A Hamptons property at 43 East Dune Lane in East Hampton is set to list for $162 million, a significant increase from its $72 million purchase price just five months ago. The current owner acquired the estate in March and has since commissioned plans for a new, expansive residence and guest cottage, designed by a team including the late architect Robert A.M. Stern and master custom builder Ed Bulgin.
The planned construction will replace the existing home with a 17,500-square-foot main house and a 3,500-square-foot guest house, situated on 3.6 acres with 225 feet of ocean frontage. The property is designed to offer 270-degree ocean views, a rare basement for coastal Hamptons properties, and proximity to the ocean and Hook Pond.
Plans for the new residence include nine bedrooms and 11 full and two half bathrooms spread across three levels. Amenities will feature an elevator, dual staircases, a primary suite with a private porch and office nook, and an additional second-floor wing. The lower level is designated for recreation and wellness, with a golf simulator, gym, cold plunge, sauna, playroom, and snack bar. Outdoor features include a sunken tennis court, a garden, a terrace, and a 20 by 80-foot rimless pool.
The property's listing places it in competition with other high-value Hamptons properties. Calvin Klein's former compound on East Dune Lane was listed in June for $165 million, and the Sagaponack estate of hedge fund manager Zach Schreiber was listed the same month for $152.5 million. The current record for the most expensive residential property in the area stands at $147 million, set in 2014.
The history of the East Dune Lane property includes its former ownership by Lee Radziwill, sister of Jacqueline Kennedy Onassis. She purchased the estate in the late 1980s for over $6 million and resided there with her then-husband, Herbert Ross. In the late 1990s, a sale to comedian Jerry Seinfeld for $19 million was reportedly called off after a dispute between Radziwill and Ross.
The anonymous buyer of the property in March utilized a shell company, with records indicating ties to a Manhattan co-op. The development team also includes landscape architect Ed Hollander. Building permits for the new construction are expected to be filed within the next two weeks.
