About This Home
Rare New Construction — Design Your Dream Estate Before It's Built The one opportunity buyers almost never get: a fully envisioned luxury estate you can still make entirely your own. Set on an expansive 22,600 SF lot — over half an acre — this to-be-built residence offers 7,409 SF of living space with 7 bedrooms and 7.5 baths, thoughtfully composed across a 3,709 SF main house, a spectacular 2,500 SF finished lower level, and a detached ADU. A private elevator connects every level. A lower level unlike anything else. With soaring 11-foot ceilings and light wells that flood the space with natural light, the lower level redefines home entertainment around wellness and rejuvenation: a home theater, lounge, gym, sauna, and wine bar — your private resort, one floor down. Room for everyone — and everything. A detached 1,200 SF ADU with 2 bedrooms and 2 full baths welcomes guests and extended family, or generates rental income. A 900 SF three-car garage and a 40' × 20' pool complete the estate. Make it yours — truly yours. Through December 1, 2026, the design can be customized — or completely reimagined — giving you what buyers in this market almost never find: the chance to shape a home of this caliber from the ground up. Your finishes, your floor plan, your vision. Estimated completion: September 2028. Buy the finished spec house in 2028, and you'll pay a premium for someone else's choices — and compete with every other buyer to do it. Secure this today, and the home that gets built is the one you imagined, at today's price. Over half an acre of possibility. A stunning vision already in place. A rare invitation to make it yours. Your home will be designed by one of the Peninsula's most sought-after residential designers. Our architect has designed more than twenty homes in Atherton alone, along with residences for many of Silicon Valley's leading technology executives and prominent families. His gift is a simple one: listening to how a family truly wants to live, and transforming that dream into reality. Over the course of more than four decades, he has designed and entitled well over 2,000 high-end residential projects, a portfolio that collectively has grossed in excess of $6 billion in sales. His work has been featured in national and several regional publications, including the Associated Press, USA Today, Architect/Builder Magazine, Gentry Magazine, and the San Jose Mercury News. His clientele spans a distinguished range of homeowners, contractors, professional athletes, business owners, and upper-level executives of Fortune 1000 companies.
