Rare Napa Valley estate on 1.29 acres, under construction with $400K+ already invested and existing contractor mobilized for rapid completion. Buyer walks in with instant equity—asking $4.7M vs appraised $5.6M; projected ARV $8.375M. Shovel-ready contemporary compound features a 4,049 sf main residence and 406 sf guest house designed for seamless indoor/outdoor living: vaulted ceilings, floor-to-ceiling glass, reclaimed natural wood, stone accents, and handcrafted tile. Also includes a 1,377 sf detached garage and a 1,000 sf outdoor kitchen with climate-controlled wine room. Landscaped grounds offer a sculptural entry court, kidney-shaped pool, multi-use putting green/lawn, mature privacy plantings, and sweeping vineyard and estate views. Sold as-is; completion requires approximately $1.4M. Sustainable infrastructure is integrated with durable materials and efficient systems. Ideal for an investor, builder/developer, or build-to-suite end buyer seeking fast execution, dual lifestyle/income potential, and trophy wine-country distinction with easy access to Napa’s tasting corridor and regional transport.
