With this experimental process, we wanted to demonstrate that access to new materials deposits rely on new relationships with the ones in charge of deconstructing and dismantling buildings, the ones who salvage and implement materials. An improved focus on the already existing resources and materials would allow to reduce our consumption of primary resource as well as avoid the production and accumulation of wastes that then need to be dealt with. It an ongoing research toward an architecture characterized by sobriety and pertinence.
