The Barker Challenge:Build More Homes

• Need for massive increase: 200k/yr > 240k/yr > ?400k/yr?

• Will need brownfield + greenfield

• “Political” attack by shires – “unholy alliance” with cities

• The architects’ crusade: “Barcelonise” our cities

Source: Kate Barker Review 2004

240,000 homes a year: not enough?

• UK population: sharp increase: 60.6m (2006) > 71.1m (2031): +10.5m (+19.1%)

• Huge increase on last projection (+6.1m, +10.2%)

• 5.6m (53.3% total) natural increase

• 4.9m (46.7% total) net migration

• England: +19.1%

Good and Bad Arguments

• Bad: we must save farmland• Good: we should give people choice of access to

public transport, shops, schools• By public transport as well as car• So: concentrate growth around transport

interchanges• And: raise densities there (“pyramids of density”)

UK: A barely developed countryside…

• UK: 14.3% developed; England: 19.1%

• These are overestimates:

• England: 10.6% 1991

• 1996-8: ca 8,000 hectares/year developed (=Runnymede)

Land Lying Idle…

• EU Set-Aside: June 2004, 476,000 hectares, almost 5.0% of England

• Greater SE: 100,270 hectares, 8.6% • Essex 10.7%• Hampshire 9.1%• Oxfordshire 11.4%• Bedfordshire 11.6%• Far in excess of most generous estimates of land

needed for housing!

Empty Land, Empty Homes

• Land banks: Are volume builders hoarding?• Buy-to-leave: 670,000 empty homes, 300,000

long-term• Joey Gardiner (R&R, 31 August): Central Leeds:

20% empty• Similar stories: Manchester, Salford, Birmingham,

Hull, London• Manchester: up to 40% (Ron Hack, Ecotec)• London: 70% bought off-plan

Future of the typical English town?

House prices/earnings 1999, 2006

What do people want?Earlier survey evidence

• Home Alone (Hooper et al 1998): only 10% want a flat; 33% won’t consider a flat

• CPRE (Champion et al 1998): people want to live in/near country

• Hedges and Clemens (q. Breheny 1997): city dwellers least satisfied

• Conclusion: we hate cities!

What do people want?MORI for CABE, 2005

• Over half the population want to live in a detached house

• 22% prefer a bungalow• 14% a semi-detached house• 7% a terraced house • Detached house most popular choice, regardless

of social status or ethnicity• Period properties (Edwardian, Victorian,

Georgian) most desirable overall: 37%

New Households, New Homes• 80% one-person• But only about one-third “single never married”• Will demand more space per household:

Separate kitchens/bathrooms/loos, Spare rooms, Work spaces

• Land saving reduces as densities increase:• 30 dw/ha yields 60% of all potential gains, 40

dw/ha 70 per cent• So biggest gains from minimising development

below 20 dw/h, not increasing 40 dw/ha+• So: go for 30-40 dw/ha with variations: higher

close to transport services (Stockholm 1952!)• But won’t achieve same person densities as

before!

Density Gradient (Rudlin+Falk)

Lessons from Land Use• Public Transport needs

minimum density:• Bus: 25 dw/ha• LRT: 60 dw/ha• Exceed recent densities• Big gain from 30-35 dw/ha• Plus “pyramids” up to 60

dw/ha round rail stations• Urban Task Force• Traditional – Stockholm,

1952!• Or Edwardian suburbs!

Planning in Britain:A Verdict (1)

• Andrew Gilg: Planning in Britain: Understanding and Evaluating the Post-War System (London: Sage 2005)

Where Are We Now?Gilg’s Verdict

• Middle-class bias• Not always democratic• Balances economic growth, conservation: a

dilemma• Increasingly market-driven• No obvious alternative

Where Are We Now?Gilg’s Verdict

• Big Achievement: urban containment; preservation of countryside

• Big Failure: development not sustainable: work, homes separate

• Another Failure: transport not integrated; transport system overloaded

• Need: integrated development; New Towns• Compare: Containment of Urban England (1973)!

Making it happen:The 2004/2008 Acts

• Radical change – biggest for 35 years• Working through at regional strategic level• Planning Gain Supplement > Tariffs• Can it solve the “infrastructure deficit”?• The major issue in solving the housing crisis!• But also: the NIMBY factor – will get worse?• 2008: RSSs to RDAs

Where Are We Now?A 3-Pronged National Spatial Strategy

• 3 key needs:• “Grow SEE”: Better connections on

Sustainable Community Growth Corridors• “Shrinking the N-S Gap”: Bring North,

Midland Core Cities/City Regions closer to London

• “Grow City Regions” around Core Cities

South East England:Global Mega-City-Region

Urban Clusters (Hall+Ward 1998)

Sustainable Communities Corridors:Growing the SE into the Midlands…

Green Belt – or Green Blanket?

The Infrastructure Gap:Roger Tym Report

Planning Gain Supplement v. Tariffs

• Planning Gain Supplement: a national development land tax) on development gains

• Tariffs: similar, but levied by LPAs/vary LPA/LPA• Related to infrastructure costs of Local Development

Plan• “Section 106” retained: MK, Bedford…• Local versus regional investment: ‘local gain’ for ‘local

pain’ • But problem of regional infrastructure: New rail

connections; national motorway junctions (Article 14: A2, £92 million)

The North: Managed Decline?• The great Pathfinder row• How much to keep? How

much to demolish?• Are incentives perverse?• YES: SAVE Britain’s

Heritage• NO: ODPM• Family-Friendly Housing in

Cities• How much Greenfield?• Issues: VAT, Infrastructure

(Manchester, Leeds, Liverpool)

The Challenge

• Deliver the houses• Defend a “balanced portfolio”: Brown/Greenfield• Build sustainable suburbs• But: can be “New Towns” too (seldom just that)• Sustainable urban places – linked along transport

corridors• Fund the infrastructure/ Coordinate development,

transport• Countryside – for people!• A big challenge: equal to 1950s, 1960s• They did it – so can we!
