, mixed-use, educational and public space and distant from green wedges, conservation areas and rural conservation zones. Heritage overlays and neighbourhood character zones represent areas with stronger cultural significance and, therefore, not targeted as focal points for densification. As they will represent pockets in between bigger densification areas, their interfaces

should be analysed with a closer lens. The capital city zone was also not included for its saturation. The classification of these areas as most suitable for densification is, nevertheless, a general view and each nomination of a site would need to be analysed in more detail.

In order to identify which areas would be more suitable in the first stage of the strategic framework, the demographic criteria were employed. The maps on the next page show the overlap of the demographic information collected from the Australian Bureau of Statistics - regarding the specific criteria defined by the high-rise residents profile - with the suburb they are associated with. Their connection with the specified criteria determined the first, second and third stage of the strategic framework.

The methodology employed to illustrate this framework was specially elaborated by the understanding of the cultural sphere as a fundamental element for a quality densification process to occur.

CASE STUDY: FITZROY GASWORKS

74

Among all suitable areas highlighted in Phase 1, one site with the potential to become a prototype of a role-model higher-density mixeduse urban development was chosen: Fitzroy Gasworks. Historically, the site was used to supply gas to Melbourne from 1859 to 1927. Gas continued to be stored on the site until the 1970s. An extensive and expensive process of soil remediation, with around 10m of excavation, is currently being undertaken (Enviropacific 2020). The site is located only 2km from the CBD and has multiple characteristics that underpin its successful outcome to serve as a role model.

4 ANALYSE

SITE ANALYSIS The site is a former Gasworks that is now owned by the State of Victoria, who is advertising it as a new vibrant neighbourhood to be created at the junction of Fitzroy North, Fitzroy, Collingwood and Clifton Hill (DV 2018). Positioned between Queens Parade to the north and Alexandra Parade to the South, Smith Street to the east and George Street to the west, the site is surrounded by a mixed urban fabric. The north has mostly low-rise residences, with occasional new multi-dwelling units, generally 3 to 4-storeys. The south has a mix of heritage and industrial sites with increasing number of higher-density buildings. A robust neighbourhood character permeates the entire area, associated with a continuously changing atmosphere, given the development pressures taking place.

Being a former brownfield site - and in the middle of an expensive process of soil remediation - the block presents almost a blank canvas, allowing for an in-depth exploration of possibilities. As a 4Ha publiclyowned space, it has the potential to achieve more significant outcomes than smaller plots managed by traditional developers. Its proximity to the CBD and availability of transport infrastructure makes it a connected part of the city, not only benefiting from its context but with the scope to supplement it. Close to several commercial strips- Smith Street, Brunswick Street, Nicholson Street, Johnson Street - besides the remarkable cultural scene existing in Fitzroy, the site feels like an island in a bustling, vibrant neighbourhood. Added to all those factors is the provision of green spaces around it, with Edinburgh Gardens only 300m away and other larger parks (Yarra Bend Park, Carlton Gardens, Princess Park and Royal Park) within a 2km radius.

HISTORIC CONTEXT Built in 1859, the Fitzroy Gasworks was a key supplier of gas to Melbourne. Once other gas companies consolidated, the site lost its competitiveness due to the distance from the port, closing in 1927 . The site remained in operation as a workshop and gas storage facility until the 1970s, maintaining its relevance to Fitzroy and Collingwood’s working class. Two heritage-listed constructions exist at the site, the Valve House and the J H Porter iron building (removed before the remediation works began), which remained as the City of Yarra Council depot until 2018.

A mural painted in 1986 by Melbourne artists Eve Glenn, Megan Evans, and a team of helpers, From Bonbonniere to Barbed Wire (also known as “the Women’s Mural”) was perhaps the largest feminist mural in Melbourne from the second wave feminism (WMDP 2018). The original mural project began with community consultations in 1985 and 1986, when the artists spoke with and photographed women in Northcote over a period of several months. A majestic 50-metres long and 12-metre high piece of local women’s images and landmarks celebrated the cultural diversity of the area. After 30 years, the mural was demolished in October 2019 for the site’s redevelopment.

Ranging from a 19th-century working-class space, 20th-century Council depot with a significant illustration of feminism in Melbourne, the site also has potential ecological value. A map from 1872 shows a creek running N-S across Edinburgh Gardens, north of the site, and a water drain running E-W along Alexandra Parade, south of the site, being diverted into Dights Falls. It can be assumed that this creek was directed into the channel, feeding later Merri Creek and the Yarra River, and possibly the reason why Edinburgh Gardens was placed there. shows an underground brick culvert across Edinburgh Garden, with the Railway Station going next to it. Alexandra Parade, at that time, had a continuous open-air drain along it, which was later covered and became the central garden beds existing today (Melbourne Water 2017). Around the 1970s, these were used as a recreational space, but nowadays they have become an island in the middle of a never-ending traffic flow that connects the city to the Eastern Freeway.

MASTERPLAN REVIEW The timeline below presents all relevant reviewed documentation and significant events in the developmentâ&#x20AC;&#x2122;s process. With its first Urban Design Framework released in 2008, Development Victoria opened community engagement in 2017, with another two Masterplans issued to date. The 2017 plan presents a comprehensive urban form.

In 2019 another urban design approach was released, with a more general description. The urban renewal project is set for another round of community participation in early 2020 (which did not occur due to the pandemic), and construction works to begin in 2021. The following section will detail the relevant points of these documents.

In 2008 the City of Yarra commissioned and adopted the Urban Design Framework produced by MGS and Jones & Whitehead for the Gasworks site. The document aligns with the City of Yarra Industrial and Business Land Strategy Review (2012) and recommends the rezoning of the area - and adjacent blocks - from industrial to commercial use (MGS 2008). It establishes guidelines for the height, character and infrastructure to be provided in the frontages with Queens Parade, Alexandra Parade and Smith Street. It also analyses issues and opportunities regarding access and connections within the context and provides recommendations for open spaces and recreation facilities.

Finally, it proposes subdividing the four-hectare site into five blocks with a central triangular public space. The document is concerned with height control based on sightlines into the site: “Heights may increase away from street frontages using upper-level setbacks that are not visible from the adjoining street”; or “No overshadowing at mid-winter of the southern footpath of Alexandra Parade” or “Reduce heights rapidly to the east of Smith Street to create a transition to low-rise heritage precinct” (MGS 2008).

This perspective aligns with Melbourne’s cultural tradition of reluctance to higher density buildings, with the most meaningful preoccupation being the facades’ outlook from the existing streets, highlighted by the site’s notable neighbourhood character context.

Alexandra and Queens Parades present a generous width of 60m, with the dense and tall tree canopy dominating most viewpoints on the surroundings, being the most suitable frontages for higher buildings.

Alexandra Parade at the south is especially suitable, where the built form would not impact the large street proportion and structures would not overshadow the interior of the block, with minor overshadow in the adjacent footpath. In that sense, the document fails in providing proper consideration to the impact of the height towards the spaces created inside the development.

In November 2017, a Masterplan - Design Report was released

by Development Victoria. This document shows a more direct approach to the development’s character “Fitzroy Gasworks will be a whole of government approach to Urban Renewal - delivering an integrated, sustainable and thriving urban village showcasing the revitalisation of a strategic inner-city site for a growing Melbourne” (DV 2017). The proposal seeks to address the 20-minute neighbourhood highlighted in the planning documents by providing a series of amenities that add to the city’s infrastructure. It proposes the positioning of a school and sports courts in the north-west corner and the creation of four mixed-use precincts with an active ground floor.

88

Its program becomes more defined, with 1,100 apartments, 4,300 m2 of retail, shops & small businesses, childcare, sports courts, vertical secondary school, live/work units, 14% public realm (excluding streets), 8% active open space and 700 car spaces in the basement.

In terms of the height specification, it recommends lower heights (6-10 storeys) responding to the residential interface (Queens Parade) and taller built form (6-14 storeys) to the south (DV 2017). Again, it shows a more substantial concern with the existing surroundings than towards the spaces that will structure this new ‘Urban Village’. A shadow study is shown with not much clarity, and it is broadly argued that different areas will have varying degrees of sun and shade. A 3D aerial hand drawing presents the general feeling of the space, which seems cramped and hard to read.

In April 2018 a specialist report was conducted by Craig Czarny, from Hansen Partnership, to assess the proposed Amendment C243 to the Yarra Planning Scheme. This aimed to facilitate mixed-use development at the site through the rezoning of the land - from Public Use Zone (PUZ1 and PUZ6) and Commercial 2 Zone (CZ2) to Mixed Use Zone (MUZ) and Public Use Zone (PUZ2) - and introduction of a new Development Plan Overlay - Schedule 16 (DPO16) (GTA Consultants 2018). The rezoning was essential in enabling the site to incorporate residences, commerce and the proposed school. Stating the development’s significance to the broader municipality, Czarny (2018) declares that the site is “well separated from sensitive residential land (with heritage designation) and abuts major roadways (20m-60m wide)” (2018). This point is further detailed when affirmed that, by its ‘island’ structure, the site is large enough to establish its own urban character, not disregarding its context, but signifying “an opportunity for a development outcome that is both ‘contextually referenced’ and ‘distinctive’ in its own right” (Czarny 2018). Czarny points out negative shadowing impacts on public (street), communal (courtyard) and private (balcony) spaces in 2017’s Master Plan and suggests further adjustments to building heights or spatial dimensions (2018). The report further specifies a series of recommendations for the Masterplan and the DPO schedule 16, which were taken into consideration for this project’s development.

In October 2019 Development Victoria issued the most recent version of the project to date while seeking community feedback.

The overarching principles remain similar, with the formal inclusion of affordable housing in the scope (DV 2019). The most significant changes are in the built form and urban design, with a complete restructuring of the buildings’ footprint. However, this latest release does not specify building heights, only suggesting 4-6 storeys along Smith Street.

89

The three published Masterplans presents very distinct approaches to the built form. While most designs were shown on a high-level perspective, an interpretation of their content was made and converted into 2D and 3D formats.

Ground plan overshadowing during the winter solstice

•

Communal outdoor spaces to residences

•

Scale of public spaces and viewshed

•

Access and connectivity

In order to evaluate each point, the buildings in each Masterplan were modelled, and a sun study for the winter solstice was done, since it characterises the season where the buildings overshadow the most. The schedule below shows the floor area per number of storeys, total area of communal and public space, estimate of the retail and residential area, with the total number of dwellings each proposal would fit. The number of dwellings/hectare was established for each, which highlighted the average density proposed by the development. None of the released Masterplans was specific about height or building area; therefore, the modelling and schedule creation was an approximation based on the investigation of the available information. Half of the ground area was considered as retail/office space, and the other half residential. The number of total dwellings resulted from considering an average of 90sqm per house - which could range from a 60sqm to a 120sqm (Secret Agent 2020) - and excluding 20% of the total area for circulation. The dwellings/hectare was a result of this number divided by the 3 hectares site.

The analysis of the best time - 1 pm - in the worst day of the year - the winter solstice - highlights the constraints in each proposal. While the UDF from 2008 performs the best distribution of communal and public space (it was assumed that the scheme comprised perimeter blocks), the Masterplan from 2017 shows unsatisfactory sun conditions in its internal courtyards. The proposal from 2019 aims to address that, but only achieves a positive outcome for its primary public spine, with very fragmented remaining outdoor spaces. This latest release appears to meet neither desirable sun conditions to its outdoor spaces nor its building facades. Moreover, it looks to disintegrate the ground level into narrow and underutilised spaces, creating a deficient user experience through the development.

QUESTIONING THE BRIEF The development has gone through a long process of urban design iterations, specialists reports, community engagement and rezoning, with a considerable amount of requirements and goals being established towards the site. This project’s extensive analysis of the proposed schemes - especially in the 3D modelling process and subsequent schedule creation - highlighted the opportunities and constraints in each.

The global precedents previously analysed created parameters for density comparison and were important to reveal that the 367 dwellings/ hectare proposed by Development Victoria were too dense. Fitzroy Gasworks represents a unique place in a very specific context and with particular elements in its program. The senior school for 650 students in its NW corner, the aim to become a role model for sustainable developments, the requirement to provide high amenities and public space to residents, and the broader community make this a nonstandard residential development. Since it aims to achieve such a high number of different uses and there is no suggestion that one skyscraper could host most residences, it is expected that it will not be able to achieve very high levels of population density.

Combined with those findings, two documents were taken into deep consideration while defining a new design approach. The Development Plan Overlay 16 is an official document approved by the Planning Minister in July 2018 that allows for the site’s rezoning into an educational and mixed-use zone and establishes high-level guidelines for its development. The DPO16 was included in the Yarra Planning Scheme through the Amendment C243. The community group in dialogue with Development Victoria was ‘Protect Fitzroy North’, and their resolutions were presented in a public hearing held in April 2018, which led to a document called ‘Protect Fitzroy North Resolutions’. In conversation with the ‘Protect Fitzroy North’ President, who is also a

member of the community group formed for the new development, the resolutions presented seem to have been mostly taken into consideration.

A summary of those documents have been made and are illustrated in the following diagrams.

Although much more extensive, the documents were narrowed into six categories: open space, housing, character, infrastructure, performance and transport. Since this work investigates the development from a landscape architecture point of view, these categories were chosen due to their relation with the field and the following design intervention.

Overall, both documents state a need to respond to Queens Parade and Alexandra Parade as formal boulevards and retain specific views toward the context and landmarks (YPS 2018, PFN 2018).

There is also a clear intention to prioritise active modes of transport at the ground level, allocating car traffic and parking to the underground (especially given that the soil remediation process required 10 metres of excavated soil in many points of the site). Both also declare that the future development must enhance a community-oriented lifestyle with plenty of community infrastructure and a precinct with a sense of identity.

They establish different building-height controls but agree in allocating 15-20% to affordable housing. Finally, with distinct percentages of the site designated to open spaces (8%-25%), they concur that the urban renewal must be a model for sustainable innovation. The community groups also brings the Green Star Rating as a tool for measuring its performance. The Green Star Rating System is an internationallyrecognised sustainability rating system launched in 2003 by the Green Building Council of Australia. It provides four tools available for certification of design, construction and operation of buildings, fitouts and communities (GSBC 2016).

DESIGN APPROACH The integration of top-down (DOP16) and bottom-up (Community) approaches were critical to structure the design intervention. The Green Star Rating criteria for communities and performance was analysed and organised in the three pillars identified as crucial to achieving a landscape-oriented urban development: environmental, social and economic. Each category was also split into empiric perceptions of how much of the scope is subject to design or governance. That division aims to illustrate how design has a more influential role in the outcomes related to the environmental and social spheres - although governance also plays a crucial part - and how much governance is structural in guaranteeing an economically sustainable precinct.

design can undoubtedly facilitate the adoption of a particular economic framework, but will unlikely be able to sustain it alone.

Moreover, governance might benefit immensely from a strategic design program, which could help to build a sensitive and resilient business plan for a specific area. This point falls out of this work’s scope.

The process elaborated in this thesis will focus more specifically on the environmental and social spheres, with some general identification of key sustainable economic strategies.

The points extracted from the Green Star Rating were merged with the points from the DPO16 and community group resolutions and formed the criteria for later analysis of the design outcome, divided into six categories:

INTEGRATED WATER SYSTEM

In order to achieve the best outcome balancing social, environmental and economic spheres, the design approach focused on BUILDING ENVELOPE the conception of a landscape-oriented urban development, considering landscape the physical space where all spheresCOMMUNAL (social, cultural, SPACESpolitical, ecological and economic) collide. The line of thought that guided the BIOPHILIC program’s development started by the primordial need ARCHITECTURE to start reversing the ecological damage Melbourne’s industrial phase created. Although SPINE the two-year-long remediation process aimed CENTRAL to remove all toxicity from the ground (Enviropacific 2020), specialists report that sites with PLAZA previous Gasworks uses cannot be remediatedHERITAGE entirely (Kabay 2010). In order to promote a continuous purification of the soil and groundwater, ACTIVE FRONTAGES phytoremediation processes alongside an integrated water system are crucial to allow for a healthy environment. UNDERGROUND CAR FLOW As mentioned previously, the former creek that could be seen in BICYCLE ROUTES the 1872 map of Edinburgh Gardens was channelled in the early 1900s.

Recently it has been brought to the surface through the rain garden that PEDESTRIAN CONNECTIONS crosses the park and then becomes piped until it reaches Alexandra Parade stormwater underground drain before TREE it is diverted Dights CANOPY into COVER Falls. This project’s first design move is to bring this back to the surface, integrating it into a network of wetlands and swales within the precinct with adequate plant species for phytoremediation processes. This water system is connected to the buildings, with rainwater harvesting and wastewater recycling. The segment of Alexandra Parade’s underground drain that meets the precinct is also opened to the surface, configuring an open-air stormwater swale. The stormwater and wastewater coming out of the development are directed into the water treatment system before diverted into Alexandra Parade. Although this intervention on Alexandra Parade only affects a single block, the idea is to advocate for the complete transformation of this underground drain into a linear park, improving not only ecological processes but enhancing the city’s liveability and its social spaces.

In regards to the building’s footprint, the 1100 dwellings proposed

by Development Victoria were considered too dense not only in comparison to the surroundings but mainly to global precedents with notable quality of life (refer to page XXX). The amount of quality public and communal outdoor spaces were considered of utmost importance to allow for a distinctive precinct, with overshadowing in the winter being a key criteria for evaluation of buildings’ maximum height. Using the same sun-analysis process to evaluate the proposed Masterplans, the design investigated the maximum building envelope without affecting the quality of its open spaces.

In order to assist in a smooth cultural transition from the combined detached house + private garden, the allocation of communal spaces integrated to all housing was considered essential. These spaces may vary in size and components, and it is fundamental that its administration should be managed by residents. It is understood that there is no right formula to what a communal space needs to have and that the best outcome should be the result of a participative project. However, as the design presented in this work aims to illustrate the relationship established between the residential private and communal spaces, and the possible interstitial threshold areas created, it investigated possible design outcomes for these spaces.

Although outside of this projectâ&#x20AC;&#x2122;s design scope, some points regarding the architectural components are specified, as it is considered they are highly relevant in achieving the desired outcome. As stated in the community group resolutions, all apartments should follow the BADS Standards, and the overall building constructions should employ Biophilic Architecture principles: the incorporation of natural lighting and ventilation, vegetation, integrated water and waste systems, passive energy and other elements for creating a healthier built environment for people. Although not represented in this work, all building area must be divided into different designers for a diverse and inclusive outcome.

The public realm must be attractive, safe, integrated with community infrastructure, retail and office spaces. Two main public spaces are proposed: a central square associated with the water system - for educational and sensory stimulus - that is connected N-S through a central spine, and a heritage plaza, that incorporates the heritage Valve House building.

In order to blend the block into the city fabric, but also provide the required amenities for its residents, main street frontages should incorporate retail and offices spaces. Each one of these frontages (Queens Parade, Alexandra Parade and Smith and George Street) have different interfaces and scales, and therefore should be thought of in relation to their adjacent contexts at the same time as the relationship they establish with the inner-block.

102

Advocating for active and sustainable modes of transport, the precinct will have a new tram stop at Smith Street, be supplied by a rich network of bicycle and pedestrian routes, and establish its ground level as a car-free space. As the soil remediation process had to dig up to 10m of soil in specific areas, this 3-storey underground space will be allocated to all car traffic, with access to all commercial, residential and educational buildings, and necessary car parking spaces. Access to the underground level is via George Street and Queens Parade. More than supplying the inner block with pedestrian and cyclist-friendly tracks, the siteâ&#x20AC;&#x2122;s redevelopment aims to restructure the transport network on the surroundings, reclaiming the street level from the constant car-flow and adding pedestrian crossings in Queens Parade and Alexandra Paradeâ&#x20AC;&#x2122;s frontages. It also consolidates the currently fragmented bicycle routes W-E in Queens Parade and Alexandra Parade - with the proposition of a central linear park with a bike path (similar to the one on St. Georges Road north of Merri Creek) - and N-S in Smith and George Street, which have exceptionally narrow bike paths nowadays.

Finally, the proposition of vegetation in abundance was considered crucial to achieving the projectâ&#x20AC;&#x2122;s goal. In response to the heat island effect, tree species that are suitable for a changing climate are to be extensively planted, providing a consistent tree canopy cover of at least 40%. All swales and wetlands should incorporate both phytoremediation and other plant species, considering diversity is key in establishing a healthy ecosystem and creation of wildlife habitat. Vegetation is also to be used as a buffer from car-traffic zones and as green fences guaranteeing privacy towards the residential spaces. Communal spaces are encouraged to have greenhouses and community gardens for a yearround planting of edible species.

DESIGN DEVELOPMENT The first step of design development involved the definition of the building footprint and heights. The parameters taken into consideration were the same as the ones used in the masterplan reviews: •

Ground plan overshadowing during the winter solstice

•

Communal outdoor spaces to residences

•

Scale of public spaces and viewshed

•

Access and connectivity

A similar massing and sun study was produced for three new iterations, taking into consideration the opportunities and constraints from the presented masterplans and the approach defined in the new program.

While reviewing the masterplans and global precedents, the use of perimeter block as an urban typology stood out as providing the best spatial resolution between public and private realms, through the use of the buildings to delimit and accommodate the required communal spaces. It also allows for a structured network of streets and a continuous building facade, even if broken into different buildings with different heights. That was the initial premise to create building plots. Higher buildings were initially allocated in the south and east looking to have the minimum overshadowing possible into the outdoor spaces.

The first iteration presented an unsatisfactory solar outcome for the communal space adjacent to the Valve Plaza, which was redesigned for the second iteration. The block to the NE was also too low, and one storey was increased for the second iteration. The communal spaces in the SW corner had improved their solar exposure in the winter solstice, but the upper storey obstructed solar access to the NE block. The third iteration provided a cut created in this block in order to allow for the entrance of afternoon sun.

The same schedule with the same parameters was created.

Overall, the three iterations have a built area of around 58% of the site with densities varying from 200 to 260 dwellings/hectare. The third NUMBER OF STOREYS AREA iteration3was considered as achieving the most desirable result between 4 5 6 8 10 12 14 the parameters and was chosen to be further detailed.

8 DETAIL

The Landscape Structure plan shows in a diagrammatic way how the development is being structured in this draft proposition. With around 260 dwellings/hectare, the proposal still achieves a very high density without compromising the provision of quality outdoor spaces.

The architecture plan was sketched to understand how the apartments could be arranged. In this case, all apartment units have balconies facing in and circulation corridors facing the street, having, therefore, cross-ventilation and solar access. However, the architecture should be divided amongst several practices to guarantee a diverse product. As a landscape-oriented proposition, the detail of the building blocks will not be a part of the scope.

Alexandra Paradeâ&#x20AC;&#x2122;s underground drain becomes a swale that cleans stormwater before directing it into the Yarra River system. The main pathway that crosses through the new precinct runs concurrent to a wetland and swale system that receives the piped water from Edinburgh Gardens and brings it to the surface. Towards Queens Parade, a crossing over the wetland allows people to interact with their natural environment.

The Queens Parade and Smith Street fronts are activated through retail and office spaces, drawing the city into the block, but also providing the required access to amenities for its residents.

The access to the main square through Smith Street shows another perspective, with the sloping lawn and bleachers centred around a cascading water feature, providing both ecological and social benefits.

The water feature also incorporates elements of the previous Gasworks site overlapping its natural heritage with its post-colonial history, creating a sense of site identity. Community-dedicated spaces in key locations help foster the creation of collaborative connections between residents and the local community.

Going back towards the Alexandra Parade entrance, the site features a heritage element, the Valve House. Refurbished into a gallery, it is the main entrance to another public space, the Valve Plaza. With co-working spaces and creative industries, this space is activated with views towards Alexandra Parade and the city. A pedestrian crossing to Alexandra Parade reclaims the street level from the car flow, reconnecting the block into the city.

During the development of the project’s 3D model, a few issues regarding the proposal were identified. The most significant problem was the lack of connection between the two main public spaces, the central square and the heritage plaza. While producing the walkthrough model that explained how the spaces are connected, there was an evident difficulty in accessing the Valve House. Although this space is related to the new linear park on Alexandra Parade, especially with the new pedestrian-crossing, it felt separated from the rest of the precinct.

Other issues related more to detail than to the block’s general scheme.

The pergola attached to the Valve House seemed to have dominated the heritage element, and therefore would be removed. The historic element on the central square’s water feature was too big and needed to be detailed further. The main wetland north to the precinct had a man-made appearance, while it should resemble a more natural setting.

Other elements were lacking detail and a more realistic representation, which would be approached later in the project’s development.

Iteration four represents the final outcome of the draft proposal, which underwent minor adjustments from iteration three, when the buildings’ plot was further detailed. Two new schemes were modelled, now creating direct access between the two main public spaces. The first attempt was unsuccessful in creating a communal space with sufficient amount of winter sun. Another iteration facing the communal space to the north - rather than the south – achieved a better outcome.

8 DETAIL

DESIGN PROPOSITION The final design proposal demonstrates how a landscape-oriented urban development provides the best outcome balancing social, environmental and economic spheres. In this chapter, the design will be explained over a walkthrough the site. The entire walkthrough can be visualized in the video found in the link: HTTPS://YOUTU.BE/FL0-VWFBKMO

DESIGN APPROACH 120

In this chapterâ&#x20AC;&#x2122;s last section, the criteria used for evaluation will be analysed in detail, highlighting how each point is developed in the design.

LANDSCAPE-ORIENTED URBAN DEVELOPMENT 121

In a birdâ&#x20AC;&#x2122; s-eye-view looking from Queens Parade, we can see how the development is structured. It is important to state that the architecture component was only modelled to illustrate its relationship with the landscape, and do not aim to represent the desired outcome.

As mentioned before, its design should be divided amongst different

122

practices in order to achieve a diverse and inclusive outcome. In the landscape structure, the central spine defines the spatial distribution. It is the main circulation, connecting the two existing boulevards, and also the most significant ecological system. Run-off from the surroundings and stormwater from the underground drain are directed into the first

123

pond, after going through a gross trap pollutant located underneath the pedestrian and cyclist W-E pathway. The wetland system is composed of four cleaning pools, separated by pedestrian crossings, with different degrees of vegetation as buffer zone, according to the level of toxicity present in each stage. In case of severe rainfall, overflow is diverted directly into Alexandra Paradeâ&#x20AC;&#x2122;s swale.

124

Phytoremediation occurs through plant species that perform rhizofiltration processes, cleaning the water by filtering pollution through their root system. A secondary network of swales branches throughout the entire precinct, collecting greywater from the mixed-use precinct and treating it before diverting into the wetland axis. After the fourth pond, the water becomes clean of most toxicity and is exposed in a water feature that defines the main public square.

125

A sloping lawn and rock seatings are encircled by Jacarandas on the southern side â&#x20AC;&#x201C; to not overshadow the space - and cascading water on the other. Trees to the north are deciduous and will not create shade in the winter. The upper side of the water feature creates the visual link of the square to the heritage plaza, the two main public spaces. Native trees and drought-tolerant plants create a robust landscape for a changing climate. Sculptural elements illustrate the connection between the past (pre-colonial), present (post-colonial) and future, the precinctâ&#x20AC;&#x2122;s identity. The core of the

126

precinct is to be designed with community consultation, shaping its character from a bottom-up approach. The allocation of a community space in this corner is crucial to safeguard its community management and activism.

Heading south, the tall central Eucalyptus provide a transition between the native-style boulevard that exists inside the precinct and Alexandra Paradeâ&#x20AC;&#x2122;s existing boulevard of Elm Trees. The water feature becomes a shallow linear pool that diverts water into Alexandra Paradeâ&#x20AC;&#x2122;s swale.

127

With mostly a residential character and the occasional retail, this boulevard provides public gathering areas for dwellers and local community while providing economic opportunities. Entering one housing unit, we can explore how the proposed communal spaces are structured in the precinct. Illustrated as a composition of a traditional Victorian style with contemporary elements, the architecture here is meant to represent how higher density is not a synonym to high-rise and does not have a specific

look. With different sizes and spatial arrangements, all apartment units have balconies facing in, and all ground floor units have direct access to the communal garden, shared between all residents from that building block. A private transitional space creates a threshold before the shared area. Each resident is entitled to decide how to organise this space, if they will put fences for children and pets, for example, or what degree of visual permeability they want in order to guarantee their privacy. The shared

128

space, however, is managed collectively. In this case, in a participatory design process, residents decided for a multiple-use greenhouse, outdoor food production, firepit area, play area and an orchard. Different components require distinct management levels, and it is up to the residents to decide how this will be structured in community meetings.

A loop trail goes around the garden, creating space for walking. Plant species have sensory traits, are edible, bird-attractive and robust for a changing climate.

Rainwater is harvested and directed to a retention system installed in the basement, which also re-uses wastewater for irrigation and toilet flushing, reducing water consumption by 50%. A waste management system is also integrated into all vertical circulation. Part of the organic waste is selected and put into a compost and worm farm that generates fertiliser for the planting. The greenhouse is located in the centre of the garden and is an open and creative space. They are used to grow food and indoor plants, as a maker space and also for collective movie projections.

129

The residents of this block also decided to allocate some space for a firepit, with local rocks used as boulders for seating. All balconies have built-in planters, creating more possibilities for a biophilic architecture component. The play space has a softfall rubber ground and wood structures interconnected with ropes and swings, providing a safe play area for different age groups. Parents can take turns in who is monitoring

130

the children, allowing for more alone time while supporting their children to develop autonomy and risk assessment. The play area is directly connected to the common kitchen area, where dwellers can organise meals together or host events. An orchard was planted in the northwest corner, where the communal garden meets the public square. This provides a visual and sound barrier from the outer space while supplying fresh fruits for the residents.

131

Leaving the residential block now heading to the Valve House Plaza we have other illustrations of the interfaces established between the residences and public space. The building to the left shows a mixeduse typology with cafĂŠ in the ground level and housing in the upper levels. The building to the right has two public frontages, one to the pedestrian street and the other to the Plaza. The pedestrian street front has only residences while the Plaza front has co-workings and retail on

132

the ground floor. The timber cladding provides privacy to the residential circulation corridors while allowing light and wind to flow through. The vegetation strip in the middle is part of the swale system that treats runoff water before taking it to the primary water system. As the sun sets, the Valve House Plaza shows its night activation. The heritage building is retrofit into a gallery that hosts a permanent exhibition about the siteâ&#x20AC;&#x2122;s historical and temporary exhibitions from different artists. The native Illawarra Flame Tree exhibits its colourful presence as the central element of the space, with the red flowers and green foliage complementing red metal pipes and bricks from the Valve House. Boulder seatings with local rocks defines more gathering spaces, used day and night. The presence of coworking spaces and retail showcases the economic opportunities within the precinct, which can be used as a workspace by residents and the local community. The pattern created with the paving is a wayfinding element that guides people through space and punctuates specific sightlines to the city, the Shot Tower and, at night, an exhibition opening from a New Zealand graffiti artist.

133

The pattern also guides the flow towards Alexandra Paradeâ&#x20AC;&#x2122;s pedestrian crossing, reclaiming the street level from the car flow and reconnecting the block into the city. The residential rooftops are used for electricity generation, food production and create diverse social gathering opportunities.

134

Alexandra Paradeâ&#x20AC;&#x2122;s intervention, here represented in a single block, advocates for the complete transformation of this underground drain into a linear Park, improving not only ecological processes but enhancing the cityâ&#x20AC;&#x2122;s liveability and its social spaces. A site that once polluted the air, soil and groundwater can now clean water, provide wildlife habitat and vegetation in abundance, while creating healthy community-oriented spaces and fostering environmentally sustainable economies.

135

This work’s final section comments on the design outcome according to the design criteria established earlier:

OPEN SPACE •

Ecological value The wetland and swale system provide water cleaning before reaching the main watercourses, preventing the pollution of main water systems. They also create wildlife habitat and ecosystem restoration.

•

Heat island effect The final proposal presents 50% tree canopy coverage, which is the ideal amount to offset urban heat island effect (REF?).

•

Safe social places The allocation of mixed-use ground level with activation day and night encourage safe social spaces.

•

Overshadowing The maximum building envelopes were determined to prevent overshadow of open spaces. All communal gardens and main public spaces were tested in the worst scenario - the winter solstice - and showed a satisfactory amount of sunlight.

HOUSING

•

As the detail of the architecture lies outside of this work’s scope, the points highlighted in this section aim to show key considerations in the successful realisation of the proposal.

Sustainable buildings

In this proposal, buildings are represented with a lot of green to show the potential of facades and balconies to receive planting. Green walls system are not considered sustainable approaches (high-maintenance and water/ energy usage), but the use of climbers are. Planter boxes inbuilt in facades and balconies are great to assist in thermic and sound insulation. They can also provide visual enhancement and food production for people and wildlife. Other sustainability points are declared in the BADS Standard.

•

20% affordable housing Stated in Development Victoria program, this point is affirmed here as a structural component of the project’s ethos to fight the housing affordability crisis.

•

136

Compliance with BADS Stated in Protect Fitzroy North community group resolutions, the compliance with both BADS and Better Apartments in Neighbourhoods is considered elementary.

CHARACTER •

Culture, heritage and identity As a direct component of community participation, the proposal does not specify particular cultural approaches in creating the precinct’s identity.

Rather, it mentions opportunity in spaces and concepts that could direct possible interventions. The use of the Valve House as a gallery and its Plaza for creative and commercial purposes fosters the creation of a place to develop new identities over existing historic elements, which is culture’s role.

A sculptural element in the precinct’s core is suggested, where the visual link of the two main public spaces occurs. Although there is no defining characteristic of this component, it is suggested that it should be developed by an artist chosen by the community over participatory workshops. It is also stated that the character of this element can relate to the site’s pre and post-colonial conditions, or could be in memory of the feminist mural that existed in the site for over 30 years, but these choices should be made by the community.

•

Community development The site fosters community development through different strategies. It allocates community-managed public spaces that can perform as places to organise public meetings and workshops or even be hired for the local community for income generation. All public spaces are meant for community development, through enabling people to interact, reflect, exchange and question. The same occurs in the communal residential spaces, which are key in orienting a new collaborative lifestyle.

•

Relation with the context The proposal seeks to integrate with the context more harmoniously. The first thing that separates the block from the surroundings is the 60m width of Alexandra and Queens Parade’s boulevards. Three pedestrian-crossings are introduced in each Boulevard, prioritising and safeguarding pedestrian and cyclist flow over cars. The activation of main frontages with retail and office spaces also aims to provide the precinct with amenities at the same time as bringing the broader community into the precinct. The average building height is 4-6 storeys with the maximum being 10 storeys in the school’s corner. That range shouldn’t impact the surrounding neighbourhood character. The position of a new tram stop in the precinct also aims to integrate it into the context.

137

INFRASTRUCTURE •

Healthy and active living Is encouraged through the diverse recreational opportunities, either communal or public, and by fostering more active forms of mobility.

•

Integrated water cycle The rainwater harvesting and retention system in the buildings allow for water re-use, which reduces the total water consumption. The wetland and swale system complements those by cleaning water and providing a sensory experience for users before diverting it into the main watercourses.

•

Waste management Also specified in the BADS Standard are waste management and logistics.

Buildings are to have vertical waste passages to facilitate waste disposal and communal gardens are to have a compost system.

•

Community infrastructure Is provided throughout the precinct with retail, offices, gallery, public and communal spaces.

PERFORMANCE •

Model for innovation With the implementation of all criteria and compliance with the Green Star Rating System, the development should become a model for innovation.

•

Greenhouse gas strategy All buildings are to have minimal construction impact and be energyefficient, minimising the precinct’s footprint. A management strategy should be implemented in order to evaluate the GHGs development and continuously seek for productivity measures.

•

Materials All materials are to be sought locally, minimising logistics efforts and consequent GHGs. The choice for material should also account for their production method, prioritising sustainable options.

•

Sightlines Notable sightlines towards the city and the Shot Tower are guaranteed from key moments in the public spaces.

138

TRANSPORT â&#x20AC;˘

Sustainable mobility In order to foster active modes of transport, all car parking and flow is directed underground, utilising the 10m of soil extracted from the remediation process. The ground floor is left free for pedestrian and cyclist, allocating specific hierarchies of flow and speed.

â&#x20AC;˘

Walkable access to amenities The walkability to amenities is provided within the precinct and in its connection to the surrounding amenities.

139

FINAL CONSIDERATIONS This work has investigated the negative environmental, social and economic impacts of Suburban Sprawl, and explored how Melbourne can double its population without duplicating its footprint. It explored the cultural history that generated the current urban form of Australian cities and how that same culture continues to act as a barrier to shifting to more sustainable cities. It looked into Melbourneâ&#x20AC;&#x2122;s current housing affordability crisis and how alternative housing models can assist in offering solutions.

Through an 8-point design methodology this work has explored the most suitable areas for densification and examined global and local precedents to generate a design case study, Fitzroy Gasworks urban renewal. In order to develop the design the projectâ&#x20AC;&#x2122;s publicised documents were analysed and an evaluation criteria was established based on a top-down (Development Plan Overlay 16), bottom-up (Protect Fitzroy North Resolutions) and sustainability rating (Green Star Rating System) approach. Based on this evaluation criteria, an alternative design was proposed to demonstrate how a landscapeoriented urban development provides the best outcome by balancing social, environmental and economic spheres. The proposal also aims to highlight how design plays a crucial role in assisting the transition from Suburban Sprawl into a more sustainable city.

The design development process utilised 3D modelling as a technique to evaluate different design iterations, in particular by doing sun-studies in distinct building envelopes. It created an analytical breakdown to compare the total amount of dwellings, communal and

140

public space, as well as estimates of retail and residential area for each iteration. The proposal that performed the best according to the criteria was further developed and presented in detail as the final design proposition.

Overall, the final design proposition incorporated all key elements determined by the design criteria and approach. The achievement of a landscape-oriented urban development was created through the balancing of the social, economic and environmental spheres. The environmental sphere was improved through the incorporation of the high tree canopy cover, integrated water network, waste and water management, phytoremediation processes to clean water and soil, and use of locally sourced, sustainable materials. The social sphere benefited from the creation of inclusive, safe and active public and communal spaces. It is also positively impacted by the mixed-use character of the precinct and the non-car-dependency creating opportunities for more active engagement. The economic sphere has been improved by the way the space encourages new sustainable economies and innovation, such as the co-working spaces.

As an academic exercise, the final outcome cannot exhibit in detail the complexity of a real-life design. In a real scenario, collaboration with sub-consultants, the community and client is necessary to accomplish precise results that meet the needs of those who will be using the space.

Nevertheless, within the premise of developing an in-depth design process and showcasing the role of design in advocating for more sustainable cities, this work is considered successful.
