The Council on Tall Buildings and Urban Habitatrecently published The Tallest 20 in 2020: Entering the Era of the Megatall. Within this decade, the World’s first kilometer-tall building will be constructed, along with many other buildings over 600-meters tall. “The term “supertall” (which refers to a building over 300 meters) is thus no longer adequate to describe these buildings: we are entering the era of the “megatall (over 600 meters).
The list does not include the Broad Group Sky City or any other potential Broad Group skyscrapers.
Broad Group already has the architectural designs for a 636 story super Sky City that would be 2000 meters tall.
This would be beyond the megatall category and would be supermega building over 1200 meters tall. It would be approaching the next category that is two categories beyond megatall which would be buildings over 2400 meters tall.
Dubai’s two tallest buildings both offer interesting statistics. The Burj Khalifa’s total vanity height is 244m which, on its own, would stand as Europe’s 11th tallest skyscraper. The Burj Al-Arab, on the other hand, has “the greatest vanity ratio of any supertall building” with 124m (39%) of its total 321m height “devoted to non-occupiable space above the highest occupiable floor”. The average vanity height in the UAE is 19%, making it the nation with “vainest” supertall buildings. China's skyscrapers average 14% vanity height. US skyscrapers have averaged 13% vanity height.
The highest occupied floor of the Burj Khalifa is at 580 meters and the public observatory is at 450 meters.
The Broad Group Sky City should have a 727 meter occupied floor and public observatory on its roof.
In the USA, the Bank of America tower in New York has an occupied floor height of 235m, leaving 131m (or 36%) non-occupiable. The CTBUH predict that once One World Trade Centre is complete in 2014, New York City will be home to three of the world’s top ten vanity heights.
