Highlights
An Architectural Waterfront Estate on Shelter Island
A rare opportunity to own one of the East End’s most significant architectural homes—more than a house, it’s a lifestyle. Imagined by the Osofsky family and originally designed by Norman Jaffe in 1971, this waterfront estate was expanded by Jaffe himself in 1981—a rarity among his works. Recently renovated to preserve its architectural integrity while introducing modern comfort and luxury, the home offers a truly turn-key experience.
