‘to realise a plan, the effort is 50 per cent technical and 50 per cent political’
David Mackay, MBM Barcelona (quoted by Mark Pearson UDQ 113 p37)

Content
• Want to explore the future direction of Cardiff’s growth• Want to set out the scale of the housing problem and
implications for inter-generational inequity• Will argue that a half century of plans have identified the
problem and fudged the solution• Refute notion that we can export our housing to
regenerate the Valleys• Refute notion that green-field development is inherently
unsustainable• Make the case that positive planning can create a long
term sustainable solution for city and the region• Emphasise the need to create a planning process and
political consensus to underpin this

Cardiff’s dilemma part of a UK-wide crisis
• Housing supply lags behind household formation (240k pa req)• Housebuilders under-supply the market: social supply inadequate• Affordability crisis and 4.5 m wait for social housing• Many LPAs reducing housing allocations in face of NIMBYism• Social exclusion intensifying: first time buyers pay 10-12x income• Current recession
exacerbating crisis• LPAs cannot fund
infrastructure to plan ahead or reduce externalities
• National crisis: nationalcomplacency
• Nimbyism and inter-generational equity

Cardiff’s 2009 LDP: an all-brownfield ‘solution’
• 27,442 homes required: 1,750 pa • Plan saw 79% apartments, 90% on brownfield land• Effectively no 3/4 bed housing: >50% demand• 16% affordable needed: 10% anticipated (306pa)• 9,756 on waiting list now: few will ever be accommodated
‘the evidence does not support the contention that the brownfield only strategy will deliver the number of houses and the amount of employment land required. Nor will it deliver family or affordable homes or the range or type of employment land and premises (Inspector’s Letter to Council 26-2-2010 para 82)
Planners warned Councillors that plan needed suburban allocation • Inspector noted insufficient employment land• Over concentrated and problematic sites• Transport provision not plan-led• Flood risk in S &E Cardiff affects employment sites

• 11% Wales household increase to 2033• Surprising 42% increase in Cardiff to 2033 • 59k increase in households 2006-2026 not 27k (LDP)• So need 2,950 units pa not 1,750• Demands a long term, strategic, greenfield solution • Households decreasing in size: 2.36 pp/hh 2.23• 69% increase in single persons: 55% in single parents• So significant apartment emphasis: ca 36% for 1-2 beds• But 87% supply 1-2 beds (almost all apartments) 2007 • 44% need 3bed and 23% 4bed: 1355 pa: 17% supply• Inequitable, discriminatory, inflexible, unsustainable

Sustainability principles• Rapid transit served, regionally linked• Link medium-high density sub-centres• Walkable/cyclable local communities
• Compact development: 50-100 du/ha• Mixed housing tenure/types/affordability
• Low carbon homes: renewable energy• Integral CHP/waste recycling• Integral, accessible employment
• Generous green frame, biodiverse linear park system
• Sustainable drainage systems
• A public-private-community partnership• Participative ‘Enquiry by Design’ process• A Sustainable Design Code
• A national sustainable exemplar for Wales• A single landowner to provide continuity,
commitment and quality over 20 years

Precedent 2: Newcastle’s northern extension: shows the importance of testing alternative models with multiple criteria: linear solution (left) gave very high accessibility but required major investment in a new transit line: the cellular scheme (right) uses existing Metro stations,invades the greenbelt, but uses higher densities close to stations.

Conclusions
• Must ensure the LDP process develops a credible strategy• Publicly debate all the strategic growth options incl. post 2026• Build cross-party political consensus about long term housing
needs and the way of addressing it• Address social sustainability alongside countryside conservation
• Develop the sustainability criteria to underpin the planning process: the design policies to underpin the strategy
• Establish the public private partnership to drive the scheme, to ensure affordability and energy efficiency, and set up funding
• Ensure the provision of public transport infrastructure to provide access to jobs and services and protect adjacent suburbs
• Develop the design/development team, masterplan, code (?) and competitive processes to deliver sustainable extension(s)
• A ‘world class city’ needs world class suburbs
