Details
The 1,950 square foot, 3-bedroom, 2.5-bathroom home is positioned on a knoll above protected wetlands, northeast of Bellingham. Not only is it surrounded by 9.88 acres of undisturbed land and preserved native trees, but the owners also planted an additional 1,000+ native trees and shrubs to maintain the natural ecosystem on their beautiful remote lot. House in a Hollow was built with a Department of Energy certified Net Zero design and an aging-in-place floorplan. These certifications mean that House in a Hollow only uses as much energy that it produces through installed solar, and the aging-in-place floorplan supports the environment allowing the residents to live within the home for as long as possible. It is also Built Green 5-star certified, ENERGY STAR® Homes Northwest certified, and EPA Indoor airPLUS® certified. This means that House in a Hollow is 30% more energy efficient than the current WA State Code and installed Solar PVS, and it meets the energy performance and indoor air quality standards set by the EPA. House in a Hollow was made to reduce greenhouse gas emissions and ensure a safe and healthy home during smokey summers.
