Readers’ Choice 2018 Third Place: Net-Zero Spec House
Despite being a spec project, this house was crafted with careful attention to detail and quality finishes; the main living spaces were kept open and incorporate built-in shelving to minimize the need for furniture.

Despite being a spec project, this house was crafted with careful attention to detail and quality finishes. The main design challenge was the steep topography of the site. The average slope of the lot is 40°, which resulted in a front setback approximately 11 ft. below road elevation. In order for future homeowners to walk into the house without navigating steps and to ensure that there would be access from the lower level to the ground itself rather than to an elevated deck, a bridge was built from the parking area to an entry between the main floor and the upper level. This set the main living area and kitchen about half a floor below the road and parking, resulting in more privacy than if the main floor had been set at street level. The kitchen window and doors look out into garden space rather than the parking area.
The main living spaces were kept open and incorporate built-in shelving to minimize the need for furniture. Interior windows allow light to travel throughout the space. A master suite with a covered porch and one slightly smaller bedroom with its own bath and covered porch are located on the top floor. The lower level is designed to function either as part of the house—providing another bedroom, full bath, rec room, and patio—or as a separate office or rental unit. In order to ensure that the lower level not feel like a basement, the space is designed to be as light and airy as the upper two floors and is finished to the same quality level as the rest of the house. Four covered porches and a patio allow occupants to easily flow between inside and outside. The neighborhood requirement that all homes be net-zero energy and Green Built Homes Platinum-certified influenced many decisions in the construction process, including the use of 2×6 walls with advanced framing and spray-foam insulation and an 8.2kw photovoltaic system on the roof. An airtightness level of 0.58 ACH50 was achieved.

The parking area and the approach to the net-zero house’s front entry and parking area.
The front door is accessed via a bridge from the parking area.
The kitchen island was made of narrow strips of quarter-sawn white oak glued into a 12-ft.-long by 4-ft.-wide board. The waterfall edges are cut so that the grain of each board continues from the horizontal surface down the waterfall sides.
The north side of the house features two cantilevered porches and a long ribbon window at eye level running the length of the house.
