The house was built for two avid cyclists and has a separate entrance and a lot of bike storage and repair spaces. The upper floors are open and provide stunning views of Lake Washington, while retaining a high level of privacy. Local craftsmen and manufacturers participated in the construction process and provided high-performance window systems, sun screens and locally-sourced building materials.

The house is topped with a butterfly roof that allows of rainwater to be collected in cisterns located on the north side of the building. Efficient insulated concrete formwork creates high thermal mass which retains stabile indoor temperatures, while outdoor mechanical roller shades installed on the west facade minimize solar heat gain.
