20th Street Residence Extension by SF-OSL
US-Norwegian architectural practice SF-OSL have designed an extension for an existing family residence in Potrero Hill. The main goal of the project was to gain more space, and to achieve this the only option was to expand up through the roof. The new extension houses kitchen, dining and living areas. A large window facing south provides good ventilation and a flexible sunscreen provides protection from the sun. Take a look at the pictures below.
