Founded in 2012, Plan Común provides strategies to maximize and reinforce public and collective space -un-derstood as a key aspect of architecture, regardless of its scale or program- by means of simple architecture tools, through a critical discourse, research, design and building. We are convinced that radical, basic -even silent- forms are more likely to be relevant and universal, and serve as a support for collective use and imagination. We use a critical and strategic approach towards briefs and com-missions, in order to question and transform spatial hier-archy and uses. We intend to work within an ethic of the collective aiming at relevance and usefulness for the many. Since September 2018, Plan Común is based in Paris, France.
