The Rookery Building is a historic office building located in Chicago, Illinois. Completed by architects Daniel Burnham and John Wellborn Root of Burnham and Root in 1888, it is considered one of their masterpiece buildings, and was once the location of their offices. The building is 181 feet (55 m) in height, twelve stories tall, and is considered the oldest standing high-rise in Chicago.
It has a unique construction style featuring exterior load-bearing walls and an interior steel frame, providing a transition between accepted and new building techniques. The lobby was remodeled in 1905 by Frank Lloyd Wright. The second renovation, completed August 24, 1931, by former Wright assistant William Drummond, modernized many of the interior elements, including new elevators, and brought period touches to the building, such as Art Deco detailing.
