The project arises from the manipulation of a continuous surface using two operations, court and folded, solves the whole program. Thus it appears as an object that does not go out of the area, settles on him. Without jumps or discontinuities, the envelope plays topologically at being external and internal face, floor, wall, ceiling, forged and cover. The internal program is solved likewise by diaphanous and interconnected spaces, changing height sequentially to solve the different scales. It is an object capable of being extended or cut away without the set to suffer, since it is the result of an open process.
