Mukaab would have risen to an impressive height of 400 m (1,312 ft) in the Saudi capital Riyadh. More importantly, it would also have been just as long and wide as it is tall. This would make it able to theoretically fit 20 Empire State Buildings inside of it and cement its status as the world's largest – though not tallest – skyscraper.

The design of the cuboid building's decorative exterior riffed on traditional Islamic architecture, while its interior would have had a floorspace of around 2 million square meters (0.77 square miles). At its center was to be another large twisting tower. Excavation work was nearing completion as of late 2024 and 10 million cubic meters (roughly 350 million cubic ft) of earth had already been removed.
