Ephemeral Architecture: The Latest Architecture and News

Daryan Knoblauch's work sits at the intersection of architecture and live cultural production, with a focus on how space is made legible through tension and atmosphere. Rather than treating temporary work as a lesser category of architecture, Knoblauch approaches installations, stages, and event architectures as full disciplinary problems—where enclosure, stability, light, and movement must be resolved with the same seriousness as any building, often under tighter constraints and faster timelines.

Across projects, a consistent thread is the productive tension between high-modern precision and an intentionally raw clarity of assembly. Membranes and lightweight systems are not deployed as surface effects, but as structural and spatial instruments—tuned to wind, load, and occupation, and calibrated to produce a sublimity that is felt as much as it is seen. Here, ephemerality is not simply a duration, but a design condition: temporality makes forces—weather, wear, performance—more visible, and demands an ethic of making that is both exacting and adaptable.

What do lightweight materials bring to public space with an ethical, ecological, and non-extractive design principle? Various textile textures offer a point of entry, being closer to the body than heavy conventional structural materials. Through its flexibility and responsiveness, it enables a form of soft enclosure rather than a fixed boundary in architectural space. Responding to minimal environmental stimuli, the fabric brings continuous movements into space. When layered or assembled, it produces gradations of density, depth, and enclosure, while recent innovative fabrication technologies extend the possibilities of its form and structural durability.

Semi-transparent materials further mediate the conditions of visual permeability and bodily experience of the space. By transmitting and filtering light, they blur clear separations between interior and exterior, solid and void, creating thresholds that are neither fully open nor fully enclosed, but constantly in negotiation. Reinterpreting structure in urban space through lightweight, translucency, and softness opens up alternative modes of spatial perception and bodily engagement.

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.

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.

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.

The Serbian Pavilion at the 19th Venice Architecture Biennale consists of an immersive installation made of wool. The exhibition, titled Unraveling: New Spaces, was curated by architect Slobodan Jović and designed by an interdisciplinary team composed of Davor Ereš, Jelena Mitrović, Igor Pantić, Sonja Krstić, Ivana Najdanović, and Petar Laušević. The interior space of the Pavilion, located in the Biennale's Giardini, is occupied by an ephemeral installation that follows the principles of circular design, effectively producing no waste. The installation consists of a broad woven wool fabric that gradually unknits according to a guided choreography of algorithmic precision, completely disassembling by the end of the Biennale's exhibition.

Bangladeshi architect and educator Marina Tabassum and her firm, Marina Tabassum Architects, have been selected to design the 2025 Serpentine Pavilion. 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.

Known for its unconventional art installations and striking desert setting, the Burning Man festival has concluded this year with an array of temporary installations spread across the Black Rock Desert in Nevada. The festival's 2024 theme, "Curiouser & Curiouser," inspired by Lewis Carroll's Alice in Wonderland, encouraged participants to embrace wonder and whimsy.

At Burning Man, a tapestry of themes emerges through diverse installations, from reflections on connectivity and isolation to explorations of time and space. Installations like Nebula Shroom Grove and the Temple of Together emphasize community and unity, inviting interaction and participation. Pieces like "I'm Fine" and Tree Circle delve into universal emotions and humanity's connection to the infinite, while works like Matter Out of Time and The End of Time play with perceptions of time and reality.

Every August, the Black Rock Desert in Nevada transforms into a vibrant city for Burning Man, a week-long festival that culminates in the ceremonial burning of a large wooden effigy. Established in 1986, the festival is renowned for its unconventional art installations and striking desert setting. While varied in their expression, the installations follow a central theme of the year. For this edition, the title “Curiouser & Curiouser” takes inspiration from the Mad Hatter from Lewis Carroll’s Alice in Wonderland, prompting participants to engage with wonder and embrace the whimsical and mysterious. This year’s central temple installation is designed by Caroline Ghosn to represent togetherness and mutual respect. Following a Burning Man Tradition, the temple design is selected following an international competition.

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.

Until July 14, 2024, the pavilion ¡Qué faena(r)! ('What a Task!') by Óscar Cruz García and Pablo Paradinas Sastre will be installed at Puerta del Sol in Vigo, one of the two winning temporary pavilions of the third edition of TAC! Urban Architecture Festival. Reflecting on public spaces and the regeneration of urban centers as the main theme of this new edition, the proposal combines tradition and innovation, involving local producers and artisans during the process and simultaneously reusing materials considered waste, such as fishing nets, rusty 'bombos,' recovered wood from bateas, and granite blocks that gain a second life after fulfilling their mission in the sea.

India's urbanscapes are characterized by a negotiation between the formal and the informal; permanence and impermanence. Structured amidst the concrete high-rises and planned neighborhoods, makeshift markets and bazaars form the core of city life. Often composed of sustainable structures, these transient commercial hubs exhibit a form of rudimentary architecture that spreads its roots deep in India's cultural and economic traditions.

The heart of India's informal urbanism lies in its public marketplaces and roadside bazaars that have existed for centuries. These urban zones have a history, believed to have originated from the era of traveling merchants and imperial trade relations. Today, these environments have evolved into dense labyrinths of impermanent shelters made from recycled tin sheets, tarpaulin canopies, and wooden poles. These bazaars organically transform neighborhoods into a choreographed chaos of vendors, goods, and the common public. Weekly markets are usually massive in scale and are set up every few days only to disappear again.

To convey the might and prestige of their empire, the Romans constructed enduring architecture as symbols of their long-lasting reign. Emperors employed grand public works as assertions of their status and reputation. Conversely, Japanese architecture has long embraced ideas of change and renewal, evident in the ritualistic rebuilding of Shinto shrines. A practice, known as shikinen sengu, is observed at Ise Jingu, where the shrine is purposefully dismantled and reconstructed every twenty years. Across the world, philosophies around permanence and impermanence pervaded architectural traditions. Amidst the climate crisis, how do these tenets apply to modern architectural design?

“Self Similar,” a sprawling and immersive land artwork created by Jim Denevan has just debuted in Abu Dhabi, UAE as part of a more extensive city-wide exhibition. Curated by Reem Fadda, Director of Abu Dhabi Culture Programming and Cultural Foundation, along with Alia Zaal Lootah, this city-wide exhibition showcases 35 distinct site-specific artworks by both local and international artists. Scheduled to run until January 30, 2024, the exhibit is a diverse collection aiming to engage audiences.

Throughout the modern era, pavilion architecture has consistently reflected cutting-edge architectural trends. These temporary or semi-permanent structures, often featured in exhibitions, fairs, cultural events, and sports gatherings, provide a platform for exploring new materials and design concepts. Pavilion designs are intended for easy assembly and disassembly and are typically used for short durations, making it crucial to consider reducing environmental impact without sacrificing aesthetics and innovation. In this endeavor, wood emerges as a key ally.
