Baroneza House by Studio Arthur Casas
Baroneza House is a 2024 residence in Bragança Paulista, Brazil, by Studio Arthur Casas. Set on a sloping site in Quinta da Baroneza, the house turns to the landscape and shifts its social level to the upper floor. That move opens the plan to broad views, brings in light, and gives the family a clear connection between indoor rooms and the wooded setting.
About Baroneza House
With a woodland backdrop and the horizon ahead, Baroneza House settles into a careful reading of the sloping terrain. The residence stands in the Quinta da Baroneza condominium in the countryside of São Paulo, where it turns the usual logic of occupation upside down to serve a family that values time together.
The social level sits on the upper floor, at the highest point of the site. From there, the plan opens continuously to the landscape and takes full advantage of the dual view, while the lower level remains more sheltered and close to the ground.
Two large volumes are separated by a central reflecting pool. Sliding glass panels run across the interiors, encouraging air movement, cross ventilation, and natural cooling without interrupting the relationship between rooms and the outdoors.
Above this integrated floor, a glulam roof stretches into two sloping planes. The form recalls open wings, and it is used here to draw in natural light while providing shade and thermal control. For the office, the pitched profile also demanded close technical work, from alignment and wood tone to the precision of assembly.
The material palette shifts as the volumes overlap. The upper body is exposed concrete, topped by the timber roof, while the lower volume is partly embedded in the terrain and works in a quieter mix of concrete and wood. Natural stone flooring continues from the interior to the exterior and meets the pool, which is also clad in stone.
On the lower level, glass bricks bring zenithal light into the stair hall that leads to the suites. Those rooms are arranged around a garden protected by a retaining slope, which separates the house from the street and public sidewalk and gives the interiors privacy without cutting them off from greenery.
Inside, the living room is organized to preserve movement and clear visual axes. Embaúba and Brasiliana sofas, PL61 armchairs, and Arthur Casas side tables shape the setting, while jacarandá pieces and artworks add texture and contrast.
The gourmet area, home theater, game room, and outdoor areas each carry that same discipline into different settings. Furniture by Arthur Casas, Studio Objeto, Jorge Zalszupin, Michel Arnoult, Etel, Sérgio Rodrigues, and others supports rooms that shift from collective use to more intimate moments without losing clarity.
Baroneza House ties architecture, structure, and landscape into a single sequence. By inverting the program, relying on passive comfort strategies, and making the timber roof a central element, the residence offers a precise, direct way of living close to the site.
