Built on a steeply sloped site — with nearly fifteen meters separating the street level from the lowest point of the lot — Casa Proner begins from the challenge of building amid topographic adversity without erasing the natural terrain. The clients’ request to develop the entire program on a single level became the starting point for an architectural solution that reconciles accessibility, lightness, and integration with the landscape.
The prefabricated steel structure, assembled on site, emerges as both a logical and constructive response to the constraints imposed by the terrain. More than a technical or structural system, it becomes language: the house rests on a set of slender pillars and fine diagonal braces that recall the vernacular architecture of stilt houses. In place of water, a dense native vegetation covers the foot of the slope, forming a green bed that supports the house and subtly grounds it within the landscape.
The program unfolds across two main volumes, connected by a glass walkway — a transparent bridge that opens toward the forest and dissolves the boundaries between inside and out. The first volume houses the social, leisure, and service areas; the second, set back and more secluded, contains the private wing, including the main suite, two bedrooms, and a study. Transparency and the linear layout allow most rooms to open toward the cerrado of the Central Plateau, establishing a direct relationship with the view and the light.
Casa Proner is, above all, a delicate reconfiguration of the meeting between architecture and landscape. The project preserves the site’s natural features and emphasizes vegetation and light — elements that together shape the atmosphere of a suspended house, where the horizon reveals itself in its full expanse.
