Property Description
Five minutes from Meadowood Resort and the heart of St. Helena, this 20-acre estate is a rare find private, polished, and completely turnkey. The single-story +/- 2,979 main residence has been thoughtfully remodeled, with three ensuite bedrooms, a dedicated office, a chef's kitchen, and generous dining all opening seamlessly to the outdoors. A self-contained guest cottage with full kitchen and living room offers flexibility for visitors or extended family. Beyond the residence, the property unfolds into a world of its own: a wine cellar and tasting room, bocce court, outdoor BBQ pavilion, raised garden beds, an olive grove, and mature landscaping framing it all. A year-round creek edges the property, lending a peaceful rhythm to the setting. Whether as a full-time sanctuary or a weekend retreat, this estate delivers effortless Napa Valley living at its finest.
