This an early 1999 green BIM of a tree-unit family owned building in San Pedro, CA. The units are tailored to the requirements of the family members inhabiting the different sections of the building. Rooftop terraces and an overall canopy extend the living area, while material and finishes differentiate the specifics in character. The remodel is also quite budget conscious with the use of industrial corrugated steel cladding and galvanized canopy. The shielded rooftop terrace provides a climate buffer for the lower floors and acts as the major sustainable feature of the homes along with operable skylights at the stairwells.
