Perched above Lake Washington, this compact Renton residence combines a variety of structure types including insulated concrete formed walls, an exposed steel moment frame, and curtain walls over a metal pan deck with concrete topping (typically used in commercial applications). Sustainable features include a pervious concrete driveway, radiant floor heating, super-efficient insulated concrete formwork and a rainwater collection system. With solar power as the main heating system, the roof design features an unusual configuration that allows the photovoltaic panels to be inconspicuous. The constraints of this compact site combined with a unique combination of exposed structural systems and an extensive use of materials contributed to the “fun factor” of the engineering for this home.
