Preserving the identity of the location and characteristics of the building concerned was for us the slogan for the intervention. The proposed space appears as a "house inside the house". A "solid" volume landed within the existing space that reacts to the geometry of the shape. In this amount is subtracted from the central area thus resulting in a kind of square separating the different functions of the space. On the one hand, a monolithic volume with a central door is "auditorium" on the other, a volume cut is receiving and store.
