ABOVE, FACING PAGE TOP, & FACING PAGE RIGHT: Located on Vancouver Lake in Washington, this home presented challenges surrounding the preservation of the site's environment. It was a requirement to protect and
maintain the mature trees, blackberries, and native vegetation. The lot is located on an American Bald Eagle preserve, so there were also noise abatement restrictions to protect the nesting eagles. Because the house was located
on the lake, it has a high water line with a natural meadow in f ront. The flood plain stretches across the site so nearly every room has a glass-wall view of the lake with extended exterior spaces. The entry and great room have a
completely private entry through a berry patch.
FACING PAGE BOTTOM: More than 50 sustainable processes and materials were integrated into the design and it exceeded all Washington State codes. Energy is saved by utilizing a ground-source heat pump for radiant floor
heat and hot water, and a 5.25 kW solar array powers the entire house. Soy-based closed-cell spray-foam insulation, an ICF basement, and a reflective metal roof maintain interior temperatures with minimal energy use. A whole-
house heat recovery ventilator, with humidity and motion sensors, increases heat exchange as necessary. All utilities are underground for safety and aesthetics; the home is visually stimulating, complex, and explorative. This
home won Design and Sustainability awards f rom the AIA and was named Green Builder Magazine's Home of the Year.
