The two buyers wanted to be in the same building and “saw this as an opportunity to create unique spaces together,” said Ramin Kamfar,CEO of Bluerock Real Estate, which is developing the project with Victor Group. Mr. Kamfar declined to identify the buyers but said they are American. Both sales closed last week.

One of the apartments—a combination of three units spanning the top four floors—sold to one buyer for $37.94 million. The price is the highest ever paid for a home on the Upper East Side east of Third Avenue, according to real-estate appraiser Jonathan Miller.
