The original six-story structure, known as the Hearst Magazine Building or the International Magazine Building, was designed by architect Joseph Urban and architecture firm George B. Post & Sons, and completed in 1928 as the base of a future tower. The Hearst Magazine Building was designed in an early form of the Art Deco style. Henry Kreis designed six sculptural groups at the third story. The Hearst Magazine Building is the only survivor of an unbuilt entertainment complex that its developer, Hearst Communications founder William Randolph Hearst, had envisioned for Columbus Circle in the early 20th century. The tower, designed by Norman Foster, was completed in 2006, almost eight decades after the base was built. The Hearst Corporation and Tishman Speyer developed the tower, while WSP Global was the structural engineer and Turner Construction was the main contractor.
