Burj Dubai (Arabic: "Dubai Tower") is a skyscraper under construction in Dubai, and is the tallest man-made structure on Earth, despite being incomplete. Construction began on September 21, 2004, and it is expected to be completed and ready for occupation in September 2009. The total budget for the Burj Dubai project is about US$4.1 billion and for the entire new "Downtown Dubai", US$20 billion.
The projected final height of Burj Dubai is officially being kept a secret due to competition from other buildings under construction or proposed; however, figures released by a contractor on the project have suggested a height of around 818 m (2,684 ft)
Burj Dubai has been designed to be the centerpiece of a large-scale, mixed-use development that will include 30,000 homes, nine hotels such as the Burj Dubai Lake Hotel & Serviced Apartments, 3 hectares (7.4 acres) of parkland, at least 19 residential towers, the Dubai Mall, and the 12-hectare (30-acre) man-made Burj Dubai Lake.
