An Extraordinary Opportunity at an Incredible New Price! Privately set behind custom-designed gates in historic Sobre Vista Estates, this one-of-a-kind 2.26 acre estate blends classic mid-century modern architecture with sophisticated contemporary design and resort-caliber amenities.

Ideal for grand entertaining or intimate gatherings, the home offers an impressive great room, formal dining, billiards room, family room, and state-of-the-art gym. The gourmet kitchen with high-end appliances is the perfect blend of form and function. 7 ensuite bedrooms each open to a private terrace. A 60-ft saltwater pool with fire feature anchors the outdoor entertaining space, alongside a full kitchen, and limestone terraces. Recreational amenities include a private tennis court, bocce, croquet, volleyball courts, and geothermal soaking tubs fed by a 1000 ft deep geothermal well. The magnificent Penney Magrane-designed grounds boast a heirloom fruit orchard. Minutes to world-class wineries and Sonoma's downtown plaza & just 50 +/- minutes to SF.
