The Mile-High Illinois, Illinois Sky City, or simply The Illinois is a concept proposal for a skyscraper that was to be over 1 mile (1,600 m) high and was conceived and described by American architect Frank Lloyd Wright in his 1957 book, A Testament.[1] The design, intended to be built in Chicago, included 528 stories, with a gross area of 18,460,000 square feet (1,715,000 m2). Wright stated that there would be parking for 15,000 cars and 100 helicopters.
If built, it would top the list of the tallest buildings in the world by far, being more than four times the height of the Empire State Building, almost twice as tall as the world's current tallest building, the Burj Khalifa; and about 2,400 feet (730 m) taller than the planned Jeddah Tower – the latter two both designed by Adrian Smith, whose designs for both buildings are said to have been inspired by that of The Illinois.[2][3]
