Dubai no longer owns the top floor of their tallest building

Due to the new vertical regulations passed last week, it has been determined that Dubai’s Burj Khalifa, the tallest building in the world, has at least one floor higher than the country’s vertical boundaries.

The building stands at approximately 2,625 feet. Last week’s international conference determined that vertical boundaries for any given nation should end at 790 meters, or about 2,592 feet. The new regulation was intended to allow duty free shopping on all flights — including smaller, private planes — but it looks as though the Burj Khalifa may have been an oversight.

Representatives from Dubai have yet to make an official comment or to disclose whether this regulation will affect just one or two levels of the Burj Khalifa. There is a rumor that they have begun talks to open a duty free shop right in their top-floor observation deck.
