Nearly as expansive as its desert surroundings, this massive Paradise Valley estate derives its dramatic design from a majestic Camelback Mountain setting. Spread out among nearly one-and-a-half Arizona acres, the $15.8 million home has more than 16,000 square-feet and every conceivable luxury, addition and amenity. Enormous glass walls pull the horizon into palatial rooms, which are painted to match the warm colors of the landscape. Hand-hewn walnut floors and a hand-carved fireplace add a rustic charm while Sub-Zero and Dacor appliances gleam contemporary convenience. The 7-bed/10-bath stucco home was built in 2008 and has a pair of bathrooms in the master suite, a spa and heated lap pool, media room and guest quarters with a separate exterior entry. [via realtor]
