Based on the concept of transitory urbanism, La Belle Friche supports urban transformation projects, both in their preliminary phase of studies and test and in their animation during the construction period. It is thus possible to test new uses that can influence the future project. Strongly sought especially in the context of calls for innovative urban projects, La Belle Friche wished to rethink its editorial line as well as its communication tools. La Belle Friche chose Les Grandes Idées to help them in their positionning.
