More than half of the world's population resides in urban areas, with over 4 billion people depending on cities as their main environment. According to the United Nations’ latest report on populations in cities, this number is expected to continue to increase over the next 50 years, prompting cities worldwide to strive to find better ways to accommodate their growing population while transitioning to more sustainable urban practices. To highlight this responsibility, the United Nations has declared July 11th the World Population Day.
Under this year’s theme, “To Leave No One Behind, Count Everyone,” the UN aims to also draw attention to the importance of data collection for reflecting societal diversity. The growth of world cities is part of this equation as an important measure for understanding global population trends. The following list presents the top 20 cities worldwide in 2024, ranked by the population size of their metropolitan areas. Comparing the results to the previous editions, the only cities to reduce their size are the two cities from Japan, Tokyo and Osaka. The highest growth rates can be observed in African mega-cities, Kinshasa and Lagos, while China continues to be the most present country in the list, with 5 metropolises present in the top 20: Shanghai, Beijing, Chongqing, Tianjin, and Guangzhou.
The Royal Institute of British Architects (RIBA) has unveiled the 26 winners of the 2024 RIBA National Awards for Architecture, recognizing the finest examples of UK architecture and showcasing the country’s design and social trends. Established in 1996, the awards highlight outstanding architectural projects across the UK, from Northern Ireland and Scotland to the south of England. This year’s award celebrates projects that feature “inspiring examples of existing buildings and structures that have been given a new lease of life.” Recognized for intelligent design and collaboration with clients and local communities, the award winners also showcase innovative construction techniques and thoughtful material selections.
Increasing urbanization, excessive waste production, excessive consumption of material goods, and exploitation of natural resources. There are many factors that contribute to the environmental impact of humans on Planet Earth. Scarcity of raw materials and the use of non-renewable resources is already the reality of some locations, and nature can no longer reclaim renewables at the same pace as it is exploited. The impact of human activities is so remarkable that scientists have pointed out that we are living in the new geological age of the Anthropocene (the Greek word for “the recent age of man”). The construction industry in particular is a major resource consumer and waste generator. In the European Union, the construction and use of buildings represents about 50% of all resource extraction and energy consumption, and about one third of all water consumption. [1] In 2014, 52% of all waste was attributed to the construction sector. [2].
However, despite their enclosed design appearing to be an obstacle for new uses, recent decades have seen initiatives that embrace and repurpose these structures. These projects integrate silos into the urban environment, emphasizing their significance as part of the local collective memory.
The Santiago Bernabéu Stadium is now recognized as a symbol of Madrid, Spain. Home to the Real Madrid football team, the stadium built in 1947 occupies a key position in the city, adjacent to a major transit artery. The stadium went through several refurbishments since its inauguration, most aimed at increasing the seating capacity. A major modernization process began in 2012, following an international competition. The winning design team is L35 Architects, in collaboration with GMP and Ribas & Ribas. The refurbishment project aimed to redefine the building’s relationship with the surrounding urban spaces, to improve accessibility, and to integrate more activities, from sporting to leisure, commercial, and socio-cultural functions.

The University of Cambridge, in collaboration with BDP, has just unveiled plans to restore and rejuvenate the Grade II* listed History Faculty Building designed by James Stirling. This structure, home to the Seeley Library, is one of the renowned “Red Trilogy” buildings from the 1960s. Initially intended to showcase the significant library and “the act of reading,” the project is internationally celebrated as a landmark from the post-war architecture era. The revitalization project aims to enhance learning and working environments at the University’s Sidgwick site.
Over the years, the nocturnal landscape of cities has witnessed a significant transformation, marked by the emergence of more than 80-night mayors globally, a trend that has been on the rise since the early 2000s. Andreina Seijas, currently working as an Associate at Gehl, has analyzed these shifting dynamics of night-time governance in her research and during her doctoral studies at Harvard GSD. Seijas speaks in the interview about this development, challenges, and opportunities with night mayors, global differences, and the role of climate change. Seijas' upbringing in Caracas, Venezuela, where safety concerns dictated strict curfews, ignited her passion for creating safer, more inclusive urban environments, particularly for the youth. Her quest for a better future for the urban night explores the potential for cities to become safer, more inclusive, and more productive by creating spaces for work and leisure after dark.

The State of Qatar has unveiled the design of its national pavilion to take shape at Expo Osaka 2025. Designed by Kengo Kuma & Associates in collaboration with Qatar Museums, the pavilion blends traditional craftsmanship from Qatar and Japan while highlighting the two countries’ connection to the sea, which is understood as a hub of resources and a medium for trade and knowledge exchange. The prepared exhibition, on view between April 13 and October 13, 2025, aims to showcase Qatar’s innovations across diverse fields.
Until July 14, 2024, the pavilion ¡Qué faena(r)! ('What a Task!') by Óscar Cruz García and Pablo Paradinas Sastre will be installed at Puerta del Sol in Vigo, one of the two winning temporary pavilions of the third edition of TAC! Urban Architecture Festival. Reflecting on public spaces and the regeneration of urban centers as the main theme of this new edition, the proposal combines tradition and innovation, involving local producers and artisans during the process and simultaneously reusing materials considered waste, such as fishing nets, rusty 'bombos,' recovered wood from bateas, and granite blocks that gain a second life after fulfilling their mission in the sea.
The International Day of Cooperatives, celebrated on the first Saturday of July each year, is an opportunity to raise awareness and celebrate the cooperative movement. Celebrated on this day by the United Nations since 1992, the cooperative movement is a social and economic movement empowering individuals and communities by creating enterprises that are collectively owned and democratically controlled by members. This year's theme is “Cooperatives: Partners for Accelerated Sustainable Development.” Underscoring the critical role cooperatives play in achieving the Sustainable Development Goals, it also emphasizes the unique typology of cooperatives in exploring new ways of living together. With a belief in community growth, cooperatives believe in communal development, prioritizing people and supporting them to improve collective well-being.

The team comprised of David Kohn Architects, noA Architecten, and Asli Çiçek has won the international competition for the redesign of SMAK, the Municipal Museum of Contemporary Art in Ghent, Belgium. The project includes the reconfiguration of the museum grounds and the extension of a cluster of historic buildings in the center of the city. Established in 1999, the Stedelijk Museum voor Actuele Kunst aims to redefine its relationship with the city and to create more appropriate space for the design of its extensive contemporary art collection.
His work – more than 250 buildings in the span of 30 years – was lauded by critics and colleagues, cited for international design awards, and landed the architect on the cover of Time. But today, even practitioners and aficionados might be challenged to name one of Minoru Yamasaki's buildings beyond his two most infamous creations that no longer exist: the Pruitt-Igoe housing project in St. Louis and New York’s World Trade Center towers. Paul Kidder explores this complex architect and his work in a new book, Minoru Yamasaki and the Fragility of Architecture (Routledge).
Kidder, a professor of philosophy at Seattle University, provides a fresh, sobering assessment not only of Yamasaki's architecture but the man himself: his challenges, triumphs, and contradictions, as well as the fragility of architectural achievement. The loss of this architect’s most famous buildings suggests the growing scope of architecture’s fragility, especially today, when real-estate investment often augers against preservation of even late-modern works. Yet, paradoxically, Yamasaki believed that fragility could be a desirable architectural quality—the source of its refinement, beauty, and humanity.
At the beginning of the 20th century, the Olympic games included some unusual medal competitions, including architectural design and town planning. While these are no longer awarded Olympic events, architecture and urban planning continues to continue to have a crucial effect on the development of the global sporting event. Cities that bid to host face an important challenge in adapting their infrastructure to accommodate not only the venues and facilities, but all the support structures needed for a safe and enjoyable edition. Paris is no different. While the city hosted 2 previous editions of the games over a century ago, the challenges of the modern-day Games have proven significant. However, the city’s expansive infrastructures have enabled officials to adjust the measures in an effort to have sustainable development for and after the Games. With less than a month to go until the opening ceremony, explore the measures taken by city officials and the long-lasting effects of hosting an Olympic event.

The introduction of AI generative tools represents one of the most significant technological revolutions in the field of architecture and design. While there is concern about this changing the working landscape for professionals in the field, a significant number of practices are embracing the new technology. Architectural visualizations represent one of the main areas where these changes take effect. However, the array of AI tools accessible to non-specialist users rarely allows for true control over the design process, often offering general interpretations of scripts. This can be helpful during early conceptual design phases but loses its appeal soon after. Gendo, a new browser-based app, aims to change this, offering the possibility to not only generate visualizations in seconds but also to edit and customize them, even introducing real-life products in the design. Until August 3, readers of ArchDaily can register and use the code ARCHDAILY50 to get 50% off any plan.

The Ostrava Concert Hall, designed by Steven Holl Architects, has just broken ground in the Czech Republic. Commemorating the start of construction, the concert hall “promises to be an inspiring venue for both locals and internationals who cherish Ostrava’s rich music heritage.” Designed for the Janacek Philharmonic Orchestra, it creates a dramatic contrast between old and new, aiming to create a cultural landmark.
"A bathroom is a place where everyone is equal—there is no rich or poor, no old or young; everyone is part of humanity." This reflection was shared by Wim Wenders, exponent of New German Cinema and director of the filmPerfect Days (2023) when asked about the striking sets of his most recent work. Wenders selected Tokyo's public restrooms to craft a narrative that deeply explores themes of solitude, simplicity, and the beauty of everyday life.
The story follows Hirayama, a middle-aged man working as a public toilet cleaner in Tokyo. His life is simple and routine, yet filled with small pleasures and moments of reflection. This modest lifestyle contrasts with the technological, colorful, and innovative designs of the public restrooms he cleans every day.
Accurate surveys are essential for an architectural project and subsequent construction to run as smoothly as possible. They provide detailed information on the physical characteristics of a site, existing structures, environmental conditions and possible obstacles, which will serve as prerequisites for the design stage, ensuring that all relevant factors are considered before construction begins. This information is vital for making informed decisions that harmonize with the environment and comply with local zoning regulations, building codes and environmental standards. Traditionally, these surveys have relied on manual measurements with tape measures, basic photographs, and, more recently, expensive laser scanning. All of these are susceptible to human error and can be extremely time-consuming, especially in large or complex areas. Laser scanning, despite being more accurate and comprehensive, involves expensive equipment and specialized technicians, increasing project costs and often extending the time needed to carry out the survey.
Located in Mexico City, the municipality of Iztapalapa has some of the most densely populated areas within the metropole. Serving a population of 1,800,000 people, many of them with lower incomes, the municipality struggles to provide sufficient public spaces and amenities. In an effort to correct this, the administration set out to take underutilized and abandoned plots of land and transform them for public use. Utopia Estrella is one of these initiatives. Located near Mexico City’s largest water treatment plant, the project combines a socially engaging architectural program with a pedagogical approach to the role of water infrastructures in the larger ecosystem. Designed by Cano Vera Arquitectura, the project has been recognized as the Gold Prize Winner of the Holcim Awards 2023 for Latin America. In a video interview for ArchDaily, Juan Carlos Cano of Cano Vera Arquitectura discusses the impact of this project, its goals, and the unique conditions that led to its development.
