Rethinking Sub-urban areas: design, density and space

Rethinking sub-urban areas: design, density and space

With the Government saying we need to build 200,000 new homes a year, the RUDI/SEEDA event for Urban Design Week (17-23 September 2007) took up this theme to consider how we should be creating sustainable suburbs, and whether we need to rethink suburban housing types

See the RUDI section overview on Rethinking sub-urban areas. Here you will be able to download several reports, including Sir Richard MacCormac's Sustainable Suburbia and Nicholas Falk's Learning from New Dutch Towns.


A new report, State of the Suburbs, has been released that explores the relationship between the city and the suburbs. It suggests that the suburbs are coming off second best – despite the fact that well over three-quarters of people in the UK live in suburbs. An analysis of the issues has followed, and even a campaign to ‘save our suburbs’, in the Daily Telegraph newspaper.

The RUDI/SEEDA event drew a capacity audience to the Mercedes Benz centre, located appropriately in the leafy Surrey suburbs around Weybridge. The town is home to some of the innovative Span developments fof the 50s and 60s: ahead of their time in design, could they even provide a model for the future? Three presenters made some very interesting points.

Bringing design quality to the suburbs

Sir Richard MacCormac: Raising density is the way forward

Sir Richard MacCormac, author of Sustainable Suburbia: Developing a Density Toolkit, called for higher housing densities.

He posed the question: ‘Depending on definition, 80 per cent of families live in suburbia: can two sets of criteria, private and communal, be reconciled by design?’

He said the answer is yes, if housing density is raised to around 50 dph (dwellings per hectare). His key points included:
  • creating communities of 5,000 dwellings is key to supporting community facilities
  • this neighbourhoods need to have a maximum radius of 600 metres
  • everyone to be within 10 minutes' walk of everybody else
  • communities must support ‘a lifestyle which is quite different from getting into a tin-box on wheels’

He proposed three main housing typologies:

1. Courtyard housing: 57dph
2. Terraced courts: 77dph
3. Mews housing: 87 dph (suitable for city edges)

By varying the ratio of apartments to houses, ‘what took me by surprise was the higher the density of apartments, the smaller the footprint of those apartments became.'

Dr Nicholas Falk: Lessons for smarter growth

Dr Nicholas Falk, Founder Director of Urbed, recently led a study tour to report on lessons from cities in Holland and Germany. Holland has added 8 per cent to its housing stock in 10 years, and has developed many successful new suburbs. But why, in Britain, do people feel suburbs aren’t as good as they used to be? Why is community spirit being eroded?

Urbed has produced a toolkit, Tomorrow’s Suburbs: Tools for making London more Sustainable, downloadable from the Urbed website. Recognising the need to update many tired looking town centres, and to reduce commuting by making it easier to work closer to home, the report criticises the GLA’s complacency, and refers to the need to match the standards being achieved in Dutch and German cities.

The report’s recommendations include:

  • upgrading 100 transport interchanges
  • promoting green chains to link places together without having to use main roads
  • developing green business parks and incubators
  • setting up eco housing projects in every borough, along with measures to encourage community building.

Dr Falk said the key essentials of a successful suburb are:

  • community
  • connectivity
  • climate
  • character

He cited the example of the new town Northstowe, Cambridgeshire, for which Urbed has produced a ‘Quality Charter for Growth in Cambridgeshire’.


Stephen Proctor: Rethinking suburban housing

The third speaker, Stephen Proctor, Chair of the RIBA Housing Group and Director of Proctor and Matthews Architects, admitted that ‘housing design has been off the radar for the past 10 years'. But this is changing, as the need to design ‘good, sustainable domestic architecture becomes paramount'.

He highlighted several case studies where new approaches were being taken to sustainable suburban developments.

March, Cambridgeshire, (viewable on the Proctor and Matthews website). A SmartLIFE mixed tenure residential development currently under construction in two Fenland towns. SmartLIFE is a sustainable growth project currently operating in the UK, Sweden and Germany. BRE will be monitoring a range of Modern Methods of Construction (MMC) in this development.

Houghton Regis, Bedfordshire
This project on the edge of Luton won Proctor and Matthews the international RIBA competition in December 2006.
200 homes, 70 dph, range of dwelling types, mews courts, shared surface treatment. See also South Beds council website.

Dale Mill, Rochdale (slides and images in pdf format)
Proctor and Matthews were awarded a 2007 Housing Design Award for this Pathfinder scheme. The first application for a ‘rash of semi-detached boxes’ was refused. Site lies 1.3k from Rochdale, and is home to an Asian community. Family units of interconnected dwellings with up to 7 bedrooms (4+3, or 5+2).

Greenwich Millennium Village (slides and images in pdf format)
Greenwich Millennium Village (67dph) was the first Millennium Community to be identified, and is located at the southern end of English Partnerships’ 121 ha (300 acre) Greenwich Peninsula site. Shared surface streets at front.

Abode project at Newhall (slides and images in pdf format)
Stephen Proctor said this project was a good example of how the Government’s housing policy statement PPS 3 could be followed. The Mews clusters, designed by Proctor and Matthews, have the ‘wow’ factor.

Stephen said that Proctor and Matthews were interested in developing the concept of the unit, a house that can be delivered on the back of the lorry. See Proctor and Matthews website for more details.

He said one inspiration is the 1950s and 60s Span developments of Eric Lyons, an early pioneer of higher density and greener development. Span ultimately built over 2,100 homes, mainly two and three bedroom houses and apartments, in London and the South East: notably in Ham, Blackheath, Weybridge, Ashtead, London SW19, West Byfleet and New Ash Green.

Lyons aim was to provide affordable well designed family housing situated in a landscaped environment that fostered the idea community living. Together with fellow architect Geoffrey Townsend, and landscape architects Ivor Cunningham and Michael Brown, Eric Lyons created a set of houses that introduced European Modernism to the British market.


The debate: Panel discussion and questions from the floor

Ben Kochan, consultant, and author of Achieving a Suburban Renaissance, published by the Town and Country Planning Association in September 2007, and Pat Tempany, Head of Urban Renaissance and Housing at SEEDA joined the panel, for a debate chaired by RUDI chairman Peter Stoneham.


Q: What needs to be done to improve the quality of design of new developments?

Stephen: ‘Housebuilders produce the mediocre, it’s easy to fall back on what they know. There is a great cynicism in housebuilding.’

Pat: ‘Local authorities need to develop a real vision for their places. At the moment, we end with lots of individual sites that incrementally make up places. There is a lack of communication, developers and councillors do not talk to each other.’

Ben: ‘We need a suburban task force, we don’t really have any policies for our suburbs. For example, do we need a density maximum?’

Peter: ‘Developers tell us their margins are tight. But we are never given any real numbers. We need hard figures.’

Nicholas: ‘There is a ridiculous bidding up of land values, we need to get the price right. Also, two thirds of the infrastructure costs comes from the public sector. We need to create a mechanism for collecting money from the developers to pay, instead of people moving in, and finding there’s no school.’

Q: One reason for the success of suburbs is their adaptability. How do we plan for this in the long term?

Stephen: ‘We have a rose-tinted view of suburbia, I’m not sure if it is a good model for the future. There are so many wasted front gardens: we can rethink that. I think we have to be more imaginative with our housing stock.’

Ben: ‘There are problems with environmental performance – most suburbs are low performing.’


Q There has been little mention of other activities, for example providing for small businesses such as hairdressing.

Sir Richard: ‘I agree. We need to look at commuting patterns, and what the economic life of suburbia might be.’

He warned of the problem of the development of ‘edge cities’ in the USA consisting of ‘endless shopping malls’.

Nicholas: ‘Some of the most distinctive places in Britain are peripheral estates. We need to find new models – the concept of ‘wired up’ communities with people sitting in front of computers depresses me.’

Ben: ‘Independent work spaces are needed. I like Wayne Hemmingway’s idea of an Enterprise Centre with a coffee bar.’


Q: What are the elements of suburbia we should seek to preserve?

Sir Richard: ‘The concept has to be evolutionary. The image of the equivalent to a tiny little stately home should be fading away. If you don’t have front gardens you can have bigger back gardens or village greens.’


Q: How can we persuade people to use their local facilities?

Nicholas: ‘The trick is to grow new developments onto existing communities. I am astonished at the waste of land around stations, for example. Our declining railway stations should be at the heart of new development.

Peter: ‘Do we want to bump into people, or remain anonymous?’

Sir Richard: ‘Brick Lane is a virtual community, people meet pottering in and out of their front doors. There’s a sense of community.’
