Completed in June 2016, Unit 12 is the seventh Clearwater Commons home. According to the developers, the Clearwater Commons is an intentional, ecologically-responsible residential community. The project began in June 2006 when a group of families - who were also future homeowners - banded together and purchased the 7.4-acre site on North Creek in Bothell. Wetlands, forest, garden space and a salmon-supporting creek all adjoin the homes onsite. Clearwater Commons ultimately will consist of sixteen single-family homes plus a common area.

The community's design is indicative of its community values and mission of low-impact development. Neighbor interaction is directly facilitated by a design that includes pedestrian walkways, community gardens, benches, shared tool sheds and play spaces. The nearby stream was also carefully restored to act as healthy salmon habitat.

Unit 12, at 1,832 sq. ft., is Clearwater Commons' largest unit.  The home contains three full bedrooms and two bonus rooms and overlooks a large wetland area. Its many green features include recycled products, a Lifebreath Heat Recovery Ventilator, ductless mini-splits, hybrid hot water tank, cork and natural Marmoleum flooring, and PaperStone┬« recycled content counters.
