When Donald Trump bought the Old Headquarters for Gulf and Western, he wanted to transform the original 45 story office building into a hotel and apartment building. This required his architects, Philip Johnson and Costysis Kandilis to add an additional 7 floors (for a total of 52) and reclad the original beige stone and glass building with black glass. At the base Trump placed a stainless steel globe which was purported to be inspired by the Unisphere at the former world's fair in Queens.
