Guillaume, a well-known home design shop, has relocated to 34 Rue Bonaparte in the fashionable 6th Arrondissement of Paris. The new shop sits within a beautiful Haussmannian limestone building. Black and white terrazzo floors, peach lacquer walls, and an illuminated brass ceiling envelop the ground floor, harmoniously introducing a fresh graphic language into the traditional context. In the center of the space, an articulated blackened steel structure integrates slate display boxes, walls, and a staircase of black-stained oak into a single infrastructural moment. Curved mirror corners blur the shop’s boundaries while distributing fractal light patterns throughout the space. These moments create a distinct brand identity for the Guillaume store as well as a unique destination within the historic district.
