Though the house was originally projected for a permanent use, later it was transformed into this other one, no longer in reinforced concrete, a third smaller and for a temporary use. We did not only try to keep its luminous and relaxed presence but to trace it on top of a kind of fictitious footprint of the previous project. Atop the existing artificial podium, the new house extends horizontally following the sinuous river at the foot of the hill. The dominant position of this piece establishes a double front articulated in its interior by a regular sequence of identical rooms. Towards the open landscape there is a continuous arrangement of common functions and to the immediate hill there is another discontinuous one with individual functions. Each side has five rooms with a system of openings in the exterior walls indifferent to orientation or program and another system of apertures in the interior walls that is relative to the degree of privacy from one room to the other. Both sequences are structured by another system of ceiling apertures that forces diagonally the perception of the plan’s depth. The house’s center is blurred by a couple of tangential perforations that unify the rooms at every side. The perforated ceiling extends beyond the interior and separates each of the four sides with heavy shades.
