On the top floor of a 1970s building, Romain and Constance have transformed a forgotten apartment into a luminous family haven, where concrete, wood, and metal interact in perfect harmony.
“We were immediately attracted by the building’s mineral quality,” say Romain and Constance, both architects. When their daughter Mara was born, the couple were looking to move away from the center of Paris, and discovered this apartment in Maisons-Alfort, which had been on the market for a long time and had a very Seventies aesthetic.
Behind the worn carpets and yellowed wallpaper, they immediately saw potential: “The large dark wood frames, the concrete slab… our favorite materials were already there!”
Rather than erase, they choose to reveal: “We didn’t want to demolish everything, but to work with the existing,” they explain. The original features then became the common thread running through the project, in an approach guided by raw materials and a certain economy of means. The space was completely rethought and redistributed to accommodate a second bedroom, without extending the walls.
The result: an interior that’s both sober and warm, where walnut responds to the original woodwork, and polished concrete captures the light and softens perception. “We love the quality of the light here, from morning till night,” confide the owners. A fluid, breathable space, designed to last – and to be lived in.
