It was only a matter of time until the $100 million NYC apartment sale barrier was broken. As expected by New Construction Manhattan, the most expensive sale of a New York City residential unit in history has transpired at the yet-to-be finished One57, a new Manhattan condominium that has already accumulated hundreds of millions of dollars in apartment sales. Expected to shell out $250 million in total, Qatar’s powerful prime minister, Sheik Hamad bin Jassim bin Jaber al-Thani, is purchasing the city’s most expensive penthouse, along with four separate full-floor condos in the 90-story building.
