32 Bagnolet: A Radical Duplex Metamorphosis

architecture-design · 2026-05-13

In Bagnolet, two vertically stacked apartments within a 2000s building have been transformed into a single duplex. The project strips interiors to raw essentials, making structural engineering legible. A massive concrete beam cuts diagonally across the plan, supporting a new slab opening and leaving a triangular ceiling void exposed. New pale aggregate concrete contrasts with the dark original slab, marking the construction timeline. The beam continues uninterrupted through lower-level walls. A vibrant yellow volume envelops the staircase, anchoring vertical circulation. A dropped blue ceiling organizes utilitarian zones on the main floor. Kitchen surfaces are crafted from polyethylene, the plastic used for professional cutting boards, with a yellow hue borrowed from food safety codes for poultry preparation. The design uses color as an active force producing space.
