Located in a wooded area on the outskirts of a small city in central France, the concert hall in Limoges can accommodate up to 8,000 spectators. The concept for the project began with a double envelope: an outer skin made of wood arcs and translucent rigid polycarbonate sheets and an inner acoustical envelope of locally grown Douglas fir. The site—a clearing within a large forest, surrounded by trees that are more than 200 years old, in a region with an active lumber industry—suggested the use of wood.
