RR House, a summer residence by Andrade Morettin Arquitetos Associados on the northern coast of São Paulo, utilizes a large protective “shell” to house the program, shielding it from sun and rain while enabling cross ventilation. The six-meter-high roof, constructed with a wooden structure and galvanized steel joints, covers the space. Fiberglass and PVC screen panels on steel frames create an external membrane, preserving views and sea breezes while blocking insects. Elevated on concrete stilts, the construction system allows for quick assembly, minimal waste, and reduced environmental impact.
This summer residence is situated just a few meters from the sea on the northern coast of São Paulo, an area known for its lush vegetation and hot, humid climate.
The project began by creating a large shelter, or “shell,” to protect the structure from the intense sun and frequent rains, while still facilitating permanent cross ventilation.
This shell consists of a six-meter-high roof with an 18-by-8-meter base, built using a wooden structure with galvanized steel joints. The roof’s top and side closures are composed of steel tiles filled with EPS (expanded polystyrene).
The two largest facades of the house, which are open to the surrounding landscape, feature fiberglass and PVC screen panels mounted on pivoting or sliding steel frames. This external membrane was designed to keep insects out without obstructing the views or the flow of the sea breeze.
The entire structure is elevated 75 cm above the ground, supported by concrete stilts cast on-site. All other building components were prefabricated and assembled on-site.
This construction system not only allowed for quick and precise assembly but also ensured a dry worksite, minimizing waste and reducing environmental impact.
