A remarkable, super green prefab home recently installed in Seattle has been making waves throughout the Pacific Northwest and the green building community. It’s a shame that even though I was in the area at the time for the holiday, I didn’t get the chance to check it out (I was too busy shredding).

The 1,790 square-foot home — I mentioned it in a catch up post from a couple weeks back — was developed by Greenfab, a Seattle-based prefab builder that’s also behind a nifty eco-news website. This urban infill project is the company’s first build. HyBrid’s Robert Humble, architect and contractor on the project, is the proud owner of the home. After post-installation work on the home is completed next month, Humble plans to open it to the public as a demo home for a couple of months. After that, he and his wife will move in.

Located in the Jackson Place neighborhood, the $450,000 home is expected to achieve LEED Platinum status, making it the first modular home in Seattle to do so. EnergyStar and Built Green 5-Star certification are also in the works.

Composed of six built-in-Boise modules measuring 12 feet wide, 20 feet long, and 16 feet high, the installation of the home took six hours. The three-bedroom prefab digs boast a ton of green features with a focus on energy-efficiency (it’s designed to be net-zero energy) and water conservation. Among them are a 2.4 kilowatt/hour photovoltaic system, an energy recovery generator, and a 1,400-gallon rainwater cistern, a graywater filtering system, a hybrid heat pump water heater, and, according to the Seattle Times, insulation that reduces energy usage by 50 percent. To top it off, there will apparently be a chicken coop out back and garden boxes on the roof deck for urban farming.


If you’ve never seen a modular home installed in person or on video, the time-lapse videos embedded below are worth checking out (there’s even more where those came from on the Greenfab website). Footage like this never fails to amaze me. And if you’ve never been inside a green prefab abode and live in the Seattle, I’d certainly take advantage of the tours being offered once the project is complete.

To learn more about the home and read some pearls of wisdom about modular building from both the developer and the architect/owner/contractor, head on over to the Seattle Times. The Greenfab media website also offers info and images a plenty.

A big congrats to Humble and the Greenfab team on a successful installation. Next time I’m in town, I’ll be sure to check it out in person — that is, if my shredding schedule allows.
