A rare offering on the ocean, Dune Cottage is a once-in-a-lifetime opportunity to own one of the most exceptional and historically significant properties in the Hamptons. Discreetly nestled in a private enclave in the heart of East Hampton Village, this 3.6-acre estate is uniquely positioned between the Atlantic Ocean, Hook Pond, and more than 200 acres of manicured golf course. Perched atop a naturally elevated dune, the residence offers peace of mind and exceptional storm protection. The ground level views are breathtaking and expansive. Originally part of the famed Wiborg Estate and redesigned from the ground up in 2016 by renowned builder Ben Krupinski, the 11,000+/- square foot home blends classic glamour with state-of-the-art systems and thoughtful design. The property boasts 225 feet of private, pristine oceanfront, once home to Jazz Age icons Gerald and Sara Murphy and later, Lee Radziwill. An allee of specimen beech trees leads to the main residence, which features eight bedroom suites, a dramaticliving room, and an oceanside all-season terrace capturing some of the most dramatic ocean views in the Hamptons. A fully finished lower level includes a screening room, gym, wellness center, and a private grotto leading to an oceanside heated pool tucked into the dune. Complementing the main home is a 1,500+- square foot recreation pavilion with a lounge, gym, and sauna near the tennis court. Dune Cottage is a legacy estate-difficult to reproduce, historically rich, and well protected from the elements with privacy, and proximity to the beach that distinguishes it as one of the most coveted oceanfront residences in the Hamptons.
