Ephemeral Architecture: The Latest Architecture and News

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.

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.
