Invisible House

Perched on a ridge in Australia's Blue Mountains, the Invisible House uses generous amounts of glazing to take advantage of its elevated setting. The concrete, glass, and steel exterior is protected by a massive cantilever roof that serves as both a thermal device and dam, reflecting sunlight off the water, lending to the home's covert namesake. Internally, the space maintains a palette of concrete, Mudgee stack stone, brass, and copper, while each of the four bedrooms are lined in plywood. Thanks to expansive openings in the east-facing walls, the Megalong Valley is on full display from nearly every inch of the interior.
