Tallest Residential Building to the Roof - Eureka Tower

Date of Record: 11/10/2006

Eureka Tower is a 297.3-metre (975 ft) skyscraper located in the Southbank, Melbourne. Construction began in August 2002 and the exterior completed on 1 June 2006 and the building was officially opened on 11 October 2006.

The project was designed by Melbourne architectural firm Fender Katsalidis Architects and was built by Grocon (Grollo Australia). Eureka Tower is named after the Eureka Stockade, a rebellion during the Victorian gold rush in 1854. This has been incorporated into the design, with the building's gold crown representing the gold rush and a red stripe representing the blood spilt during the revolt. The blue glass cladding that covers most of the building represents the blue background of the stockade's flag and the white lines also represent the eureka stockade flag. The prospectus of the building suggests the white horizontal stripes represent the marking units on a surveyor's measuring staff.

The building stands 297 metres in height, with 91 storeys above ground plus one basement level. It is one of only seven buildings in the world with 90 or more storeys and is the 50th tallest building in the world. It is also the tallest residential building in Australia to the roof. The observation deck (Eureka Skydeck 88) occupies the entire 88th floor of the Eureka Tower and is the highest public vantage point in a building in the Southern Hemisphere at 285 m (935 ft).

The facade consists of glass and aluminium panels covering an area of 40,000 square metres. The glass on the top 11 floors is 24 carat gold infused. The Tower used 110,000 tonnes of concrete and weighs 200,000 tonnes. The building consists of 92 storeys and 3,680 stairs. The top of the tower can flex up to 600mm in high winds. Two 300,000 litre water tanks on level 90 and 91 help to dampen the oscillations.
