Grama House by Arthur Casas
Grama House is a single-family residence in Itupeva, Brazil, by Arthur Casas. Conceived for a couple and their three children, the 2025 house uses split levels, strong cross ventilation, and broad openings to keep daily life tied to the site’s gentle slope and outdoor views.
About Grama House
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. The house is organized around ventilation, natural light, and a close relationship with the outdoors, shaped by the site’s gentle slope and a corner lot free from neighboring visual interference.
The architectural concept concentrates the plan on the ground plane and breaks it into split levels, allowing the house to spread across the terrain while keeping constant contact with the exterior. Multiple openings bring in light and air, often moderated by motorized brise-soleils that soften sun exposure and support thermal and visual comfort. Cross ventilation and daylight guide both the layout and the way the site is read.
Programmatically, the house unfolds over two floors with a fluid sequence between rooms. The ground level holds the social entrance, garages, including one for the homeowner’s vehicle collection, and service areas. Upstairs, the main living areas are divided into two levels: the lower level contains the living room, dining room, kitchen, gourmet area, and swimming pool, while the upper level contains the suites and a pilates room.
The office takes a singular position in the composition. It projects 11 meters over the social entrance and also serves as the roof of the porte-cochère, making it the project’s defining structural move. That gesture requires steel trusses anchored into 50 x 50 cm columns, with the greatest live load concentrated at the far end where fixed millwork is placed, demanding precision in both structure and detailing.
Material continuity links the interior and exterior. Rough stone, plaster, wood, and metal shape the façade, while the interior uses wood panels, textured paint, and the same stone-and-plaster system found outside. The result is a clear continuity between construction and atmosphere, one that balances solidity with everyday comfort.
Inside, the furnishing plan follows the same logic. The living room brings together Arthur Casas pieces such as the Rest and Ela sofas, the Mistral side table, and the Tiles coffee tables, alongside Vronka Vintage armchairs by Sérgio Rodrigues and Ondine armchairs by Jorge Zalszupin. The staircase is marked by artwork by Germana Monte-Mór and a ceramic sculpture by Ediltrudis Nogueira.
The office centers on the Pan Am sofa by Arthur Casas for 55design, paired with M1 armchairs by Carlos Milan. In the dining area, the Lourdes table and Disco stools join Senior Metal chairs by Jorge Zalszupin, while works by Vik Muniz and sculptures by Zé Bezerra add a strong art presence. Outdoors, Ripas sun loungers, Diretor chairs, Loop armchairs, and a 19th-century table from Minas Gerais extend the same material register into the landscape, while the breakfast room and children’s area use the Match sofa, Arraia pouf, and an artwork by Mestre Nicola.
Technical systems reinforce the house’s environmental agenda. Lighting automation works with natural light sensors, remote control is available by mobile device, and photovoltaic panels generate energy. The landscape respects the topography and existing vegetation, threading circulation paths and places to linger through the terrain so greenery remains part of the spatial experience.
