The team at NEOM has already begun construction on Saudi Arabia‘s ‘zero-gravity’ city THE LINE. The group is reimagining how a city is built, and what sort of life is possible within its mirrored walls. The colossal scale of the proposal has never been seen and its concentrated proportions unheard-of. THE LINE is a rejection of the sprawling suburb and a hyper-exaggeration of the supertall skyscraper. Often referred to as a ‘groundscraper,’ the singular structure will stretch 170 kilometers — over one hundred miles — to house a city of nine million people.
