When I was asked to develop this project, I proposed to the client who lives and works in the countryside, to take a walk to choose together the "place" on which to build. This ancient rite, of which traces have been lost, allows you to begin a journey in which architecture is born right from the outset from an intense relationship with the place and with the people who will live there. It is the project of a wall and a cloud. A wall to the north protects from the cold winds of the plateau: it is thick, material, of tuff like the hill; it is a high boundary wall, its scale is that of the landscape and one loses oneself in it. Against this primary sign, the wall, a low cloud breaks: the roof. It extends to the south to form a large shadow, like a lens without thickness, the color of copper sulphate. There is no facade; it is replaced by immaterial elements, a succession of porticoes, bridges, grilles, are filters between inside and outside, between light and shadow. The house, dug into the profile of the hill one floor deep, appears as if sunk into the ground, enveloped by the surrounding landscape: this effect is determined by the other design choice that characterizes the intervention. In other words, it was decided to dig into the profile of the hill, as can be read from the sections, for the depth of one floor, so that towards the North the building is proposed with a height slightly higher than one floor, towards the South with a height of two floors like an internal courtyard, two sides of which are made up of the natural contours of the land. The excavated soil was used to model the connection of the building to the ground in the northern part.
