Limits between indoor and outdoor areas blend dynamically in a project in the interior of São Paulo, developed by the Estúdio HAA! Office. The aim was to design a residence with open communication between the outdoor area, maximizing natural lighting and ventilation, and preserving the original topography, thus reducing drastic alterations in the surroundings and minimizing time, cost, and waste during construction, fundamental principles in the development of the office’s projects.

The house was divided into three distinct blocks. The first, called the rigid block, comprises a TV room, kitchen, and powder room on the first floor, while the second floor houses the bedrooms, a shared bathroom, office, and a balcony. To connect the floors, a staircase was designed with custom metal components and steps covered in wood, ensuring safety and stability. Additionally, the lateral protection of the staircase is provided by steel cables that extend to the roof slab.

The second block, called the lightweight block, is intended for the living and dining areas, with the proposal of integration with the lateral garden. Built with a metal structure and glass, this space seeks to unite the internal and external areas. Adjacent to this structure is the master suite, integrated with the outdoor area, meeting the owners’ request for accessibility and comfort, as they wish to enjoy the tranquility of the vegetation and the bedroom without the need to use stairs.
