About this home
Lot
Build Your Napa Valley home, opportunity to craft the wine country retreat you've always envisioned. This nearly half-acre parcel sits just three miles from the coveted heart of downtown St. Helena, placing world-class dining, boutique shopping, acclaimed wineries and schools within minutes of your front door. The land is ready to work with you: an existing well and septic plan has been started, with reports available. A peaceful seasonal stream graces the rear of the property, adding a natural, serene boundary. Building plans were in process with Napa County for a thoughtfully designed two-story home featuring a garage with an ADU guest suite above, maximizing every inch of the parcel to create both generous living space and income or hosting potential. Whether you're dreaming of a full-time residence, a wine country escape, or a legacy property to pass down, this is your canvas.
