UNS's design proposal for Turin's new Metro Line 2, developed in collaboration with Settanta7, Mijksenaar, Frigorosso, 3BA, and WSP, has been selected by an international jury of experts chaired by Dominique Perrault. The proposal is based on the idea of "flow," a concept that has historically shaped the Italian city, from the Po and Dora rivers to the 18 kilometers of arcaded porticoes that structure how residents and visitors move. The project envisions Line 2 as a new "urban river," guided by three design principles to facilitate this flow: branding, transit experience, and scales of identity. With 32 stations planned in total, the initial design phase includes 10 stations, among them Mole Giardini, San Giovanni Bosco, and Carlo Alberto.
In Iran's capital, Tehran, movement defines the city. Each day, millions navigate a landscape shaped by highways, traffic corridors, and dense urban blocks. Over decades of rapid expansion, infrastructure has become the dominant language of development. Streets prioritize vehicles, sidewalks function as narrow conduits, and many public spaces operate primarily as passages rather than places of gathering. Across parts of West Asia, ongoing conflict has also reshaped the region's urban landscapes, where significant architectural environments have been damaged or transformed. Within this broader context, the preservation and creation of everyday civic space becomes increasingly meaningful. Recognized with the Aga Khan Award for Architecture, the Jahad Metro Plaza project, designed by KA Architecture Studio, demonstrates how modest infrastructural interventions can reshape the civic life of a city.
The metro network plays a central role in Tehran's daily life. It connects distant districts and sustains the rhythms of the metropolis. Yet the places where the underground city meets the surface are rarely conceived as civic environments. Metro entrances typically appear as fragments of infrastructure: stairs descending below ground, surrounded by railings, kiosks, and improvised circulation paths. They function efficiently as thresholds, but seldom as places to remain.

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.
In March 2023, the AustinTransit Partnership (ATP) announced the selection of UNStudio, HKS, and Gehl to lead the architecture and urban design of Project Connect, an expansion of Austin's public transportation system in Texas, United States. Led by ATP, the system aims to connect communities, enhance public spaces, and integrate with the city's evolving urban fabric. The design framework, developed by the four entities, establishes the foundation for how the light rail will interact with Austin's neighborhoods. The design team states that the project's priorities are in people-first infrastructure and the creation of dynamic public spaces, which they seek to reflect in the newly unveiled images. As a voter-approved initiative, Project Connect actively encourages public participation, allowing Austin residents to provide feedback throughout its development.
New York City has implemented the first congestion pricing scheme in the US, charging drivers up to $9 per day to enter a designated zone south of Central Park, encompassing areas like Times Square and Wall Street. The initiative aims to alleviate chronic traffic congestion, improve air quality, and generate revenue for public transportation improvements, addressing New York City's ranking as the world's most congested urban area for two consecutive years. The plan went into effect Sunday, January 5th, 2025.
The Royal Institute of British Architects (RIBA) has announced the Elizabeth Line, designed by Grimshaw, Maynard, Equation, and AtkinsRéalis, as the winner of the 2024 RIBA Stirling Prize. Since its inception in 1996, the prestigious annual award sets out to recognize UK's best new architecture. Named in honor of Queen Elizabeth II, the Elizabeth Line represents an important development for London's transportation network. Connecting Reading and Heathrow to Essex and South East London, the development spans 62 miles of track and 26 miles of tunnels, a complex and expansive undertaking accommodating 700,000 passengers every weekday.
The team led by Henning Larsen, in collaboration with Ramboll, Cistri, Gehl, Participate in Design, and Camphora has won the commission for the master plan consultancy to design Singapore’s North-South Corridor’s surface streets. The project proposes an expansive urban transformation, aiming to integrate public transport, active mobility, community-focused spaces, and greenery along the 21.5km corridor. Local communities and stakeholders are also actively engaged in the design process through public engagement sessions. The initial master plan design is set to continue into 2026, over the next 18 months.
Recent news headlines from the African continent show a variety of urgent issues affecting urban centers: severe flooding threatens Kenya's capital, Nairobi; the light rail system in Addis Ababa, Ethiopia, is faltering after a successful start. Meanwhile, in Egypt's capital, Cairo, new infrastructure and housing expenditures proved too steep and necessitated a government bailout. African cities face a plethora of problems but they also hold the potential to improve countless lives. As South America shares stark similarities in its history with that of Africa, it could provide both a point of reference and a positive example for tackling these concerns at an urban level.
CityMakers, The Global Community of Architects Who Learn from Exemplary Cities and Their Makers, is working with ArchDaily to publish a series of articles about Barcelona, Medellin, and Rotterdam. The authors are the architects, urban planners, and/or strategists of the projects that have transformed these three cities, which are visited in the "Schools of Cities" and studied in the "Documentary-Courses" made by CityMakers. On this occasion, Alejandro Restrepo Montoya, Director of Urban Planning and Architecture of Medellín, presents his article "Environmental Urbanism and Urban Geographies, Medellín 2024-2027"
Medellín's urban plan focuses on answering how urban planning can improve people's quality of life. By developing its proposal, the city is promoting the social benefits that these urban planning practices can generate. Medellín emphasizes the use of natural and environmental conditions, such as valleys, streams, rivers, mountains, and hills, to develop urban planning criteria that address social needs.
As part of public ‘open house’ sessions with local communities and agencies, Foster + Partners and Arup have revealed the design for the first 4 stations of California’s High-Speed Rail. This is part of an extensive project, as the new Central Valley stations will serve as models for the design of the next stations planned along the 500-mile-long Los Angeles/Anaheim to San Francisco rail system. The open house sessions represent an opportunity for the public to explore the project, talk with California High-Speed Rail Authority planning experts, and learn more about the high-speed rail infrastructure. The project is under construction, with the first operable line scheduled to be completed between 2030 and 2033.
Bjarke Ingels Group and A+Architecture have revealed the design for the 12,000-square-meter Marengo Multimodal Transport Hub in Toulouse, France. The project will expand the functionality of the city’s central station, Gare Matabiau, strengthening the area’s public transport networks by creating a hub for bus, railway, and metro, all connected under one roof. The design of the new hub takes cues from the city’s distinctive roofscape and the traditional use of the rose-colored “foraine” brick, employing a mass timber structure and low-carbon concrete to ensure a sustainable intervention adapted to its environment. The Hub is set to begin construction in 2026.
Urban mobility in the United States has seen a radical transformation with the introduction of ridesharing services in the late 2000s. The widespread adoption of services such as Uber and Lyft has altered the way citizens move around cities, offering convenience, flexibility, and accessibility like never before. The innovative business model that excels at designing for individual users failed to foresee larger implications at the scale of the city - congestion, public transit systems, and car ownership. While European countries such as Brussels have pledged to encourage public transportation to curb traffic congestion issues, American cities hunt for solutions of their own.
The project for implementing a fourth metro line in the Greek capital began in 2021, with the purpose of reducing the need for automobiles in the crowded city. As the 15-station new line is estimated to transport 340,000 passengers a day, up to 53,000 cars could be taken off the roads each day. While the opening of the line may be five years away, work has now begun to refurbish seven urban squares which will become stations. Despite public support for the initiative, the project has also led to some controversy, with residents fearing gentrification.
MAD Architects has announced the completion of the Jiaxing Train Station, the first transportation infrastructure project developed by the architecture office. Located in the historic city of Jiaxing, 100 kilometers southwest of Shanghai, the project involves the replacement of a dysfunctional station that had stood at the site between 1995 and 2019. As China has developed significantly in terms of urbanization, its train stations have grown into complicated, widespread, and uninviting infrastructures. Through their project, MAD Architects strive to return to a human scale, to create a facility that responds to the newest developments in transportation technology, while creating spaces that are comfortable and easy to navigate for its users.
Cities are the bedrock of civilization. For millennia, they have attracted people with the promise of superior standards of living — from better economic and educational opportunities to easier access to quality public infrastructure such as housing, healthcare, and public transport. Today, however, many cities around the world are finding it challenging to live up to this promise. With urban migration accelerating at a dizzying rate – the United Nations projects that over two-thirds of the world's population will live in cities or urban centers by 2050 – existing resources and services in cities are coming under increasing pressure, rendering them dysfunctional and leading to glaring inequities.
There is no singular way to define or assess liveability; every city has a unique set of characteristics, from its history, culture, geography, and demographics, to how it is governed and what urban issues plague it. Therefore, improving liveability requires concerted efforts from multiple stakeholders including people, governments, and experts, to identify critical problem areas and opportunities, and devise contextual solutions. The TV show Tale of Two Cities, where Indian architect and urbanist Dikshu C. Kukreja sits down with global leaders, brings out great insights into what some major cities in the world are doing to create more liveable environments for their inhabitants. Here we present five examples: from Bogotá, Kolkata, Hannover, Tirana, and Washington, D.C.
Last summer, Spain promoted cleaner transportation by offering free seasonal tickets for suburban and regional trains, which translated into roughly 48 million journeys per month. The initiative hoped to help citizens reduce fuel consumption and reduce the cost of living during the economic uncertainties and rising energy prices. In the summer of 2022, a 30% discount for municipal public transport was announced, with local governments in places like Catalonia topping up to a 60% discount. The program ran between the 1st of September and the 31st of December of last year.
