The Burj Khalifa, located in Dubai, UAE, claimed the title of the world’s tallest building in 2010 and has held the record ever since. This magnificent structure, which began construction in 2004, took six years to complete and was designed to accommodate a range of commercial, residential, and hospitality ventures. With a total height of 829.8 m (2,722 ft), or just over half a mile, no other building worldwide has surpassed the Burj Khalifa’s impressive stature.
Since April 1st, 2013, a construction project has been in progress in Jeddah, Saudi Arabia. This ambitious project involves the construction of the Jeddah Tower, which is set to exceed the Burj Khalifa in height and become the world’s first building to reach the 1 km (3,281 ft) milestone. Meanwhile, in various locations worldwide, construction of other exceptional skyscrapers is also underway, each showcasing distinctive and captivating features.

The building was designed by Adrian Smith, the same American architect who designed the Burj Khalifa.
