A folded metal roof tops this holiday home by Chilean firm Mas Fernandez Arquitectos, which was built using simple, cost-effective materials.

The BL House is located in Aguas Claras, a coastal area in Chile's Valparaíso region. Nestled within a hilly, tree-covered landscape, the house was designed to provide a strong connection to the "peaceful, native surroundings".
From the project's outset, the architects were mindful of keeping costs down and minimising construction time. The aim was to create a "simple, low-cost and efficient? dwelling.

"The house is thought out from its beginnings with prefabricated and modular materials, engaging in a fast execution that lowers the construction cost and enables the owners to inhabit the house in as little time as possible," said Mas Fernandez Arquitectos. In response to the site's gentle slope, a portion of the home is gently lifted above the ground via concrete pillars. Rectangular in plan, the building was constructed using steel framing and structural insulated panels (SIPs).
"The latter one not only supports the structure, but at the same time delivers an excellent thermic isolation, according to the weather conditions normally encountered in this area," the studio said.

Exterior walls feature a mix of dark pine cladding and large stretches of glass. A faceted roof made of zinc and aluminium covers the house, dipping down in some areas and rising up in others.
