An all-wood passive solar home factory in Pemberton, British Columbia was named last week as one of 12 winners of the 2016 Governor General’s Medals in Architecture.

The 1,500-square-foot structure, designed by Architect John Hemsworth and made mostly of Douglas fir, “was designed to look like the boxy, prefabricated homes that are made inside it,” CBC reports.

“When B.C. Passive House asked that the design and construction of its new facility reflect its approach to sustainable home construction, the architect took the message to heart,” Canadian Architect explains. “This demonstration project is made with all-wood construction and exemplifies the client’s investment in prefabrication, energy efficiency, and sustainable design. Used for the manufacturing of the client’s prefab Passive House panels, the 1,500-square-metre facility was conceived as a simple, light-filled wooden box.”
