Today the social house concept needs to be re-focused integrating a new ecological, economical and cultural awareness in a stratification of different places and activities, as a new form of Heterotopia. The building is composed by two symbiotic elements: the residential block and the organic ecological wire-frame structure climbing on it. The first element is specifically shaped to gain the best sun exposition, and to optimize the triangular shape of the site. The second one develops from the ground floor to the top as a light metal grid, supporting phyto-purification systems and suspended agricultural fields. The basement is open, to create a viable urban space, linking the surrounding roads together. A 3D printing fab-lab, a canteen and a bicycle workshop are hosted in this ground-level area. The functions involved in this residential building make it an example of a new sustainable and self-sufficient way to conceive social housing in a post-industrial and post-capitalistic society.
