Q1 (an abbreviation of Queensland Number One) is a supertall skyscraper in Surfers Paradise, on the Gold Coast, Queensland. It lost its title as the world's tallest residential building to the 337-metre The Marina Torch in Dubai on 29 April 2011. It is now the sixth tallest residential tower in the world and is the tallest building in Australia and the Southern Hemisphere and the second-tallest free-standing structure in the Southern Hemisphere, behind the Sky Tower in Auckland, New Zealand. The Q1 officially opened in November 2005.
The landmark building was recognised as one of Queensland's icons during the state's 150th birthday celebrations.
At 322.5 m (1,058 ft) and with a roof height of 245 m (804 ft), Q1 qualifies as the world's seventh tallest all-residential building when measured to the top of its structural point (spire), but is ranked lower behind buildings including The Marina Torch at 337 metres in Dubai and Melbourne's Eureka Tower (roof height of 297.28 metres (975.3 ft)) when measured to its roof height and highest inhabitable floor. However, according to the ranking system developed by the US-based Council on Tall Buildings and Urban Habitat, the main criterion by which buildings are ranked is the height of the top of the spire, qualifying Q1 as the taller.
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 as of December 2011[update] 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 220 m (720 ft) North Tower of Circle on Cavill and the 243 m (797 ft) Soul building.
