Set on approximately 1.45 level acres in the heart of west Atherton, this exceptional estate blends historic pedigree with modern livability. Extensively renovated and expanded in 2001, the residence reflects timeless architecture with the scale and amenities expected in one of Silicon Valley's most sought-after neighborhoods. The home, defined by grand proportions, spans over 12,000 livable square feet across three levels plus a guest house. Signature elements include carved stone fireplaces, arched windows and a series of formal and casual spaces designed for both entertaining and everyday living. Amenities are extensive: a luxurious primary suite with dual dressing rooms, steam room and gym; a wine cellar with tasting room; a 10-seat theater; library and billiards room with bar; and a rare 12-car underground garage of over 3,700 square feet finished to a showroom standard. The property includes six bedroom suites in the main residence, along with a two-bedroom guest house with office, ideal for extended stays or multigenerational living. Resort-style grounds feature a pool, spa, outdoor kitchen, rose garden and expansive lawns framed by mature trees. Located close to top private schools, Stanford, Sand Hill & Hwy 280, this is a rare opportunity in a premier Atherton setting.
