Abstract : Through an immersion survey at the Saint-Nazaire region urban planning agency, this thesis analyzes the promises, tests and effects of setting up inter-territorial experimental approaches around peri-urban housing. First, it documents the resources and constraints of the actors in the conduct of urban planning in peri-urban situations. The analysis reveals the multi-positioning of urban planners who try to find catches through the transformation of project engineering. The latter shows the emergence of a logic of experimental action and exploratory engagements. Nevertheless, these approaches generate tests, whereas the modalities of coordination in planning, in the peri-urban area, are rather characterized by ordinary logics of action (regulatory approach, strong presence of private actors, short-term and sequential urban planning). However, engineering of hybrid residential projects is being built, favouring new coalitions of public-private actors, as well as hybrid urban figures promoting the qualities of individualized dense housing. Finally, the analysis of the effects of the experiments reveals a transformation of the production systems of peri-urban housing marked by the emergence of an urbanistic culture. This work thus characterizes the structuring of a peri-urban "third urbanism" that makes it possible to overcome urban-rural dualism, to break with the idea of the diffusion of an urban model and to consider peri-urban configurations as the fruit of urban planning practices resulting from the combination of the city and the countryside.
