The Saint-Andéol House is a residential renovation and extension project by Paris-based firm Banquet, located in the French commune of Saint-Andéol. Completed in 2023, the project involved a thoughtful integration of old and new, and is situated on the eastern foothills of the Vercors plateau at an altitude of 1,100 meters. The resulting structure harmonizes with the alpine landscape, providing residents with an immersive experience of the surrounding natural beauty.

The project's design focused on seamlessly connecting an older residential structure with a modern extension. The new 50 m² extension thoughtfully respects the original building while introducing contemporary elements that enhance functionality and the occupants' connection to the outdoors. This is achieved through careful attention to spatial flow and strategic material choices.

A key aspect of the design is the strategic placement of windows to frame spectacular views of the surrounding mountains, including the Grand Veymont, Mont Aiguille, and the distant Belledonne massif. The variation in window sizes on each of the four façades plays with the scale of the building and the landscape.

The extension features a distinct material strategy that contrasts with the existing structure. A site-cast concrete base establishes continuity between the terrace and the new extension. A timber frame is built on this base, clad with larch on the exterior and lined with birch on the interior. This reinterpretation of the traditional alpine chalet uses materials that will evolve naturally over time.

A green roof was installed to integrate the new structure into the landscape and contribute to both rainwater management and thermal regulation.
