With a woodland backdrop and the horizon ahead, Baroneza House is set into a careful reading of the topography of a sloping site. Designed in the Quinta da Baroneza condominium, in the countryside of São Paulo, for a family that values togetherness, the residence redefines the traditional logic of site occupation and inverts the usual programmatic arrangement. By placing the social level on the
upper floor — the highest point of the site — the design fully takes advantage of the privileged dual view, allowing the space to open continuously toward the landscape.
Two large volumes are articulated by a central reflecting pool, while expansive sliding glass panels promote air circulation throughout the interiors, contributing to cross ventilation and the natural cooling of the house.
Above this fully integrated floor, a glulam (glued laminated timber) roof unfolds into two sloping planes in a design reminiscent of open wings. The structure was conceived to maximize the entry of natural light while ensuring shading and thermal control. Rarely seen in Arthur Casas’s work, the use of a roof form explicitly associated with traditional pitched roofs becomes one of the central elements of the project, requiring rigorous technical development to define alignments, wood tone, and construction precision. In addition to its environmental performance, the timber structure enabled a dry-assembly system with prefabricated components, providing greater agility during the construction process.
The materiality of the house reveals itself differently in each overlapping volume.
The upper body appears in exposed concrete, crowned by the timber roof — the most expressive element of the project. The lower volume, partially embedded in the ground, also combines concrete and wood, though in a more restrained way and more integrated with the terrain. Natural stone flooring extends from the
interior to the outdoor areas, establishing visual continuity and directly dialoguing with the pool, which is also clad in stone.
On the lower level, glass bricks allow zenithal lighting into the stair hall that provides access to the suites, organized around a garden protected by a retaining slope that separates the house from the street and public sidewalk. This
configuration ensures abundant natural light, privacy, and a direct relationship with greenery without exposure to the immediate surroundings. The layout prioritizes clear and efficient circulation, with smooth transitions between collective spaces and more private areas.
In the living room, the furniture is arranged to preserve spatial flow and visual axes.
Embaúba (Studio Objeto) and Brasiliana (Jorge Zalszupin) sofas, PL61 armchairs (Percival Lafer), and pieces designed by Arthur Casas — such as the Galo, Belterra, and Ettore side tables — structure the environment. Adi coffee tables and jacarandá pieces dialogue with artworks, including the sculpture Cabeça Jesus, by the artisan Nicola.
In the gourmet area, the Amorfa table, designed by Arthur Casas, is paired with Alagoas chairs by Michel Arnoult and the Sênior armchair by Etel. In the home theater, the Match sofa, side tables, and signature lamps by Studio Objeto coexist
with the Mole armchair by Sérgio Rodrigues and Aiso coffee tables, composing a more intimate environment. The game room and outdoor areas bring together pieces by Jorge Zalszupin, Arthur Casas, and furniture designed especially for
outdoor use.
Casa Baroneza thus establishes a direct relationship between architecture, structure, and landscape. By inverting the traditional program, exploring passive environmental comfort strategies, and adopting a high-performance timber structure as a central design element, the residence proposes a way of living that combines technical precision, constructive clarity, and an intense use of collective spaces, integrating consistently with the site and its natural surroundings.
