Thailand's Baan Mankong made slum communities their own housing developer

Thailand's slums faced the standard dilemma: eviction, or slow, expensive public housing that usually pushed people far from their jobs. In 2003 the government launched Baan Mankong ('secure housing') through the Community Organizations Development Institute and reversed the delivery chain — instead of contractors building housing for the poor, infrastructure subsidies and housing and land loans would flow directly to low-income communities, supporting upgrading in place wherever possible.

Communities work out their own land tenure solution — collectively buying the land they occupy, negotiating long-term leases, land-sharing, or permission-to-stay — using the finance as leverage with landowners. Holding land through cooperatives under Thai cooperative law is the program's quiet invention: with equal shares and a joint monthly repayment, one member's default threatens everyone's housing, which makes collective management structural rather than sentimental. Citywide poor networks run the surveys and planning, so thousands of small projects add up to one citywide program.

The scale came: over its first fifteen years the program supported 103,538 houses across 343 Thai cities and towns. The World Bank's 2014 review of ACCA — the program that spread this community-driven model across Asia — credited Thailand's national CODI implementation as the successful precedent and documented the model's economics: ACCA spent on average only $58,000 per city, yet governments contributed $75.7 million, roughly 94 percent of total project value, and 274,000 savers accumulated $22.5 million in collective savings.

Make the community the developer: fund it directly

Money flows past the intermediaries: no contractor margin, no municipal bottleneck, and the organizational capability stays with the community after construction ends.

Collective land tenure through cooperatives makes cooperation compulsory — shared land and joint repayment force collective budgeting and planning to exist.

Support targets demonstrated commitment: communities that already save and plan reveal 'signals of seriousness', so subsidy lands where it will be used well.

Citywide surveys and poor-run networks let thousands of community initiatives form one negotiable upgrading plan, which made the model scalable rather than a set of showcases.

Housing programs fail when institutions build for the poor. Pay communities directly and the subsidy buys an organization too. Collective land tenure makes cooperation compulsory.

The model became a regional export: ACCA (2009–2012) applied the same community-fund-and-network approach in 165 cities across 19 countries, seeding city development funds in 98 of them, and the World Bank review found it transformational while cautioning that impacts beyond three years were not yet evaluated. In Thailand, Baan Mankong passed its fifteenth anniversary in 2018 with more than 100,000 houses built. Practitioners note the tension: cooperative committees can concentrate power, and genuine collective management takes constant work.
