The cantilever house is a prototype project to be built near Granite Falls, Washington in the Cascade Mountains North East of Seattle. There is also a second prototype in development for an urban site in San Diego. These projects are part of an exploration of opportunities in prefabricated techniques and modern construction methods. Ideally to develop low cost high quality housing.
Although the building site for this prototype has quite unrestrictive zoning constraints, the challenging topography and geotechnical conditions play a strong role in defining the overall design strategy. The small ground floor building footprint/foundation reduces the cost of this expensive area of the house, and allows the points of attachment to adapt to varying slope and soil conditions.
There are two main systems for this project standardised mass produced building elements, prefabricated steel frames commonly used for inexpensive light weight commercial buildings. As well as SIPS (Structurally Insulated Panel Systems) that provide non glazed building areas. Significant savings are made by using the same low labour intensive structural panels for walls, floors and roof section.
Although the materials and methods of construction are chosen for efficiency and affordability, the underlying design principles guiding the development of the system have the larger goals of producing affordable, high quality buildings that offer variety, adaptability, convertibility, strength, simplicity, spatial richness, and optimized access to views and light.
