This article is part of our new "Material Focus" series, which asks architects to elaborate on the thought process behind their material choices and sheds light on the steps required to get a building constructed.

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.
