Who we are

We have been an active collective in Barcelona since 1998. We work on architecture and city wide issues from a grassroots perspective. We develop processes of citizen participation on recovery of the industrial and cultural fabric; temporary and permanent interventions in spaces and public buildings and sustainable social housing initiatives. We conduct courses and workshops in different countries and we are passionate about co-learning situations. We promote and co-design digital tools, manuals and open-source guides for their application in processes related to participatory urbanism.
