Burj Khalifa

Burj Khalifa , known as Burj Dubai prior to its inauguration, is a skyscraper in Dubai, United Arab Emirates, and is the tallest man-made structure in the world, at 829.8 m (2,722 ft).

Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010,and is part of the new 2 km²  development called Downtown Dubai at the 'First Interchange' along Sheikh Zayed Road, near Dubai's main business district.

In March 2009, Mohamed Ali Alabbar, chairman of the project's developer, Emaar Properties, said office space pricing at Burj Khalifa reached US$4,000 per sq ft (over US$43,000 per m²) and the Armani Residences, also in Burj Khalifa, sold for US$3,500 per sq ft (over US$37,500 per m²).He estimated the total cost for the project to be about US$1.5 billion.

The project's completion coincided with the global financial crisis of 2007–2012, and with vast overbuilding in the country; this led to high vacancies and foreclosures.With Dubai mired in debt from its huge ambitions, the government was forced to seek multibillion dollar bailouts from its oil-rich neighbor Abu Dhabi. Subsequently, in a surprise move at its opening ceremony, the tower was renamed Burj Khalifa, said to honor the UAE President Khalifa bin Zayed Al Nahyan for his crucial support.
