The steep topography of the plot and the needs of the Swiss-Brazilian family were the starting points for both concept and design. With a height difference of more than 10 meters between the street-level entrance and the back of the site, the house was carefully organized into three main volumes: the garage, the swimming pool, and the main dwelling. Positioned at street level, the garage anchors the lower end, while the house occupies the top of the plot. Between them, the swimming pool and a reflective water mirror create a gentle transition, visually connecting the two extremes and enhancing the experience of moving through the site.
The house itself is a simple rectangle in plan. Common areas are located on the first floor, seamlessly extending to the swimming pool and outdoor terraces, while the bedrooms occupy the upper level, capturing sweeping views of the surrounding hills in the Piracicaba region.
A pre-existing stone wall is a central feature of the site. The new building was sited to honor this element—preserving its character while clearly defining the contemporary additions.
The clients requested a concrete house, and all structural and architectural walls are therefore expressed in exposed concrete. To optimize construction efficiency, a modular system of reusable plastic formwork was employed, reducing material waste, lowering costs, and avoiding the extensive use of wood typically required for formwork in this region. The result is a building that harmonizes with its steep landscape, celebrates the site’s history, and embodies a thoughtful, resource-conscious approach to construction.
