Cascade Built just announced a new single-family home in the Madison Valley neighborhood of Seattle, Washington.  “Alley House 2” was designed by Seattle-based David Foster Architects and is currently under construction by Method Homes in an off-site factory.  The project team is seeking LEED Platinum certification with completion set for about October 2011.

Located near the original Alley House (which was constructed by Cascade Built), this contemporary home gets its name from being on an infill lot with alley access.

The green prefab is pre-selling, according to a listing with Infinite Real Estate and Development, for $599,000.  That includes a 1,687 square-foot home with three bedrooms, two bathrooms, and a one-car garage.

Alley House 2 will have advanced framing, ample natural light, solar hot water, hydronic in-floor heat, on-demand hot water, zero- and low-VOC finishes, strand bamboo flooring, rainscreen siding, pervious paving, drought-tolerant plantings, and a roof ready for vegetation and solar PV.
