Envisioned by architect Welton Becket, Century City broke ground in 1961 on the old 20th Century Fox back lot studios and was built on the premise of creating a multimillion dollar mixed use residential, hotel and commercial area. Century City was labeled a "City within a City" and its first buildings were The Broadway department store and Gateway West, the first office building in the new city. The Towers were designed by I.M. Pei in 1964, and were originally built as luxury rental apartments. The project was later converted to condominiums in 1973 by S. Jon Kreedman & Company.
