Future Cities: The Latest Architecture and News

The future of urban planning and architecture is promising if the world, collectively, looks beyond the concept of mere sustainability and instead embraces a nature-positive approach. As global population growth drives rapid urbanization—requiring humanity to build the equivalent of a city the size of Madrid every week for decades to come—the construction sector faces a defining challenge: how to build durable, energy-efficient, and resilient urban environments in harmony with natural ecosystems. 

Cities today are being reimagined as living, evolving organisms, combining digital intelligence, ecological systems, and new materials to shape radical futures. At Carlo Ratti's "Intelligens. Natural. Artificial. Collective." biennial, over 750 participants challenge established boundaries between architecture, landscape, and technology. Several conceptual projects showcased in the main exhibition challenge conventional boundaries between architecture, landscape, and technology. From bio-adaptive urban systems and Martian water-based settlements to immersive symphonies of satellite data, these works collectively envision new models for cohabitation, resilience, and planetary awareness.

This month's Unbuilt selection presents six speculative projects, presented as part of the 2025 Venice Architecture Biennale exhibition, as provocations for rethinking the future of cities and human settlement. While some proposals transform architecture into self-sustaining, living infrastructures, others explore how data and sensory interfaces can redefine our relationship with natural and urban environments. Together, they offer a cross-section of how architects and designers are using unbuilt work to imagine new possibilities for life on Earth and beyond.

From greenhouse gas emissions and air pollution to deforestation, one of the leading contributors to global warming today is emissions from the transportation sector. Exploring its origins and evolution, as well as the major challenges it faces, the development of electric mobility in urban environments represents a global transition that requires a coordinated mix of policies and actions to achieve cleaner and more sustainable transportation systems. Designing safe and comfortable infrastructure for walking and cycling, promoting public transit and shared mobility, and designing more efficient streets that include electric vehicles, among other actions, are part of a growing worldwide effort to reduce carbon emissions.

What structures and infrastructures sustain the ties and relationships between the countryside and the city? How will architecture and emerging technologies maintain -or not- the coexistence of both worlds in the future? The reduction of ecological footprints, the impact of climate change, the decentralization of major cities, food security, and other contemporary issues challenge professionals in architecture and urbanism globally under the main shared goal of improving citizens’ quality of life and achieving physical, mental, and emotional well-being in both built and natural environments.

In early 2021, Saudi Arabia unveiled the Line, a 170-kilometer-long linear city, part of the NEOM project. NEOM has since expanded with proposals for the region, including a ski destination set to host the 2029 Asian Winter Games, a floating port city at Oxagon, and cliffside hotels at Leyja. However, the Line continues to be one of the most debated of the proposals due to its scale and unprecedented design. According to the official releases, the city would measure 170 kilometers in length, 200 meters in width, and 500 meters in height, making it the 12th highest skyscraper in the world. In its final phase, it is expected to welcome 9 million residents, nearing the size of London or New York’s five boroughs.

On October 23, 2023, during the closing of the Line Exhibition in Riyadh, Saudi Arabia, ArchDaily’s Editor in Chief, Christele Harrouk spoke to Tarek Qaddumi, Executive Director of The Line Design at NEOM, asking questions that probe into both the conceptual aspects and the technicalities of The Line project. In this video interview, the conversation addresses notions such as accessibility, transportation, and sustainability, while also exploring the concept of Cognitive Cities and the intended phasing of the project.

We’re all familiar with the plot of a movie that occurs in a city still standing in a post-apocalyptic era. The streets are empty, except for a few survivors who wander aimlessly, searching for signs of life. Buildings begin to crumble and rust away after years of neglect, public transportation sits idle, and overgrown weeds spring from the cracks in the unmanaged sidewalks and streets. The scene feels eerie because we can’t imagine letting our physical environment sit in decay. It seems impossible that our built environments where we live and work each day suddenly fall silent. It’s a city without a pulse.

“We shape our buildings; thereafter they shape us.” Despite Winston Churchill’s words, architects are shaped by our culture, and our work reacts to it. Because our culture evolves, the practice of architecture evolves. What is “New” in architectural practice has had accelerating change, exploding in the 21st century because new technologies have changed everything on a level of the Industrial Revolution, 200 years ago.  

We are still at the dawn of the Metaverse, the next wave of the Internet. The current “mainstream” Metaverse platforms serve as experimental containers to host the wildest dreams of virtual worlds where we are supposed to unleash the imagination. However, from a spatial design perspective, they have so far been lame and ordinary. Without the constraints in the physical world, how do we draft the urban blueprints in the metaverse? I believe metaverse planners can find inspiration from Italo Calvino’s Invisible Cities, in which he revealed a poetic and mathematical approach to “urban planning” in the imaginary worlds.

Nike recently acquired RTFKT, a design studio that was founded in Jan 2020, and is known for its virtual “metaverse-ready sneakers and collectibles”. Metaverse land purchases are making headlines with multi-million dollar price tags. We’ve also seen mainstream adoption for NFT art this year and the sales are expected to surge to $17.7 billion by the end of 2021.

Beneath the hype and frenzy, we can spot a fundamental shift that unlocks a new creator economy. It provides the creators with direct access to the market, builds ongoing relationships with fans, and unites strangers in self-governed communities. In this article, we will discuss why every 3D designer/architect should embrace the Web 3.0 movement to adopt a new business logic and benefit from the creator economy in the metaverse?

You might have heard that Mark Zuckerberg wants Facebook to become a Metaverse Company, and earlier this year, Epic Games, the company that develops the Unreal Engine announced that it completed a 1 billion round of funding to support the long-term vision for the metaverse. Metaverse is definitely the hottest buzzword in the tech scene. In this article, we will briefly discuss what is Metaverse, who will build it, and most importantly why it matters for architects, and how can designers play a significant role in this upcoming digital economy?
