“Hillside House” was designed for the Developer with the intent of being a spec home in the unincorporated area of Topanga Canyon. Steeply sloping terrain, Coastal Zoning requirements and site accessibility provide considerable constraints for development in the area. As a result, this design relies a modular prefabricated insulated panel system. Prefabricated panels are built in a factory controlled environment, and delivered to the site for simple assembly and button up.
