Saudi Arabia has begun construction on The Mukaab, a 400-meter-tall cube-shaped building worth $50 billion. If completed, it will be the world's largest structure, with two million square meters of floor space. The building is designed as a "premium hospitality destination" and will be available for retail, corporate, and cultural uses.
The project is part of Saudi Arabia's Public Investment Fund (PIF) and will be constructed by New Murabba Development Company (NMDC). The district where the building will be located, New Murabba, will have over 25 million square meters of floor area and comprise 104,000 homes.
The Mukaab is part of Saudi Arabia's efforts to create innovative infrastructure. The country has also conceptualized projects like The Line, a mirrored city in the desert, and the Jeddah Tower, which was designed to be the world's tallest skyscraper.
