Maison Trombe

Maison Trombe, located at 9 Rue du Four Solaire in Font-Romeu-Odeillo-Via, France, was designed by architect Jacques Michel and engineer Félix Trombe in 1967. This residential building exemplifies passive solar design, featuring a Trombe wall—a south-facing, insulated wall with a glass exterior that captures and stores solar heat. The structure is constructed with reinforced concrete and is situated on a terraced rock formation, reflecting the region's mountainous terrain. This project is among the early applications of passive solar heating in France.
