    What's special

    Expansive viewsOpen floor planCrisp dove white exteriorSingle-level main home
    Set on 1.48 acres in Sonoma's coveted Diamond A neighborhood, this light-filled 3BD/2BA retreat offers privacy, expansive views, and exceptional indoor-outdoor living. The single-level main home has been newly painted inside and out, featuring a crisp dove white exterior, an open floor plan, and an updated kitchen designed for modern living and entertaining. The living room's large bay window overlooks the hobby vineyard, while expansive windows throughout the home frame the Mayacamas ridgeline and fill the space with natural light. The property features two separate entrances, offering flexibility and privacy. An expansive front yard planted as a hobby vineyard creates a welcoming wine-country approach. Just steps from the main residence, a Tahoe-style detached outbuilding provides an ideal remote office or creative studio. A short walking trail leads to the second outbuilding, a newly constructed hilltop pavilion positioned at the highest point of the property. With wall-to-wall windows and sweeping panoramic views across Sonoma Valley, Napa Valley, San Pablo Bay, and Mt. Diablo, this destination space is perfectly oriented to capture expansive sunrises and early morning light. Private yet just minutes from Sonoma Plaza, this property captures the best of wine-country living and represents a rare combination of acreage, panoramic views, and close proximity to town.
