11 Carraig Ridge is 3.76 acres sloping south from 1,352 to 1,328 metres and is designated for an Edge Retreat. This lot has an initial concept by Olson Kundig, designed to be low maintenance, adaptable to the changing needs of future generations, and extremely energy efficient. The home design meets the German Passivehouse standard for energy performance, the world’s most progressive energy standard, by employing digital environmental models to predict performance. The predicted energy use of the building is 4kbtu/yrsf – 90% less than typical housing stock in Canada.

Access to 11 Carraig Ridge is from the drive at the north edge of the lot. Passing through a grove of aspen, the retreat is located at the tree line along the ridge with primary views to the south of Ghost Lake and the mountains of Kananaskis across the Bow valley. At the southern edge of the lot is a walking path extending north and south through Carraig Ridge. The slope opposite the walking path is covered with aspen and spruce, is frequented by deer and the occasional mule deer and is a seasonal elk migration route. Hawks, bald eagles and golden eagles are often seen riding the thermals overhead.
