Q1 View of the Gold Coast From the 77th Floor

Q1 is the Worlds Tallest Residential Building
78 Floors with a lift that takes 42 seconds to reach the 77th Floor where the Viewing Area was located

At 322.5 m (1,058 ft) and with a roof height of 275 m (900 ft), Q1 qualifies as the world's tallest all-residential building when measured to the top of its structural point (spire), but is the world's second tallest behind Melbourne's Eureka Tower (roof height of 297.3 metres, 975 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 criteria in which heights are ranked is to the top of the spire, therefore Q1 qualifies as the taller.

It is currently 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.

Q1 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.

It 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 then up to four metres into solid rock.
