About This Home

Designed for both relaxed living and large-scale entertaining, the property features expansive indoor-outdoor spaces, a resort-style pool and spa, a major outdoor kitchen pavilion, and a dedicated catering kitchen, all surrounded by curated gardens, lawns, and vineyard views. Approximately 15 acres of planted vines, including Sauvignon Blanc, Cabernet, and Petite Verdeaux, provide both beauty and potential income, while modern infrastructure such as solar power, multiple wells, advanced irrigation systems, and a Control4 smart home platform ensures seamless operation. With its blend of lifestyle amenities, agricultural value, and turnkey functionality, the estate presents a compelling opportunity for a full-time residence, weekend retreat, or legacy Napa Valley compound.
