This is a “solar” volume, strongly articulated to offer the maximum presence of its large open terraces. The staggering of the entire floor plan in the direction of the slope allows maximum use to be made of the roof terraces. Towards the south, the large open terraces are arranged alternately so as not to shade each other and to avoid adding a single square metre to the buildable area. This strong volumetric commitment gives the project a great, unforced expressiveness. It is a set of trays in the sun, a sequence of small raised gardens that extraordinarily enrich the use of the building and its bioclimatic behaviour.
The sun shapes the building to a certain extent. The sunniest façades are opened up with terraces and large glass surfaces exposed to the winter sun and the silence of the garden. A continuous strip functions as a deep façade, like a large climate control diaphragm. In summer, either with a trellis or a system of vertical blinds, the rooms are completely protected from direct radiation, creating an atmosphere of comfortable semi-darkness in the interior. The opposite facades are smoother and are made up of large windows cut into the wall. On the attic floors, which are more sensitive to the sun, a system of lightweight pergolas establishes a versatile method of variable response in the different seasons of the year and draws a less sharp and more aerial silhouette of the building against the sky.
