A once-in-a-lifetime opportunity to own a world-class resort-style Mediterranean mansion—a luxurious and ultra-private sanctuary tucked within Upper Happy Valley, one of the most exclusive and coveted enclaves in the San Francisco Bay Area. Designed, owned, and built by internationally acclaimed artist and designer Henry Conversano, renowned for his work on ultra-luxury resorts, iconic casinos, and bespoke residences, this architectural jewel is a true expression of legacy, artistry, and refinement. Thoughtfully renovated around the 2000s, the estate seamlessly blends old-world craftsmanship with modern sophistication. Privately situated at the end of a gated 200-foot driveway on approximately 3.2 acres, the estate spans ~8,282± sq ft of meticulously crafted living space. Polished marble floors flow through the grand common areas, and every finish has been hand-selected. At its center is a dramatic grand entertainment hall, ideal for hosting formal galas, private performances, or intimate gatherings on a spectacular scale. Picture windows capture Mt. Diablo views, filling the home with natural light and scenic beauty. A ~1,114± sq ft guest house and resort-style grounds with a 50-foot waterfall, fountains, aviary, and outdoor kitchen offer luxurious indoor-outdoor living.
