This duplex at 860 United Nations Plaza was once the home to the world-famous ballet dancer Sono Osato, who passed away in 2018 at age 99, and her husband, developer Victor Elmaleh, who predeceased her in 2014 at age 95.

It’s now on the market for $3.49 million.

The three-bedroom home opens to a large entry foyer that leads to a 30-foot corner living room with a woodburning fireplace, large windows and views of the East River.

The home has an internal elevator as well as a “modernist” staircase, a formal dining room with river views and an eat-in kitchen.

Building amenities include a gym, multiple roof decks, a library, a garage, a private driveway and a game room.

Osato, who was the first American dancer to join the Ballet Russes de Monte Carlo, danced with the American Ballet Theatre.

Her husband, who developed $7 billion worth of real estate, was chairman of World Wide Group and imported some of the first Volkswagens to the United States.

The listing broker is Stribling’s Pamela D’Arc.

The Osato/Elmelah estate is also selling the couple’s Bridgehampton home at 236 Quimby Lane for $34 million — a listing that’s now in contract. The listing broker is Sotheby’s Deborah Srb.
