The Cantilever House (built in the Cascade Mountains near Granite Falls in Washinton State) is a prototype installation that explores prefabricated construction techniques.

Anderson Anderson Architecture designed the residential structure and combined a prefabricated steel structural frame with a structural insulated panel system (SIPS) to envelope all of the non-glass areas. The Cantilever House is the first of a series of projects to explore the efficiency and affordability of this construction method. A second prototype is planned for an urban San Diego site.
