Take A Peek Inside 432 Park Avenue, the Tallest Residential Building in the Western Hemisphere...While the towering buildings of the New York City skyline are constantly changing, shifting, and growing, it is rare to have any construction project overtake the most famous skyscrapers in the city. This is particularly true of apartment buildings. However, as of October 2014, when the last bit of concrete was poured, the new building at 432 Park Avenue is the tallest residential building not only in Manhattan, but in the entire western hemisphere. The building sits between 56th and 57th streets, overlooking Central Park and huge swaths of the city. In fact, some condos even have views all the way out to the Atlantic.
