Seattle has its fair share of LEED Platinum homes, but this is the first LEED Platinum single-family home in the state of Washington outside of Seattle. The Bainbridge Island home, blending style and sustainability, was designed by Coates Design Architects for owners Ed and JoAnne Ellis, who wanted an exemplary, modern, green home.
It took three years, but now that it’s complete, I think it’s safe to say that the Ellis Residence presents a worthy model for others to follow. The design — combined with geothermal, photovoltaic solar, solar hot water, and advanced heat recovery techniques — reduces energy consumption by 70% compared to a typical home of this size.
Smallwood Design & Construction built Ellis Residence with FSC-certified wood framing and sheathing, as well as a hybrid envelope of closed-cell spray foam and batt insulation. This allowed for a cost-effective approach to insulation performance and air-tight construction, especially when combined with the triple-glazed wood frame windows.
The 2,560 square-foot home is finished with recyclable metal panels, CMU block, and untreated, FSC-certified hardwood in a rainscreen application. The interior trim and stairs are finished with fir trees from the neighbor’s property that were milled on-site. In addition, Ellis residence has a vegetated roof, native landscaping, and rainwater cisterns.
During construction, the contractor diverted 75% of all construction waste and recyclable material from the landfill. Moreover, before any construction began, 98% of an existing cabin and garage on the site was deconstructed and diverted from the landfill. The foundation was ground up and used as structural fill for another project.
Other than LEED Platinum certification, Ellis Residence has been recognized with “Bath of the Year,” according to Seattle Homes & Lifestyles, and an Honorable Mention in the “Design & Build with FSC” 2010 Awards.
