In chapter six of Rooftopics, Léon van Geest talks to Laurens van der Wal (architect) and Renée Rooijmans (cultural antropologist) about exploring living on rooftops. They are the initiators of what will be the first rooftop village, on top of De Kroon, a former industrial building in Rotterdam-West. How do they see the future of city living? And what challenges did Renée face when she got the chance to live on the Hofbogen rooftop for a year? Discover this, and much more, in this interview.
