Along with being the tallest building in the world, the Burj Khalifa in Dubai is now the world's 'vainest', according to new research.
The Burj Khalifa tower is a total of 828 metres tall but at least 244 metres (29 per cent) cannot be inhabited and is simply 'vanity height'. Without the 'vanity height' the building would be an impressive skyscraper and if the Burj Khalifa was in Europe it would be one of the tallest buildings on the continent.
The findings come from the Council on Tall Buildings and Urban Habitat, who analysed the tops of the tallest buildings in the world to discover how much of it was unoocupiable space.
It's just part of a growing trend of adding 'vanity' height to a structure to make it taller without serving a practical purpose.
The Zifeng Tower in Nanjing, China came in second with 133 metres of 'vanity height' and the Bank of America Tower in New York came in third place with 131 metres of uninhabitable height.
Other buildings in the top 10 included the New York Times Tower and Minsheng Bank Building in Wuhan, five of the structures in the list are in Dubai.
Without 'vanity height' 44 of the world's 72 tallest buildings would be less than 300 metres.
