In a new 45-minute documentary, well-known architects have provided insight into the thought process behind The Line, a megacity that is currently in the planning stages.

Recently, the Discovery Channel published a documentary called “The Line: Saudi Arabia’s City of the Future in NEOM.” The documentary showcased the contribution of architects Thom Mayne, Peter Cook, and Roger Soto, as well as Saudi Arabia’s Crown Prince, Mohammed bin Salman on NEOM’s The Line.

A linear smart city called “The Line” is currently under construction in NEOM, Tabuk Province, Saudi Arabia. The Line was created to accommodate around 9 million people and spans across 34 square kilometers. The total cost of the project is $500 billion. The residents will be able to reach all the amenities within walking distance, and there is also a high-speed rail for a 20-minute commute. The project was thoughtfully designed to ensure that the facilities are easily accessible within a 5-minute walk for the residents.

“They say a lot of projects in Saudi Arabia can’t be done, they’re too ambitious,” Mohammed bin Salman said in the documentary. “They can keep saying that and we can keep proving them wrong.”
