New forms of collective spaces are emerging in the European cities: these represent an answer to privatization and lack of good quality in the urban public space. The research project arch / commons is an atlas that collects spaces and practices related to the process of commoning within the urban landscape. Starting from the concept of Spatial Commons, the projects collected in the atlas include bottom-up community gardens, temporary and permanent re-activation of urban voids, open spaces related to co-housing projects and more.
The aim of arch / commons is to define the possibility of commoning as a design strategy, not only as a social process. Analyzing the spatial and contextual characteristics of the selected projects, it is possible to identify theoretical concepts that put in the center of the architectural design process the relation between space and community. With this design attitude, more inclusive and democratic urban spaces can be developed in the future.
