40555 Sand Dune RD Rancho Mirage, CA 92270

With sensational mountain and golf course views from its privately gated 3-acre setting within Rancho Mirage's storied and prestigious Thunderbird Country Club, this legendary Mid-Century Modern masterpiece presents a once-in-lifetime opportunity. Built for Belgian Ambassador Leonard Firestone of Firestone Tires, the sprawling Firestone Estate melds walls of glass, steel-beam construction and appreciated privacy into a sublime setting. The residence has been faithfully and painstakingly restored inside and out to showcase the talents of renowned architect William Pereira, whose portfolio includes the futuristic Theme Building at LAX and San Francisco's Transamerica Pyramid. With 5 bedrooms and 6.5 baths in nearly 7,280 square feet, the open and airy single-level design displays frameless floor-to-ceiling windows, walls of slide-away glass, luxurious guest accommodations, and an impressive entrance with glass and metal doors. A private courtyard encourages fun and relaxation with a pool and spa, a reflecting pool amplifies the beauty of fairway and San Jacinto Mountain vistas, and the tennis court welcomes memorable matches.
