Q1 (meaning Queensland Number One) is a skyscraper in Surfers Paradise, on the Gold Coast, Queensland. It lost its title as the world's tallest residential tower to the 348 metre building The Marina Torch in Dubai on 29 April 2011. As of May 2012[update], it is the fifth tallest such building. Q1 is the tallest building in Australia and the Southern Hemisphere when measured to the top of its spire (third tallest building behind Eureka Tower and Rialto Towers, both in Melbourne, Victoria, when measured to roof and highest habitable floor) and the second-tallest free-standing structure in the Southern Hemisphere, behind the Sky Tower in Auckland, New Zealand. It opened in November 2005.
The landmark building was recognised as one of Queensland's icons during the state's 150th birthday celebrations. Q1 has been identified as a potential terrorism target for the region. For a short time, an apartment in the building, which was bought for A$9 million by a Japanese restaurateur, was the most expensive ever paid for in Queensland.
At 322.5 m (1,058 ft) and with a roof height of 245 m (804 ft), Q1 qualifies as the world's third[dated info] 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 348 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 completed, Q1 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 under-construction 250 m (820 ft) Soul building.
Design and construction 
Q1 Tower was designed by Atelier SDG, and its form was inspired by the Sydney 2000 Olympic 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 design of the podium, retail ground plane, entry foyer and canopy was by Innovarchi (directors Ken McBryde and Stephanie Smith). 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 facade 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.
The building is supported by 26 piles, each two metres in diameter, that extend 40 metres into the ground passing through up to four metres (13 ft) of solid rock. Q1 contains one, two and three bedroom apartments. Building facilities include two lagoon swimming pools, a lap pool, gymnasium, small theatre, a ballroom and a spa centre.
Observation deck 
SkyPoint, formerly known as QDeck, is an observation deck at levels 77 and 78. It is Australia's only beachside observation deck and has room enough for 400 people. It towers 230 metres above the Surfers Paradise beach, giving viewers a 360 degree view of Brisbane to the north, the Gold Coast Hinterland to the west, Byron Bay, New South Wales to the south and the Pacific Ocean to the east. The express elevator to the observation deck travels the 77 floors in 43 seconds.
Building condition 
In 2009, reports of disrepair and poor building conditions emerged. Peeling paint which has revealed rusty steel inside and outside, as well as shattered glass panels are amongst the visible concerns. The Building Services Authority has confirmed it has received complaints in relation to the building. The north stairwell was assessed as defective due to the stairwell pressurisation system not meeting the minimum air flow requirements during a fire emergency. The Building Services Authority asked Q1's builders to rectify the problem in July 2010.
Q1 has been used as a fireworks launch site during New Year's Eve celebrations. The building is one of the most popular destinations for students celebrating Schoolies Week, despite the body corporate committee treasurer's claims that most of the building's unit owners were opposed to their stay.
On 28 March 2007, two base jumpers made an early morning jump from a northern side apartment. Base-jumping is illegal in Queensland. The professional skydivers pleaded guilty in the Southport Magistrates Court and were fined A$750 without a conviction being recorded.
