To take advantage of the stunning viewpoint, we constructed a significant retaining wall for the Arches. The reward is a mountain view that is one of the best in Calgary, and a view of the Arches that is breathtaking. The massive cantilevered steel beams you can see anchored to the paper face concrete wall support the upper stories and decks. Arches also features hydronic heating, an indoor pool and state-of-the-art golf simulator.
