Building renovation of a single-family villa of the 70' located in the pre-collinar area, in the province of Turin. The architectural intervention is based on respect for the naturalistic context in which the building is located, on the need for expansion to the ground floor and division into two separate units. The natural character is evident not only in the plant elements placed on all levels but especially in the choice of finishes that define and identify the two units, but above all balance the full and empty resulting from the new volume.
