Tucked at the end of a quiet cul-de-sac on approximately 2 private acres, The Koshland Estate is a once-in-a-lifetime offering in one of the Peninsulas most prestigious enclaves. Designed in 1961 by Frank Lloyd Wright disciple Howard Friedman for his father-in-law, Levi Strauss & Co. President and CEO Daniel Koshland, the home was constructed to exceptional commercial-grade standards, rarely seen in residential design. This approx. 8,000 square foot home offers 6 bedrooms, 4 full baths, and 2 half baths, all thoughtfully arranged within a layout that blends timeless design with grand-scale living. Positioned on a broad, level lot, the estate captures sweeping 200° views from San Francisco to San Jose, showcasing city skylines, iconic bridges, and the full expanse of the Bay Area. The Koshland Estate delivers an extraordinary combination of privacy, accessibility, and world-class vistas. A true Peninsula icon.
