The new world's tallest building opens officially on Monday in Dubai with 160 storeys and 828 meters high.
The tower has been named the Burj Khalifa after the ruler of the emirate of Abu Dhabi, whose bailout helped Dubai's biggest developer avoid a potentially disastrous debt default in November.
The building's owners say more than 90 per cent of space has been sold. It boasts four swimming pools, a private library and a hotel.
The tower and surrounding development has cost about $22 billion to build.
