Pre-purchase opportunity with a target completion in April 2027. Set atop nearly one private acre in prestigious Mount Tiburon, this extraordinary estate property offers panoramic views spanning the San Francisco skyline, Bay Bridge, Golden Gate Bridge, Angel Island, and Mt Tam. Currently undergoing a comprehensive transformation, the existing 3,599-square-foot residence is planned to expand to approximately 4,501 square feet, creating a spectacular contemporary estate designed to maximize the breathtaking setting. The proposed design includes five bedrooms, four full baths, one half bath, soaring living spaces, a luxurious primary suite, private guest accommodations, and seamless indoor-outdoor living. Planned resort-style grounds feature expansive entertaining areas, level lawns, pool, and exceptional privacy. Offered during construction with plans, engineering, and permitting in progress. Rare opportunity to secure one of Tiburon's most compelling future estates. Limited opportunity. Renderings and select images are architectural visualizations intended to illustrate the proposed design. Plans, specifications, and development details are available upon request.
