The interior spaces were designed by interior architects Alexandra Selig and Carl Renault. To balance the mineral aesthetic of the house, composed of raw concrete, metal, and glass, the duo incorporated soft textures, rounded forms, and a broad color palette. Most of the furniture was custom-designed for each space. One of the interior walls is entirely covered with a printed sky motif, its tones shifting across the floors to create a gentle ambiance that celebrates the project’s verticality.

Wild Rabbits Architecture has crafted an airy design, defined by the contrast between the transparency of the interior spaces and the opacity of the structure as seen from the street. The project’s constraints, such as the narrow plot, the height of neighboring buildings, zoning regulations, and the client’s program, led the architects to design a skyward-reaching structure, animated by setbacks and an original “thick façade.”

The façade is draped in an 18-meter-high spiral steel mesh, arranged in an accordion pattern. Typically used in urban or sports facilities, this metallic fabric lends the building a sense of lightness. Its folds create shifting patterns of light and shadow depending on the sun’s position, while effectively shielding the interior from outside views.

The pursuit of natural light, a guiding principle of the project, is embodied in the glass curtain wall, the use of metal grates for the cantilevered balcony floors, and the incorporation of voids and offsets at every level. These features allow light from the rooftop terrace to filter down to the ground floor.

While each floor has a designated function, the minimalist concrete post-and-beam framework leaves the floor plans open, offering near-total flexibility in layout.
