Round table on the occasion of the exhibition "Ultimate Matter" at Archizoom, EPFL. The theme of material reuse has recently emerged in architecture schools and has gained momentum in a short period of time. Curricula and research programmes continue to adapt to this new paradigm. The discussion addresses issues such as continuing education, the need to move away from bricolage aesthetics to see reuse develop on a larger scale, the development of new standards adapted to reuse, etc. With Prof. Dr. Madlen Kobi (Social Anthropology Unit, University of Fribourg), Guillaume de Morsier (Kunik de Morsier architectes), Célia Kupfer (EPFL Architect, Doctoral Assistant, Structural Xploration Lab), Mélodie Rey (EPFL Engineer, Real Estate Development at Brick AG), Introduction and moderation: Corentin Fivet (Professor, Structural Xploration Lab, EPFL)
