World’s Largest Building Begins in Saudi Arabia: Meet the Mukaab

In a groundbreaking move for both engineering and architecture, Saudi Arabia has started construction on what will be the world’s largest building — the Mukaab. Located in Riyadh, this $50 billion cube-shaped structure is set to redefine urban spaces, aiming to be a self-contained mini-city offering everything from fine dining to residential units. The Mukaab, which will reach 1,300 feet in height and 1,200 feet in width, is spacious enough to fit 20 Empire State Buildings within its walls.

Despite its modernity, the Mukaab draws inspiration from traditional Najdi architecture, incorporating elements such as rectangular windows and centralized courtyards. Designed to echo the natural landscapes of the region, the Mukaab’s surroundings will resemble dry riverbeds, known as wadis, adding a touch of local ecology to this ultra-modern space. The massive structure will boast 2 million square feet of space, featuring 104,000 residential units, 9,000 hotel rooms, and a variety of green spaces accessible within 15 minutes from any point inside.

The Mukaab isn’t just an architectural marvel; it’s also a key part of Saudi Arabia's “Vision 2030” initiative led by Crown Prince Mohammad bin Salman. This project aims to diversify the Kingdom’s economy beyond oil, creating 334,000 jobs and adding over $51 billion to non-oil GDP. The use of artificial intelligence in the building will create immersive experiences for visitors, while massive digital screens on the structure’s exterior will further enhance its futuristic appeal. Completion of the Mukaab is expected by 2030, setting a new benchmark for sustainable urban design.
