After the revolution 1974 the SAAL projects by Nuno Portas reinvent the social housing politics in a way never seen before, surrendering all major responsibilities, such as the collection of rents or the comissioning/assignment of building companies to cooperatives and resident associations of SAAL beneficiaries.

o SAAL destinava-se a apoiar, «através das câmaras municipais, as iniciativas das populações mal alojadas no sentido de colaborarem na transformação dos próprios bairros, investindo os próprios recursos latentes e, eventualmente, monetários». Considerava-se que as iniciativas deveriam partir dos moradores, organizados em associações ou cooperativas.” (Gaspar Martins Pereira 14)

The Approach of the SAAL project demonstrates a bottom-up approach of social rehousing politics, that has considered the importance of residents involvement in the rehousing process (planing development, execution and administration) essential/ indispensable. Although SAAL failed and was abandoned already two years after its launch it has achieved great academic attention and has left a footmark in the history of Portugals’ rehousing politics. SAAL has gained international attention due to its opening of local management, a new understanding of architecture and the city itself (…) but finally also due to its attention paid to social and spatial formation of identity.  The abandoning of SAAL in 1976 heralded the temporary end of an interventionist housing politic that aimed to solve dwelling problems of the most deprived members of society in the urban regions of Portugal. Instead the market was again taken over by rampant market speculation and expulsion of the poorest members of society to the outskirt areas of the cities.
