INTRODUCTION. This directory intends to set out both the proposal and influencing context for a hypothetical design project which responds to research undertaken within my design thesis. Current redevelopment practices employed across the city can be regarded as a significant contributor to the prevalence of loneliness, affecting most predominantly young adults, who are frequently displaced. Recognising this relationship and the accompanying narrative, this project proposes an alternative redevelopment strategy, in response to the specific conditions of a site in Poplar, Tower Hamlets. Not seen as a solution to loneliness or gentrification, but rather facilitating the opportunity for an alternative narrative.

INTRODUCTION. LONELINESS

Loneliness has received increased proliferation throughout the media and public opinion over the past two years attributed greatly to the BBC’s ‘Loneliness Experiment’, which identified the rather unsettling prevalence currently experienced across the UK, and particularly by young adults (BBC, 2018). Leading to the Government appointing the first-ever Minister for Loneliness in October 2018, whilst publishing their ‘Loneliness Strategy’, which identifies, alongside other contributors; transport, access to community space, neighbourhood design and housing (GOV, 2018), advocating for more research to better understand their potential impact. The theoretical research accompanying this design project has attempted to explore the potential relationship between residential architecture and contemporary urban loneliness. Employing a site within Tower Hamlets - referred to as West Poplar -which has provided an opportunity to understand the potential socio-spatial contributors of the residential environment. The project takes a particular focus on young adults, identified as the worst affected demographic in the UK. Contributors to loneliness can be understood as producing a discrepancy between an individuals desired and actual social relations. Defined within the literature as ‘predisposing factors’ and ‘precipitating events’, which can influence an individual’s expectation and desire for social relations or restrict access and the formation of actual social relations (Perlman and Peplau, 1984, p23). Predisposing factors include personal characteristics, situational determinants and cultural values and norms which make people vulnerable to loneliness - whilst precipitating events can be understood as transitions or changes in an individual’s socialising patterns that trigger loneliness.

INTRODUCTION. LONELINESS

Following this model an understanding of the possible relationship between loneliness and the built environment has received growing interest from external organisations and professionals associated with the built environment, recognising its potential to inform future design. These include architectural practices, residential developers, built-environment consultants, Universities and Design Think Tanks (DTT). I have been working in collaboration with ‘The Loneliness Lab’ a DTT, which has brought together academics, professionals and policy-makers to try and re-imagine the spaces within the city and how they may influence loneliness. The Lab is partially funded by the multinational residential developer Lendlease, whose invested interest further highlights the growing importance of this topic, and who have the potential to influence the way planners, builders and architects create spaces. Our work at the LAb is currently informing the Governmnet’s latest loneliness strategy.

Governments’ Loneliness Strategy.

Whilst working with the Lab, we were commissioned to produce a literature review, combined with group discussions, specifically identifying contributors to loneliness for young adults.

The built environment was only identified directly in a few cases and predominately associated with social isolation like; single occupancy, privatisation of public space, declining social infrastructure, accessibility and working habits. However, also indirectly associated with contributors like; high population turnover, housing tenure, transitions, regeneration, poverty, increasing housing costs The built environment contributors identified within both my theoretical research and collaboration with the Loneliness Lab can be regarded as both situational determinants and precipitating events, as shown.

INTRODUCTION. LONELINESS

With respect to the specific context of Tower Hamlets I found that it was primarily the contributors associated with both the ‘Process’ and ‘Characteristics’ of residential redevelopment that potentially had the greatest influence upon the prevalence of loneliness for young adults. Discussion with existing residents and young adults who had previously lived in the area reaffirmed the relevancy of these contributors.

The table on the opposing side identifies characteristics which have been discussed or studied within the literature with respect to influencing social relations or behaviour. As you can see the majority has focused on the neighbourhood and street, with more recently studies on co-housing.

INTRODUCTION. SITE

BOROUGH - TOWER HAMLETS

WARD - POPLAR

The site is located within the London Borough of Tower Hamlets, one of 12 inner London Boroughs, positioned on the North bank of the River Thames. This central London location means land for new housing development is scarce which has led to the frequent and highly contentious redevelopment of existing council estates.

Poplar is a Ward within the London Borough of Tower Hamlets located between Lansbury to the North and Canary Wharf to the South. In recent years it has seen the approval of multiple large-scale redevelopment projects typical of the characteristics and process identified previously.

INTRODUCTION. PROPOSAL

Proposed Alternative The proposal is envisioned as an alternative to a hypothetical narrative involving the typical redevelopment of West Poplar through the wholesale demolition of the existing homes. Responding to the concerns identified with the current process and accompanying characteristics of residential redevelopment within Poplar and surrounding Wards. Acknowledging current development as both a potential predisposing factor and precipitating event contributing to the prevalence of loneliness for young adults. Instead this project will highlight the opportunities for augmenting the existing residential environment with additional housing through an integrative development process, acknowledging Londonâ&#x20AC;&#x2122;s crucial need for additional homes whilst attempting to maintain and increase the diversity of the existing environment.

“The fastest growing population in the UK” Tower Hamlets has seen the fastest population increase out of all 391 local authorities in the UK, with a 37 per cent change over 10 years (2007-2017). The population is predicted to reach 365,000 by 2027, equivalent to 15 new residents every day (TH, 2018). This growth is closely linked to the large volume of new housing being constructed in the Borough. Whilst the population of the Borough is significantly increasing as a whole, the Ward of Poplar has began to see a reduction in growth. Although expected to increase with the completion of the Blackwall Reach development, in 2022.

Like many of the surrounding Wards Poplar is predicted a large growth in population over the next 10 years. The growth however is only expected in the Eastern half of the Ward, while the Western portion is expected to remain relatively unchanged. This predicted growth will mean the population density of West Poplar will be significantly lower than East Poplar and surrounding Wards. Tower Hamlets currently has the 2nd highest population density in the UK, behind Islington (TH, 2018).

“Highest proportion of residents aged 21-28” From the chart you can see that Tower Hamlets has the highest proportion of residents between the ages of 21-28 years, and lowest proportion of residents over the age of 40 years. The Borough has a median age of 31 years, making it 4th youngest local authority in the UK (TH, 2018). Almost half of the Borough’s population are between the ages of 20-39 providing a particularly appropriate context for this project. The Borough’s young age profile is a reflection of the large amount of young professionals moving to the area for work, along with elderly residents and families forced to move away due to increasing housing costs (Future of London 2018).

Young residents typically have shorter occupancies, with 77% of the residents who moved out of Tower Hamlets within 5 years aged between 18 and 34 years. As a result the Borough has a relatively high population turnover rate of 23% compared with the London average of 9%, although only 11th highest in the UK. A high population turnover reduces the time residents have to form an attachment to place and social relations within the home environment, therefore potentially encouraging the prevalence of loneliness. Last year 36,000 people moved into the Borough with 29,900 moving out.

Tower Hamlets is an area of extremes with the highest levels of income inequality in the UK (Tower Hamlets, 2016), as demonstrated by the Wards of Poplar and Canary Wharf. Comprised of predominately the richest and poorest residents in Tower Hamlets, the Wards present two almost completely segregated and polarised communities. This socioeconomic disparity is as evident physically on the urban landscape, with transport infrastructure creating a rather inaccessible boundary, as it is culturally and psychologically amongst the residents (Fraser, 2018).

CONTEXT. SOCIO-POLITICAL

The current socio-political concerns surrounding largescale redevelopment projects across London would act as a considerable barrier to many redevelopment projects. Terms like ‘regeneration’ and ‘redevelopment’ have become synonymous with gentrification and even social cleansing, and navigating these concerns would be fundamental to gaining the support of both local residents and the wider London community. Whilst acknowledging the this projects position within the wider socio-political debate surrounding gentrification, it must not be employed as a solution, instead emphasising how the unconventional development strategy and specific spatial opportunities of the site may mitigate some of the socio-political concerns attributed to neighbouring redevelopment projects. Current redevelopment projects in Tower Hamlets like Chrisp Street Market (CSM) and Blackwall Reach (Robin Hood Gardens) have recently received fierce opposition from residents as well as campaigning from the wider London community, resulting in delays and even plans being put on hold, in the case of CSM25. It will, therefore, be imperative to the success of the project that existing residents and stakeholders are able to differentiate between the standard development process commonly employed, and the non-destructive and integrative method proposed. Disassociating from the negative reputation and socio-political concerns surrounding contemporary large-scale redevelopment. A close relationship between the Design Team and the Poplar Neighbourhood Planning Forum (PNPF), will provide residents with a familiar means of voicing any needs and concerns, whilst ensuring a succinct understanding of the project from an early stage.

The completion of the Elisabeth Line (Crossrail) and opening of Canary Wharf Station in 2021, combined with the â&#x20AC;&#x2DC;Poplar Linkâ&#x20AC;&#x2122; as part of the North Quay Project, have resulted in a significant increase in the predicted PTAL across the site (TfL, 2018). This will have a considerable impact on future development, with increased PTAL encouraging higher housing densities. Future development on could therefore expect a recommended housing density of around 170 - 200dph, more than double the existing average.

CONTEXT. HOUSING EXISTING RESIDENTIAL TYPOLOGIES MAISONETTE BLOCK The maisonette block is extremely common across Poplar and the surrounding wards occurring in various forms typically with a flat roof condition. This typology features both ground access individual entrances and shared gallery access corridors, giving residents a high degree of visibility and observational connection. The homes are split over two levels, while the blocks are usually arranged facing inwards with a stepped back relationship from the street.

Construction year : 1956 Dwellings per block : 10 - 20

CONTEXT. HOUSING

NEO-GEORGIAN BLOCK The Will Crooks Estate was constructed before the war as part of the Sophia Street Slum Clearance scheme. It is made up of 5 Neo-Georgian gallery access blocks all 5 storeys in height as shown in the elevation. Again this typology affords a high level of visibility from both the street level and the balconies looking down, with the orientation of the blocks allowing residents to observe each other. The blocks share both a playpark area central to the estate, in addition to rear communal gardens which are overlooked by the bedrooms and lounges of the blocks.

Construction year : 1935 Dwellings per block : 15 - 35

CONTEXT. HOUSING

TENEMENT BLOCK The tenement block of flats is also a common typology across Poplar, with many constructed after the war to house the residents displaced through bomb damage. Another of the flat roof typologies which give West Poplar a distinctive architectural language. These blocks are commonly arranged facing away from the main street and share communal gardens to the rear, made up of 1 bed flats. The blocks have a similar access system to the maisonette typology.

Construction year : 1973 Dwellings per block : 15 - 18

CONTEXT. HOUSING

TERRACE HOUSES These typical modern terraces are fairly universal in characteristics and include individual driveways, creating a very suburban environment within the middle of the city. Each home has individual entrance and back garden and faces the street, arranged in parallel blocks. These homes have the lowest housing density all of the West Poplar typologies. Construction year : 1996 Dwellings per block : 1

CONTEXT. HOUSING

MALAM GARDENS TERRACE HOUSES Another low-rise low density typology, the Malam Garden terraces each have individual entrances which are mirrored, giving a coupled entrance condition. The homes face onto the street with a small walled garden to the front creating a semiprivate space for belongings and the bin. The homes are arranged in parallel blocks similar to the modern terraces. Construction year : 1936 Dwellings per block : 1

CONTEXT. HOUSING

FLAT ROOF TERRACE The final of the residential typolgies in West Poplar is the flat roof (townhouse) terraces. Built at the same time as the tenement style blocks, these homes consist of coupled individual entrances along with garages. Ranging from two to three storeys, the blocks are commonly arranged around central parking areas and stepped away from the main street. The homes also have individual private gardens to the rear.

This map identifies all of the residential developments across Poplar and the surrounding wards since the announcement of Crossrail in 2007. As shown there are multiple submitted and proposed developments surrounding the site, reacting to the increased predicted PTAL scores and land values.

CONTEXT. HOUSING TYPICAL CONSTRUCTION -

The post-war flat roof terrace typology is most prevalent across the proposal site. Constructed through load bearing block masonry walls with an outer brick leaf, creating a cavity wall. Wooden floor beams are then supported by the walls and built into the block-work or fixed with a hanger. This common form of construction means the homes are easily adaptable with extensions and renovations.

CONTEXT. HOUSING EXTERNAL INHABITATION -

The space outside the entrance to the tenement blocks is divided from the pavement by a narrow flower bed creating a perceived boundary. Residents frequently inhabit this space with belongings as shown in the image.

The narrow space created by a simple barrier added to the tenement blocks gives the occupants a greater sense of ownership, encouraging external inhabitation. As shown in this image some residents take full advantage of this means of expressing identity or character.

CONTEXT. HOUSING

This sense of ownership over external space is even present on the balcony walkways on the floors above with residents hanging washing and storing belongings permanently within these spaces. The balconies are shared between only 2 - 3 residents creating a rather semi-private space.

The ground floor of the Will Crooks Estate blocks are raised three steps from the pavement creating a symbolic threshold between the privacy of the entrance space and road. The residents frequently leave belongings within this space, with an apparent sense of security as shown in the photo.

In this instance just one step still creates a perceived threshold outside of the home, giving the resident a boundary they feel comfortable inhabiting and taking ownership over. The bin store wall also creates an almost enclave affording a greater sense of privacy.

CONTEXT. HOUSING

The small step back within the entrances of the townhouses gives residents an area to inhabit outside of the home, partially protected from the elements. As shown this space is useful for storing bins as well as pot plants, giving each identical entrance condition the opportunity to be unique.

The brick wall and podiums give each home a defined boundary, creating a space in which residents feel comfortable inhabiting. As shown some residents have even constructed structures to extend the use of this space, extending the private boundary of the home into the public realm.

FLAT-ROOF TYPOLOGIES

WEST

The Eastern portion of Tower Hamlets is made up of an abundance of typically post-war flat roof residential typologies, usually between 2 and 5 storeys. Research was recently conducted which estimated that 40,000 new homes could be constructed through rooftop and airspace development across London, providing a significant amount of new homes. (HTA, 2016; Knight Frank, 2017). Highlighting the potential of vertically extending existing homes across West Poplar to provide the recommended housing densities.

CONTEXT. MORPHOLOGY

1920’s By the 1920’s the area of West Poplar had development into predominately back to back terrace housing, with a dense urban grain and well defined street edges, as shown. An urban condition replicated across the surrounding docklands area.

1950’s Following bomb damage from the II World War and extensive slum clearance the residential environment had completely changed, with most of the back to back

terraces destroyed. The housing was replaced with higher density blocks or temporary prefab housing. As shown, these typologies had a different relationship with the street creating a less dense urban grain.

1980’s Eventually all of the pre-war terraced housing and temporary blocks were removed and replaced with higher density maisonette blocks, flats and new terraces. The new housing was typically orientated away from the street and shared a stepped back relationship, following the postwar planning rhetoric at the time, which intended to create a separation between the car and living environments.

2020 Recent additions to the residential environment have included two-storey terraced housing to the south, giving the area a distinctively low housing density, while maintaining the stepped back relationship with the street through the provision of driveways and on-street parking.

CONTEXT. MORPHOLOGY CHANGING MORPHOLOGY -

Sophia and Rook Street

Will Crooks Estate

Typical examples of the back to back terraced conditions replicated ubiquitously across Poplar. The streets were recorded with extreme deprivation and regarded as slum conditions.

Both streets were later demolished as part of the Sophia Street Clearance scheme by the LCC in 1935, along with 200 dwellings. The replacement housing - The Will Crooks Estate - employed the LCC’s High density gallery access blocks.

During the 1920’s what is now known as Saltwell Street was named Lower North Street, and comprised of predominately terraced Housing and shops.

Saltwell Street received considerable bomb damage leading to the complete removal of the existing housing. Temporary Prefab homes were constructed in replacement to house the displaced residents.

In the 1970’s Saltwell Street was redeveloped with the construction of Maisonette and Tenement style flats which remain today. fig. 5

CONTEXT. MORPHOLOGY ARRANGEMENT HALE STREET & WADE’S PLACE

SALTWELL STREET

The Will Crooks Estate located between both Hale street and Wade’s Place also shares a stepped back relationship with the street, forming pockets of greenery and widened pavement areas creating a divide between the street and housing.

The housing along Saltwell Street shares a stepped back relationship with the street, again creating a large separation. The nature of these inbetween spaces results in almost redundant space which is seldom used.

Through identifying the orientation of each residential block, as shown in orange, it is possible to highlight the inverted relationship the housing shares with the road. Almost all of the blocks are orientated with their entrances facing away from the road, usually with their back or garden condition instead facing.

It is possible to group the blocks into clusters which share an inverted relationship creating an almost cul de sac condition. This has helped form successful third space within the residential environment, creating a perceived changed in privacy for the residents, something obvious to visitors, especially whilst in the Will Crooks Estate.

The nature of the shared space created within the home environment can be better understood through Oscar Newmanâ&#x20AC;&#x2122;s theory of hierarchical perceived social boundaries. As shown in the diagram, suggesting that the space around the home can be divided into various boundaries with subsequent levels of intimacy and privacy afforded to residents. These boundaries depend on various characteristics :

In 2021 the Ultra Low Emission Zone (ULEZ) is set to expand, widening to become inclusive of Tower Hamlets, as shown. This is predicted to cause a significant decline in local car dependency, as petrol and diesel cars will be charged for use within the zone, leading to a reduction in parking provisions within West Poplar.

which in the context of Tower Hamlets has led to extreme levels of overcrowding (TH, 2014). Although new developments facilitate social housing they infrequently cater to this usual family dynamic.

TRANSIENT NATURE

Sense of familiarity

The population turnover for young professionals is far higher than other groups, with an average length of occupancy of just 2.3 years, expected to be even lower within London (ONS, 2018). This gives residents less time to form social relations within the home environment or an attachment to the area. Lisa remarked that she would probably stay in her current shared flat for 2 years before moving into a single bed apartment.

The presence of predominately Bangladeshi residents has established a thriving community with extremely strong social connections within the local area (Sturgis et al, 2013). Moreover, long tenancies of social rent households have encouraged high levels of familiarity, with many residents growingup and continuing to live within the area. Discussion with former resident, Wahab, a young adult who had recently moved away from his parents’ in Poplar, reaffirmed this lifestyle.

APPROACH.

APPROACH. CONCEPT

ADDITION. The concept is made up of two components. The first, the simple idea of increasing the number of homes within the site, whilst maintaining the existing. Employing both infill and extension construction methods in order to create a more diverse and intimate residential environment, pushing the limits of intrusive proximity.

FILTERING. The second component looks at the idea of filtering or controlling interactions within the proximity of the new residential environment. Employing an understanding of the spatial and material characteristics of the boundary and its influence upon a residentâ&#x20AC;&#x2122;s sense of privacy and agency.

APPROACH. BRIEF

INFILL

The project proposes developing both Saltwell street and the associated residential environment through an integrative construction process, envisioned as a pilot scheme for the potential future development of West Poplar. This unconventional process means residents will not be displaced, potentially mitigating the socio-psychological concerns surrounding current redevelopment methods. In response to the areaâ&#x20AC;&#x2122;s specific housing need the project proposes employing infill and vertical extension construction methods in order to deliver additional housing. Utilising both the existing and predicted redundant space following a decline in local car dependency along with a reduction in road widths to establish a far denser and more intimate residential condition which challenges the existing conventions surrounding intrusive proximity. Providing a diversity of social environments with the aim of encouraging a greater sense of agency and engagement within shared spaces, while simultaneously ensuring residents feel a sense of control and privacy over interactions.

EXTENSION

The new infill residential will take the form of narrow linear blocks running parallel with the existing roads, re-establishing active street conditions, while responding adaptively to the existing morphology. Additional homes will also be delivered through the vertical expansion of the existing flat-roof typologies, creating 1-2 storey extensions which facilitate both standard and reduced size 1 bed flats. Therefore enabling the site to achieve the recommended housing densities without the demolition of the existing homes.

APPROACH. BRIEF

PROPOSAL

1. Identifying all of the current and potentially usable space following a decline in local car dependency and change of use.

2. Reduction and repositioning of existing roads, combined with removal of on-street parking provision. New road width 3.5m facilitating refuse collection.

Vertical extension of existing flat roof residential blocks creating additional 1-2 storeys.

3. Applying consistent 6m offset from existing active residential frontages, taking precedent from case studies.

4. Insertion of additional residential blocks positioned to create double-loaded active street conditions along primary roads.

7. Access routes added through blocks adjoining to existing shared entrances, increasing the porosity of the residential environment.

6. Homes orientated inwards around openings to create courtyard or square conditions, acting as third space.

DISPLACEMENT OF LOCAL YOUNG ADULTS

With increasing demand for smaller flats local young adults who either choose or are forced to move out from family homes, find themselves having to move away from the Borough to find affordable housing. A lack of both affordable smaller and larger homes suited to multigenerational families significantly contributes to this situation.

A smaller 1 bed flat providing a more affordable housing option, due to its reduced spatial characteristics, is added to the top of the infill homes.

Both of these typologies will be owned by Poplar HARCA and rented at their respective market values.

APPROACH. FINANCIAL STRATEGY Primary Funding

Secondary Funding

FUNDING

GOV FUNDING

The project will be funded by Tower Hamlets Council following a similar framework to previous infill projects within the Borough. Current Infill projects led by the council, are intended to provide 100% cent affordable housing. However, as the proposal will be regarded as strategic development ( 100+ dwellings ), it will only be required to deliver a minimum of 35% affordable homes to ensure its viability.

Liveable Neighbourhoods and Corridors Fund

In terms of tenure the housing will be split into social rent ( Approx 50 family homes ), market rent ( Approx 100 larger flats ) and affordable rent ( Approx 70 smaller flats ). A majority of market and affordable rent properties will ensure finance to fund both the overall build costs and the renovation of the existing private homes. The renovation will increase the market value of the existing homes, acting as a significant financial incentive for the private owners, whose cooperation will be a fundamental component to the development. The Council will also offer to buy the homes as part of the existing Buy-Back programme.

A fund for smaller-scale transport schemes that help directly unlock the creation of new homes and jobs.

Due to the project’s implementation of objectives set out in the Government’s Loneliness Strategy, the project will be eligible for various Government funding schemes, including the DDCMS, MHCLG and the Building Connections fund (GOV, 2018, 2019). An application will also be made to TfL as the project qualifies for funding with respect to the Liveable Neighbourhoods and Corridors fund, The Mayors Air Quality Fund and TfL’s Growth Fund. In addition, local developer Canary Wharf Group will provide investment into the public realm and communal amenities following the approval of the North Quay project, as partial fulfillment of their Corporate Social Responsibility Commitment (CWG, 2019), and a section 106 agreement with Tower Hamlets council. Council already own the land and majority of the homes, significantly reducing initial costs.

MAINTENANCE FUTURE REDEVELOPMENT

APPROACH. FINANCIAL STRATEGY

SAVINGS

Due to the non-destructive development process employed there will be little demolition, besides removing outer walls and redundant street surfaces. Typical demolition costs associated with large-scale redevelopment account for a large proportion of the hard costs, which in this case are significantly reduced. Bricks from the renovated buildings can also be reused within the development again reducing the overall built cost as well as the carbon footprint from transport. Construction will occur across the development incrementally, ensuring minimal disruption to the residents. This will also reduce costs as equipment like scaffolding and cranes will only have to be hired for relatively short periods.

COST CONTROLS fig. 28

Once one of the blocks has been completed the estimated costings for future development can be adjusted appropriately taking into to account any issues with the completed construction and allowing for more accurate allowances for risks. The project cost plan will have to account for a greater construction risk estimate due to the siteâ&#x20AC;&#x2122;s location within an area of Archaeological Importance (TH, 2020) and historical relevance with respect to the II World War. The discovery of artifacts or potentially unexploded bombs could significantly delay construction, leading to increased costs. The housing market and construction industry in the UK are also in extremely uncertain times due to the COVID-19 Pandemic, expected to significantly delay or stop the majority of development. Which will make budgeting and planning extremely difficult.

Residential construction is the most common way unexploded bombs are discovered, with the Ministry for Defense disposing of about 60 every year. East London is an area of increased probability due to being a key target for German bombers during the War.

SALTWELL STREET DEVELOPMENT

The project is almost completely reliant upon the planning approval for the reduction and change of use of the existing streets. As shown by the rejection of plans in 2018 to pedestrianise Oxford Street by Westminster Council, this can be a rather contentious topic, with many local residents still relying heavily upon automotive transport. To try and overcome this impediment, it will be crucial to obtain the support of the public, existing campaigners and key authoritative figures in favour of reducing automotive transport.

In addition to the Mayor’s support, backing from the charity Living Streets, whose ongoing campaigning has resulted in the approval of the recent 2019 Oxford Street plan, heavily influencing both the Council and local residents’ opinions (LivingStreets, 2019). The influence and social media presence of the charity would be crucial in promoting the social and health benefits of the proposal to the local residents and wider community. With recent events like the #WorldCarFreeDay, further influencing resident’s opinions, and their potential approval.

MINISTER FOR LONELINESS

ROAD REDUCTION & CHANGE OF USE

Obtaining support for the project from influential and authoritative figures will be fundamental to achieving the realisation of such an unconventional proposal. Firstly, due to the project’s proposed employment as a pilot scheme (implementing the latest design theory and research regarding loneliness), obtaining support from the current Minister for Loneliness would be essential in initially progressing the project and gaining recognition from potential future parties. Through building upon objectives set out in the Government’s Loneliness Strategy and the MHCLG’s Connected Communities document, the proposal could potentially act as a case study for ongoing research. Support from the Minister of Loneliness, along with collaboration with the Loneliness Lab would act as a foundation from which the proposal can be presented to the LBTH council and Poplar HARCA.

PRECEDENT Proposing to reduce or change the use of existing public highways for residential or commercial development is not unprecedented, as demonstrated through the Snow Hill scheme by Ballymore and Birmingham Council, yet still extremely uncommon. The Civil engineer was Alan Baxter and Associates, and utilising their experience within this form of development will be crucial in achieving the successful delivery of the project.

fig. 29

The site is also partially inclusive of the St Matthias Church Conservation Area, meaning an application for consent from the Council regarding the impact of the proposal on the character and appearance of the area is required, along with a more detailed planning application (TH, 2008).

Evidence for permission would be on the grounds of technical and policy arguments in relation to reducing traffic capacity and removing on-street parking whilst enforcing one-way access.

Initial public consultation would be held informing local residents and stakeholders of the proposal’s intentions, whilst pre-application meetings would be arranged with the Tower Hamlets’ Planning, Highways, Urban Design and Conservation officers as well as the Poplar Neighbourhood Planning Forum to discuss their aspirations. A traffic assessment would be conducted by a Council officer identifying the potential impact of the proposed changes. The architect and project team would then develop the design proposal up to RIBA stage 3, holding subsequent public consultations and meetings with the Council Officers.

Predicted increased PTAL scores following the opening of the Elizabeth Line and completion of Poplar Link.

The next step would be an application to the Tower Hamlets Planning Authority, which would include planning drawings, Design and Access statement, Transport Assessment, Heritage Statement and a Statement of Community Engagement, summarising consultation work. APPROACH

The application would request:

Initially, the Project Team would conduct a feasibility study, inclusive of a ‘right to light’ survey due to the proposed infill strategy. This would determine the potential for development whilst identifying any existing constraints at an early stage which may inform the design. Surveys by utility companies would be contacted obtaining quotes for any necessary diversions, in addition to a tree survey identifying any Tree Preservation Orders and highlighting any restrictions to potential development, particularly relevant to Hale Street.

The reduction of road widths across the designated West Poplar site, excluding Poplar High Street. The change of vehicular access on Saltwell Street to one-way. The change of use for land acquired following reductions, to Class C3. The development of residential blocks providing 200+ dwellings.

Supporting evidence would include:

The extension of the ULEZ in 2021, significantly reducing local car use. The Mayor’s Transport strategies promoting walkability, public transport and reducing pollution. LBTH Local Plan objectives for reducing car use. In this Instance, the public highways are adopted by the Tower Hamlets Council, who take responsibility for their management, maintenance and risk (Highway Maintained at Public Expense). The freehold for the underlying land is also owned by Tower Hamlets Council meaning that only single landownership consent would be required for the infill component of the development. The vertical extension and renovation of the existing homes, however, would require the consent of the private property owners before development could progress. An application could be made by the Council and Project Team to the Tower Hamlets Planning Authority for the Infill development with either later amendments following the consent of private owners or a secondary application at a later stage. Following consent from Tower Hamlets planning authority, the project team would progress to RIBA stage 4. The Architect would then produce Tender Drawings for the contractors. While application would be made for a ‘stopping up order’ to remove the existing highway obligations (vehicular access and on-street parking), but only after any utility diversions

have been carried out. A section 278 agreement with the Council would enable the proposed alterations to the public highways, whilst changes to traffic management orders would have to be agreed, along with statutory public consultation informing affected parties of the intended changes. Following the approval of all by Council, the development would then to progress to RIBA stage 5 and construction could begin.

DELIVERY. STRUCTURAL STRATEGY PRIMARY COMPONENT

The structural strategy is reliant upon primary glulam columns which are spaced 4m apart. The columns are designed in a coupled arrangement which provides increased stability without having to increase the width of the cross section. This structural component is needed due to both the restricted width of the infill blocks and the proposed storey heights ( recommenced above 2 storeys). An example of this component in use is the Whistler Public Library in Canada by HCMA architects, which at 4 storeys high makes use of relatively narrow coupled external glulam columns as shown.

Primary roof beam rests between the coupled columns fitting within specified cutouts in each column, therefore sharing the load.

Perpendicular beams are as supported through similar method of cutouts within the columns.

Both columns are connect onto steel flitch ground plates which are fixed in place with blots. Columns are raised 200mm above the ground outside of the water splash zone

Steel flitch plates are connected to concrete foundations through steel anchor bars cast into the concrete.

Load bearing masonry walls are constructed between every second frame acting as the party wall. This also provides increased stability to the structure by preventing racking, functioning like shear walls.

Stage 2 Primary glulam columns craned into position and fixed to steel flitch plates, with temporary supports attached until beams connected. Columns transfer building load to foundations vertically.

Stage 5 Secondary floor and roof beams are connected to the primary beams through metal hangers. These smaller beams tranfer loads across to the primary components.

Stage 6

Glulam Beams craned into position and connected through steel flitch plates and blots. Beams act to transfer horizontal loads to primary Columns, while giving the portal frame structure stability.

Plywood sheathing is added to the roof and floors creating a flat surface for finishings. The board is orientated with the grain perpendicular to the primary beams creating an opposing force to racking, with the boards acting in tension.

The home deals with a difficult narrow site alongside

a raised nosiy bypass. The design therefore prevents the intrusion of privacy from the nearby bypass, through the absence of parallel facing windows. Instead the home employs a stepped facade with perpendicular windows allowing plenty of daylight, while restricting both noise from the street and observations. This design would also work effectively alongside another home of similar characteristics allowing for greater proximity.

TECHNICAL FOCUS. PROPOSAL

THE EXTENSION OF THE TERRACED HOMES My research looked at the relationship between loneliness and the residential environment. Identifying the process of redevelopment as a significant potential contributor within the context of Tower Hamlets. In response the project proposes delivering additional housing through an integrative development process, employing both infill and extension construction methods.

The technical focus is on methods of structural extension as a means of providing additional housing, and how this addition may change the nature of the social boundary of the home.

The possibility of utilising local contractors is also a key consideration, acknowledging the severe level of unemployment and absence of intermediate skilled work within the Borough.

TYPICAL DOMESTIC EXTENSION MASONRY OR TIMBER CONSTRUCTION.

Lightweight timber loft conversion, extending the roof to facilitate addition floor space. Vertical extension relies on the existing structure. Rear or side extension of existing masonry home, typically increases the size rather than creating additional home. Both can be carried out by local contractors with locally sourced materials like reclaimed bricks.

This method of extension relies on the existing structural capacity of the home in the case of vertical extension, or is restricted to end conditions as a way of actually providing additional homes.

Bricks arranged to create structural fin which supports beams spanning the large hall removing the need for internal columns. The Fin can also accommodate services like drainage as shown. Construction is not specialised so could be carried out by local contractors.

The structural fins could support additional loads allowing for the vertical extension of the homes. The Deep nature of the fins also creates a semi-private space. The construction time is longer compared with steel or timber columns would be considerably longer.

VERTICAL EXTENSION STRUCTURAL STEEL TABLE GOLDERS GREEN ESTATE - RCK ARCHITECTS

Rooftop extension of existing 1970â&#x20AC;&#x2122;s residential blocks, proposing steel table system to support lightweight CLT construction. Method means residents are not displaced during construction and the prefabricated timber can be craned into position quickly reducing overall disruption. Structure is independent of existing and would require additional foundations. Primary steel structure and prefabricated components would require specialised contractors.

This approach allows for vertical extension and addition of new homes but offers little change to the existing boundary conditions. In the example the columns are hidden behind a new brick facade.

HORIZONTAL EXTENSION INDEPENDENT STEEL STRUCTURE TOUR BOIS-LE-PRÊTRE - LACATON & VASSAL

Independent steel structure and concrete floors added to existing 1980’s concrete block, allowing for horizontal extension. Existing facade is removed and replaced with floor to ceiling height doors increasing internal daylight. Secondary sliding doors create winter garden condition which significantly improves the thermal performance of the home. The deeper boundary and secondary doors provide residents with greater control over privacy. Construction is unlikely to be carried out by local contractors.

Original Plan

Extended Plan

The structural additional completely changes the nature of the social boundary of the home, providing greater control, perhaps meaning blocks could be positioned closer. This approach didn’t actually provide additional homes but could be adapted.

HORIZONTAL EXTENSION SEMI-DEPENDENT TIMBER STRUCTURE CHILTERN HOUSE ( MESTAWOOD LSBU RESEARCH GROUP)

The research project proposes the horizontal extension of an existing concrete residential block through the addition of structural timber columns. Insulated CLT panels (SIP) are fixed to the concrete floor transferring some of the loads into the existing structure, ensuring a more efficient use of materials by reducing the structural capacity and subsequent size of the columns. Timber was selected for its environmental benefits, both in production and through sequestering carbon, with comparison to steel and concrete. The structure comprises of prefabricated components requiring specialist contractors for construction.

Assuming that the existing structure cannot support additional loads the width and depth of the timber column could be increased, creating a similar condition to the structural fin and changing the nature of the social boundary.

TECHNICAL FOCUS. APPROACH

INITIAL STRUCTURAL CONCEPT

Structural table system employed using glulam components, aligning the columns with the existing structural grid of the party walls, with beams potentially transferring loads into the existing structure, reducing the need for two columns. Stepped arrangement creating additional floor space, and deep boundary, along with removal of existing facade.

Glulam columns can be coupled to improve stability over two storeys while reducing the amount of timber used in manufacturing.
