Córdoba-based firm Alarcia Ferrer Arquitectos has just unveiled a stunning, green-roofed vacation home in Argentina’s remote Calamuchita Valley. The rocky, sloped landscape drove the inspiration for Casa FM’s design, which is a massive concrete 3,444-square-foot structure with a rectangular shape that juts out over the mountain ledge, offering dreamy views of the valley below.

The architects chose to use concrete as the primary building material mainly for its low maintenance properties. Using a simple rectangular shape, a concrete shell adds strength, flexibility and insulating properties to the structure. Its low stature and expansive green roof stretches out over the entirety of the home and also helps blend the structure into its natural surroundings.

Casa FM is actually comprised of two autonomous houses, with the lower one-bedroom house embedded into the terrain and the second level housing two bedrooms. Connected via a stone staircase adjacent to the building, each of the two spaces was designed to offer guests an intimate relationship with the surrounding environment.

The interior is clad in the same smooth concrete as the exterior. Rectangular skylights flood the living space with natural light, providing a sense of contrast with the concrete walls and flooring. Warm wood furnishings along with leather couches and woven rugs give the space a welcoming, cozy feel.

Like most houses that were built around amazing landscape, the interior design of Casa FM was laid out strategically to make the most of its setting. All of the rooms lead toward the open-plan living room, which features one long floor-to-ceiling glass wall. From this main living area, an expansive open patio space offers spectacular, unobstructed views of the valley below and the surrounding mountain range.
