Description

An extraordinary, legacy Mediterranean estate commanding panoramic views over the Sonoma Valley. Privately approached through a dramatic double-gated entry lined with manicured hedges and stately cypress, this rare offering blends architectural presence, privacy, and elevated wine-country living. The main residence spans approximately 4,400+ sq ft with 3 bedrooms and 2.5 baths, complemented by a separate 1-bedroom, 1-bath guesthouse. A detached 7-car garage carriage house with game room and additional guest quarters above offers exceptional flexibility for hosting, recreation, or multi-generational use. Designed to embrace its setting, expansive terraces and an infinity-edge pool frame sweeping Valley of the Moon vistas. Distinctive amenities include a private indoor gun range and a Generac whole-property backup power system, ensuring both discretion and resilience. A hobby vineyard with on-site winemaking facilities completes the estate. Two solar systems support the property, including solar pool heating. Utterly private, yet moments from the Sonoma Plazaan heirloom-quality estate of remarkable rarity in Sonoma Valley.
