A beautiful view of Burj Khalifa from the base of the magnificent building. The tallest man made structure in the world at a total height of 829.8 m (2,722 ft) will soon be over-shadowed by the Creek Tower that is under construction (estimated height of at least 1,000 m or 3,300 ft). Burj Khalifa was designed by Adrian Smith, of Skidmore, Owings & Merrill, whose firm designed the Willis Tower and One World Trade Center.
