San Rock is conceived as a mountain retreat in the commune of San Roque, designed for outdoor sports enthusiasts. The architecture is organized into two pure volumes anchored into the slope, distinguishing the private brick-clad ground floor from the social area on the upper level. The design takes advantage of the natural slope to create a double-height space and culminates in a terrace that captures panoramic views of the Punilla Valley. It is a proposal of strong tectonic expression that integrates functionality with a direct relationship to the mountainous landscape.
