The building, which is under construction in Abu Dhabi, leans eastward at four times that of the Leaning Tower of Pisa - at 18 degrees compared to the latter's four degrees.
Because of its posture, the tower is being constructed on top of a dense mesh of reinforced steel. The dense mesh sits above an intensive distribution of 490 piles which have been drilled 30 m underground to accommodate the gravitational, wind and seismic pressures caused by the lean of the building.
ADNEC Group chief executive Simon Horgan said: "Capital Gate will be a building that the world will talk about, not because it has surpassed another building as the world's tallest, but because of its aesthetic splendour and technical achievement." "
Capital Gate will be 'one of a kind' added David Pringle, chief executive, RMJM Asia and the Middle East, who are project architects.
He said: "Its graceful, asymmetric diagonal structure, known as a ‘diagrid', supports the tilting external load of the building and we believe that this is the first building in the world to use a pre-cambered core."
Capital Gate will accommodate the 5-star ‘Hyatt at Capital Centre' hotel and will provide the most exclusive office space in Abu Dhabi. The tower forms a major part of the Capital Centre development, an AED8 billion (£1.3 billion) business and residential micro city being constructed around the Abu Dhabi National Exhibition Centre.
