A Napa Valley estate of extraordinary scale and beauty. Set on 100 acres with 2 legal parcels just minutes from the Silverado Trail in St. Helena, this remarkable private compound unfolds above Lake Hennessey with sweeping water and vineyard views, exceptional privacy, and an extraordinary collection of residences and amenities. At the heart of the estate is a newly remodeled 8,500 sq. ft. residence, where refined architecture meets relaxed Wine Country living. Four bedrooms, four full and two half baths are complemented by two private offices, a sun-filled solarium dining room, wine cellar, chef's kitchen, and expansive pantry. Venetian plaster walls, floor-to-ceiling Chinkapin oak pocket doors, custom ironwork, walnut hardwood and French limestone floors bring warmth and sophistication throughout. An infinity-edge pool seemingly disappears into the lake beyond, while two detached guest houses approximately 1,000 enjoy their own 60-foot lap pool. Beyond the residences, mature gardens and fountains frame a series of intimate and grand entertaining spaces. A full-size tennis court, bocce court, approximately one acre of coveted Pritchard Hill Cabernet vines, and spectacular Lake Hennessey views complete this one-of-a-kind Napa Valley retreat. Private, timeless and virtually impossible to replicate.
