Q1

Q1 Tower (an abbreviation of Queensland Number One) is a skyscraper from Skyscrapers:Battle Mode. aA322.5-metre (1,058 ft) skyscraper in Surfers Paradise, Queensland, Australia. The residential tower on the Gold Coast was the world's tallest residential building from 2005 to 2011. As of 2020 it is the ninth-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.

At 322.5 metres (1,058 feet) 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 Melbourne's Australia 108 (roof height of 316.7 m (1,039 ft)) and the Eureka Tower (roof height of 297.3 m (975 ft)) when measured to its roof height and highest inhabitable floor. However, according to the ranking system developed by the U.S.-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 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-metre (720 ft) North Tower of Circle on Cavill and the 243-metre (797 ft) Soul building.

Q1 Tower was designed by SDG & The Buchan Group, and its form was inspired by the Sydney 2000Olympic torch and the Sydney Opera House. The name was given in honour of members of Australia’s Olympic sculling team of the 1920s – Q1.

The concept was based on studies of wind, movement and tension in which a series of ribbons wrap concentrically around the tower form and hover above the entry plaza area providing cover and shading. The tension in the movement and free form are expressed by the gradual twisting of the aluminium-clad ribbons as they move around the building. The result is an open-air galleria-like shopping precinct under the glazed ribbon structure and a curved retail façade to the street edges.

The project was developed by The Sunland Group and built by Sunland Constructions. The building was the Silver Award winner of the 2005 Emporis Skyscraper Award, coming in second to Turning Torso in Sweden.

Q1 was completed towards the end of 2005. Its main point of difference to other high-rise in Surfers Paradise is its glass-enclosed sleek look. Q1's lift lobby is separated into two high-speed lift groups. Four high speed lifts service levels B2 to level 42. Three separate high-speed lifts service levels 43 to the penthouse on level 74.

The building is supported by 26 piles, each two metres (six point six feet) in diameter, that extend 40 metres (130 ft) into the ground passing through up to four metres (thirteen feet) of solid rock. Q1 contains one-, two- and three-bedroom units. Building facilities include two lagoon swimming pools, a lap pool, gymnasium, small theatre, a ballroom and a spa centre.

An application to construct a walkway around the outside of level 78 was lodged with the Gold Coast City Council in mid-2010.
