When we think about urban growth, our minds often go to skyscrapers emerging in already dense city centers, expanding suburbs, or new transit routes connecting once-distant zones. But what if the future of urban development isn’t about outward expansion or upward sprawl—but about radical linear precision?
This is exactly what Saudi Arabia’s newest visionary project proposes: a lineal city, a concept so bold and unfamiliar that it’s reshaping conversations in the fields of architecture, urbanism, sustainability, and futurism. But with innovation comes controversy, and this project—often compared with other global experiments in linear development—brings with it both admiration and skepticism.
As an architect and designer passionate about the future of cities and how design shapes our everyday lives, I find the Saudi Lineal City concept interesting—not only because of its technical and aesthetic ambitions, but also for what it symbolizes: a new take on ancient concepts, technological possibility, and the delicate balance between visionary thinking and human needs. However, at the same time, it makes wonder about the future lifestyle proposed and architectural implications in the long term. Let’s dive deep into this project to breakdown every detail and let you decide how you feel about it!
The Concept: What is Saudi Arabia’s Lineal City?
The Saudi Lineal City (formerly known as The Line under the NEOM initiative) is a bold urban development stretching across tens of kilometers in the desert, designed as a singular horizontal axis. Unlike traditional cities that sprawl outward, this linear city will house residential, commercial, cultural, and infrastructural functions in a compact and efficient manner, creating an interconnected urban ecosystem.
Spanning 170 kilometers and designed to accommodate 9 million people, The Line is part of Saudi Arabia’s larger NEOM project, continuing the country's trend of ambitious architectural ventures, following projects like the King Abdullah Financial District and the Kingdom Tower.
The city will feature:
Residential Areas: A mix of apartments and modular homes, designed to integrate with commercial and public spaces.
Commercial Spaces: Offices, retail outlets, and innovation hubs, aimed at attracting businesses in tech and sustainability.
Education: Schools, universities, and research institutions focused on developing a skilled workforce.
Healthcare: State-of-the-art medical facilities with AI, smart diagnostics, and telemedicine.
Transportation: The city will feature zero-carbon public transit, including autonomous vehicles and high-speed trains, designed within a car-free framework to ensure seamless mobility.
Green Spaces: Expansive green corridors will enhance walkability, with renewable energy sources and sustainable infrastructure incorporated throughout, fostering a healthy and eco-friendly urban environment.
Leisure: Malls, entertainment districts, and cultural centers for shopping and recreation.
Smart Infrastructure and Technology: The city will be powered primarily by renewable energy, aiming for a carbon-neutral footprint. AI-driven systems will manage energy, waste, and resources, integrating smart infrastructure and autonomous systems to create a sustainable and efficient urban ecosystem.
In other words, the city's design prioritizes efficiency, sustainability, and technology, offering a futuristic, interconnected living experience. Architecturally, The Line challenges traditional concepts of form, function, and scale, requiring a complete reimagining of how people interact with services, commute, socialize, and even perceive distance within a linear city structure.
Materials & Visual Identity
Outdoors: The Mirrored Façade
The most iconic feature of The Line is undoubtedly its mirrored façade, a bold, futuristic design statement that sets the tone for the entire project. Made of high-performance reflective glass and metal alloys, the façade is not just about visual drama. From an engineering standpoint, it plays a key role in deflecting solar heat and regulating internal temperatures, contributing to the project's sustainable ambitions.
From a design perspective, this mirror effect is not just a visual gimmick—it creates a dual experience: monumental from afar and immersive up close. It blurs the boundary between built and natural environments, reflecting the desert, sky, and light in a way that continually shifts throughout the day. As a designer, I find this duality fascinating—it challenges our traditional notions of façades as static surfaces and instead turns the building into a living visual interface.
Interior Materials: Sustainable and Smart
The interior construction also considers the project's commitment to sustainability and technological integration. Instead of relying solely on conventional materials, the approach focuses on flexibility, efficiency, and environmental responsibility:
Structural Core: This is a recycled steel and low-carbon concrete form the backbone of the interior framework. This minimizes embodied carbon while maintaining the strength and longevity necessary for vertical construction on such an unprecedented scale.
Natural and Renewable Elements: This is a Cross-laminated timber (CLT) and is used in non-load-bearing areas for its lightness and low environmental impact. Its warmth contrasts beautifully with the futuristic glass shell, bringing a sense of balance and tactile comfort to the interiors.
Modular & Prefabricated Components: Their interiors rely heavily on modular design and prefabricated panels. This not only speeds up construction but also reduces waste and allows for future disassembly or adaptation, an essential consideration in a project that aims for longevity in a rapidly changing world.
The contrast between sleek high-tech finishes and warm, natural elements creates interiors that are both efficient and human centric. There's an understanding here that sustainability isn’t just about numbers, it’s about creating spaces people can truly live in and connect with. I also believe the way The Line handles materials reveals a deep commitment to both engineering excellence and design ethics. It’s not about choosing between performance and aesthetics—it’s about weaving them together into a new typology of living.
Why This Project Is Controversial?
Despite all the good features and great offerings in terms of quality of life and sustainability, this project has rising some question among professionals and population in general, dividing the thoughts about this project. Some of the main concerns are:
Human Scale vs. Machine Efficiency
One of the primary criticisms is whether such a megastructure can remain human-centric. The lineal form might work well in theory, optimizing transportation and reducing urban sprawl, but it risks becoming sterile or dehumanized—a sleek system more suited to machines than communities. As architects, we know that beauty lies in the organic complexity of cities—intersections, plazas, uneven developments, and adaptive reuse. Can this level of spontaneity exist in a pre-designed, ultra-controlled linear form?
Environmental Irony
Though promoted as a sustainable project, critics highlight the irony of building a massive artificial city in a desert ecosystem. The ecological impact of constructing such a megastructure—including excavation, energy use in materials, and desert displacement—could contradict its green intentions. Sustainability needs to start from the materials and resources used during construction, not just the final product. If Saudi Arabia can achieve true circular construction methods and reduce embedded carbon, this might become a model city. But without transparency, skepticism is valid.
Social Equity and Accessibility
There’s also concern about who this city is really for. With Saudi Arabia’s rapid urban development often linked to economic diversification and global visibility, will this be a livable space for all income levels—or just a playground for elites? A city of the future should be inclusive. Housing, services, and public space must be accessible across socioeconomic classes, or the project risks becoming a glossy façade masking inequality.
Timeline: A Futuristic Vision in the Making
The Line is currently in its early planning and infrastructure implementation stages, with groundwork believed to have started around 2021. This phase includes environmental assessments, master planning, and coordination with architectural and engineering firms.
If everything moves forward smoothly, core construction could expand rapidly throughout the 2020s, starting with pilot zones focused on infrastructure, energy systems, and transportation networks. These early phases would act as a testing ground for the linear model.
The goal is to welcome initial residents by the early 2030s, with expansion continuing in phases throughout the following decade. Given the scale and ambition, full completion may extend well into the 2040s, much like other visionary projects in the region such as Masdar City or Lusail in Qatar.
Advantages of the Lineal City Concept
Beyond its bold visuals, the lineal city introduces several key urban strategies that could transform how we build, move, and live offering a glimpse into the future of city planning. Let’s explore a few of its advantages:
Spatial Efficiency
Traditional cities tend to sprawl outward, leading to inefficient land use, disconnected neighborhoods, and traffic-heavy infrastructure. In contrast, a lineal city organizes urban functions in a continuous, narrow strip—reducing fragmentation and overlapping services. By stacking vertical layers (residential, commercial, public amenities), it becomes possible to compress space without compromising functionality. From an architectural standpoint, this creates a unique opportunity to design multi-functional, flexible buildings that operate more like ecosystems than static structures.
Sustainable Transportation
One of the boldest claims of this concept is its potential to eliminate cars altogether. In a lineal format, public transportation systems—such as autonomous pods or high-speed electric trains—can be placed along a central spine, connecting every zone efficiently. This not only reduces greenhouse gas emissions, but also prioritizes walkability and accessibility, allowing residents to reach daily needs within a 5-minute walk. For urban designers and mobility planners, this is a dream canvas to rethink how we move and connect in the 21st century.
Technological Innovation
This city is not just about layout—it’s also a laboratory for smart infrastructure. Real-time data collection could guide everything from water use to traffic flow and energy distribution. Buildings may become responsive entities, adapting their performance based on weather conditions, occupancy levels, or user behavior. Artificial intelligence could optimize waste management, security, and maintenance. For architects and engineers, this is a step toward truly intelligent urbanism—a city that learns and evolves with its residents.
Architectural and Design Exploration
Designing a city with a fixed linear path challenges architects to push beyond traditional typologies. How do you keep a space engaging when stretched across a single axis? How can public space be designed to avoid repetition? Here lies the potential for groundbreaking ideas: modular living pods, kinetic facades that respond to solar orientation, adaptive shading systems, and highly localized microclimates. It’s a rare opportunity to blend environmental design, aesthetics, and cutting-edge tech in an entirely new setting.
A Future and its Potential Challenges
While the proposal is groundbreaking in many ways, it raises important questions about livability, functionality, and long-term feasibility that deserve closer examination. Let’s break down a few of them:
Monotony Risk
Linear cities run the danger of visual and spatial repetition. Imagine walking or commuting through kilometers of similar-looking buildings, without visual relief or varied scale. This could create a disorienting or even sterile experience. Breaking this pattern will require thoughtful rhythm in building heights, materiality, open spaces, and cultural nodes that introduce moments of surprise and identity along the journey. Just like traditional cities evolve around plazas, markets, and landmarks, the lineal city must develop its own vocabulary of variation.
Urban Isolation
One of the biggest social challenges is how to maintain community cohesion in a city that stretches tens of kilometers. Unlike circular cities where interaction radiates inward, a linear model may risk segmenting communities by distance. Even if transportation is fast, will it foster real human connection? How do people form bonds across that length, and how do neighborhoods maintain a sense of identity? This raises questions about spatial psychology, urban sociology, and how architecture can shape human interaction in non-traditional formats.
Heat and Climate Control
Saudi Arabia’s desert environment is harsh—scorching summers, sandstorms, and minimal rainfall. Creating comfortable and energy-efficient environments across such a long strip will require radical solutions in climate-responsive architecture. Passive cooling, innovative materials, integrated shading systems, and water recycling technologies will all need to work in harmony. Furthermore, how do you apply these consistently across 100+ kilometers without driving up costs or compromising quality? It's a serious technical challenge that will test material science and design ingenuity.
A Nod to Ancient Wisdom: The Lineal City and Indigenous Knowledge
What fascinates me most about this project is how, perhaps unintentionally, it echoes ancient planning patterns. While it appears hyper-futuristic on the surface, there’s something deeply familiar about the lineal city.
It reminds me of First Nations settlements, particularly those built along rivers. These communities were structured linearly—settlements hugging the riverbanks, optimizing access to water, transportation, and fertile land. This wasn’t just about convenience—it was an integrated lifestyle, where nature and human settlement coexisted harmoniously.
It’s captivating to see how, in a subtle way, the lineal city is reapplying this age-old logic. Only this time, the “river” is metaphorical—it’s a transit system, a green corridor, or a digital information stream. By stretching cities along a single axis, we reduce commuting time, promote walkability, and ensure that resources (real or digital) are never too far. In this way, Saudi Arabia’s project is both radically new and surprisingly ancient.
Defining the Future of Urban Living
Saudi Arabia’s Lineal City is more than just an architectural project, it’s a philosophical statement. It asks us to reconsider how we live, move, consume, and connect.But with that ambition comes responsibility: to create not just a beautiful city, but a livable one. Not just an efficient machine, but a community.As a designer, I am both skeptical and hopeful.
Skeptical because we’ve seen futuristic cities that overpromise and underdeliver. But hopeful because, when executed thoughtfully, this project could redefine what’s possible—not just for Saudi Arabia, but for a planet struggling with climate crisis, overpopulation, and unsustainable growth. And maybe, just maybe, by looking forward, we’re also reaching back—honoring the wisdom of Indigenous communities who built along rivers, understood natural cycles, and lived lineally not because it was futuristic, but because it was intuitive.
In the end, the real question isn’t whether we can build a city in a line. It’s whether we can build a future worth living in—one that improve human experience through architecture.
