An extraordinary value for a home of this scale and significance offering over 9,600 square feet of architectural brilliance, soaring ceilings, dramatic entertaining spaces, one-of-a-kind pool/spa, views, and complete privacy behind gates. A true architectural landmark, this one-of-a-kind Bel Air estate, the "Ursa Major" is both a piece of history and a work of art. Originally conceived by renowned AIA architect David Rich and inspired by FAIA Frank Lloyd Wright, this estate was custom built for basketball legend Wilt Chamberlain ("The Big Dipper"). Perched atop a secluded 2.5-acre promontory at the end of a quiet cul-de-sac with only nine other homes, this serene neighborhood is immersed in nature and surrounded by soaring eucalyptus trees and sweeping canyon views, offering a sense of peace rarely found in Los Angeles. With absolute privacy behind massive gates, views include city and valley views, Stone Canyon Reservoir and all the way to Long Beach on clear day. Recent renovations were carefully considered to blend luxurious materials while preserving its bold architectural soul, including soaring volumes, organic geometry, five-story great room with cathedral ceilings, tree-like columns, walls of glass and signature Bouquet Canyon stonework. Layout includes a massive primary retreat with his and her baths and closets with city views, media room, guest-maid quarters, guest room with separate access, billiard lounge, redwood sauna, outdoor kitchen and expansive indoor-outdoor entertainment areas surrounded by lush gardens including a look-out point and fig, orange and lemon trees. At the heart of the property lies one of the most extraordinary residential pools in Los Angeles - a natural-style body of water that wraps around the home and even allows you to swim directly from the outdoors into the main residence - a feature impossible to replicate under today's building codes. A grand motor court and three garages accommodate 10+ vehicles, while an additional climate-controlled detached structure provides ample storage. A celebration of visionary design, privacy, and natural beauty, this estate stands as a living testament to timeless architecture and the enduring spirit of its legendary creator. Truly an "Architectural Wonder" and a must-see for discerning buyers who value privacy, artistry, and history in one of Bel Air's most prestigious enclaves. Ideally located between Van Nuys and Burbank Airport for jetsetters and private travel. Seller will consider cryptocurrency as a form of payment.
