18-Unit UES Building To Become Single-Family Mansion, Records Show

UPPER EAST SIDE, NY — A landmarked building on the Upper East Side is being transformed from 13 apartments and five offices into one five-floor mansion, according to recent filings with the city.

The five-story apartment building at 51-53 East 73rd Street, located between Park and Madison Avenues, will be transformed into a single-family mansion, according to plans filed with the New York City Department of Buildings this week.

The filings, first reported by Crain's New York Business, showed that Eric Goodman, managing partner at Long Island-based private equity firm Goodman Capital, submitted the plans. Goodman filed the permits under the LLC, Chai 73, Crain's reported.

The building, which is part of the Upper East Side Historic District, was built in 1885-86 as a pair of Queen Anne-style rowhouses designed by John G. Prague. In the 1940s, the buildings were combined and a single entrance was created, and in 1982, the building was landmarked.

It was auctioned off for $25 million at a bankruptcy sale three years ago to Chai 73, records show.
