A once-in-a-lifetime opportunity to own a world-class Mediterranean mansion—an ultra-private, resort-style sanctuary in Upper Happy Valley, one of the Bay Area’s most exclusive enclaves. Designed, built, and previously owned by internationally acclaimed artist and designer Henry Conversano—renowned for ultra-luxury resorts, iconic casinos, and bespoke residences for Donald Trump and other elite clientele—this architectural masterpiece blends timeless artistry with modern sophistication. Thoughtfully renovated around the 2000s, it showcases exceptional craftsmanship and museum-quality finishes throughout. Set behind a private gate at the end of a 200-ft driveway on ~3.2 acres, the 8,282± sq ft estate features a dramatic rotunda hall ideal for private galas and intimate gatherings. Polished marble floors flow through the expansive common areas, and picture windows frame breathtaking views of Mt. Diablo, filling the home with natural light. Masterfully landscaped to evoke the elegance of a diamond necklace, the resort-inspired grounds include lush gardens, a 50-ft waterfall, sculpted fountains, a tranquil aviary, outdoor kitchen, fire pit, and multiple terraces for seamless indoor-outdoor living. A rare legacy estate for the most discerning buyer.
