Burj Khalifa, formerly known as Burj Dubai, is a skyscraper in Dubai, United Arab Emirates, and the tallest man-made structure ever built, at 828 m. The design incorporates ideas from traditional Islamic architecture, while the open petals of a desert flower were the inspiration for the tower’s base. Burj Khalifa will be home to 1,044 luxury apartments, 49 floors of offices and eventually a 160-room Armani-branded hotel. Around 12,000 people are expected to live and work in the tower, which is part of a 500-acre development.
