The House in Lago Sur Qi 25 was designed by Sérgio Parada Arquitetos Associados firm. The project is 800 square meters and the layout is organized into 3 floors. Their volumes were defined by their use: intimate, service, formal and leisure. The project’s structure is completely made up of reinforced concrete with large openings that allow for complete integration of the exterior with the interior. We talked with the architect Rodrigo Biavati to learn more about the material choices and challenges of the project.
