Sustainable Products, Projects and Green Design Out Of Sight Sustainable Social Building by Luan Fontes Out Of Sight is a social building project designed for Friars Island in Rio de Janeiro, Brazil. The project uses forty two twenty foot shipping containers treated with thermal insulation, forming a built area of 620 square metres. The containers house a dance school that previously operated beside the neighbouring church and three emergency social homes for local residents. A steel structural system was chosen to keep the construction light, safe and quick to build. The design follows the existing topography and supports access to culture and decent housing.
