If you have a fear of heights, you might want to avoid the Burj Dubai -- once completed, the tower will have 160 floors, and will almost reach a half  of a mile, into the sky.

Over the weekend, the Burj Dubai (burj is the arabic word for tower) became the world's tallest tower. The Burj Dubai is now a few meters higher than the 508 meter tall Taipei 101 tower, which was, since 2004, the world's tallets tower. Construction of the Burj tower is expected to wrap up around the end of 2008.

Construction of the United Arab Emirate's Burj Dubai only began in 2004. The entire structure is worth about a billion dollars, and was financed by a consortium lead by Samsung Corporation. Construction of the tower is rapid. At times, floors have been built in periods as short as three days. Most of the labor for the project has been supplied by Indian immigrants, working around the clock for no standard minimum wage, in the desert heat of Dubai.

The tower is going to boast 56 elevators, ultra-luxurious apartments, spas, boutiques, the first Giorgio Armani-edition hotel, a observation platform on the 124th floor, four big swimming pools, a 15,000 square foot gym, a library, restaurants, a Cigar Club smoking lounge, offices, and residential units.

The tower's water system is designed to supply a 946,000 liters of water a day. Additionally, the tower will have one of the world's most extensive building cooling system, to keep things comfortable. All those air conditioners will be needed, because at peak capacities, it is estimated that as many as 35,000 people might be in the tower at once.
