This cantilevered house, anchored to a rock near Granite Falls, Washington, was designed by the Seattle and San Francisco based firm of architects, Anderson and Anderson. The rock itself is paramount to the design of this prototype of prefabricated structure, by providing a stable foundation for the concrete base without the need to dig down into the ground.

The site and topography made this an ideal opportunity to stress the advantages of prefabricated structures  in terms of versatility, efficiency and cost. The prototype building is constructed of a framework of commercial steel together with structural insulated panels for the walls, roof and floors, leaving openings for picture windows, essential when surrounded by such spectacular mountain scenery. The difficulty of transporting the materials was solved by using logging tracks, an almost impossible task for a conventional building project.

Once the structure was completed, after a period of just a couple of weeks, the owner had his talented artist friends assist him in making it a home. The interior walls are lined with Douglas pine and a pine staircase leads to an upper floor. The landscaping, artwork and simple furnishings complete this mountain home, which is the delight of the owner who states - ‘it really feels like a work of art!’
