Proposed as an idea in 2003 and owned by Emaar Properties , the Burj Khalifa takes the crown for the tallest building in the world . Construction began on the project a year later in 2004 and was originally named Burj Dubai . However , following financial difficulties , Sheik Khalifa , ruler of Abu Dhabi , provided extra funding to complete the building , and its name was later changed to the Burj Khalifa in his honour .
