How can collective housing design encourage social inclusion? From an ecological perspective, the housing of socially disadvantaged and transformation of post-war mass housing is explored. Socially disadvantaged people such as the formerly homeless have often difficulties integrating into a new living environment and need a more stable environment. This project aims to provide spaces of interaction as well as seclusion. Productive and collective spaces like a car maintenance shop, a multistory café, urban farming and a canteen allow the residents to come into both formal and informal contact with each other and the neighbourhood. A carefully crafted circulation space as well as differentiation in dwelling typologies allows for chance meetings between a heterogeneous group of residents.
