Aldo van Eyck and Lina Bo Bardi were two subversive figures. Their visions of collectivity and playfulness—though applied to very different kinds of structures—shared a common ground: an idea of architecture that goes beyond design. For both, architecture was a living space, animated by appropriation, movement, and exchange. From Dutch playgrounds to thw São Paulo Museum of Art, their ideals intertwined, reinforcing the notion of an architecture where anyone could become a child again.
21st Europe, a Copenhagen-based think tank founded by former SPACE10 creative director Kaave Pour, has introduced its second major blueprint, Continent of Play. Developed in collaboration with design and architecture studio Spacon, the proposal reimagines playgrounds as vital civic infrastructure, positioning them alongside museums, transport hubs, and energy grids as defining spaces for Europe's future.
What if the best kind of play isn't the safest? For decades, cities have built playgrounds to be clean, colorful, and easy to supervise. Yet these spaces—designed more for adult peace of mind than for children's curiosity—often strip away what makes play truly transformative: risk, unpredictability, and self-direction. Rising safety standards, shrinking public space, and the commercialization of play equipment have only further narrowed the possibilities for children's independent exploration. From a junkyard in 1940s Copenhagen to the concrete landscapes of postwar Amsterdam, a handful of architects, planners, and activists have challenged the idea that play must be neat and controlled. Their unconventional playgrounds—made of loose parts, raw materials, and abstract forms—gave children the freedom to build, demolish, explore, and get dirty.
Kindergarten architecture has long stood apart as a realm where design and imagination converge. Unlike most building typologies, these spaces are conceived not only to shelter and function but to shape the earliest experiences of curiosity, play, and social interaction. Throughout history, the design of kindergartens has evolved alongside pedagogical shifts, moving from modest, utilitarian beginnings to highly intentional environments that stimulate both learning and wonder. In this context, architecture becomes more than a backdrop — it becomes a silent educator, capable of nurturing emotional, cognitive, and physical development.
Play extends beyond its recreational dimension, unfolding as a social act that encourages children to learn, interact, be creative, and engage with their spatial context. As Johan Huizinga notes in Homo Ludens, it is a fundamental element of culture, where kids form bonds and explore ways of coexisting. When the architecture of play spaces excludes certain bodies or modes of participation, the collective experience becomes fragmented and loses part of its meaning. Designing with inclusion in mind, therefore, means recognizing that the actual value of play lies in its potential to be shared by everyone.

"No, I don't want to go to that playground. It is boring!" This may sound like something no child would ever utter. But children do have strong opinions on what playgrounds they like, from quite early on. The reason why not only parents and caregivers but also city planners and architects should listen and adjust is more critical than ever.
Urban playgrounds are evolving from simple swing sets and slides into dynamic, multi-faceted urban landscapes. These new designs are more than just places to play; they are thoughtfully integrated spaces that address urban challenges, promote community, and inspire creativity. A key trend is the intentional use of color and pattern. Designers are utilizing vibrant color zones to segment different functional areas, creating a visually dynamic experience that contrasts with natural surroundings. This approach can also be used to establish a cohesive urban identity, with thoughtful color palettes that complement the existing cityscape.
Playgrounds are spatial instruments through which society projects its expectations on childhood, testing the boundaries between control and autonomy, exposure and protection. They regulate how children relate to space, to others, and their bodies — encoding, often invisibly, social norms, fears, and aspirations. In this sense, playgrounds are not peripheral spaces of leisure; they are political constructs shaped by specific ideologies about what childhood is and how it should unfold. Since 1989, the right to play has been formally recognised in the United Nations Convention on the Rights of the Child, affirming that play is a fundamental part of human development. To design a playground is not only to draw lines on a plan or to install equipment in a park; it is to define the conditions under which play is permitted, imagined, or constrained.
When we think about cities and urban life, we often focus on infrastructure, culture, commerce, nightlife, and density. In metropolises where there seems to be an endless array of activities—especially for adults—play rarely enters the conversation. Yet, the act of playing should be considered a vital part of urban life. Play directly influences how we shape our future cities—starting with how children engage with their environments. The experience of play, and more specifically, the design and presence of playgrounds, leaves lasting impressions on how young people grow up in cities. These spaces form a child's first, physical connection to the urban landscape. In this way, play deserves far more attention in conversations around urban wellness, livability, and the design of public space.
From forest-inspired offices in Sweden to jungle-nest clubhouses in Tulum, mixed-use architecture continues to evolve as a tool for integrated living. As cities grow and our expectations of public, private, and commercial space shift, designers are increasingly rethinking how different functions including work, play, rest, learning, can coexist in a single architectural language. These projects suggest that buildings and projects no longer need to silo activities, but rather choreograph them to reflect the rhythms of everyday life.
This collection, submitted by the ArchDaily community, presents a global spectrum of approaches to mixed-use design, from large-scale masterplans to conceptual theses. What ties them together is a commitment to spatial overlap, ecological sensitivity, and reimagined programs that prioritize user experience. Whether it's a student dormitory in Tehran, a public plaza in Cairo, or a community hub in Texas, each project embraces complexity to create spaces that are alive with interaction, transformation, and meaning.
Marking World Play Day, June 11, the Play Pavilion, designed by British architect Peter Cook in collaboration with the LEGO Group, has just opened. The Pavilion is located next to Serpentine South in Kensington Gardens, London. Developed with Pablo Wheldon and Cong Ding, the Pavilion is a collaboration between Serpentine, the LEGO Group, The Royal Parks, and CONSUL. The project builds on Serpentine's broader efforts to connect architecture, design, and public engagement through temporary installations in the park.
In the productivity-driven dynamics of contemporary cities, playful interventions in public spaces offer an innovative way to reclaim urban environments. These interventions encourage new ways of thinking and acting, temporarily breaking the monotony of everyday life and redefining the concept of play. Once confined to childhood and separate from daily activities, play has begun to intertwine with routine paths, becoming an integral part of urban life even outside traditional leisure times. In this way, reintroducing the swing—the most iconic children's toy—becomes particularly significant. As a symbol of childhood, pleasure, and joy, the swing contrasts sharply with the rigid appropriations of most public spaces, inviting a more relaxed and playful engagement with the urban environment. On June 11th, the UN International Day of Play reminds us of the benefits of incorporating diverse activities into urban spaces, for both children and adults, fostering community, creativity, and well-being.
On the first Monday of October, World Architecture Day offers an opportunity to reflect on the role that architecture plays in shaping our world and our communities. Established by the International Union of Architects (UIA) in 1986, this day was designated as a basis for the ongoing discussions on innovations in architectural practice, new approaches to the ever-changing role of architects and designers, and the varied responses to emerging concerns.
As in previous editions, UIA sets a central yearly theme to guide these conversations. This year, the theme of World Architecture Day 2024, "Empowering the Next Generation to Participate in Urban Design," opens up multiple interpretations, contemplating the impact of urban design on the next generation, as well as highlighting the impact and contributions of young architects in shaping the cities of tomorrow. This year's event aims to address crucial challenges faced by the urban environments and their impact on the next generations. The focus is on creating cities that are not only greener and more environmentally friendly but also inclusive, catering to the diverse needs of various groups in society.
Ephemeral architectures, characterized by their temporary and flexible nature, have emerged as powerful tools for revitalizing urban spaces and fostering architectural creativity. These transient installations transform public areas, engaging communities, and prompting reflections on the potential futures of our cities. By temporarily transforming environments, ephemeral architectures encourage both architects and the public to reimagine the possibilities of urban living. This dynamic interplay, between the temporary and the permanent, challenges traditional architectural practices and opens up new avenues for sustainable and inclusive urban development.
Cities constantly undergo infinite changes, leaving many spaces within the urban fabric forgotten and unused. Historic buildings are refurbished, and adaptive reuse explores new possibilities, but what happens with public spaces? Small interventions using simple resources and innovative solutions are the perfect way to bring these neglected alleys, plazas, and highways back to life and reincorporate them into the city.
The idea of a community or public playground is about creating an accessible recreational space for all. However, in many cases, initiating a playground project might fail due to insufficient funds or regulations/restrictions. The first challenge is largely to set the project in motion and, most importantly, get the community’s positive reception and, if possible, its involvement, thus ensuring the project's success and sustainability.
The ArchDaily projects library is managed by our curators who constantly seek to populate our stream with the most interesting global works, showcasing evolving focuses and criteria. While we usually share our reader’s top 100 favorites, this year, we also decided to initiate our editor’s picks on the ArchDaily Instagram account, where our curators highlight some projects that include interesting themes and unique traits.
