‘strictly speaking, the typology of an A-frame house, related to mountain building in chile, is scrutinized,’ said nicolas del rio of del rio arquitectos associados. however, this didn’t stop the studio from constructing ‘la leonera’ in the country’s los andes mountain range. the project is the result of a collaborative process regarding what must become of a weekend retreat. revisiting decisions with the clients back and forth made its inhabitants active participants in the manifestation of bespoke architecture.

two geometrically independent volumes – a rectangle and a triangle – are proportioned to preserve simplicity within the hillside. the first, in reinforced concrete, becomes the base, containing and blending with the terrain while providing support for its pristine counterpart. inside the A-frame, a long void houses a system of acute timber trusses to provide ambient warmth to its occupants. the craft buttresses on a cement sleigh, which in both extremes, folds upwards to hide the inverted beams and creates an extended perspective against the hillside. in turn, this characteristic develops a platform detached from the ground to deliver a lightness to the space and a log-piling gap above the ground. upon accessing the lower levels, a wooden stair in the far end of the floor plan connects both pieces, which in addition to the strict control over the windows, make the house a continuous experience of tension and dominium of the landscape.

the interior atmosphere is highly insulated with a controlled perimeter. furthermore, the retreat portrays a substantial sun-oriented glazed façade, which captures the abundant winter radiation, using thermal lag to store the heat in the massive concrete components while openings towards colder orientations have been minimized.
