Set on an impressive nearly 28,000-square-foot lot (.63 acres) in the prestigious lower section of Mandeville Canyon, 1639 Mandeville Canyon Road offers an extraordinary opportunity to reimagine or build new within one of Brentwood's most coveted enclaves. Tucked beyond a long drive and positioned well off the street, the property unfolds into a tranquil, park-like setting -- defined by open skies, mature trees, and exceptional privacy. The existing single-story residence spans approximately 3,954 square feet, including a 402-square-foot guest house, and is embraced by lush landscaping and expansive stretches of manicured lawn. At the rear of the property, a sparkling pool anchors the generous grounds, providing a natural centerpiece for future resort-style outdoor living. With rare flat terrain, expansive dimensions, and distinct seclusion, the lot offers developers and end-users alike the flexibility to restore, expand, or build a bespoke estate from the ground up. The scale and serenity of the setting make it a compelling canvas for a world-class residence that maximizes both indoor and outdoor living. Ideally located just minutes from the heart of Brentwood yet quietly removed from the city's pace, 1639 Mandeville Canyon Road represents a truly rare opportunity to craft a legacy estate in a setting that offers both prestige and possibility.
