An oceanfront estate at 43 East Dune Lane in East Hampton Village has traded hands for $72 million, the largest known East End sale so far in 2026. The 3.6-acre compound, long known as Dune Cottage, packs in an 11,000-square-foot main house, a 1,500-square-foot guest studio, a Har-Tru tennis court and a heated oceanside pool tucked into the dune. The buyer’s identity has not been made public.
Sale details
The $72 million sale price was reported by The Real Deal, while recently sold records from Compass show the closing was recorded on March 6, 2026. The seller was Ann Tenenbaum, widow of private-equity pioneer Thomas H. Lee. The property first hit the market in June 2024 with an eye-popping $120 million asking price before being reduced to $84.9 million.
What’s on the grounds
Local listing materials describe a main residence of roughly 11,000 square feet with 10 bedrooms and 12 full baths, along with about 225 feet of private white-sand ocean frontage. The estate’s amenities include a 24-by-58-foot heated pool, a 1,500-square-foot recreation pavilion and a Har-Tru tennis court, according to coverage in Behind The Hedges and related listing descriptions.
Legacy and past owners
Built in 1910, the house was originally part of an 80-acre Wiborg estate. Lee and Tenenbaum paid about $16.2 million for the property in 2001 and rebuilt the home twice, including after a 2013 fire, The Real Deal reports. Earlier owners included Lee Radziwill and her then-husband, director Herbert Ross, a social pedigree that has long added to the property’s Hamptons cachet. Lee’s death in February 2023 preceded the decision to put the estate on the market.
Where this sale fits
Industry data show that the Hamptons luxury market was unusually active in late 2025. A fourth-quarter report from Douglas Elliman, prepared by Miller Samuel, pegged the median sale price around $2.3 million and highlighted a record number of transactions at $5 million and above. That hot streak set the stage for headline-grabbing deals, including the single-parcel, off-market sale of 408 Further Lane for roughly $115 million, according to regional coverage cited by Newsday. Scarcity of prime oceanfront lots continues to push top-tier prices higher, a trend tracked in reports from Douglas Elliman and Miller Samuel.
Who marketed the home
The listing was handled by Compass broker Terry Cohen and the Modlin Group, who oversaw marketing while the property was on the market, according to the Compass listing. The deal closed quietly, with the buyer remaining undisclosed, which tracks with the ultra-luxury Hamptons playbook where discretion is often built into the deal. Local brokers note that the combination of privacy and limited inventory is a big reason these trophy properties continue to fetch such lofty numbers.
