In British Columbia’s Soo Valley, only some 20 minutes from Whistler skiing, this off-grid residence designed by Perkins & Will is a pilot for Delta Land Development’s future alpine settlement. Principally powered by the sun, it’s built to Passive House standards, collecting its own water and treating its own waste. Heated by a GeoExchange geothermal pump, it also embraces natural ventilation with cleverly placed windows.
