Every city carries, woven into its fabric, fissures that resist capture: ruins, vacant lots, leftover infrastructures, and gaps that persist at the margins of the official narrative. These are places that slip through the logics of planning, emerging as unexpected counter-scenes within a territory that seeks to present itself as coherent.
In the rush to organize and predict, we rarely pause to notice what emerges from such unforeseen conditions. Yet it is precisely in them that new forms of urban life begin to take shape. Free from pragmatic control or predetermined codes of conduct, these spaces reveal another layer of the city — one that, in its continual state of latency, opens room for new modes of appropriation.
Domestic workers in Hong Kong and Singapore are the city's quiet infrastructure. In Hong Kong alone, there are a total of roughly 300,000 domestic workers, serving a portion of the approximate 2.7 million households. Their care labor sustains dual-income family routines: childcare, eldercare, cooking, cleaning, and the everyday logistics that make professional life possible. Yet the people who hold this balance together remain largely invisible in policy—and, crucially, in space.
On Sundays in Hong Kong's financial district, that invisibility becomes visible. Elevated walkways and podium forecourts—underused on weekends—turn into ad-hoc commons. With cardboard mats, small tents, towels, food and water, and a music speaker or two, domestic workers assemble places to sit, rest, and socialize. These improvised rooms in the city are often their only chance to exercise spatial agency—something they rarely have in the homes they maintain or in formal public infrastructure. In the absence of sanctioned, serviced places for rest, quieter bridges and passages become practical stand-ins.
Urban policymakers and developers increasingly brand projects as temporary, piloting pop-up parks, art installations, and interim structures across global cities. Initiatives are often framed as experimental interventions that activate vacant sites. In practice, however, they frequently serve as provisional strategies to manage underutilized land until more profitable forms of development materialize. The temporary label functions as urban camouflage, obscuring permanent agendas behind provisional rhetoric.
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.
Buildings are physical, static, and permanent. To imagine them otherwise often requires some creative thinking. The industry has operated with this strong association between structures and permanence, unknowingly constraining perspectives on building life cycles. Innovations in building materials have opened up avenues for cirular design that challenge the long-held notion that buildings must endure indefinitely. Emerging approaches promote architecture that ebbs and flows with nature.
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.
What if we imagined buildings as living systems, designed for assembly and disassembly with minimal impact? A form of open, modular, and adaptable architecture designed to evolve with its surroundings, responding to seasonal changes and on-demand needs instead of remaining static. At first glance, the idea seems paradoxical, as many buildings were constructed to last, designed to endure, resist the effects of time, and avoid demolition. Because of this, reversing or undoing could be seen as a setback. But what if that way of thinking no longer fits every scenario?

Every year, the Naomi Milgrom Foundation commissions an architect to design a temporary pavilion for the Queen Victoria Gardens, in the center of Melbourne's Southbank Arts Precinct. The pavilions are then transferred to the state of Victoria. The tenth edition of the MPavilion was designed by Pritzker Prize Laureate Tadao Ando as his first and only built work in Australia and the southern hemisphere. The pavilion opened on November 16, 2023, and its presence was extended until March 2025, hosting a wide-ranging program of cultural events over two summer seasons. After facing demolition, given the temporary nature of the initiative, a community-led program, "Preserve the Pavilion", was launched in hopes of preserving the building. The Naomi Milgrom Foundation has recently announced that the pavilion will remain in Queen Victoria Gardens until 2030, following a decision by the City of Melbourne.

The TAC! Urban Architecture Festival is held annually in Spain with the aim of bringing contemporary architecture closer to the public through installations in various cities, including Granada, San Sebastián, Valencia, Vigo, and San Fernando. Organized by the Ministry of Housing and Urban Agenda in collaboration with Fundación Arquia, the festival seeks to promote experimentation in architecture by constructing temporary pavilions for cultural events and gatherings. The 2025 edition of the festival will take place in two locations: Casa Mediterráneo in Alicante and Plaza Stagno in Las Palmas de Gran Canaria. The pavilions are selected each year through an open call for young architects up to 45 years old. This year's winners have already been announced: the ESPARTAL project by ELE Arkitektura, GA Estudio, Florencia Galecio, and Juan Gubbins; and DE ROCA MADRE by Alejandro Carrasco Hidalgo, Eduardo Cilleruelo Terán, Alberto Martínez García, and Andrea Molina Cuadro.
At the end of each edition of the Architecture Biennale, far from the public eye, tons of exhibition materials are transported across Venice in handcarts and boats. Only a small portion of these materials is reused. The main obstacles are the limited storage space in Venice and the high logistical costs—recurring challenges for circular architecture. As a result, most of the waste ends up in landfills or nearby recycling centers. But this scenario is beginning to change. In response to growing environmental concerns, architects are developing strategies to make reuse more viable. These efforts go beyond architectural and construction decisions—they also involve logistics and international trade.
In recent years, architecture has increasingly embraced adaptability, flexibility, and responsiveness as core design principles. This evolution reflects a shift from traditional notions of static, permanent structures to dynamic environments that can adjust to changing needs and conditions. Central to this transformation is the concept of "soft architecture", which leverages pliable materials and innovative systems to create spaces that are functional, sustainable, and user-centric. Soft architecture takes shape through membranes that breathe, façades that move, structures that inflate or fold, and surfaces that bend rather than break. It involves designing for transformation — not only in how a building performs environmentally, but also in how it can accommodate shifting functions, user interactions, or temporary occupations. This approach to building challenges traditional notions of durability and control, proposing instead a more responsive and open-ended architecture. It reflects a growing awareness that buildings, like the societies they serve, must be able to evolve.
Tucked within the leafy confines of the Giardini della Biennale in Venice stands a structure modest in scale yet immense in quiet conviction: the Finland Pavilion, designed by Alvar and Elissa Aalto for the 1956 Venice Biennale. Unlike the monumental pavilions that surround it, Aalto's structure was conceived not as a permanent structure, but as a temporary exhibition space for a single exhibition season. And yet, nearly seventy years on, it remains—weathered, resilient, and quietly luminous.
Bangladeshi architect and educator Marina Tabassum and her firm, Marina Tabassum Architects, have been selected to design the 2025 SerpentinePavilion. Titled "A Capsule in Time," the proposal takes inspiration from the ephemeral nature of architecture in the Bengal Delta, incorporating a semi-transparent structure intended to evoke a sense of community and connection. The Pavilion will open to the public on June 6th, until 26 October 2025, with a press preview two days before the opening. Tabassum's pavilion will mark the 25th year since the Serpentine's first commission of Zaha Hadid's inaugural structure in Hyde Park in 2000.
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.
The Luxembourg national pavilion, designed by Luxembourg-based office STDM architectes urbanistes in collaboration with Japanese office MIKAN, with the concept of "Doki-Doki –The Luxembourg Heartbeat," has just opened its doors at the Osaka 2025 World Expo. The pavilion takes its name from the Japanese term for heartbeat, aiming to express joy and enthusiasm while strengthening the connection between the two countries. It also strives to offer visitors a chance to discover the cultural richness of Luxembourg and its multifaceted identity.
The bamboo scaffolding building typology—temporary, agile, and deeply rooted in tradition—particularly, the bamboo shed theatre building technique, is recognized as an item of Intangible Cultural Heritage in Hong Kong. As one walks through the city, especially in busy urban districts, it's nearly impossible not to encounter a bamboo scaffold within a five-minute radius. Bamboo scaffolding is arguably the most iconic construction material in Hong Kong, valued for its abundance, sustainability, flexibility, adaptability, and—most importantly—scalability. These qualities have contributed to its widespread use in temporary construction, from building maintenance and renovations to festival stages and sporting events.
However, this once-ubiquitous feature of the urban landscape may be slowly fading from view. A dwindling pool of skilled, younger workers—combined with evolving construction regulations—has contributed to its decline. On March 17, the Development Bureau announced plans to "drive a wider adoption of metal scaffolds in public building works." In practice, this means the Architectural Services Department (ArchSD) will soon require at least 50% of its capital works projects to utilize metal scaffolding. While not a formal ban, the policy signals what many see as the beginning of a gradual phase-out of bamboo scaffolding in public-sector construction.
The 2025 edition of the Coachella Valley Music & Arts Festival continues its tradition of merging large-scale contemporary art with music, transforming the Empire Polo Field into a dynamic landscape of immersive installations. Curated by Raffi Lehrer of Public Art Company (PAC) in collaboration with Goldenvoice Art Director Paul Clemente, this year's program explores themes of movement, illusion, and impermanence through newly commissioned works and returning artists. Since 2016, Coachella's art program has evolved into a multidisciplinary platform, with most of its production managed in-house and on-site. The 2025 festival runs across two weekends, April 11-13 and April 18-20. This year's edition includes three newly commissioned art installations in addition to the permanent and returning exhibits.
The 2025 edition of Milan Design Week and Salone del Mobile.Milano, spanning April 7th to 13th, brought together a diverse range of temporary installations at the intersection of architecture, design, and material innovation. Spread across historic sites, courtyards, and exhibition venues throughout the city, these site-specific works explored concepts such as sustainability, impermanence, sensory experience, and spatial interaction, in line with the theme of this edition of exploring the deep connections between humanity and design. Architectural studios, designers, and artists collaborated with brands and institutions to create environments that responded to context while proposing new approaches to how spaces are designed, experienced, and constructed. The following selection highlights ten installations presented during the week, reflecting a range of design approaches, materials, and spatial concepts.
