The Mukaab (Arabic: المكعّب, romanized: mukaʻʻab, lit. 'cube', [mukaʕʕab]) is a proposed architectural project to build a 400-meter (1,300 ft) tall cube-shaped skyscraper in the al-Qirawan district of Riyadh, Saudi Arabia, one of the five neighborhoods of the planned real estate development of New Murabba. Launched in February 2023, its cuboidal layout and design are inspired by the Murabba Palace.[1][2][3]
The interior as currently planned will feature enormous holographic projections aimed at making viewers feel as if they are in different realities, times, and places. The interior will also feature a swirling tower for observation decks and restaurants, from which the projections will emanate.[7]
The Mukaab is planned to be the centerpiece of a giant new downtown built within the Saudi capital city of Riyadh called New Murabba. It will be the world's largest single-built structure with around 2 million square metres (22 million square feet) of interior floor space.[8][9][5][10]
The project will be undertaken by the New Murabba Development Company of which Crown Prince Mohammed bin Salman is the President.[11]
The cube is intended to be 400 meters (1,300 ft) tall and 400 meters (1,300 ft) wide on each of its four sides.[12]
