The Folding House is a Passively Cooled Home by B+V Arquitectos

B+V Arquitectos were contacted by the owners of this property back in 2014. They asked them to create a home that would take advantage of the stunning views of a nearby lake. The project has been dubbed The Folding House.


The house is set in the region of Las Cabras in Chile, and overlooks Lake Rapel. The region receives an excessive amount of heat from the sun during the summer months, something which the designers had to account for.

The site contains a total of 9,655-square-feet (897-square-meters) of which the house occupies 936-square-feet (87-square-meters). According to the architects, the budget, coupled with the challenges presented by the site (high temperatures, and a sloping site), lead to the design of a small but functional home.

The structure is actually composed of Structural Insulated Panels (SIPs). These provided a good base for resisting the summer heat load when used in combination with a number of other cooling strategies. Those strategies include a large overhang that provides solar shading, a double ventilated wooden façade, and cross ventilation.

During the winter, the sun is lower in the sky, and more of the solar radiation is permitted to enter the home, helping to keep it warm when needed. This, and a small wood-burning stove, is all that’s needed to keep the house cozy during the winter months.

The interior has the living spaces spread out over a single level. Both gable ends of the Folding House contain bedrooms, with the in between containing the shared living rooms. On the left-hand-side of the plan, you’ll find two double-bed bedrooms, separated by a bathroom.

The same is true of the right-hand-side: there are two single-bed bedrooms, with a toilet set between them. The living room/study and kitchen/dining room both flank a central sheltered patio.

  1. like but seems to bland, needs more paint and do not like glass doors from ceiling to floor. One is security especially if by yourself. Have possible vertical blinds are curtains with the backing to reduce heat from the sun especially in the hot summer months. I have learned something many years ago while living overseas in the Marshall Islands, put Reynolds wrap on the windows and tape it. cools down the room during the year when you have your air conditioning on or fan and keeps the sun out when you do not want it to hit you with beams of light when you are trying to read or cook or do the 1000 of things thru out the day.
