The Habitats Jeunes Clairvivre association has hosted young people from 16 to 30 yrs since 1962. The project Habitats jeunes et design was initiated in the context of the renovation of the building. It consists of re-thinking space lay-outs by collaborating on the one hand with the residents, and on the other, with the designers Fabrice Gibilaro, Pascaline de Glo de Besses, Patrick de Glo de Besses, Julien de Sousa. The resulting lay-out orientates the uses; colour structures the life of young people. The exhibition reviews the many themes of the project.
