Concéntrico Festival 2026 will take place in Logroño, Spain, from June 18 to 23, transforming the city into a large-scale laboratory for architecture, design, and urban experimentation. Over six days, more than twenty interventions will be distributed across squares, vacant plots, streets, bridges, and emblematic spaces throughout the city, bringing together leading studios, researchers, and creators from the international scene, including Chilean architect Smiljan Radić, the raumlabor collective, Matilde Cassani, AAU Anastas, and Sahra Hersi, among others. This edition introduces a shift towards more collective, festive, and performative practices in public space, with a strong emphasis on sonic experiences and projects linked to accessibility, inclusion, and urban transformation. The programme is structured around three thematic axes: Identity and Fiction, Urban Ecologies, and Ephemeral Agents, ranging from architectures that understand public space as ritual or celebration to experimental approaches exploring materials, sound, and processes of reuse.
A long table can sit almost anywhere and still do the same work. It can stretch beneath a market canopy, run along a school dining hall, or occupy the center of a shared living room, and it immediately changes the room's temperature.
That is why the long table is less an object than a spatial instrument. It does not guarantee a connection, and it rarely looks "inclusive" by default. Instead, it sets conditions: a shared edge, a common rhythm of arrival, a field of mutual visibility, or a rule that turns eating into a scene with others. Food studies describe this practice as commensality, the act of eating together and the social order it can create, reinforce, or contest. But what matters here is not a specific dimension or the table's function, but the way a long surface holds difference, conversation, and silence; intimacy and distance; the decision to join and the right to hesitate.
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.
The habit of sitting at the table and sharing a specific moment with other people has been present for centuries in the most diverse cultures. The Greek Symposium, Roman Convivium, Medieval Feasts and Banquets, and Parisian Salons are just a few examples of how this custom was historically built and has been relevant in social and political negotiations, intellectual discussions, and philosophical debates.
Commensality often serves as a ritual for bonding, negotiation, and celebrating important events. In many Spanish-speaking cultures, the stretch of time after the meal when the entire family stays seated and talks is so present that there is a word for it: sobremesa — literally translated as "upon the table" (though in Spanish it more accurately means "dessert" or "after-meal conversation"). But, despite often being associated with sharing a meal, the table can be considered a flexible platform open to many possibilities for appropriation and interaction.
As cities continue to develop, we are seeing ever more well-planned, thoroughly executed, and tightly regulated approaches to shaping urban centres and their surrounding spaces—for better and for worse. As codes, restrictions, and guidelines improve and tighten, urban environments become safer, more balanced, and less prone to surprise. Yet the flip side is that highly managed districts can drift toward over-order and sanitisation, shedding the messy, accretive character that once produced alleyways, residual spaces, and unexpected sequences of movement—conditions often born from ongoing community improvisation in the grey zones of regulation.
In response, a growing number of initiatives around the world are proposing short-term urban installations that test alternate futures for the city. These works aim to provoke dialogue between what the city is and what it could offer its communities through thoughtful, context-specific spatial practices. One notable example is Concéntrico, the international festival in Logroño, Spain, conceived as an urban innovation laboratory. Marking its tenth edition, the festival is about to publish Concéntrico: Urban Innovation Laboratory, a book that surveys a decade of urban design and collective transformation shaped through successive editions of the festival. Its launch is paired with an international tour designed to share a decade of insights on collective transformation and design.
August 12, designated by the United Nations as International Youth Day since 1998, was conceived as an occasion to bring youth issues to the forefront of the international agenda and to celebrate the contributions of young people to today's global society. Each year, the observance focuses on a specific theme. In 2025, it is "Local Youth Actions for the SDGs and Beyond," emphasizing the role of youth in transforming global ambitions into community-driven realities. The aim is to highlight how young people help implement the Sustainable Development Goals (SDGs) within local contexts and bridge the gap between policy and practice. In this spirit, we present three educational programs, in Romania, the United Kingdom, and the United States, that empower youth to deepen their understanding of the built environment and envision a more sustainable, people-friendly urban future.
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.
How do pavilions emerge in architecture? What role do they play in urban spaces? Beyond the multiple interpretations that exist around the world, the pavilion, as an architectural principle and typology, tends toward extroversion, often associated with a centrifugal nature and visual openness toward the horizon, which is linked to its origins as a tent offering shelter from the elements. Pavilions are usually identified as isolated and independent structures that can promote lateral openings in the urban space, panoramic or introspective views, technological reflections, and material experiments that are recognizable from the outside or once inside.
2025 promises to be a landmark in architecture, heralding a vibrant renaissance of creativity and exploration. As societies confront challenges such as climate change, rapid urbanization, and technological evolution, architecture is both a mirror to these dynamics and a compass pointing toward a sustainable and inclusive future. This year's architectural calendar offers abundant opportunities to celebrate the discipline's transformative power — from boundary-pushing festivals to thought-provoking exhibitions that explore pressing cultural and environmental narratives.
From well-established biennials to inaugural gatherings, including the World Architecture Festival 2025, Desert X Al Ula, and the COP Climate Conference, the 2025 calendar highlights themes such as sustainability, heritage, and community. These events underscore architecture's unique ability to shape a better future, addressing global challenges while honoring cultural diversity and design ingenuity.
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.
Biennales, exhibitions, and architecture focused festivals provide a platform for opening debates, conducting research, and driving innovation, but they can also contribute to the incremental changes that shape the image and the character of a city. Through temporary installations and experiments, this type of events have the opportunity to open lines on inquiry into the quality of urban spaces, inviting visitors and residents to slow down, break away from their daily routine and interrogate their local environments. The effects might not be immediate, but by cumulating these impressions and moments of contemplation, architecture and design festivals can have a long-lasting impact on the cities that welcome them.
Staged stories on community and identity, ephemeral architecture showed that in 2022 it doesn't have to be permanent to be powerful. A direct and popped-up public installation can shift from preparation to action, reclaiming and defining what makes a community unique. Highlighting installations to acknowledge linguistic diversity in NYC, a giant table to celebrate culinary in Barcelona, and a large-scale net in Dubai to represent the local culture, among others, these initiatives seek to understand ways in which local and regional expressions can help cities to be more equal and diverse.
Globalization has connected the world boundaryless. While it has also made information more accessible, it has led to homogeneity and identity crisis at melding unique societies and cultural expressions. Cultural differences are undeniable as globalization grows. Hence, as architecture produces common living standards, it can also highlight singularities. Festivals, installations, and pavilions, 2022 was the year to express local memories to be recognized and celebrated, setting Community and identity as central topics in ephemeral architecture throughout the year.
As expressed by 2023 Venice Architecture Biennale curator and architect Leslie Lokko, "after two of the most difficult and divisive years in living memory, architects have a unique opportunity to show the world what we do best: put forward ambitious and creative ideas that help us imagine a more equitable and optimistic future in common."
From Venice's approach to Africa as the lab for the future to Seoul's road to its next 100 years as a megapolis; from Chicago's art-meets-architecture-meets-civic-participation to Sharjah's "beauty of impermanence" in the Global South motto, 2023 will witness a series of architectural events trying to embody those forward ambitious and creative ideas, as explained by Lokko.
