The estate unfolds across a beautifully wooded landscape, with walking trails connecting its residences, recreational amenities and extensive waterfront. A magnificent stone boathouse, substantial breakwater docking, expansive Ipe deck with integrated seating and McIntosh audio system, multiple sandy-bottom swimming areas and exceptional water access create a waterfront environment designed for generations of boating, swimming and gathering.
