The Folding House in Las Cabras, Chile was strategically wrapped with a wooden “flap” to give the owners optimal temperature control throughout the year. Designed by Santiago-based B+V Architects, this unique home prevents excessive solar radiation during the searing hot summer months while inviting the heat in winter, through the movement of the “flap”. In addition to providing year-round temperature control, the responsive design element pulls double duty as a sun-streaming cover for the rooftop deck, which offers spectacular lake side views.

The stunning 900-square-meter home was tucked into a steep incline, exposing it to the area’s high temperatures. To create a responsive design that wouldn’t sacrifice aesthetics, the architects added the double-ventilated wooden façade as an attractive and protective element. The feature allows the homeowners to enjoy the amazing lake views year-round from the comfort of the outdoor deck, without overheating in the summer months.

The double ventilated wooden flap facade shades the home’s exterior walls and roof. In summer, the wooden facade acts as an eave that protects the home from excessive solar radiation.

During winter, on the other hand, the wooden envelope allows heat to enter the interior, which is stabilized by high-quality insulation, as well as elimination of all thermal bridges. For additional heating on cloudy days, a small wood-burning stove can be fired up.

On the interior, large floor-to-ceiling windows flood the home with natural light and also enhance cross ventilation when opened. A large open courtyard sits in the center of the interior, seamlessly connecting the exterior with the interior.
