The design challenge for this new hotel resort was to create a distinctly Southwestern luxury destination harmonious with its landmark 130-acre setting along the southern flanks of Camelback Mountain, in Arizona. The 474 guestrooms of the main hotel are incorporated within the sweeping arcs of two mid-rise buildings which back up against the imposing mountain, with bold forms that echo the nature of stone and the landscape of the mountain. Shear walls stagger at the end buildings imitating ragged rock, while guest room terraces slope back to offer full exposure to the sun.

The arc of the main hotel is completed as a full circle with the massing of 131 lower casitas, spa facilities, and restaurants. The garden oasis thus created is furnished with tiered waterfalls and lavish swimming pools. Although the plan dimensions of the circular buildings are monumental, in keeping with the mountain setting, the character and scale of the enclosed oasis is decidedly residential.
