The Westford Habitat House is a 1,400 square foot single-family home located in Westford, Massachusetts. Built into an existing community, the three bedroom, two bath house features a front porch that serves to shade dining and living room windows as well as to provide a space for outdoor living. Large overhangs limit direct solar gain through the high performance windows during the summer and welcome solar gain in the winter. Rainwater and snowmelt from the roof drain off the overhang into a gravel drainage system that daylights at the rear of the site.
Architect of Record
Part of the Cleveland EcoVillage project, the two 1,800 square foot single-family GreenBuilt homes are built into an existing community in Cleveland’s Ohio City neighborhood. By combining architecture and engineering, these infill homes are energy-efficient, accessible and affordable. The main living space along with bedroom and bath are located on the first floor with two additional bedrooms, bath and loft space on the second floor. Covered front porches provide outdoor living space as well as limiting direct sunlight into the living room, decreasing solar gain in the summer.
