This project is for a music hall complex including a multi-purpose hall, classical music hall and school of music, located on Seguin Island in the western suburbs of Paris. As described in Jean Nouvel’s master plan for the island, a concrete wall defines the perimeter of the site along the water’s edge. Set within this wall is a large multi-purpose hall which is surrounded by a lush green landscape. As the perimeter wall eventually diminishes towards the leading edge of the site, the hexagonal wooden grid shell structure of the classical music hall emerges. Surrounding the grid shell structure is a large triangular solar panel mobile sail. The sail’s ability to follow the path of the sun, allows for increased efficiency of the solar panels as well as providing a solar shield for the lobby behind. This environmentally friendly sail will ultimately become a new identity for the complex.
