The challenge of the project is the interior design of the Hauts-de-Seine theater in the town hall of Puteaux. This building dates from 1921 and used to host a neoclassical party hall, it has a certain originality due to its square dome and the presence of bas-reliefs in its central gable. It will find its final function in 1965 by its transformation into theater. The theater has stood the test of time while evolving in its functioning. Although already renovated several times, its success and therefore its frequentation have made it take a few wrinkles. It was necessary to rethink the spaces of the hall, the foyer as well as the stairs, in order to make it more attractive and ensure better profitability. But also private parts such as lodges.
