A trophy resort-style estate of three separate fully remodeled three structures, sitting on two parcels of approximately 1.69 level, usable acres on Round Hill in the Bel Aire neighborhood of Belvedere Tiburon: a 7,489 sqft main residence, a detached two-story guest house, and a pool house. The main residence places the entire main living level on one continuous floor, with San Francisco skyline, Golden Gate Bridge, and Bay Bridge views from the main living spaces and additional bedrooms below. Across the compound, ten rooms of flexible accommodation as suites, staff quarters, gym, office, or media room, nine bedrooms and six full baths and a half bath in the main house, plus more than 8,000 sqft of total living space, suited to multi-generational living within a single-family estate. Guest house, approximately 1,200 sqft, remodeled in 2023 with new HVAC and its own unobstructed San Francisco skyline and Golden Gate Bridge views. Tennis court, pool, spa, and pool house on level lawns: a built-in staycation. Six-car garage plus four-car carport for ten covered spaces, with generous guest parking. The second parcel provides lasting privacy and view protection. Minutes to downtown Tiburon and the Tiburon ferry, within the Reed Union School District.
Property is new construction or fully renovated.
This trophy estate consists of three fully remodeled structures. The guest house was specifically updated in 2023 with new HVAC systems, and the entire property is described as a resort-style compound in mint condition, meeting the criteria for a comprehensive renovation within the last 5 years.
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 44400, living area = 7489.
The estate offers world-class, unobstructed views of the San Francisco skyline, Golden Gate Bridge, and Bay Bridge from both the main residence and the newly remodeled guest house.
Spanning 1.69 level and usable acres across two parcels, this property is a rare find in Tiburon, featuring a tennis court, pool, spa, and expansive lawns that create a private resort-style atmosphere.
The scale of the 1.69-acre grounds, multiple detached structures, and extensive amenities like the pool and tennis court will require significant and costly ongoing professional maintenance.
Despite extensive remodeling, the original 1968 construction may still possess certain structural or layout limitations compared to a ground-up contemporary build in this ultra-luxury price bracket.
