Introduction climate changes call for a new approach for how to adapt urban environments to constantly evolving cities. Therefore, one of the challenges of today’s compact cities is to establish a solid strategy that enhances ‘healthy’ living, and still manages to offer cultural and social qualities with the notion of climate change in mind. The project’s focal point is to embrace new forms of urban typologies, where design meets human needs as well as incorporating water as an element. The issue at hand is to handle hydrological tasks at neighbourhood level in connection to a greater solution strategy for climate changes. Moreover, the project seeks to understand the city as an urban ecosystem and utilize problems of sewer to come up with answers of both aesthetic and technical character. 3
Introduction
Kjærs Mølle is an area in Aalborg, which has the potential to solve these issues. As a former industrial site, the the excavation. A natural landscape habitat surrounds the lake and exists in correlation with surrounding industry, the former freight rail area and a residential area; Kærby. Originally, the project site included the old freight area and Remisen, but to enhance the project, this part of the site was excluded. The freight area has within it a strong sign, because it would dominate the area and not allow a both of the areas to evolve simultaneously and unite at the end of this process. of the current landscape and soil could be perceived as
poor. However, this gives no restrains when considering altering the landscape in a plausible design proposal. Though, regarding a more technical aspect, the question of soil pollution at the site is a problem, and it cannot be ignored if the site should be suitable for providing a thriving, healthy urban ecosystem and sustainable neighbourhood. In a local context, the Municipality of Aalborg designates the site of Kjærs Mølle as a progressive urban development area, which will be kept as a recreational site in the future. The goal is to secure Østerå’s path into the city 2014). In this context, the idea is to create a framework

Theoretical discussion According to the publication ‘Ecosystems Services Come to Town’ by ecologist Gary Grant, cities today occupy around 2% of the surface of the earth, but inhabit more than 50% of the world’s population. This overpopulation/ especially when considering the necessity of healthy living situations within the city. WE NEED NATURE As human beings we need nature in our lives, and as a consequence of the fact that most of us are living in cities, this will then be in the form of urban nature. Multiple tremely essential to living a more satisfying, healthy and meaningful life; it stimulates the senses and introduces a scale suitable for human proportions. 5
Introduction
There is a tendency towards reintroducing the wild and This dichotomy is a way to generate qualities that lack today. But why this need to reproduce the atmosphere of nature within the city? The Biophilic Cities Project is a network whose main goal is to enhance the attention on nature within the urban context and thereby show the importance of incorporating nature when planning cities. It points out 4 recognition arguments to why integrating nature into everyday living is crucial. These are: 1. Important Ties to Place: Recognising the place-strengthrect personal contact and knowledge of the local nature which surrounds one. 2. Connections and Connectedness: An enhancing of car-

ing for place and environment gives meaning and purpose for the user and as well encourages further the caring for others. 3. A Need for Wonder and Awe in Our Lives: Nature seen as an instrument, which stimulates and amaze the senses, and creates a foundation for a curiosity to learn and explore more. 4. Meaningful Lives Require Nature: The awareness of The main theme for all 4 of these arguments is the feeling of community and responsibility which can derive from a greater connection with nature and natural elements in ones everyday living. When nature becomes an integrated part of the city in a manor, that it needs attention and care from the residents, the residents will feel a stronger achieved through shared urban gardening. Incorporating
nature and allowing it to change the city can elucidate the means of nature, and the impact the city has on these natural processes. Furthermore, an ability to create awareness of e.g. hydrological issues in the dense city could be formed by working with water as both a playful and sensorial element to the urban setting. BUT WHAT IS NATURE? When discussing the concept of nature, it is often perceived as the opposite of people and everything mantouched and uncontrollable. But is nature not more? One could argue that everything is a diversion of nature, the only difference is how much has been altered. In the text author Hans Fink argues how one can look upon nature in 7 perceptions, from The Untouched to The Whole. The Introduction

Seeing nature from this point of view as The Whole is thereby also an extreme. It argues that nature is everything; everything derives from something natural and it is not something humanity and the cultivated landscape are excluded from, but rather seeing it all as intertwined. Though, there are many gradients in-between all depending upon the context and the subject/ Denmark consists only of cultivated landscape; even the natural landscape is planned. Multiple trends throughout time have shaped the landscape and created the reality of the Danish landscape. To point out a national example could be the interference with multiple streams in Denmark in the 1960’s. Where streams were transformed from curved layouts into straight channels to optimize the surrounding areas, now only to be changed back again due to multiple unanticipated adverse events upon the
a nature concept it can be placed in one of Fink’s 7 perceptions. It can also be more than just one of the 7 concepts. Here again it depends on the context, and where the observer comes from. Though, the main point is the importance of being aware of the perceptions one bases the discussions of nature management upon.

This is important since programs and functions inevitably will change over time as cities and population evolve. He states that non-programmed use eventually can be of great value to the overall programming strategy 1999). On the contrary, what is not addressed or elaborated in Alex Walls’ theory, are the aesthetic concerns, and also the question of the sustainable city. These issues could have a crucial impact on how the social and cultural aspects take shape and might even hold the solution within them. If one takes nature as a case; it does not ‘think’ about being aesthetic, even though it is a symbol for it. Maybe this is because it is the functional aspects, which are the main focus within nature, and thereby it is actually the mere functionality, infrastructure and the order which makes it beautiful.

It calls for a more innovative way of working with city planning in a sustainable manner, taking both the matter of not continuing the mindless consumption of fossil fuels, when other more sustainable methods are at hand. Therefore biodiversity is a must when designing cities, even within the city borders. In a Danish perspective, this from 1947, where the respect of the nature and biodiversity leaves out large areas which cannot be included in the Again, having a solution oriented approach to this, Alex Wall proposes to imitate the workings of nature by accommodating an ever-changing environment within future city planning methods: “Cities everywhere are competing to retain investment, capital, tax base, population, infrastructure, and amenities.

affords an urban environment where community and sustainability goes together with cultural and aesthetic values, making for a renewal of a liveable, healthy city. The landscape and the city should slide together This is as well an argument from Wall, who sees it crucial to city planning that the city slide into the landscape, and thereby become one whole.
In the paper ‘The Compact City Fallacy’, Professor Michael Neuman addresses the compact city paradox. It argues that: ‘For a city to be sustainable, the argument goes, functions and population must be concentrated at higher densities. Yet for a city to be liveable, functions and population must be dispersed at lower densities.

questions such as, “how do we protect and save the earth from human destruction?” are raised as generators for further investigation and mitigation. Similar emphasis is put into sustainable economic considerations regarding future business development. Environmental and economic sustainability are generally prioritized more strongly than social sustainability, and it is frequently of the reasons why it is a neglected term might be its complicated nature, since it derives from the processes which progress within communities over time. It is the capability of a community to develop structures and processes that inspire future generations to preserve a healthy community: “Social sustainability occurs when the formal and informal processes; systems; structures; and relationships actively support the capacity of current and future generations to create
healthy and liveable communities. Socially sustainable communities are equitable, diverse, connected and democratic and provide a good quality of life Hence, sustainable communities are not only a product of coincidences; it can be designed and should be taken into account in preliminary design phases. Social design is fundamentally planning, designing and developing sustainable, successful spaces that promote wellbeing combined with an understanding of people’s needs. It is important to understand and challenge social dimensions in order for communities to succeed. “Social sustainability combines design of the physical realm with design of the social world – infrastructure to support social and cultural life, social amenities, systems for citizen engagement and space for people and places to evolve craft et al, 2011) Introduction

Transportation networks are essential for people to meet and participate in social gatherings across social class, age urban design are able to shape social life and people’s sense of place. Designing high quality public spaces leads to an enhancement of personal safety in the local community. Creating thriving new sustainable communities in today’s society is a challenge where local needs and circumstances should be considered. Social success is not a given solution, but is obtainable through disciplines such as architecture, planning, economic development, construction and housing management. This again connects to looking upon an area as one whole process, where different functions and events overtime needs to interlock.

Case: nansen park, oslo Architects: Bjørnbekk & Lindheim in association with Atelier Dreiseitl Location: Fornebu, Oslo, Norway Finished: 2008 After Oslo International Airport at Fornebu was re-located to Gardermoen, it left behind a 200.000 m2 area, which needed a transformation and a new purpose. The architects Bjørnbekk & Lindheim designed a park, whose main focus is on water as an esthetic and sensuous factor. Atelier Dreiseitl helped with the design solutions concerning the water. The design of the park is based on the former topography combined with the straight lines used in the airport design. The fjord on three sides surrounds the park. The architects have worked with the peaceful and recreational elements introducing activities and physical exercise. They focused on creating a park with a strong identity and a simple and timeless expression. At the same time, Nansen Park is an excellent catalogue
of creative solutions to the handling of storm water. The park is full of green ditches and other clever ways to lead the storm water into the lake at the lowermost part of the park. Besides creating an enjoyable and recreational park, this area also acts as a storm water treatment area. The architects have worked with several design parameters. One of the most interesting is, how the ground surface meets the water. At numerous places there is a soft, green edge opposite a hard edge, this often shaped in concrete. The contrast presents anew interpertation Other interesting elements in the park are, how the architects worked with the soundscape of water and exploring the idea that water can be a playful and active component. This case becomes an inspirational catalogue of smart and well-functioning solutions to hydrological concerns, which are present at the project site. At the same time it is an aesthetic guideline of how to work with the meeting between a paved, or green surface, and a water surface.

Design Network has taken this landscape typology to into a walkable landscape, stylized and constructed from straight and curved lines that produce associations to the traditional understanding of the Japanese outdoors. Shunsuke Furuie from Design Network explains the role of the landscape architect; �The work of the landscape architect is to create environments, but I think of these not so much as natural environments as landscapes. The word “landscape� suggests the presence or activities of human beings. In other words, I believe that landscape architects should create environments that This case shows how the nature can be interpreted in an urban context. It inspires to working with the beneto solve hydrological issues or to create and interesting landscape with proportions suitable for the human scale.

The challenge of this site is to create a regeneration and community development, which considers passive house requirements and minimization of the A/V ratio of the buildings. The winning proposal re-invents classical 20th century British working class industrial housing into a modern
the existing neighbourhood, creating a new and controversial identity. The row houses differ from the previous by a change in material, and are thereby easily recognizable for residents. The project also revolves around the notion of social sustainability, focusing on creating sustainable neighbourhood. The connected dwellings surround an inner courtyard, a common recreational space. Here a local community core is planned, programmed with playgrounds, swimming pool, a garden and underground parking. The core is a platform for socialization, a safe haven protected by the peripheral dwellings, where neighbours and residents meet and greet and ‘disconnect’ from the otherwise hectic, dense city life. This case inspires to design housing units which are sustainable at more levels. This typology works with sustain-
forms of nature, and by using this shape, section-wise, combined with linked walls, effective dimensions, and deleting corners; the overall heat-loss is minimized. The proposal has a strong architectural character within

This path is the only way to access the lake and the rest of the site. It is not possible to cross Østerå between the bridge next to Hjulmagervej and the bridge at Ny Kærvej. There is a bridge crossing the stream where the old train tracks used to run, but a built structure blocks the passage and makes it impossible to access Kærby on the other side. Along with the tracks running at the western side of the site there is a pedestrian and bike path as well. This path leads to Kærby and the southern suburbs of Aalborg.

borders & Access BORDERS The project site is enclosed by different types of borders. As mentioned in the infrastructure analysis, the site is surrounded by three bigger roads and the railway tracks which have a shielding effect on the site. Østerå is also a barrier which disconnects the lake area at the eastern part of the site from Gabriels and Remisen located in west. Furthermore there is a long wall shielding the lake area from the adjacent industrial area, and a fence running along the pedestrian track from Østerådalen to Hjulmagervej, which prevents people to get access to the lake. Only at two places, this fence opens up and allows pedestrians to walk up close to and around the lake.

green & blue structures The analysis brings out the green elements, which lies in close perimeter of the site. In the analysis it is both the controlled nature which is framed in parks or similar, and the uncontrolled like e.g. the connection from Østerådalen coming into the site from the south which are highlighted. Moreover it shows the blue elements which again in relation to the site makes for a strong connection to the south and Østerådalen.
Furthermore the analysis shows how the site itself makes out for a green pocket surrounded by city structure.
The interesting part here is, however, also how Østerå almost immediately after the site is subverted into pipes underground, and not used as a blue element throughout the rest of the inner city. This is nonetheless something Aalborg Municipality has addressed in the previous years, which in 2008 resulted in a strategy to open the stream up and use it as an active element throughout Aalborg

Districts of Aalborg city all have their own strong characteristics. In the outskirts the districts Hasseris, Kærby, Gug, Frydenlund, Vejgaard are characterized by being mostly suburban residential 2-plan housing. The traditional dense innercity districts are; Østerbro, Øgade district, Inner city and Vestby. The developing districts are: such as the Shipyard district, the Star district, Eternitten, Godsbanen, Campus and the Habour front. In the middle lies the area of Kjærs Mølle. Where the interesting encounter between the Industry, the suburban Kærby and the more developing thriving Inner city happens. Here the site of Kjærs Mølle needs to have its own identity.

the CONNECTION from ØSterådalen This video analysis elaborates how the green connection from Østerådalen to the site is experienced traveling by foot/bike. It is a green stretch, which together with Østerå stream subverts all the way into inner city. The trip starts in the extensive and recreational area of Østerådalen, which is on the outskirts of the city, and used extensivewith the infrastructure of the city happens at the road Over Kæret. This breaks the green connection, and also makes for and unpleasant break in the path, since the trafside of the road after crossing Østerå. The visibility of this is poor though, and if one is not known in the area it might not be noticed. The next stretch of the path takes the traveller through an area with a smaller scale, and closer to housing on one side, and allotments garden on the other. The path still holds a rich quality of being green and recreational, especially by having the stream following its path
in spite of accessing a denser part of the city. Moreover, this stretch of the path is elevated above the surrounding which gives a good visibility for the traveller. The second and last intersection with a road is at Ny Kærvej. Here the connection on the other side of the road is poor and non visible for a visitor. The last part of the stretch before the site is the most narrow as well as the least stimulating part. The reason for this could be the intrusive industrial area on the left. Lastly arriving and passing through the site, the path is excluded from most of the area, being in-between the stream and a fence.

topography This analysis of the topography highlights the low- and highpoints in and around the area. It gives a clear idea of the longitudinal features, and moreover it gives an understanding of the hydrological movements that occur in the lowest points of the area. Most of the water is not where the lowest points are . The lake is e.g. in elevation 2.5 m. where the creek is in 2 m. height and the lowest points in the area are at a 1m. height. The lowest area, which is furtherst to the west, meets the residential area south/west of the area. This low point within the residential area is also problematic. From a hydrological view, it is interesting that the height increases south of the site. This can indicate that a lot of the runoff stormwater from the industrial area would run into the site and down in the lake or the creek to the west. Moreover, it is noticeable how the topography is at its highest towards the city, and gradually lowers to meet the landscape coming in from the south. Ill. 21

This is based upon the map material found from respectively the years 1880 and 1923 and 1930, which is the High measuring board 2014). The mappings show how water has always been an important element of the site, which since 1851 has been used for industrial purpose and for the mill named

As described earlier, the ing built areas enhance the feeling of a valley-like area, by just having a bit more of height, except for the road Ă˜ster AllĂŠ, which bursts the scale completely. The surroundings moreover give a backyard feeling to the place, by literally having the back against the area, making it this overseen wasteland space, in a very close perimeter of the city center. Within the site the notion of being an old waste yard for the industry from Eternitten is not the present impression. The area is very lush with vegetation and makes for this meadowland. The water element is a feature which is dominant throughout the area and adds to the tranquillity of the place. 27

potentials & challenges The project site holds within it many potentials and challenges. The area is close to the city center and multiple bigger roads, which should make it easily accessible. But in reality the site is bordered by the roads, the train tracks and Østerå. It is only possible to access by foot/bike, and even then one can only enter by the gravel path running along Østerå from Østerådalen in the south to Hjulmagervej in the north. To the east, the site is delimited by a wall, shielding it from the industrial area. The area with the lake is even more enclosed by a fence running along the gravel path, which reduces the access to the lake down to two small entries in opposite corners of the site.

better connected with its surroundings, it will be easier to train- and bus station and the cultural life which is offered in the inner city.
The previous connection running west-east through the site between Remisen and Eternitten is closed and the connection to the city center is hampered by Øster Allé.
Today the site has no clear identity. It is a surplus land with some recreational values, but known mostly of the few people passing through on a daily basis. It is the end of the green wedge coming in from Østerådalen and Østerå as an uncovered stream. From Øster Allé and further in towards the city center the nature becomes only more logical issues caused by the low terrain and the soil which prisingly diverse nature creates a sense of being in a more remote area further away from the city than it actually is.

DESIGN STRATEGY Vision The aim is to transform the given district into an integrated part of Aalborg city, by enhancing the landscaping qualities in the connection from Østerådalen and mixing them with the qualities from living within close reach of the inner city. Thereby creating a strong identity for the district, which enhances the local community as well as the awareness of the area as - the city within the nature. Nature – a recreational factor – has great importance for the area and gives value to it. Through integrating different water solutions and creating a hydrological will be preserved.

This gives an understanding of the development and life of the site and how it works in symbiosis with the rest of the city. The strategy highlights the four following ‘periods’ of the sites lifespan: Before - highlights the importance of creating an awareness of the area and connecting it to the rest of the city, even before construction has begun. Moreover, the aspect of dealing with the soil and the pollution at the place is an important focus at this point. The level of treatment is depending on how polluted the soil is.

The plants, which are picked out as a starting point, is with a theme of having either a fruit that is characteristic for the plant or even an advantage in treating waste water, like the common reed. This is with the notion to encourage a wonder and admiration from the user. The point is to use the greenery as an instrument, which stimulates and amazes the senses, and creates a foundation for a curiosity to learn and explore.

the hydrological stretch The hydrological stretch is a sensorial path through the site. Along this route different experiences relating to water are generated. At some points the water makes a soundscape of dripping, gushing or splashy noises. At other points one can either get directly in contact with the water surface or step out onto stepping stones or small piers. Some of the proposed experiences are mainly enjoyed visually, while others invite to an interaction between people and the water as a playful element. The hydrological stretch highlights the water as an important factor of the site. By focusing on water, an awareness of the impact of climate change and urbanization are planted in the mind of the residents. By implementing this hydrological experience, the aquatic sensation establishes an identity to the area.
The illustration above shows how the last part of Østre Landgrøft will be reoriented and redesigned so it cuts through the site and connects with Østerå south of Gabriel. To make sure the new part of the stream will always contain at least a certain amount of water, it will be supplied with water from Østerå. Calculations can be found in appendix 5.

multi-story housing By working with different typologies it was decided to create multi-storey buildings located at the eastern entrance to the site. The purpose of these buildings is to make a boundary between the site and the industrial buildings. This typology is designed with the intention to offer the residents other features than the cluster houses afford. The criterias for the buildings are as following: - They have to be easy accessible - There will be private rooftop terraces instead of private gardens which need maintenance - The buildings vary from 2 to 4 storeys to bring the scale down - The buildings must be near parking facilities The buildings are accessible from each side, which makes it very easy for walking-impaired residents to get to their dwellings. All the way around the buildings there is a three meters tile covered path. 67
Presentation
Each of the buildings has a private rooftop terrace with equipped with garden furniture and loungers. The buildings are going to vary between 2 and 4 storeys, which makes them very manageable and even though they are supposed to create a boundary towards the industrial buildings, they still take the human scale into account. Most of the parking in the site will be situated around the multi-storey buildings, which makes the distance from the parking to the dwelling short and easy accessible for the residents. The large parking zone in front of the south-western building has a green rooftop with smaller plants and trees. This area functions as a public space compared to the semi-private plateaus between the cluster houses.

EVALUATION
reflection The main focus throughout the project has been the meeting between culture in the shape of the city and the highly cultivated landscape with its processes and dynamic characteristics. This disposition mainly arose from the given site. The site is placed on the border of the inner city, and it still maintains a recreational character. In the process, working with the disposition has been how to implement the qualities of nature within a denser urban setting. The distinction between nature and landscape is their internal relationship and hierarchy. Nature is a given, whereas landscape is a processing of nature. Especially theory of nature has been examined through various sources, and they have provided useful tools in a lines. Alex Walls’ notion of how to look upon the landare linked, has been a crucial focal point when developing the design. This resulted in a new site plan, where the landscape is extremely cultivated and controlled, making for a caricature of nature’s qualities. One might question if the proposed design is the optimal solution for how to merge nature and city. Arguably, the proposal processes ‘nature’ as a landscape, and by doing so, the interface between city ture and city actually intertwine through the naturalistic features regarding the proposed topography, or plateaus. Another reason why integrating nature into the project, is to make use of the conceivable consequences that climate changes might cause, and then turn the perception of climate changes into a positive connotation. Respectively over the past couple of years, a lot of negative aspects have existed regarding climate change – people panicking, and yelling; “there’s water in my basement”, has been the stereotypical experience with cloudbursts. 75
Evaluation
The urban environment has not been able to handle these extreme weather situations, and it is time to design with and not against nature. A sense of adaptability and impermanence adds a quality to the urban environment. An example of how to cope with climate change and create a positive outlook could be the design of a stream, or something like the hydrological stretch, where heavy rainfall will cause a visible rise of the water level providing a physical, but still controlled change in the urban setting. Important for the project was to create a strong identity for the proposed neighbourhood. The choosing of target groups has been a useful constraint and has helped develop design parameters and values that adjust the design. Though, limitations are a factor, since designing to specific target groups might cause a risk of creating “gated communities” which excludes other users. This undesirable effect can be avoided by keeping this risk in mind and by to adapt to future needs. By designing an urban setting equation, and by generating social sustainability through a sense of community and ownership, in the long run, the area will attract others and secure the space from not being a gated community. Even though the site is designed to the needs of the city, and must be so in order to be a useful and well-functioning part of Aalborg. And by specifying the design, it becomes easier to inhabit the area and take ownership of the site. Additionally, the removal of the previous south-western part of the former site has made for a stronger identity establishment. The area with ‘Remisen’ had a strong character prospect in itself, and as the project evolved, it only made for a bewilderment of a united identity for the whole site. A dismissal of a big part of the former site like this can be
seen as a weakness or a quality, depending on if one sees this as a lack of skills or manages to recognize ones reThrough the analysis of the site the lack of connection to it was elucidated. Thereby, it was clear as well, that to make a functioning neighborhood connectivity is a must. ment of the site plan. Both when thinking of the site in a ing essential connections, but also requiring a proposed design, whose backbone is based on a more effective infrastructural layout. There is also the aspect here of what sort of life this connectivity affords within site. The theory of affordance appears within the framework of visual perception. Psychologist J.J. Gibson formulated the correlation between objects and the perception of these, and provided an explanation of affordance. The world is not only experienced through objects, forms and three-dimensional relationships, but also through possi“The affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or ill.” The theory of affordance can be applied to several dimensions and scales. Certain environments e.g. afford differently. “ objects, tools, animals, and human displays This means that the site proposal will afford possibilities for actions and interactions. Socially engaged communities will thrive on top of the constructed, adaptable landscape stimulating senses and well-being. By manipulating the urban surface, the urban spaces and the housing units will afford different types of life to be lived inside of these. The stream will afford space for water to occupy, creating a barrier, though being rich on experience through a tour
along the stream. Bridges afford pedestrian locomotion across the barriers of water and the hydrological ribbon affords movement, activity, running, and jumping across the playful aquatic surface. A total make-over of the infrain the end, activity level. Connectivity includes the new neighbourhood in improved cohesion with Aalborg city center and affords an enhancement of this new and socially sustainable urban area. But there is a variability factor to the infrastructure, due to the connection to the partly developed areas in the proximity. This means that there is an angle of impermanence to the project’s design, which cannot be controlled. However, this challenges the proposed design’s ability to The proposed design deals with the problematic of adapting nature’s qualities to an urban setting in an extensively controlling way. There is room for the unintentional and accidental, but this within certain constraints. This is seen as the project’s solution to climate changes, however, there might not be only one solution to the changes that are at hand, but endless possibilities. The proposed site plan is an answer of how to live with water, but answers such as this exist in plentiful. The proposal stands out because of its concept, the 3 C’s; Connectivity, Community, and Coexistence with nature, which all act as generators for urban renewal within the site. As long as community thrives, and the area is connected to the city network and its context, it produces strong conditions for a sustainable neighbourhood. Nature is the third parameter, which is implemented through the moulding of the landscape, which in the end affords the framework for the overall sustainable urban living.

We connection between Eternitten and the freight rail area was found important. We worked on the infrastructure on site, and how to place and construct the paths. We worked with bicycle routes and pedestrian paths.

PHASE 2: In this phase we focused more on the shaping of the buildings and the landscape. We made a link between Øster Landgrøft and Østerå, by letting Øster Landgrøft run through the site, dividing the area into two. We used the buildings to create the landscape, by giving them an organinc form that elevated the ground in some places. We worked with an overall circular shape of the buildings that would be cut by the channel and the infrastructure. We came up with two overall programs for the buildings, two programs through the landscape we let the channel run in-between.

PHASE 3: From phase two we had one connecting shape. In phase 3 we tried to break up this shape and create smaller communities. To break up this shape we put in attractor To create a hierachy, the built mass would become more concentrated near the points. The buildings became more independant, but put together in smaller communities. We worked on creating a center where the the programs would meet in a structure.

PHASE 4: In phase 5 we tried to focus more on the cluster houses. the blocks around them. The cluster houses were placed on a curved line through the entire site, creating small communities. The apartment blocks were moved into the site, creating useful spaces on both sides of the buildings. We gave the buildings an overall organic shape, to create a connection between the different typologies. We worked on the infrastructure within the site, creating an interresting loop. A hydrolical stretch was created along a part of the loop. The building in the city center received a more individual look, but still followed the overall language of form.
