Which New York City skyscraper became the world's tallest residential building when completed in 2021?

Central Park Tower became the world's tallest residential building when it was completed in New York City in 2021.

The skyscraper stands at 472.4 meters (1,550 feet) and contains luxury condominiums, making it one of the most prominent projects in Manhattan's Billionaires' Row district. Its height exceeds that of other nearby residential towers, including 432 Park Avenue and 111 West 57th Street.

The building was developed by Extell Development Company and designed by Adrian Smith + Gordon Gill Architecture. Construction began in 2014, and the tower's residential status distinguishes it from mixed-use or primarily commercial skyscrapers.

Central Park Tower is sometimes confused with One World Trade Center, which is taller overall but is primarily an office building. The tower's name refers to its location beside Central Park, while its former development name was Nordstrom Tower, after the department store occupying its lower levels.
