The first instalment of the ‘Urban School Ruhr’ series, this volume draws from and reflects upon the learning platform’s experiences to date, while also looking to the future of urban practice in contemporary cities. It asks how we can best learn city-making, as well as how we might understand the political concept of communing for this purpose. Additionally, it explores the dialogue around intervention as a strategy for enacting urban change. A range of contributors build upon Urban School Ruhr’s foundational belief that experts and amateurs can together enact a space of critical exchange and knowledge transfer. Conversation, after all, is the first step to co-producing cities.
