10040 E Happy Valley Road 55 One of Desert Highlands' most coveted north-facing golf course lots, backing the first fairway and set against the iconic Pinnacle Peak backdrop. This is the lot discerning buyers have quietly been watching for. On the premier street in Desert Highlands, directly overlooking the first hole of the Jack Nicklaus Signature Course, this 1.85-acre property represents the kind of scale, orientation, and setting that rarely becomes available. North-facing. Golf course edge. Pinnacle Peak as your backdrop. The combination is exceptional. The existing 6, 700 sq ft estate, designed by Vernon D. Swaback, apprentice to Frank Lloyd Wright, was thoughtfully positioned to capture golf course and mountain views from every main living space. That same orientation becomes the foundation for a $7M+ custom legacy estate. Soaring ceilings, walls of glass opening to the desert, a dramatic two-story library, private movie theatre, temperature-controlled four-car garage, and a main-level primary suite with direct access to the heated spa all speak to the scale already in place. The negative edge pool and spa, waterfall, fireplace, built-in BBQ, and boulder-framed outdoor living areas are designed for everyday enjoyment and effortless entertaining. An immediate golf membership is available, granting full access to the Desert Highlands lifestyle: championship golf, tennis, pickleball, a renovated fitness center, clubhouse dining, and 24-hour guard-gated security. The 18-hole putting course is walking distance from the front door. The lifestyle is established. The lot will support your vision.
