Leisure spaces are often where different generations cross paths. Without formal programs or assigned roles, they allow people to move, pause, and remain together, each engaging space in their own way. In a built environment increasingly shaped by specialization and separation, these shared spatial grounds have become less common, giving leisure-oriented architecture a renewed relevance.
Discussions around public space have repeatedly pointed to the value of openness and flexibility in supporting collective life. As architect Herman Hertzberger has noted, "the more a space can be interpreted in different ways, the more people it can accommodate." Rather than attempting to create interaction, architecture shapes the conditions that make togetherness possible.
This past year marked a period of introspection for architecture. As 2025 unfolded, the discipline, confronted with evolving environmental and social realities, entered a broader turning point in how it understands its role and how users engage with it. Throughout the year, exhibitions shifted focus away from buildings as isolated objects toward a broader understanding of relationships between ecology, equity, everyday life, and collective imaginaries. Across institutions and cities, they operated less as showcases and more as discursive platforms: places where architecture was not only presented, but also imagined, questioned, and collectively redefined.
While exhibitions have long functioned as sites of discourse, politics, and community, this role became more explicit in 2025. As Carlo Ratti noted in an ArchDaily interview during the pre-opening of the Venice Architecture Biennale 2025, exhibitions today can "hybridize the way that people come together," an ambition that echoed across cities and institutions as exhibitions evolved into spaces for debate, experimentation, and collective reflection. Exhibitions are places where architects and designers meet, where conversations unfold openly with the public, and where ideas emerge through spontaneous exchanges among passersby. Exhibitions became spaces where architectural discourse extended beyond professional circles, opening conversations to broader publics through everyday encounters, shared experiences, and informal exchanges.
Specificity has re-emerged as a central language in architectural discourse. In an increasingly globalized field, where projects often follow familiar models regardless of context, architects are now turning toward approaches rooted in the particularities of each site. This renewed attention to context reflects broader social, climatic, and political pressures: cities are facing extreme heat, ecological challenges, shifting demographics, and new forms of collective life that demand responses grounded in their immediate conditions.
Situated architecture describes this shift. It refers to design approaches in which form, program, and materiality emerge from the specific environment that produces them: its microclimates, cultural structures, and everyday rituals. Rather than beginning with universal templates, these practices start with observation, prototyping, and direct engagement with local dynamics. This logic is visible in the climatic and material experiments of TAKK in Spain, such as Portable Garden and 10k House, which operate as lightweight prototypes tuned to thermal and ecological gradients; in Studio Ossidiana's Art Pavilion M, shaped by layered soils and ecological cycles in the Netherlands; in Izaskun Chinchilla's reinterpretations of vernacular objects and her later experiments with 100 Sillas and 3 Salones Urbanos; in the narrative-driven domestic spaces explored by Common Accounts; and in Raumlabor's urban interventions that respond directly to the specificities of post-industrial Berlin.
Every June, the Spanish city of Logroño transforms into a space of architectural dialogue, opening its streets, plazas, riverbanks, and traffic islands to temporary structures that redefine how cities are inhabited. For ten editions, Concéntrico has worked not as a specialized fair or an architecture biennale, but as a portable museum — a curatorial gesture that brings a dispersed collection of contemporary architecture into public space. Set in a city suspended between arid plains and distant mountains, far from the circuits of capital cities and cultural institutions, Concéntrico presents itself as a temporary promise. It's a reminder that even cities that are often overlooked can host architecture that is current, diverse, and speculative. In this sense, the festival is less about celebration and more about activation.
But beyond its curatorial logic, Concéntrico operates as a political structure. In the ancient sense of polis, it invites citizens, architects, and institutions to reassess what public space can be. The interventions offer speculative proposals for urban life that reveal what is missing, what is possible, and what should be questioned. A temporary pool over a fountain, a bathhouse in a roundabout, or a shared meal on a major avenue are not just spatial gestures — they are political statements, asking how urban infrastructure might be redirected from control to care, from efficiency to encounter. In that way, the festival becomes not just a reflection of the city, but an instrument for its transformation.
The 11th edition of Concéntrico, the International Festival of Architecture and Design, is currently taking place in Logroño, Spain, from June 19 to 24, 2025. This year's edition broadens the scope of the festival with a multifaceted programme that includes not only temporary installations but also permanent projects, exhibitions, educational initiatives, and traveling events. Through 24 urban interventions, Concéntrico 2025 explores themes such as material reuse and circular design, food as a collective practice, the recovery of water-related spaces, the activation of urban voids, and interspecies connections in the urban context, while emphasizing the need to imagine new ways of inhabiting the city, placing care, sustainability, empathy, and active listening at the core of public architecture.
Public space has long been central to architectural thought, often framed in terms of planning, infrastructure, and regulation. From Haussmann's Paris to contemporary masterplans, architects have worked to define and formalise collective life through spatial tools. Yet, outside of these frameworks, artists have continuously offered alternative ways of understanding and inhabiting public space—ways that rely not on construction or permanence, but on presence, perception, and participation. Through actions, objects, or atmospheres, artists engage the city as a site of friction and imagination. These gestures challenge architectural conventions and invite artists to reconsider public space not as a solved form, but as a contingent and open process.
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.
How can architecture professionals transform the atmosphere of a structure? What kinds of interventions can go beyond adaptive reuse to modify spatial perception? As architectural structures are repurposed over time, new uses and needs emerge between spaces and their users. While the structures of old buildings keep the memory of communities alive, the introduction of new life through greenhouses, housing, commerce, offices, or cultural centers brings about new atmospheres where light, ventilation, the integration of nature, and other elements reshape interior experiences.
A previous exploration of cultural landmarks in the Middle East designed by international architects highlighted recurring themes such as architecture as an extension of the landscape, climate-responsive design, and abstraction of traditional forms. These projects often introduced high-tech environmental solutions, used monumental forms to reinterpret local identity, or positioned themselves as landmarks within the broader urban or desert landscape. While these approaches have defined many of the region's most recognizable cultural institutions, they represent just one side of the architectural discourse. An equally significant yet distinct trajectory emerges from local architects, who work within existing structures, historical contexts, and lived environments to create institutions that feel deeply embedded in their surroundings. This approach prioritizes continuity, transformation, and accessibility, ensuring that architecture remains an evolving part of the cultural fabric rather than a self-contained object.
As Athens hosts The Architect Show (TAS) 2024, the event brings together global and local voices to highlight the latest innovations in architecture and design. Against this backdrop, the city's evolving urban narrative is exemplified by The Ellinikon, Europe's largest urban regeneration project. Encompassing 6.2 million square meters, this €8 billion development has already attracted globally renowned architects such as Bjarke Ingels Group (BIG), Kengo Kuma, Foster + Partners, and Aedas. Together, they are shaping the smart city that integrates sustainability, connectivity, and community-focused design into the heart of Athens.
Recognized for completing 36 distinct yet cohesive public projects across Mexico in just 36 months, Colectivo C733 showcases the impact of collaborative design on public spaces and communities. The 36 projects were part of a national effort to revitalize vulnerable urban and rural areas in Mexico, earning them the 2024 Obel Award focused on the theme of "Architectures With". The team behind the designs, Colectivo C733, is a collaborative group formed by the joint offices of architects Gabriela Carrillo (Taller Gabriela Carrillo), Carlos Facio, and José Amozurrutia (TO), along with Eric Valdez (Labg), and Israel Espin. In a recent conversation with ArchDaily's Editor-in-Chief, Christele Harrouk, the collective discussed their approach to public architecture, the process of integrating diverse voices, and remaining flexible to the challenges of local conditions.
In celebration of Urban October, a month dedicated to recognizing the significance of innovative urban spaces, this curated selection presents 8 conceptual projects that demonstrate the transformative potential of public spaces. These projects, submitted by the ArchDaily community, showcase the myriad ways public spaces can enhance cultural identity, community interaction, and environmental quality. Conceptual projects and competition entries serve as a platform for architectural experimentation, challenging the norms and sparking discussions about the future of urban landscapes. From rural settings to layered historical squares or small-scale urban interventions, the designs engage with their contexts, aiming to improve the experience of residents and visitors, highlight the histories of the space, and ensure accessibility for all.
Each month, ArchDaily's editors select a collection of conceptual projects centered around a theme or program, submitted to ArchDaily.

Submissions are open to everybody. If you wish to contribute, send in your work by following the instructions here.
Urban infrastructure intended for city connectivity disrupts urban patterns and often leaves behind a series of spaces without a properly defined use. Fortunately, the notion of space beneath infrastructure is being redefined, as architects are generating public spaces nestled under flyovers, bridges, and other urban structures.
Formerly neglected spaces, overlooked or dismissed as mere leftovers of urban planning, are now transformed into dynamic environments for community engagement and artistic expression. Architects, city planners, and the users themselves are embracing the challenge of reclaiming forgotten or underutilized areas and developing innovative solutions, integrating greenery, art installations, and sustainable elements into the urban fabric.
Architecture and Design Festival Concéntrico celebrates its 10th anniversary from 25 April to 1 May 2024 with an edition that aims to reflect on the impact of the annual festival upon the city of Logroño, Spain, as well as to consider how the city continues to evolve. Through installations, exhibitions, lectures, performances, workshops, and activities, Concéntrico proposes a reflection of the urban environment, welcoming architects and designers to intervene and challenge it while opening conversations about pressing matters.
While the official theme of the festival focused on the future of cities, the invited architects and designers took this suggestion further. Several overarching themes and subjects emerged during this year’s event, from the incorporation of concepts of time, an unusual element to be tacked through temporary installations, to the desire to engage more honestly with a wider public, to listen to their needs and create platforms where diverse perspectives can take center stage.
From April 25 to May 1, 2024, Logroño hosts the tenth edition of Concéntrico, a celebration of urban innovation and transformation. This year, the festival explores the future of cities, incorporating new formats, engaging diverse audiences, and tackling urban challenges through the lens of time as a catalyst for change in design. Featuring 20 interventions and activities involving over 100 professionals from 17 countries, the program encompasses processes such as renaturalizing public spaces, reimagining urban structures, and integrating recycled materials from previous editions.
Additionally, collaborations with educational centers ensure a lasting impact beyond the festival, fostering new collective practices in public spaces. Special projects such as "The street in 10 years" or initiatives involving students and pupils from local schools and educational centers further enrich the festival's engagement with communities across Spain.
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.

Architecture practices usually start their design process with a client, who provides a program and a site. Alejandro Haiek, founder of The Public Machinery, approaches things differently. The Public Machinery describes itself as a network of architects and designers working collectively, actively observing, imagining, and proposing public urban interventions themselves. Their proposals are at the intersection of art, architecture, and engineering and weave community engagement, ecology, and new technologies into innovative forms of social infrastructure. They secure funding through research and public grants, enabling them to create public spaces that defy expectations in both their design process and in the form their projects take.
