An urban answer to the misfortunes of dispersed, fragmented, uncontrolled and alienating suburbia. 


ABSTRACT

Suburbia in the UK is experiencing turbulent transformations. From being an idyllic habitation for homogenous, relatively affluent middle class, it has become a complex reflection of political, social and economic processes in the urban cores – gentrification, a property bubble and housing shortage. As a result, more and more households are being expelled out from the inner areas into suburbs and then, further out to the fringes. In the face of the increasing influx of population and scarcity of land, project proposes a linear suburbanisation - a concentrated, medium-density but high-intensity development which uses the land effectively and creates diverse built environment alongside the infrastructure. By exploiting the most basic urban elements and typologies such as street, perimeter block and courtyard building, and placing them in a dialogue with a natural setting, a new type of suburbia emerges.



URBAN AND SOCIAL CONTEXT 

• UK LAND USE. 7 % of UK area is urban (including infrastructure), 70 % is farmland.(1)
• WHAT THE URBAN AREAS ARE MADE OF? Only 2 % of urban areas are buildings. 54 % is green space (gardens, parks, etc.).(2)
• UK POPULATION. 64 million. 83 % of the UK population live in cities.(3)
• SUBURBAN LIFESTYLE. 15 % of city population live in an inner city, while 85 % live in outer suburbs.
• THE AGE OF LONELINESS. 29 % of the UK population live alone. 1 million older people live alone.(4)
• LOVE OF GARDENING. 90 % have a garden (including communal).(5)
• WORK AT HOME. From 30 million workers 4 million work from home.(6)
• AUTOMOBILE DEPENDENCY. 36% of the UK population commute to work by car. The average UK commute is 54 minutes.(7)
• UK’S HOUSING CRISIS. UK housing shortage is almost 1 million homes.(8)

INNER CITY / OUTER SUBURBIA



The project draws a mental framework to the set of spatial, social and environmental issues of outer suburbia and its relationship with the inner city (9):
• Rising and ageing population,
• Housing shortage,
• Increasing poverty and precariousness,
• Social isolation and reduced connectivity,
• Economic, cultural and ethnic segregation,
• Car dependency, poor public transport, increasing road traffic congestion,
• Land-consuming, sprawling development and controversial green belts.

GREEN BELTS

Unwillingness to build high and densely, inability to accommodate empty homes, complexities of brownfield redevelopment and scarcity of land have led to a development of ever increasing expanding of UK cities. However, Green belts designated to limit urban sprawl are now the challenge for both the politicians and developers. 



Green Belts around the British cities are designated for:
• making a distinction between rural and urban,

• preventing from urban sprawl and conurbation,
• providing access to open green space.

CASE STUDY: LONDON


London's Metropolitan Green Belt policy has several significant drawbacks. Firstly, an inefficient use of land. For instance, intensive farming (more than a third of the land (11)) on the edge of the metropolis has no significant economic or environmental benefits. Secondly, this comes at the expense of more valuable development and leads to its 'leapfrogging' and displacement beyond the Green Belt. (12) Finally, all these factors contribute to longer commuting between London and its satellites. Created with positive intentions in the 50s, Green Belt today aggravates prolonged problems of suburbia such as reduced connectivity, accessibility to services and traffic congestion. The arcadian vision of suburbia must be reviewed.

The project proposes infrastructure integrated development within preserved yet transformed Green Belt.

THE CONCEPT - A LINEAR DEVELOPMENT

Suburban condenser defines a clear edge between Nature and build environment. At the same time, by being porous, it allows the Nature flow through.

THE COMPONENTS

SC uses infrastructure as a form-defining armature which supports chain-link enclaves and is perforated with heterotopic voids. (13)


Basic module exploits the traditional, normative 600ft pedestrian armature between centres.(14)


A city is a plane of tarmac with some red hot spots of urban intensity.

Axonometric view


Infrastructure has a clear functional, scale and speed hierarchy. As such it does not have a segregating effect on communities. 
Infrastructure is an integral part of the formation and its footprint ratio to entire development is minimised.





Heterotopic voids provide a space for uncertainty, endless possibilities and transformations for the future development. They are landmarks and nodes within the continuous framework.



Heterotopic void. Nature: park / forest / meadow



Heterotopic void. Intensification: housing infill



Heterotopic void. Industry / service / retail: sheds, warehouses, shopping centre

Heterotopic void. Football field: games, concerts, events


Enclave / neighbourhood.
The enclave is a self-organising system which accommodates the private sphere - housing, business and retail activities, incorporate communal life and embraces the public sphere. By using uniformity and repetition, equality is ensured yet it is diversified by its context and inhabitants – heterogenous and egalitarian society.



Enclave section. 

SC is a built environment where:
Public sphere is provided for knowledge and social exchange.
Co-working and work from home are supported by providing facilities next to the living space.
Different housing typologies offer accommodation for a diverse spectrum of households.
Spaces are adaptable and extendable by using flexible modules, layouts and structure.
