About this home

1135 Galleron is 23.4+/- acres of potential in one of St. Helena's most coveted enclaves. This rare offering includes six legal non-conforming homes dating to 1940, creating an exceptional canvas for multi-generational living, income opportunities, or a reimagined estate compound. One residence, built in 1920 with 2,848 sq. ft., may be relocated and replaced with a main home of any scale, an ADU, pool, tennis court, or an agricultural barn, offering extraordinary freedom to design your Napa Valley retreat. The additional 5 existing homes span a range of sizes, including one at approximately 1,962 sq. ft., three at 1,544 sq. ft. each, and one at 604 sq. ft., built in approximately 1953. Five of the homes must remain in place but may be remodeled within their current footprints. The vineyard, planted in 2000, features approximately 11+/- acres of Sauvignon Blanc, 2+/- acres of Semillon, and 7.6+/- acres of Cabernet Sauvignon. Four of the homes are connected to City of St. Helena water, plus there is a substantial well that serves the property. Galleron Road is known for its quiet prestige, ideal proximity just south of town, and is surrounded by some of St. Helena's most desirable estates. Whether it's the rarity of six homes on one parcel, the promise of an exceptional agricultural setting, or the opportunity to craft a private Wine Country compound, 1135 Galleron invites vision, scale, and imagination.
