The Gist
A London council wants to give away cheap or free public land to community groups and housing co-ops instead of selling it to private developers, hoping this will get more genuinely affordable homes built. The author argues this could fix the broken system where private developers water down their promises of social housing, and that if other councils copied this idea, it could meaningfully change how the UK builds affordable housing.
Conclusion
Lewisham council's strategy of giving away public land to community-led organisations (rather than relying on private developers) to build social housing is a promising and radical model that, if adopted nationally, could transform social housing construction across the UK.
Premises
- The current system, in which councils rely on private developers to deliver social housing as part of larger master plans, is broken because developers use their bargaining power to minimise the social housing they actually build.
- A legal loophole in the 1972 law allows councils to give away land worth £2m or less to whomever they choose (including for free), rather than being forced to sell to the highest bidder, enabling land transfers to community groups instead of wealthy developers.
- There is a large stock of underused 'small sites' too modest for major developers to bother with, representing enormous untapped housing potential (e.g., estimated 850,000 homes across London, 9,700 in Lewisham alone).
- Community-led, small-scale developments tend to produce higher-quality housing that contributes more positively to neighbourhoods than the large anodyne developments built by major developers.
- Lewisham has a track record of successful community-led housing projects (Walter Segal self-build homes, Nubia Way co-operative, Church Grove community land trust), demonstrating the model's viability.
- Placing land into community land trusts can lock in permanent affordability, addressing long-term housing needs rather than one-off delivery.
Assumptions
- Community-led organisations have or can develop sufficient technical, financial and organisational capacity to successfully deliver housing projects at scale.
- Low-interest loans and pre-approved planning permission will sufficiently de-risk projects for community groups with less development experience than professional developers.
- The benefits of higher-quality, permanently affordable housing outweigh the slower or smaller-scale pace of community-led construction compared to volume developers.
- Other councils have the political will, administrative capacity and legal appetite to replicate Lewisham's approach despite its added complexity.
- The small-sites land supply identified by RCKa and others is actually available, viable, and not subject to other constraints (e.g., ownership disputes, infrastructure costs) that would prevent development.
