Spiralling skyscrapers are more popular than ever according to a new industry study charting twisted buildings around the world.
The latest report from the Council on Tall Buildings and Urban Habitat (CTBUH) has revealed that there are now 28 skyscrapers with twisted structures either built or under construction.

The tallest of these is Gensler's 632-metre-high Shanghai Tower ? currently the second tallest building in the world.
The list includes several recent projects, including the 306-metre-high Cayan Tower in Dubai by SOM, MAD's curvaceous Absolute World Towers in Canada ? dubbed the Marilyn Monroe towers ? and BIG's new residential project Miami. The list also includes the elaborately twisted Diamond Tower, which currently under construction in Saudi Arabia. Photograph by thebig5hub.com
It also features several structures under construction, from the elaborately twisted Diamond Tower in Saudi Arabia to the plant-covered tower shaped like a DNA strand in Taiwan.
CTBUH defines a twisting building as one that progressively rotates its floor plates or its facade as it gains height.
