Cayan Tower: the world’s first skyscraper built without pillars

UAE - January 2, 2017
Cayan Tower

Cayan Tower has been named the world’s tallest spiraling skyscraper, at an altitude of 307 meters, to be built without pillars.

The tower is designed a 90-degree curve, giving each apartment a different view of Dubai Marina and the Arabian Gulf.

Cayan Tower is not limited to its altitude and unique curvature, as it also features a bizarre engineering design.

It was built with the application of unique architectural concepts based on open space technology, so as to ensure there are no pillars anywhere in the building.

The 73 floor Cayan Tower was designed by “Skidmore, Owings, and Merrill” and cost nearly one billion dirhams.

Arabtec began construction of the tower in 2006, and by 2012 had reached the intended height.

The building’s exterior is made up of bending floor boards and each floor turns by 1.2 degrees in order to reach 90 degrees on the last floor, giving it the spiraling shape.

The exoskeleton is plated with a layer of titanium which contributed greatly to reduced sunlight.

Cayan Tower features external panels that open and close automatically depending on the weather.

It has 7 elevators and a 5-story basement garage.
