Set along the pristine south shore of Green River Reservoir, Ondine is an extraordinarily rare lakefront estate-one of only four private residences on a 5,500-acre protected expanse within Green River Reservoir State Park. Encompassing 15.9± acres with an exceptional 1,000 feet of shoreline, this secluded retreat offers unmatched tranquility on Vermont's largest non-motorized lake, where quiet waters invite kayaking, sailing, and reflection. Thoughtfully designed as a multi-residence compound, the estate includes four furnished and fully independent living quarters: a distinctive octagonal main house with three bedrooms, a guest house with lofted accommodations, a guest apartment, and a studio-each with private systems, kitchens, and climate control. Two heated two-car garages, twin barns with extensive equipment, and a well-appointed boathouse complete the offering, while a private beach and boat launch frame the shoreline. Despite its peaceful isolation, everyday conveniences in Morrisville are just 10 minutes away, with the renowned dining and boutiques of Stowe a short drive beyond, and Burlington International Airport within easy reach. Currently operated as a successful luxury rental, Ondine presents a singular opportunity to own a legacy waterfront estate.
