 The newly reconstituted Tishman Speyer Properties bought the building for $518 million in 2000 (about $ million in ), and about the same time Tishman also bought Rockefeller Center.Shortly after the purchase, Tishman enclosed the atrium walk-through and added a third retail tenant, Hickey Freeman with a new store designed by Robert A. M. Stern.The enclosure cut off the Fifth Avenue entrance, and access now has to be via 52nd or 53rd Street.
