yes it is Burj Khalifa like the other person said.
Explanation:
The organization currently ranks Burj Khalifa in Dubai as the tallest at 828 m (2,717 ft). The CTBUH only recognizes buildings that are complete however, and some buildings included within the lists in this article are not considered finished by the CTBUH.
The world's tallest structure tower is the 829.8-metre-tall (or approximately 2,722 feet) located in Burj Khalifa, Dubai. The building was awarded "Tallest Building in the World" in January, 2010.
