Although the building was originally planned to be entirely residential, Bloomberg L.P. negotiated a deal with Vornado Realty Trust to lease of office space at the base of the tower. STUDIOS Architecture did the design, which includes rows of uniform desks for approximately 4,000 employees and a large central atrium known as "the Link" that overlooks the courtyard. Paul Goldberger, in the August 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." By 2011, Bloomberg L.P. added another of office space at 731 Lexington Avenue and announced plans to expand to an additional in the former Philip Morris building at 120 Park Avenue. Bloomberg pays Alexander's, the owner of the building, $105 million in annual rent.
