Located in a suburb called Fives, this uniquely enlarged home stands out from a row of ordinary brick houses. As if it has grown overnight, the top floor is covered by entangled wooden battens, to resemble a nest. Painted in a red-orange hue that matches the window shutters, front door and brick houses around it, this nest-like addition isn’t purely for aesthetic pleasure.

The unique wooden structure enhances insulation and lowers energy usage. The elevation has two front openings, one clear window that lets natural light flood the spaces, and another, with “branches” spread over it, that filter excess light and keeps the interiors private. Bright interiors featuring birds’ wallpaper and clear wooden floors complete this French family nest.
