This is a compact piece with three stacked floors. Its internal logic has two basic dimensions: a regular horizontal one and an irregular vertical one. Each floor plan is an unspecific grid of walls and openings that configure cubic rooms. The horizontal plane between every level reinforces the difference of rooms by means of singular incisions. These cut outs are not only individualizing every room (or the identity of every corner) but also promoting a vertical interaction though the rooms (in a sort of friction, of veiled presence or potential collectiveness). The building is composed of fifty-eight cubic modules of six, four and three meters. With time, the neutrality and transparency of each spatial unit should confirm an erosion of the given program.
