It hasn’t been built yet, but a modernistic Passivhaus in Seattle has won a regional architectural award and is being offered for sale for $1.45 million.
In a joint announcement, Hammer & Hand builders and Heliotrope Architects said the 3,000-sq. ft. house would be built to Passivhaus standards. The three-bedroom, two-bath house will cost about $483 per sq. ft., not including transactions costs.
The house won a Northwest and Pacific Region Design Award from the American Institute of Architects in 2011, said Zack Semke, director of business development for Hammer & Hand.
One factor driving up the cost is the lot, Semke said, which is located in a pricey Seattle neighborhood near Green Lake. The lot, measuring a fraction of an acre, is “very desirable,” he said, and will have views of the lake.
“Our aim was to combine design excellence with cutting-edge building science to prove that sustainable homes can be beautiful, and that high design homes can be sustainable,” Heliotrope principal Joe Herrin said in a news release. “It’s a combination not often seen in our region.”
Passivhaus spec projects starting to crop up
Passivhaus construction is a relatively new development in the U.S. Compared to the hundreds of thousands of conventional homes built each year, the number of projects certified through Passive House Institute U.S. or Germany’s Passivhaus Institut is minuscule.
But Passivhaus spec projects are beginning to show up. Earlier this year, a duplex in Portland, Ore., was immediately snapped up by buyers. In Philadelphia, Onion Flats and Domani Developers are behind a 27-unit townhouse project built to the Passivhaus standard. Three units have been completed to date; two of them have been sold.
