About This Home

As of October 2025

Endless Possibilities in Prime Atherton Location! Come see this hidden gem, privately tucked behind secured entry gates and a sweeping semi-circular drive, this rare 0.93-acre estate property delivers both prestige and potential in one of America's most coveted zip codes. The 3,145 SF residence offers 4 bedrooms, 2.5 bathrooms, and 3 fireplaces, along with an attached 2-car garage. Thoughtfully maintained by its longtime owners, the home is move-in ready yet brimming with opportunity to reimagine it for modern luxury. The grounds impress with mature landscaping, in-ground pool and spa, outdoor wet bar, sauna, pool equipment room, and numerous storage sheds. Fully fenced and cross-fenced for ultimate privacy, with dual automatic gates at each end of the drive, convenience and security are built in. Here, the possibilities are endless: update and expand the existing residence, convert the garage to living space, add a 3+ car garage, and/or design an ADU. In a neighborhood where transformed properties command premium value, this is your canvas to create the Atherton estate of your dreams. Don't just buy a home, secure nearly an acre of flat, usable land in the heart of Atherton, where vision and value go hand in hand.
