Napa Valley Water Views. Unparalleled Privacy. An Extraordinary Estate. Perched above the shimmering waters of Lake Hennessey, this extraordinary 100 acre estate offers a rare combination of breathtaking natural beauty, exceptional privacy, and refined Napa Valley living. Just minutes from the Silverado Trail in St. Helena, the property occupies a spectacular setting where panoramic lake views, rolling vineyards, and expansive open landscapes create an unparalleled sense of tranquility and seclusion. At the heart of the estate, an exquisitely remodeled 8,500 sq. ft. main residence embodies understated luxury and timeless sophistication. Thoughtfully designed for both intimate living and grand entertaining, the home features four bedrooms, four full and two half baths, two private offices, a light-filled solarium dining room, a chef's kitchen with an expansive pantry, and a wine cellar. Rich architectural details, including Venetian plaster walls, floor-to-ceiling Chinkapin oak pocket doors, custom ironwork, walnut hardwood, and French limestone flooring, reflect an exceptional level of craftsmanship throughout. Designed to embrace its remarkable surroundings, the estate offers a seamless connection between indoor and outdoor living. An infinity-edge pool appears to merge with the waters of Lake Hennessey, creating a breathtaking backdrop for relaxation and entertaining. Two beautifully appointed detached guest residences, approximately 1,000 and 1,200 sq. ft., provide luxurious accommodations for family and guests, complemented by a separate 60-foot lap pool. Beyond the residences, manicured gardens, elegant fountains, and thoughtfully designed outdoor gathering spaces create a private sanctuary. A full-size tennis court, bocce court, and approximately one acre of prized Pritchard Hill Cabernet Sauvignon vines further enrich the quintessential Napa Valley lifestyle. A world apart, yet moments from the heart of Napa Valley, this exceptional estate offers a level of privacy, scale, and natural beauty that is increasingly difficult to find. A rare opportunity to experience Wine Country living at its most extraordinary.
