Capital Gate, the most leaning building in the world. Capital Gate will house Abu Dhabi’s first Hyatt hotel, a presidential-style luxury, 5-star hotel and will provide 200 hotel rooms.
The central core of the building slants in the opposite direction to the lean of the structure, and it straightening as it grows. It sits on top of a 7-foot-deep concrete base with a dense mesh of reinforced steel. The steel exoskeleton known as the diagrid sits above an extensive distribution of 490 piles that have been drilled 100 feet underground to accommodate the gravitational, wind and seismic pressures caused by the lean of the building.
