This building is composed of a hall with 1,600 seats in the north part of the building and two halls with 1,000 and 600 seats in the south part. For the halls and the interior core of the building, the work of the architects of Arte Charpentier Architectes covered the rationality and purity of the volumes. The metal skin of the building has been designed to play with light while reflecting the lights of the sky in a sensitive and varied way. The building is thus designed like an urban sculpture, ordering and qualifying all the surrounding space. It thus becomes an element of social and urban identity, both an iconic building for the city and a place of appropriation for the inhabitants.
The particularity of the building is to be a kind of theatre opening onto the town. Through the arrangement of a window in the heart of the building, this itself becomes an open stage. Shows can then take place on the esplanade created under the building, thus offering a prospect from the Town Hall square and a view of the river. This «window» then contributes to enhancing the building within the whole urban composition.
