Who has the right to the city? Henri Lefebvre's writings question the structures that control urban space and, instead, put the citizens at the center of decision-making. His ideas have influenced the way architecture and urban design are practiced, bringing about community participation and co-design. These have been some of the most prominent themes at Utopian Hours 2026, the festival of city-making, the first part of which was held in the Dutch city of Rotterdam to mark its tenth anniversary edition.
What does optimism feel like in cities that can no longer rely on perfection as their ultimate ambition? Across the world, urban environments bear the weight of overlapping pressures: climate volatility, spatial inequality, political fragmentation, public distrust, and chronic infrastructural disinvestment. These realities render the idea of an ideal city increasingly detached from lived experience. Yet the hope for building better systems persists. While utopian visions may seem like an escape from the growing complexities of the modern world, the greater challenge for contemporary city-making is to confront those complexities rather than avoid them.
Through his unbuilt projects, built works, and research, Amancio Williams's ideas emerge as the result of a deep understanding of the most advanced trends of his time reflecting on architectural design, urbanism and city planning. By exploring various themes, concepts, and even materials, he aims to create a personal universe that interprets the present as something future-oriented, both international and distinctly Argentine. His proposal "La ciudad que necesita la humanidad" presents linear and layered buildings raised 30 meters above ground, incorporating everything from office spaces to roads and magnetic trains on different levels of a single structure. The Amancio Williams archive at the Canadian Centre for Architecture in Montreal documents Williams' career as an architect and designer from the 1940s to the late 1980s. The fonds documents his work for over 80 architectural, urban planning and design projects, as well as the administration of his architecture practice and his professional activities. Including drawings and sketches, presentation models, photographic materials, such as photographs of models, finished project (when realized), reference images, photographic reproduction of plans, and site photographs, the archive is available to consult offering more details.

The emergence of the Digital Twin phenomenon has heralded a great change in terms of urban planning. It essentially presents the city as dynamic, in virtual form. Ensuring every element from the historic fabric, new construction, and public transit is accounted for in one three-dimensional model. Not only does it present key elements in terms of the landscape, but it also encompasses often overlooked conditions such as the presence of light throughout the day, shadows, and the presence of vegetation and trees. All of which contribute to a better preliminary process of site analysis.
Sou Fujimoto Architects has unveiled its design for the top part of the tallest skyscraper in Japan“Torch Tower” in Tokyo, collaborating mainly with Mitsubishi Jisho Sekkei, Inc. Standing tall at 390m, the highrise building planned to be ready by 2028, takes on a large plaza at around 300m, generating a space for people.
More than 55% of the world’s population lives in cities, with that number only expected to increase in the coming decades. Despite the rising population in urban areas, local governments continue to raise flags about inadequate infrastructure and the declining quality of life that cities are facing. Perhaps the large scale problems that we typically categorize as urban innovation, inclusion, and infrastructure, can be solved if we get to the root of the smaller troubles, that we may not even know existed. It’s time to take urban issues off the back burner and improve cities not just for today, but for the long term future.

Sidewalk Labs has unveiled Delve, a new generative design tool that aims to help developers, architects and urban designers identify better neighborhood design options. It uses machine learning to reveal optimal design options from a series of core components, including buildings, open spaces, amenities, streets, and energy infrastructure. By applying machine learning, it explores millions of design possibilities for a given project while measuring the impact of design choices.

By 2025, Frost and Sullivan, a market research company, has predicted that there will be at least 26 fully-fledged major smart cities around the world. While some still think that as our cities get more intelligent, they will resemble sci-fi futuristic movies, the reality is that the quality of life in these cities will drastically improve. Cities are set to become more efficient with better services. Nevertheless, before reaching these ideals, let us go back on the process itself, and evaluate the challenges that we might face.
Because the concept of smart cities is still very new, with rare finalized and implemented projects, the topic is still unclear. Although big titles and strategies are well defined, the on-ground application is still uncertain, giving us the opportunity to question its planning process. In fact, how can we go wrong when designing smart cities? What key element are we failing to address in the planning phase?
Design and the City is a podcast by reSITE, raising questions and proposing solutions for the city of the future. In the second episode, Chris Precht from Studio Precht talks about being part of a new generation of architects, concerned with the environment, climate change, and sustainability, rather than with theories or concepts.
City of the Future is a bi-weekly podcast from Sidewalk Labs that explores ideas and innovations that will transform cities.
In the final episode of season 2, hosts Eric Jaffe and Vanessa Quirk discuss the past, present, and future of responsive architecture with Sidewalk Labs’ director of public realm Jesse Shapins, engineer and microclimate expert Goncalo Pedro, Bubbletecture author Sharon Francis, and renowned architect Liz Diller of Diller Scofidio + Renfro.
Up until now, space architecture has been mainly focused on engineering, centered on projects like orbital space stations or Martian exploration convoys, commissioned by world space agencies such as ESA (Europe) or NASA (USA). But in recent years, an increasingly broader spectrum of professionals (e.g. architects, sociologists) as well as entrepreneurs and investors (not all well intentioned) have joined the challenge of designing extraterrestrial built environments, the new space race of the 21st century.
The fast development of technology, the increase of world population and the climate change crisis create the perfect setting to think about life outside of our planet, and as these trends continue to evolve and converge, new opportunities to explore options beyond our traditional limits appear (NEOM), as well as new organizations which support this research (like SATC, SICSA). Even though no one is currently on Mars, many ongoing projects and simulations (MARS-ONE, Mars City Science) are already exploring how we will design, build and inhabit the new realms of humanity in outer space.

In the fourth episode from season 2, hosts Eric Jaffe and Vanessa Quirk discuss the future of electrification with Gretchen Bakke, author of The Grid: The Fraying Wires Between Americans and Our Energy Future, and Sidewalk Labs’ director of sustainability Charlotte Matthews.

In the third episode from season 2, hosts Eric Jaffe and Vanessa Quirk discuss the future of mobility in cities and share ideas that would make it way easier to get around without owning a car. In the podcast, author Horace Dediu talks about micro-mobility; TriMet's Bibiana McHugh tells the story behind GTFS and the OpenTrip Planner; MaaS Global CEO Sampo Hietanen explains the concept of Mobility as a Service (MaaS); and Sidewalk Labs' Corinna Li explains what Mobility on Demand could be like in the city of the future.

Dutch architectural practice UNStudio have created a new urban vision for the City of the Future, a Central Innovation District (CID) test site in The Hague. Dubbed the "Socio-Technical City", the design covers a 1 square km area in the center of the city. The proposal aims to transform the site into a green, self-sufficient district of housing, offices, urban mobility and public spaces over the existing train track infrastructure.

Steel and concrete facades have dominated contemporary cityscapes for generations, but as pressures from climate change pose new challenges for design and construction industries, some firms are turning to mass timber as the construction material of the future. But could it be used for structures as complex as skyscrapers?
