About this home

A trophy resort-style estate of three separate fully remodeled structures sitting 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.
