Eureka Tower

Eureka Tower is a 300 metre skyscraper located in the Southbank precinct of Melbourne, Victoria, Australia. Construction began in August 2002 and the exterior completed on 1 June 2006. The plaza was finished in 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. The developer of the tower was Eureka Tower Pty Ltd, a joint venture consisting of Daniel Grollo, investor Tab Fried and one of the Tower architects Nonda Katsalidis. The details of Eureka Tower is explained in world tour guides below. It was the world tallest residential tower when measured to its highest floor, until surpassed by Ocean Heights and the HHHR Tower in Dubai. It is now the fourth tallest, after Q1 located on Queensland s Gold Coast and the two Dubai skyscrapers.

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.

When measured either by the height of its roof, or by the height of its highest habitable floor, Eureka Tower was the tallest residential building in the world when completed. It is also currently the building with the most floors available for residential occupancy in the world. 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 second-tallest building in Australia and the tallest building in Melbourne. The single level basement and first 9 floors contain car parking. The building's proximity to the water table as well as the Yarra River made the construction of a basement car park uneconomical. There are a total of 84 floors of apartments with the remainder being used for building facilities and the observation deck.

According to the ranking system developed by the U.S.-based Council on Tall Buildings and Urban Habitat, the Eureka Tower qualifies as the tallest building in one of the four categories in which heights are ranked, namely height to the floor of the highest occupied floor of the building. For comparison, the Q1 apartment tower on the Gold Coast has its highest habitable floor the observation deck, reaching a height of 235 m, some 62 m lower than Eureka Tower's highest habitable floor. Q1's highest penthouse apartment is 217 m whilst Eureka's penthouse is 278 m high. However, the spire attached to the top of Q1 exceeds the Eureka Tower in the other two categories, namely Height to the tip of spire, pinnacle, antenna, mast or flag pole in this case, spire and height to architectural top of the building.

The tower was built using reinforced concrete using a slipform method. Eureka Tower's lift core superseded the height of Rialto Towers on 9 November 2004. On 23 May 2006, the crane on top of the tower was dismantled by a smaller crane, which was dismantled by a smaller crane that could be taken down the service elevator. Eureka Tower has 24 carat gold plated glass windows on the top 10 floors of the building. Installation of the gold glass was completed in March 2006. Apartment owners and tenants had taken up residence in the building between Ground Level and Level 80 as of July 2006.

The Summit Levels contain only one apartment per floor: each apartment had an original price tag of A$7 million just for the empty space; purchasers were required to fit out the apartment at additional cost. On 11 October 2006, the tower was officially opened by then Victorian Premier, Steve Bracks. The Eureka Tower has been made to be able to withstand high winds and major earthquakes seeming they are the two riskiest events that the city faces. The tower is supposed to sway in the event of such things. The observation deck 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, the Sky Tower in Auckland, New Zealand having higher views. It opened to the public on 15 May 2007. An entry fee applies to access the Skydeck.

The Skydeck features thirty viewfinders that help visitors to pinpoint numerous significant landmarks around all parts of Melbourne, along with several free binoculars. There is a small outside area called The Terrace which is closed in high winds. There is also a glass cube called The Edge, which extends itself from the building to hang over the edge of the tower and add to the viewing experience. On 10 January 2005, Grocon, the firm building Eureka Tower, proposed adding a 53.8 m communications mast or observation tower. The proposal is currently before the local planning commission. This mast would be a significant structure, used for providing an adventure climb to the tip of the summit.

On 16 April 2006, a new proposal was announced that the construction company and developers were considering options for the building to have a skywalk that would take daring people up 350 metres high. The proposed structure may also house a communication tower. Skydeck 88 features 'The Edge' - a glass cube which projects 3 m out from the building with visitors inside, suspended almost 300 m above the ground. When you enter, the glass is opaque as the cube moves out over the edge of the building. Once fully extended over the edge, the glass becomes clear.
