Infinity Tower by SOM (Dubai)
Cayan Tower, known as Infinity Tower prior to its inauguration, is a 306 metres (1,004 ft), 80 story skyscraper in Dubai, United Arab Emirates by Cayan Real Estate Investment and Development. The tower is designed by Skidmore, Owings and Merrill SOM architectural group, the same group who built the Burj Khalifa also in Dubai and Trump Tower in Chicago. Upon its opening on 10 June 2013, the tower has become world's tallest high rise building with a twist of 90 degrees.Construction of the 306 m (1,004 ft) building began in February 2006 and topped out in 2012. It has 76 stories and became the world's tallest high rise building with a twist of 90 degrees. The tower twists in a similar way to that of theTurning Torso in Malmö, Sweden, and other recent projects in Doha and elsewhere, and became the tallest in the world to do so. However, unlike the Turning Torso, which is a series of cantilevered plates rotated about a straight structure, Cayan Tower's much larger floor plates actually require the structure to be twisted as it raised from level to level. Each floor is rotated by 1.2˚ to achieve the full 90˚ spiral, creating the shape of a helix. The tower also has residential apartments, conference rooms, tennis courts, pools, a state of the art gymnasium, a nursery and a spa. An earlier design was for a taller, darker tower 372 m (1,220 ft) tall with 93 floors.
