Marie and Alexandre run a design practice from Appartement 50 in Le Corbusier's Cité Radieuse in Marseille. The duo designs objects and textiles, working with glassmakers, ceramists, and carpenters to produce furniture, lighting, and vessels.

‍

Their work uses glass, clay, wood, and lava, combining industrial techniques with handcraft methods. The duplex, restored by Jean-Marc Drut, functions as both living space and showroom. Their objects engage directly with the building's raw concrete architecture while drawing from Mediterranean modernist traditions.

Their work is produced by signé, a contemporary design gallery in Saint-Germain des Prés founded by Maxime Bouzidi in 2021. The gallery represents designers and artists, producing and promoting work across design disciplines.
