Facts

  • The official height was increased to from 886 feet to 1,007 feet when the CTBUH began to include ornamental spires during the Sears-Petronas height controversy.
  • The lobby extends all the way through the block, connecting AT&T to the USG Building with a full-height atrium in the link between them.
  • The elevator banks in the lobby are lit by flamboyant bands of neo-deco lighting extending from one wall to the other.
  • At night the setbacks, finials, and spires are accented by softly colored lights.
  • This is the tallest building constructed in Chicago during the last quarter of the 20th century.
  • The building's mass narrows gradually with small setbacks at the 15th, 30th and 45th floors. This form of telescoping evolved into the pagoda-like form of the same architect's Jin Mao Tower in Shanghai.
  • Designed by Adrian D. Smith, FAIA, RIBA Design Partner at Skidmore Owings & Merrill LLP.
  • The lobby is one of the most lavish and sumptuous in Chicago, with stylized lighting fixtures and marble walls and floors in bold, brightly colored patterns.
  • Tishman Speyer acquired this property in an announcement made on December 5, 2004 along with 11 other buildings including the USG Building.
