Perched atop the prestigious Dominican neighborhood in Marin County is the famed estate of 1 Highland Avenue. This one-of-a-kind compound -- originally built in 1904 -- blends historic charm and class of a by-gone era with modern sophistication and finishes. Completely restored circa 2025, the grand home encompasses over 8,000 square feet and extends over 3 acres of private, manicured grounds. Once the residence of a legendary professional tennis coach who trained former World No. 1 players, the estate boasts a professional-grade tennis court, complete with lights, a rare gem that was once the training ground of some of the greatest tennis players in history. The main residence features five bedrooms, including a fully equipped au pair suite, and 4.5 bathrooms. The home boasts the highest quality finishes, adorned with gorgeous wood paneling and open beam ceilings, walnut floors, expansive panoramic windows, a full gym, and spa complex with a traditional and infrared sauna and steam room. The open kitchen is the heart of the home, with top of the line appliances, from the La Cornue range, to the Gaggineau refrigerators. No expense has been spared when it comes to this home. This is a fully gated sanctuary offering unparalleled privacy and space, yet just 23 minutes away from SF.
