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

An urban lot in Seattle’s Jackson Place neighborhood was recently infilled with a super green prefab designed by <a href="http://www.hybridseattle.com/" target="_blank">HyBrid Architecture</a> and built by new prefab maker <a href="http://www.greenfab.com/" target="_blank">Greenfab</a>. Aiming for LEED Platinum certification and net zero energy use, the three story home combines solar power, rainwater collection, urban agriculture and prefab construction. The model home was completed at the end of February and is <a href="http://www.greenfab.com/contact/model-home-events" target="_blank">open for public tours</a> until the end of March.

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.

he home also encourages urban homesteading with a chicken coop, edible landscaping in the yard and garden boxes on the rooftop.

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, then a rain garden and koi pond infiltrate grey water.

Greenfab's aim with their new prefab homes is to offer green and healthy homes 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.

A backup heat panel and the home's energy efficient heat pump.

Plywood flooring.

Inexpensive materials like plywood panels and floors helped keep the price of the home down.
