Emphasizing craftsmanship and natural materials, Obsidian residences present stylish comfort and beauty through the sophisticated use of timbers, glass, and hand cut stone.

The Clubhouse provides amenities that include an indoor heated swimming pool, adjacent spa, a fireplace lounge, large complimentary owner storage, residence services area, a fitness center and a full kitchen equipped to cater events.
