The Situationist urban proposal is a theoretical and practical stance against modern urban planning, which consolidates “collective isolation” and car-based consumerism as a matrix of urban life. In responding to this, the Situationists stress the need to appropriate, as free individuals, the conditioning that has historically imposed functionalist architecture and urbanism. Constant Nieuwenhuys’ New Babylon offers up a synthesis of these ideas through the design of an urban space that seeks the collective creation of a “common place”.
