Dubai, United Arab Emirates — The world’s tallest building has been officially unveiled on Wednesday, a few weeks after the first tower was officially unveiled in the U.S. and two weeks after a similar tower in Hong Kong.
Dubai’s new 7.7 million-square-foot Burj Khalifa is a 7,800-foot-tall skyscraper that will feature a glass floor and a glass roof, and will feature two floors of glass.
The building will also feature a “shelter” of steel and glass that will support the weight of the building.
Dubai is planning to build a 7.6 million-foot building on the site of the old World Trade Center site, which is now being used as a residential neighborhood.
It is being designed by architects Arup and is expected to cost $5 billion.
