The document provides background information on two cities - Leipzig and Prague - and proposes common projects for underutilized sites in each city. For Leipzig, it focuses on the abandoned IG Fortuna cinema within a former gasworks complex, proposing to establish a productive commons through community participation and collective ownership. For Prague, it examines the decaying Karlin Barracks and suggests an artist residency program and recycling depot that allows impermanence and transformation based on community needs. The projects aim to harness each site's history and involve local communities in designing environments through non-plan approaches.
