At 828 metres in height, the Burj Khalifa has been officially recognized as the world’s tallest building.

In an unsurprising announcement, the Council on Tall Buildings and Urban Habitat (CTBUH) bestowed the ‘tallest’ title after checking detailed documents provided by the building’s developer Emaar.

The Burj Khalifa surpassed the previous tallest building, Taipei 101, by 320m, an unprecedented increase of 61%.

According to information from CTBUH, the Burj Khalifa has become the 16th building to hold the title of the ‘World’s Tallest’ and stands an additional 773m higher, than the world’s first tall building, the Home Insurance Building completed in Chicago in 1885.
