One Beacon Court (also called the Bloomberg Tower), is a skyscraper on the East Side of Midtown Manhattan, New York City. It houses the headquarters of Bloomberg L.P. in the lower floors and luxury condominiums in the higher floors. It is located at 731 Lexington Avenue between East 58th and 59th streets. It was built on the site of the flagship Alexander's Department Store, which was torn down in 2000. The mid-block public space at the base of the building is called Beacon Court. The building stands at 54 stories tall, reaching 806 feet (246 meters). It is currently the 15th tallest building in New York and the 46th tallest in the United States. The building's zip code is 10022. Several buildings were demolished to make way for the Bloomberg Tower (the tallest being the Barclay-Garrett Building).
Paul Goldberger in the Aug. 6, 2007, issue of the New Yorker magazine lauded the Bloomberg offices as: "a newsroom truly designed for the electronic age ... a dazzling work environment tucked inside a refined but conventional skyscraper."
