A striking residential project in Fontenay-sous-Bois, France, demonstrates how contemporary architecture can thoughtfully integrate with urban boundaries while maximizing natural light. The Maison SurLeMur, designed by architecture firm arba and completed in 2022, represents an innovative approach to small-scale residential design within a constrained urban environment.
The 132-square-meter dwelling is strategically arranged along a street-facing boundary wall, which has been preserved in its original state to form the masonry base visible from the street. This design decision creates a seamless integration between the new construction and the existing urban fabric, while establishing a strong foundation for the architectural intervention above.
The structure is crowned by a distinctive 30-degree double-sloped roof crafted from red pigmented zinc with standing seams. This roofing solution not only provides weather protection but also contributes to the building's distinctive visual identity within the neighborhood context. The choice of red pigmented zinc creates a bold architectural statement while maintaining durability and low maintenance requirements.
Between the preserved masonry base and the zinc roof, vertical slats of raw wood serve multiple functional purposes. These carefully positioned elements filter and direct views toward the public space while allowing abundant sunlight to penetrate the dwelling's interior. The slats also enable the gables to be opened without creating unwanted sightlines to adjoining buildings, effectively addressing local urban planning regulations regarding privacy and visual intrusion.
The wood slats are set against a backdrop of black pine resin-coated wood cladding, creating a rich textural contrast. These larch slats are positioned to rotate slightly from west to east, generating a dynamic kinetic effect when viewed from the street. This subtle movement creates visual interest and helps the building engage with pedestrians and passersby in an ever-changing manner throughout the day.
Inside the residence, the luminous, abstract belt formed by the filtered light creates a dramatic backdrop for the common area located on the upper level. This space has been specifically designed as an observatory for the Vergers de l'Îlot, offering generous views to the northeast at the rear of the building. The interior arrangement maximizes the connection to the surrounding landscape while maintaining privacy from the street-facing elevation.
The project exemplifies how thoughtful architectural design can address multiple urban challenges simultaneously, including privacy concerns, natural light optimization, and integration with existing neighborhood character. Through its innovative use of materials and careful attention to orientation and views, Maison SurLeMur demonstrates that small residential projects can make significant contributions to urban environments while providing comfortable and light-filled living spaces for their inhabitants.
