Tesserae is a platform to connect critical multidisciplinary research, art, education, communication and project development. It focuses on policies and practices dealing with social justice, urban renewal, urban peripheries, community-led processes, DIY culture, migration and housing. We develop participative tools and methodologies for co-creation and commons management. Based in Berlin, Tesseræ works with local communities, independent and non-for profit organisations, as well as local, national and European institutions.
