A Rare Sonoma County Legacy: The Pinnacle of Alexander Valley Offered for only the third time in its modern history, this 308-acre ranch represents one of the most significant and beautiful land holdings in Sonoma County. A true legacy property, it offers a rare combination of absolute privacy, uncompromised panoramic views of the Alexander Valley, and a diverse natural landscape featuring rolling hills, a meandering stream, a private pond, and stands of majestic old-growth oaks. The estate is perfectly positioned for immediate development. The foundation is complete for a sprawling 7,742-square-foot main residence, with comprehensive architectural plans from 2019 included. This provides a unique advantage for the visionary buyer to bypass years of site preparation and move directly into the construction of a world-class showplace. Complementing the primary homesite is a newly renovated, 3-bedroom, 2-bathroom guest house. Finished with luxurious modern touches, it serves as an ideal full-time residence while the main estate is completed. For the viticulturist, the property offers 10 acres of premium plantable vineyard land, with an additional 40 acres of grassland suitable for conversion. This is more than a ranch; it is a private sanctuary and a generational investment in the heart of Wine Country.
