Other Projects by STUDIO ARTHUR CASAS
Grama House
Itupeva, SP, Brazil
Located at Fazenda da Grama, a residential condominium in Itupeva, São Paulo, Grama House is a single-family residence designed by Studio Arthur Casas for a couple and their three children. With the optimization of ventilation, natural lighting, and integration with the outdoors as its central premise, the house was conceived by exploring the gently sloping topography of the site and its corner-lot condition, free from visual interference from neighboring properties.
The architectural concept is predominantly organized on the ground level and articulated through split levels, resulting in a spread-out floor plan that adapts to the terrain and enhances contact with the exterior. This strategy allows for multiple openings, often filtered by motorized brise-soleils that control the incidence of natural light and reinforce thermal and visual comfort. Cross ventilation and natural lighting guide layout and site-planning decisions.
The program is distributed over two floors, favoring fluidity between spaces. On the ground level are the social entrance, garages—including one dedicated to the homeowner’s vehicle collection—and service areas. The main living spaces are located on the upper floor, organized through split levels: the lower level concentrates the social areas, such as the living room, dining room, kitchen, gourmet space, and swimming pool; the upper level houses the suites and a pilates area.
The office occupies a singular position, projecting in an 11-meter cantilever over the social entrance and also functioning as the roof of the porte-cochère. This space constitutes the project’s main structural gesture. In addition to acting as a symbolic formal element of the house, it required a precise structural solution, with steel trusses fixed into 50 x 50 cm columns. The technical complexity was heightened by the fact that the greatest live load is concentrated at the cantilever’s extremity, where fixed millwork is located, demanding rigor in both detailing and execution.
The materiality of the residence establishes continuity between exterior and interior. The façade combines rough stone with plaster, wood, and metal, while the interiors feature wood panels, textured paint, and the same stone-and-plaster system used outdoors. This choice reinforces material unity and constructive coherence throughout the residence, while creating a balance between structural robustness and sensory comfort.
The interior design follows the same material and spatial logic as the architecture. In the living room, highlights include the Rest and Ela sofas, the Mistral side table, and the Tiles coffee tables—all designed by Arthur Casas—alongside the Vronka Vintage armchairs by Sérgio Rodrigues and the Ondine armchairs by Jorge Zalszupin. The staircase features artwork by Germana Monte-Mór and a ceramic sculpture by Ediltrudis Nogueira.
In the office, the highlight is the Pan Am sofa (55design), also designed by Arthur Casas, combined with M1 armchairs by Carlos Milan. The dining area is structured around additional pieces designed by Arthur Casas, such as the Lourdes dining table and Disco stools, along with Senior Metal chairs by Jorge Zalszupin, complemented by artworks by Vik Muniz and sculptures by Zé Bezerra. Outdoor areas include Ripas sun loungers and Diretor chairs by Arthur Casas, Loop armchairs by Willy Guhl, and a 19th-century vintage table from Minas Gerais. The breakfast room and children’s area incorporate the Match sofa and Arraia pouf, along with an artwork by Mestre Nicola.
From a technical standpoint, the project incorporates specific technological solutions. The house features lighting automation integrated with natural light sensors, remote control via mobile devices, photovoltaic panels for energy generation, and passive environmental comfort strategies. The landscape design respects the site’s topography and surrounding vegetation, integrating circulation paths and areas of permanence with the architecture, offering a sensitive reading of the terrain and the way greenery structures the spatial experience of the residence.
Grama House synthesizes an architectural approach that combines structural clarity, technical precision, and environmental integration. It is also organized as a continuous system of planes, split levels, and openings, with the cantilevered volume as a key element of architectural expression. The result is a house in which architecture, engineering, and everyday use operate seamlessly, integrating structure, materiality, and environmental comfort, while making the landscape an active element in the organization of interior spaces.
