18350 Arnold Drive

Tucked behind mature landscaping just minutes from Sonoma Plaza, Arnold Estate is a beautifully reimagined Wine Country retreat offering a rare combination of turnkey design, expansive outdoor living and a fully independent guest cottage. Set on more than a quarter acre, the property unfolds as a private Sonoma sanctuary, with a renovated main residence, detached cottage, lush gardens and multiple spaces designed for gathering, dining and relaxing outdoors. Inside, vaulted ceilings and exposed beams bring warmth and character to the light-filled main residence. The open kitchen and living spaces have been thoughtfully updated with elevated finishes while retaining the relaxed character that makes Sonoma living so special. The separate cottage creates exceptional flexibility for visiting family and friends, a private office or additional living space, with its own entrance, bedroom, living room, kitchen, dining area and full bath. Outside, mature trees frame a series of inviting spaces: dine beneath the open sky, gather around the fire pit, unwind in the hot tub or spend long afternoons on the lawn surrounded by established gardens. Beautifully renovated, remarkably versatile and ready to enjoy from day one, Arnold Estate offers the increasingly rare opportunity to own a private Wine Country retreat just minutes from the restaurants, tasting rooms and energy of downtown Sonoma.
