Stéphane Lemoine is trained as an architect. He directs the architecture, landscape and urban planning agency AP5, which has been carrying out urban reconfiguration projects for 15 years in the metropolises and medium-sized towns of France (Lille, Paris, Toulouse, Dreux, Melun, Chalon, etc...). The projects define an architecture for human movements, but also those of nature, through multiple temporalities. Several actions and articles on mobility have been produced for the Ministries of Culture and Sustainable Development. Teaching on the dynamic representations of the territory was carried out in a school of architecture (Marne la Vallée and Malaquais in Paris).
