The Willis Tower (formerly and informally: Sears Tower, its title until 2009) is a 110-story, 1,450-foot (442.1 m) skyscraper in Chicago. At completion in 1973, it surpassed the World Trade Center in New York City to become the tallest building in the world, a title that it held for nearly 25 years; it was also the tallest building in the Western Hemisphere for 41 years, before the new One World Trade Center surpassed it in 2013. While it held the title of'Tallest Office Building' before 2013, it dropped the title of'Tallest Man-Made Construction' after only 3 decades. The CN Tower in Toronto, which functions as a communications tower, took over the title in 1976.
The Willis Tower is considered a seminal accomplishment for engineer Fazlur Rahman Khan. It is currently the third-tallest construction in the USA and the Western hemisphere -- and the 23rd-tallest in the world.

The tower serves as a grade-A office construction. With sixty storeys, and 300 metres high (using a 45-metre spire), the building was the tallest tower in Kuwait until the construction of Al Hamra Tower in 2011. On January 19, 2010, The Council on Tall Buildings and Urban Habitat (CTBUH) announced that Arraya Tower was the 4th-tallest building completed in 2009. Curtis W. Fentress, FAIA, RIBA, of Fentress Architects, was the primary architect of the building, and Ahmadiah Construction was the primary contractor. The tower complements the Present 130-metre-high Arraya Tower housing offices and the Courtyard by Marriott hotel, as well as the upscale Arraya Shopping Mall and the Arraya Ballroom. Building on the tower began in February 2005, with occupation scheduled for February 2009. As of August 22, 2008, the tower was topped out and the superstructure was complete. Exterior cladding, consisting of white marble, green glass and steel rods, was largely complete. Interior works were well underway and wrapped up in early 2009 in time for the tower's opening.Source: WikipediaOcean Heights is a supertall residential skyscraper in Dubai Marina, Dubai, UAE.
