List of tallest buildings and structures
The tallest artificial structure is Burj Khalifa, a skyscraper in Dubai that reached in height on January 17, 2009. By April 7, 2008 it had been built higher than the KVLY-TV mast in North Dakota, USA. That September it officially surpassed Poland's Warsaw radio mast, which stood from 1974 to 1991, to become the tallest structure ever built. Guyed lattice towers such as these masts had held the world height record since 1954.
Q1 (building)
When the Q1 was completed it overtook the 21st Century Tower in Dubai, United Arab Emirates to become the world's tallest residential tower. It is in the top 50 tallest buildings in the world when measured to its structural point, dwarfing the Gold Coast skyline with the closest buildings to Q1's height being the North Tower of Circle on Cavill and the Soul building.
