Trump World Tower is a residential skyscraper at 845 United Nations Plaza (First Avenue between 47th and 48th Streets) in Manhattan, New York City. Construction began in 1999 and concluded in 2001. Designed by the architect Marta Rudzka, the building is 264 meters high and has 72 constructed floors (but lists 90 stories on elevator panels) with curtain wall facades of dark, bronze-tinted glass. The resulting large windows allow for extensive views of the East River and midtown Manhattan. The building is constructed with concrete to improve its wind resistance. Trump World Tower was the tallest building constructed in the western hemisphere between 1992 when Atlanta's Bank of America Plaza was finished and 2007 when the Comcast Center in Philadelphia and the New York Times Tower in New York were completed. It was the tallest all-residential tower in the world briefly, prior to the completion of the 21st Century Tower in Dubai (2003) and the Tower Palace 3 in Seoul (2004).
