The world's tallest twisted tower - Dubai
Another month, another new landmark for Dubai. Following on from the recent
opening of Dubai
Miracle Garden, billed as the world’s biggest natural flower garden, the
launch of Dubai
Design District and the release of plans to build
an underwater hotel in the area, the city has now inaugurated Cayan
Tower, the world’s tallest twisted tower.
Located by Dubai Marina, the 75-storey building rises to a height of 1,010ft
(307 metres) and houses 495 apartments. The swerve of the structure will
mean residents in the lower part of the tower will find their view oriented
towards the waterfront promenade of Dubai Marina; those on the upper floors
are rotated to face the Persian Gulf.
The unusual form of the building presented various challenges for its
designers – Skidmore Owings & Merrill LLP (SOM) – and developers. The
concrete structure rotates a hexagonal floor plate around a circular core
and the top of the tower is offset 90 degrees from the base. Corner and
interior columns of the tower twist as they ascend, but most of the
perimeter columns were shifted by a just a bit more than a single degree,
from floor to floor, resulting in a standardised construction method typical
to most large towers. As well as distinguishing the building, the twist also
greatly reduces wind force on the tower.
