List of tallest buildings in Chicago

Skyline of Chicago from northeast

This list of tallest buildings in Chicago ranks skyscrapers by height in the U.S. city of Chicago, Illinois, which is considered to be the birthplace of the skyscraper.[1][2] The tallest building in Chicago is the 108-story Willis Tower (formerly Sears Tower), which rises 1,451 feet (442 m) in the Chicago Loop and was completed in 1974.[3] It also stands as the tallest building in the United States, and the fifth-tallest building in the world. In addition, the Willis Tower has the second most floors of any completed building in the world, and stands as the world's second tallest completed skyscraper when measuring to pinnacle height,[3] rising 1,730 feet (527 m) with the addition of its western antenna.[4] The second-, third- and fourth-tallest buildings in Chicago are the Trump International Hotel & Tower, the Aon Center and the John Hancock Center, respectively. As of June 2008, the John Hancock Center, with 49 floors of condominiums,[5] holds the world record for the highest residence.[6] In addition, Chicago has the distinction of being the only city in the world with more than one completed building containing at least 100 floors.[A]

The history of skyscrapers in Chicago began with the 1885 completion of the Home Insurance Building, which is often regarded as the first steel-framed skyscraper in the world. The building was originally constructed with a height of 138 feet (42 m) and 10 stories, and was later expanded to a height of 180 feet (55 m) and 12 stories before being demolished in 1931.[7][8] Historically, Chicago has played a prominent role in the development of the skyscraper. The Masonic Temple Building was the tallest building in the world using the unconventional definition that excludes the New York World Building's ornamental lantern.[9] Three past buildings have been considered the tallest building in the United States, including the Chicago Board of Trade Building, which in both of its incarnations held the title of Chicago's tallest building.[10] Chicago went through a very early high-rise construction boom that lasted from the early 1920s to the mid-1930s, during which time 11 of the city's 91 tallest buildings were constructed. The city then went through an even larger building boom that has lasted from the early 1960s until the present. During this time, the city has seen the completion of 79 buildings rising at least 500 feet (152 m) in height, including the Sears Tower, the Aon Center and the John Hancock Tower. The high-rises that have been constructed are mostly concentrated in the Loop and along the Magnificent Mile in Chicago's Near North Side community area. Chicago is the site of 91 completed buildings that stand at least 500 feet (152 m) in height, with 16 more under construction. Overall, the skyline of Chicago is ranked (based on existing and under-construction buildings over 500 feet (152 m) tall) first in the Midwestern United States and second in the United States, after New York City.[B] As of October 2009, there are 1,105 completed high-rises in the city, second in the country behind New York.[11] Based on the average height of the ten tallest completed buildings, Chicago has the tallest skyline in the world.[12]

Chicago has two buildings under construction that are planned to exceed 1,000 feet (304.8 m) in height: the 2,000-foot (610 m) Chicago Spire,[13] and the 1,362-foot (415 m) Waterview Tower.[14] The 150-story Chicago Spire, upon its completion in 2012, would become the tallest building in the United States and the second tallest building in the world.[13] The tower would also stand as the tallest all-residential building in the world,surpassing Q1 in Gold Coast, Queensland, Australia.[15] There are also several buildings proposed for construction in the city, the largest being the Waldorf-Astoria Hotel and Residence Tower, which would rise 1,265 feet (386 m) and 107 floors upon its completion in 2012.[16] As of June 2008, there are 160 high-rise buildings under construction, approved for construction, and proposed for construction in Chicago.[11]

Tallest buildings by pinnacle height

One Prudential Plaza is the eighth-tallest building in Chicago when measuring by pinnacle height.

This list ranks Chicago skyscrapers based on their pinnacle height, which includes radio masts and antennas. As architectural features and spires can be regarded as subjective, some skyscraper enthusiasts prefer this method of measurement. Standard architectural height measurement, which excludes antennas in building height, is included for comparative purposes.
