A 1992-built waterfront estate located at 632 Halsey Neck Lane in Southampton hits the market for the first time, listed at $52 million. Previously owned by Atlantic Records co-founder Ahmet Ertegun and his wife Mica, the estate spans five and a half acres and includes an 11,000-square-foot main home designed in the style of a Russian dacha. The property features 10 bedrooms, 12 bathrooms, and two half-baths, with a private dock on a creek leading to Shinnecock Bay. The grounds boast a 75-foot-long outdoor pool and gardens with cherry and pear trees. Tim Davis of The Corcoran Group and Erica Grossman of Douglas Elliman share the listing.
