De Carlo Gualla Architects designed Casa Rosset, a mountainside home that generates all of its energy through onsite renewable sources. Located in Aosta, a city in northwest Italy, the single-family home is organized like a villa with separate but interconnected spaces, eschewing the more traditional compact residential housing type. Floor-to-ceiling glazed sections frame fantastic views of the Italian Alps.
De Carlo Gualla Architects had two main goals in designing Casa Rosset. The first was to develop a spatial organization that responded to the needs of the clients, instead of merely copying the traditional arrangement that lumped all the rooms under a single roof. In the end, the architects adopted a village-like spatial model that divides the home into four separate but interconnected units. The layout, made up of “separate nuclei all linked to communal spaces,” helps accommodate multi-generational living as well as overnight guests.
The second architectural goal was to construct a building with a minimal energy footprint. The architects applied passive design principles to Casa Rosset, which is built into the side of a mountain, allowing the earth to naturally insulate the home. Natural light penetrates the home through the many glazed openings, while timber louvers shield the low-emission glazing from the harsh sun. The zero-energy home generates energy through geothermal, heat pumps, and solar power sources.
