This Camelback Mountain estate in the Phoenix-Scottsdale area offers mountain and city views. No wonder, because it’s on Wonderview Road, next door to The Phoenician luxury resort. But at 21,000 square feet — plus a massive glimmering chandelier in its grand entry hall and a dramatic column-flanked front entry — this house could be a resort itself. The mansion has three fireplaces, including one in the master bedroom; many terraces; and, out on the 1-acre grounds: a heated swimming pool, hot tub and eight-car garage.
