The Line — a key part of Saudi Arabia’s Neom project — is a visionary but flawed concept, urban planners say

Saudi Arabia is constructing a huge mirrored city in the desert called The Line. The parallel skyscrapers planned to stretch for just over 100 miles and accommodate millions of people.
The project is one part of Neom, the kingdom’s ambitious venture that is a key element of Vision 2030 — the plan to help diversify its oil-dependent economy.
Neom was dealt a blow on Tuesday when its board announced that CEO Nadhmi al-Nasr had stepped down after six years in the role, without elaborating. Aiman Al-Mudaifer, an executive in the Saudi Public Investment Fund, was named acting CEO.
Reports earlier this year suggested that The Line had been scaled back — claims denied by ministers. Yet even a far smaller-than-imagined version of the project would be the largest linear city ever built.
The concept of linear living is “ambitious but hardly revolutionary,” Anirban Adhya, a professor of architecture and urban design at Lawrence Technological University in Michigan, told B-17.
Following the Industrial Revolution, many urban planners looked to alternative city layouts to tackle booming populations.
The Spanish architect Arturo Soria is widely credited with designing the first linear city, “La Ciudad Lineal,” in 1882 on the outskirts of Madrid. Some 40 years later, in 1924, renowned Swiss-French architect Le Corbusier offered another radical alternative with his “Ville Radieuse,” a linear, ordered metropolis full of green space.
The Soviet urbanist Mikhail Okhitovich was sent to a gulag in 1930 for his “economically crippling” proposal to transform the city of Magnitogorsk into eight ribbon-like strips converging on a factory.
“It has been common for urban planners to argue for a new future as a reaction to what they claim to be an ‘unsustainable’ — existing situation of their time. The Line in Neom is no different,” said Adhya.
But revolutionary or not, is the idea of building a dense metropolis in the shape of a line a good one?
Proposals show “The Line” stretching across the northwestern region of Tabuk, Saudi Arabia.
Compared to traditional layouts, the benefits of linear cities include efficient public transport, ready access to nature, and a more egalitarian lifestyle. Theoretically endless, they can easily extend as populations expand.
Proposals for The Line echo many of these promises. Its website presents the city as a solution to mass urbanization and the climate crisis, depicting it as a sustainable carless utopia that will preserve 95% of the region’s land.
Neom’s designers claim that all essential services will be accessible within five minutes, and nature will be just a two-minute walk away. AI-powered technology throughout the city will enhance sustainability and maximize residents’ life expectancy, they say.
“There is no right shape for a city — they typically evolve over time, based on natural, cultural, transportation, political, and economic factors,” Mona Lovgreen, a partner at international architecture firm DIALOG, told B-17
She believes that if designed correctly, The Line’s linear form would make it accessible and facilitate the integration of renewable energy sources along its entire length.

Though she said its goals may be exaggerated, Lovgreen believes the vision of The Line is admirable. “It challenges us to rethink urban design and discover new ways to make cities efficient, livable, and sustainable.”
It could set a trailblazing example for how to use AI to improve sustainability and energy efficiency, something US urban planners should replicate, Lovgreen added.
The focus on convenience and services being within reach also shows promise, Adhya said, pointing to successful examples already underway in cities like Paris and Portland.
In “smaller chunks and pieces,” the linear structure of The Line could work, Adhya said.
‘Bland and monotonous’
While some practical sides of the structure have potential, the experts B-17 spoke to saw fundamental issues with the lived experience inside linear cities.
“The Line could be a fascinating place to visit and experience, but I’m still unsure of whether humans are designed to live in such a rigid and prescriptive structure,” Lovgreen said.
The Line is formed of modules that can each house 80,000 people, able to move about through a horizontal and vertical transport system.

“Compared to other urban designs like grid layout, radial layout, ring layout, or some combination of these, human experience in a strictly linear urban development can lack interest and variation,” explained Adhya.
“Certain parts of the city could become too far and segregated.”
The repetition of infrastructure and kit-of parts would be “bland and monotonous,” lacking the unique character that other cities offer, said Lovgreen.
“Ultimately, the psychological impact of living in such a regimented environment may affect residents’ well-being,” she told B-17.
This type of structure is not only monotonous, but can limit social cohesion, according to John Gold, professor of urban historical geography at Oxford Brookes University in the UK.
“Linear cities are an extreme form of urban dispersal — community development and social cohesion still need centrality,” Gold told B-17.
Another challenge in Neom’s design is its over-reliance on technology and the public transport system, experts said. If something went wrong, the entire system would crumble, they warned.
“Most cities have network redundancy, where multiple options are available if a specific connection or intersection is blocked. A linear city may not have this capability,” explained Lovgreen.
The site of Neom in Saudi’s Tabuk province is on a migration route used by billions of birds.
Lastly, in spite of The Line’s proclamations of sustainability, its huge mirrored walls could be harmful ecologically both in terms of unnecessary heat gain within the structure as well as being detrimental for the migratory flight paths of billions of birds.
But the big issue, Gold asks, is “who would actually want to live in such a ‘city’? These schemes, and the Saudi one is a classic example, map out a hi-tech utopian future but never engage with people as they really are. In my opinion, linear city schemes are best left as design exercises for third-year architectural students.”
