Dubai has stunned the world with its audacious and striking architecture, from its sail-like Burj Al Arab hotel to its three palm-shaped man-made islands now under construction, The Palm Jebel Ali, The Palm Jumeirah and The Palm Deira. As the United Arab Emirates sheikdom works towards its ambitious plan of becoming the world's business and tourism hub, its skyline is to undergo dramatic changes. If you think an apartment in The Arch near Kowloon Station in Hong Kong is spectacular, how about an apartment in an 80-storey skyscraper that spirals 90 degrees? Infinity Tower will be built on Dubai's waterfront by 2008. Every floor rotates by 1.2 degrees while the floor plate remains consistant. 'The building of the tower is very challenging because, architecturally, it has never been done before,' said Sarah Derbas, sales and marketing manager with Palma Real Estate, the developer building the Infinity Tower. The tower will have 450 apartments and units will be offered for sale in Hong Kong this weekend. All the apartments will have floor-to-ceiling windows and marble and wood finishings. The race is on among developers in Dubai to out do each other by building the next big thing architecturally, according to Ms Derbas. 'This trend will keep on going,' she said. 'In Dubai, everyone is thinking about building the biggest and the tallest. So we need to do something special or else it will be difficult to sell.' A typical example of this mindset can be found in the Burj Dubai, being built by the region's biggest developer, Emaar Properties. The project, comprising residential and commercial space and a hotel, will be the world's tallest building at more than 800 metres when it is finished in 2008. While the building may appear futuristic, architect Adrian Smith was inspired by traditional Islamic architecture and a plant widely cultivated in the region. The form of the elegant Hymenocallis, or spider lily, is one of the organising principles in the tower's design.
