Island Passive HouseContemporary Exterior, Seattle
This prefabricated 1,800 square foot Certified Passive House is designed and built by The Artisans Group, located in the rugged central highlands of Shaw Island, in the San Juan Islands. It is the first Certified Passive House in the San Juans, and the fourth in Washington State. The home was built for $330 per square foot, while construction costs for residential projects in the San Juan market often exceed $600 per square foot. Passive House measures did not increase this projects’ cost of construction.
The clients are retired teachers, and desired a low-maintenance, cost-effective, energy-efficient house in which they could age in place; a restful shelter from clutter, stress and over-stimulation. The circular floor plan centers on the prefabricated pod. Radiating from the pod, cabinetry and a minimum of walls defines functions, with a series of sliding and concealable doors providing flexible privacy to the peripheral spaces. The interior palette consists of wind fallen light maple floors, locally made FSC certified cabinets, stainless steel hardware and neutral tiles in black, gray and white. The exterior materials are painted concrete fiberboard lap siding, Ipe wood slats and galvanized metal. The home sits in stunning contrast to its natural environment with no formal landscaping.

What Houzz contributors are saying:
Objection: “Don’t we need to place our foundations below the frost line to keep the finished house from moving?”Solution: Designed properly, a frost-protected slab on grade won’t heave. At about 20 or 30 feet below the earth’s surface, the temperature is fairly constant, between 55 and 60 degrees. Historically in northern climates, we’ve addressed the frost-heave problem by digging deeper than frost can penetrate and placing our foundation footings there.
