3 rooms, 3 spaces; 3 floors, 3 ceilings: of wood, the rest intact as well as time so the building has returned them, all whitewashed. The floor like the ceiling, the same weave same texture; only, the latter, bent on a hut, with asymmetrical flaps: regular square birch plywoods - 1m x 1m - to the size of the rooms. A grid - for all sorts of wiring - to fill the outdoors of every masonry construction that is respected, is reflected in the shadowy void that bends the ceiling panels; a shadow line, however, requires alignment and assembly molding, separating the panels between them, slotted to the ground by thin solid frames with colored glass inserts at the intersections: yellow, red, accquamarine, for the 3 rooms. Yellow, red, gray-blue, also enamelled wooden doors, to slide on synchromious "panels" that recover the "lead" of the wall. Metal external fixtures - unpainted galvanized iron - applied outside to overrun frames: still a quadrangular measure of the world's variation and its vicissitudes.
