Text description provided by the architects. Located in a condominium surrounded by nature in the city of Canela, in the Serra Gaúcha region, Altos House was designed to serve as a weekend retreat for a family.

On a plot with striking topography, the project’s concept is based on the placement of a pure exposed concrete volume at the top of the site, where one can enjoy unobstructed views of the surroundings and privacy from the front street.

From this vertical arrangement, the building is aligned with the southern side setback, creating a large outdoor leisure area facing north under the shade of existing Araucaria trees. While the front of the house is dedicated to social areas, the back houses the bedrooms, all of which have direct access to the patio.

The main façade stands out due to the large cantilever of the upper volume, which also marks the covered entrance, carved into the topography. At night, the front face, even with the curtains closed, resembles a large backlit screen.

A linear staircase divides the social and private spaces, leading to the rooftop terrace, where one can enjoy a lookout point with a low parapet that also serves as a bench. On the access level, in addition to the covered parking area, there is a wine cellar.

The materiality of the project is quite elemental, featuring exposed concrete, glass enclosures, wood, and natural stone floors, conveying the idea of elegance through simplicity in the solutions. The interiors aim to use the same materials as the external finishes, creating synergy between the inside and the outside. The project is proposed as a backdrop for a daily life filled with enjoyment of the region’s distinctive climate. The generous window frames seek to blur the boundaries between covered and uncovered areas, offering flexibility in layout depending on the external temperature and the residents’ preferences.
