Emaar Properties officially opened the 828-meter Burj Khalifa in Dubai, timed to the fifth anniversary of Sheikh Mohammed bin Rashid Al Maktoum's accession to power. The tower took the world's-tallest-building title from Taipei 101 by a record margin.

Dubai's One Za'abeel opened to the public, its twin towers joined by The Link, a 230-metre skybridge that went on to set the Guinness World Record for longest cantilevered building.
