Greenfab’s New Prefab Model Home in Seattle Aims for LEED Platinum

The 3 bedroom, 2 3/4 bath home includes non toxic and environmentally friendly materials for good indoor air quality. Recycled and local materials were sourced extensively and existing concrete from the yard was used to create the gabion wall and landscape pavers in the front yard. The home also encourages urban homesteading with a chicken coop, edible landscaping in the yard and garden boxes on the rooftop. A 2.4 kW photovoltaic system on the roof provides 23% of the home’s energy usage, which is already low due to the use of energy efficient appliances, lighting and systems. Rainwater is collected and stored in a cistern for use in water efficient showers and toilets, and a rain garden and koi pond infiltrate grey water.

Greenfab’s aim with their new prefab homes is to offer green and healthy  living to more people at lower prices. Prefabrication of the home took place in a factory outside of Seattle in only two weeks. Meanwhile the site was being excavated and prepped. Once the modular parts arrived, assembly and finish work took only 45 days. All said and done the 1,790 square foot home cost about $180 per square foot to build, not including land costs.

    Are there any planned projects in the SoCal or NorCal area? I would like to experience these design endeavours in person.

    In the article you elude to a few things that were not shown, like the roof, the full bathrooms, the rain collecting systems and the solar array, are there pictures?

    Also, when you mentioned the cost of $180 per sq. ft. did that include the solar system, tankless water heating, the rain collecting cisterns and landscaping…?

    Are there any planned structures in SoCal or NorCal, I would love to see and experience this architecture and building project without having to trek way up to Seattle…

    I find all this utterly fascinating and want to know and learn much more…

    Hi Greenfab, looking forward to that! It’s all about the journey in sustainable design, much more than any set destination. But I think I’m preaching to the choir on this one :) Keep us posted!

    We were pursuing the Living Building Challenge early in the process and even hosted a design charrette to layout a plan for it. Unfortunately budget got in the way for this project. Stay tuned for future projects however, we are envelope pushers! Thanks for the comment.

    Nice. Sort of. Well, as far as it goes I guess. But come on Greenfab: LEED?? Why not leap beyond and truly benefit the community (and grab some market position in the process)? The Living Buildings Challenge, based pretty much in your own backyard, has set the goalposts where they should be: “What if every single act of design and construction made the world a better place? ”

    Don’t get me wrong; LEED is a huge step forward for the building industry, but our understanding of, capability for, and need for more sustainable design and build has already moved beyond “minimizing negative impact”. We have to get focused on maximizing positive impacts. There’s a lot of rebuilding, reconnecting and regeneration needed now, and the Living Buildings Challenge has developed an impressive set of tools, frameworks and other tools to support that. http://bit.ly/9sz2Ld
