The fifth tallest freestanding steel skyscraper in the World, its design used nine steel-unit square tubes in a 3 tube by 3 tube arrangement. Willis tower was the first building to use such a design.

Next, stands at 1,362 ft the Trump International Hotel and Tower with 91 floors. Alternatively known as Trump Tower, the building gets its name from the real estate developer Donald Trump.
Although set to become the world’s tallest structure, the plans got revised after 9/11. The Trump Tower Chicago also got featured in the series Build It Bigger and is always a place of interest for film and television fraternity.
