Capital Gate tower in Abu Dhabi, Dubai, designed by UK practice RMJM, has reached its final height of 525ft, by topping out its central core.
Dubbed Abu Dhabi's leaning tower, it leans at an angle of 18°, 14° more than the Leaning Tower of Pisa in Italy.
The tower will house the 189-rooms Hyatt hotel, office space, a cantilevered tea house on the 18 floor, an open sun terrace and a pool.
The tower is constructed on a 7ft concrete raft with a steel diagrid placed on 490 piles that have been drilled to 100ft underground.
Capital Gate tower, being developed by Abu Dhabi National Exhibitions Company, is part of the $2bn Capital City development project for business and residential complexes.
