SUSTAINABLE HOUSE

This house of very simple lines in the middle of the countryside, is designed for a young couple. It responds primarily to the main request of the client which was to be an energy-sustainable construction.

The first parameter we observed was the orientation of the project. The house faces north in all its long façade providing an abundance of light but also sun radiation through big double-glazing windows. On the contrary, on the south façade, the walls made of aerated cement blocks are mostly closed creating a barrier against the leak of thermal energy from the interior.

The terrain is mainly clay and, because the dwelling is located in a rainy zone, the decision was to rise the main level to around 600 millimetres to avoid any chance of flooding. The fact that the structure is elevated from the natural ground allowed us to create a massive floor for thermal absorption so, in winter, all the radiation provided from the exterior would warm the concrete slab and the underneath compact filling. After some time and during the cold hours of the day, the floor mass would radiate energy to the interior helping to keep the thermal comfort of the space.

The roof is also special. It provides generous eaves that protect the glass panels from excessive radiation during the hot season. Also, the proposal contemplates a triple- layer composition of the structure that covers the dwelling. At the bottom, a conventional ceiling conceals a very important package of insulation. Above this, there is a metal cover which collects the rainwater and transports it towards the downpipes. On top of the structure, permeable timber decking protects the metal roof against excessive radiation but also allows the inhabitant to use the surface as a recreational area and enjoy the views of the natural surroundings.

A small volume at the second level containing a study, bedroom and bathroom completes the house and gives access to the roof terrace. Some isolated structures emerge from the timber surface of the deck to provide natural light and cross ventilation to the interiors on the lower level.

Finally, the geometry of the building completes the arrangement of this large site, creating a clear front yard and organizing the rest of the areas dedicated to an orchard, fruit trees, swimming pool, carport and services areas.

Material: Aerated cement blocks, glass, concrete and timber. Area: 250 m²
