The migratory flows that characterised Europe between the 1950s and the 1990s made Austria a destination or transit country for refugees seeking political asylum or humanitarian reception. The district of Simmering, on the outskirts of the city of Vienna, is a suitable place to respond to the growing housing’s need by converting abandoned barracks in the area into dwellings for refugees. Perceived as a satellite reality of the city due to the decentralisation of the territory, it is necessary to identify urban planning strategies that allow the development of projects that meet the needs of the inhabitants, involving them with a participatory approach in the definition of objectives, contributing to the creation of a multicultural community through the design of urban spaces that avoid any form of spatial or social segregation.
