This PhD research is questioning construction modes and financial accessibility to housing. It focuses on a prospective research for new production modes for low-cost housing that are valorising territorial resources of Saône-et-Loire and giving priority to a local development. In a time where stakes for territorial attraction are together linked with employment and quality of life, the question of habitat plays a key role. The development of an attractive habitat, economically accessible and favouring the local branches, while reducing the ecological footprint of the construction sector, would contribute to the economical development of the territory. Such a challenge requires an exploration of new solutions in terms of production modes and use of local resources. Firstly, the analysis of the stakes, potentials and brakes of the territory, is based on field enquiries that have been carried out nearby local actors and contractors, and then crossed with outer references. With regard to this exploratory phase, the second step was founded on a prospective reflection. It consisted in understanding and enlightening all possible trends and let emerging paths for developing other kinds and modes of habitat production. These trends are presented in terms of organizational, architectural and construction proposals. In terms of enhancement, several steps of this work were valorised through exhibitions and conferences with a twin objective. On one hand, it consisted in communicating with local actors on the research progresses and to disseminate nearby the great public some examples of architectural achievements that were questioning the traditional design of the habitat, while valorising the local resources, and, secondly, to revive a debate with local stakeholders in order to refine the advanced proposals while integrating their inputs in the reflection, within an iterative approach.
