In 2004, construction began on a new building in Dubai, promising a revolutionary design that would dwarf the rest of the world's skyscrapers. Five years later, the 828-meter Burj Khalifa was complete, surpassing the previous record-holder by over 60%. What innovations allowed for such a huge leap in height? Alex Gendler digs into the architecture of this unprecedented project. [Directed by WOW-HOW Studio, narrated by Addison Anderson, music by Stephen LaRosa].

How the world's tallest skyscraper was built

The Burj Khalifa's leap in height was enabled by a tubular design and exoskeleton, revolutionizing skyscraper engineering.

Innovative buttressed core design in the Burj Khalifa disperses wind forces, allowing it to stretch 163 floors into the sky.

Behind the Burj Khalifa's marvel, a narrative of harsh labor conditions emerges, highlighting the human cost of architectural feats.
