Architectural Decisions, Planetary Implications: Interview with UIA 2026 Barcelona Curatorial Team

Romullo Baratto — Mon, 29 Jun 2026 07:30:00 +0000

Barcelona is the first city in the history of the UIA World Congress of Architects to host the event twice. The 1996 edition, Present and Futures: Architecture in Cities, arrived at a charged moment, when the post-Olympic city was consolidating an urban model that would become one of the most studied and contested in contemporary urbanism, and when architecture was learning to think through the large metropolis as its primary site of inquiry. Thirty years later, the same city reopens the question under a different condition: one in which the built environment can no longer be understood as a self-contained object, but only through the wider ecological, material, and political systems that sustain it. The theme of the 2026 Congress — Becoming. Architectures for a Planet in Transition — does not abandon the urban concerns of 1996; it reopens them from a planetary scale.

Function Follows Form: Designing Adaptive Buildings That Outlast Their Original Use

Eduardo Souza — Wed, 24 Jun 2026 04:00:00 +0000

With forty-eight psychogeriatric beds and sixty-eight wheelchair-accessible apartments, accommodation for informal caregivers, and space for bedside care, the De Keyzer building opened in Amsterdam in 2011. Its program had been conceived entirely for elderly people requiring assistance, but shortly after completion, the building was sold to an investment fund, and the apartments began to be rented to young families with children.

From Waste to Wall: Sugarcane Bagasse as Low-Carbon Building Material

Agustina Iñiguez — Wed, 17 Jun 2026 07:30:00 +0000

From acoustic and thermal cladding systems to masonry units and textiles made from agricultural waste, experimentation with bio-based materials continues to drive sustainable solutions for the construction industry. Faced with the urgent need to rethink how we conceive of and interact with the materials that shape the built environment, professionals, researchers, and educators are addressing different design scales and project phases, recognizing the importance of reducing carbon emissions and the industry's environmental impact. In partnership with Bagaceira Project, the Sugarcrete® acoustic and thermal panel prototype, developed by the University of East London (UEL), demonstrates how low-carbon design can transform agricultural waste into high-performance building materials.

Arquivo: Deconstruction and Material Reuse for a Circular Architecture

Susanna Moreira — Thu, 09 Apr 2026 04:00:00 +0000

The construction industry today faces an unavoidable paradox: the urgent need for sustainable solutions for the future of cities collides with the exhaustion of the term "sustainability" itself, often reduced to a hollow commercial label. In this scenario, Arquivo – one of the winners of ArchDaily's 2025 Next Practices Award – emerges as a facilitator and mediator between different stakeholders in the construction field through disassembly – or rather, de-construction – and the reuse of building elements. Etymologically, if "construction" derives from the Latin construere (to heap up, assemble), the prefix "de-" imposes a conceptual inversion: it is not about destroying, but about disassembling with intelligence to understand the logic of the parts.

Designing for Obsolescence in an Age of Perpetual Upgrades

Eduardo Souza — Tue, 24 Mar 2026 07:30:00 +0000

In the nineteenth century, entire railway networks became obsolete almost overnight, not due to physical deterioration, but because of changes in the technical standards that supported them. The expansion of railroads across Europe and North America adopted different track gauges (the transverse distance between rails), and as a dominant standard gradually emerged, these infrastructures became incompatible with one another. This required large-scale adaptations, conversions, or even complete reconstruction, in what became known as the "Gauge War."

The Technosphere: ArchDaily’s March Editorial Focus

Romullo Baratto — Wed, 04 Mar 2026 09:00:00 +0000

How heavy is a house? In his 1965 essay A Home Is Not a House, Reyner Banham observed that modern American dwellings were becoming structurally lighter while growing heavier in mechanical services, such as plumbing, wiring, heating, and cooling. The true weight of architecture, he argued, was no longer in walls and roofs, but in the energy-intensive systems that sustained comfort.

Barbara Buser Recognized With the 2026 Jane Drew Prize for Her Work In Circular Construction

Antonia Piñeiro — Tue, 03 Mar 2026 06:30:00 +0000

The AJ and The Architectural Review have named architect Barbara Buser as the winner of the 2026 Jane Drew Prize. The prize, named after English modernist architect and urban designer Jane Drew, is part of the W Awards and the W Programme, which recognise women's contributions to the architectural profession. Swiss-based architect Barbara Buser is known as an innovator in the field of recycling and reuse, and as an expert in circular construction, recognised for pioneering repurposing practices in Switzerland. The award, therefore, recognises not only her contribution to architecture itself, but above all her efforts to reduce the industry's environmental impact through socialisation initiatives. The recognition follows Anne Lacaton's award in 2025, as well as other prominent figures in the field, such as Kazuyo Sejima in 2023, Farshid Moussavi in 2022, and Yasmeen Lari in 2020.

The Afterlife of Expo Osaka’s Grand Ring: How the Timber Structure Is Being Reused Across Japan

Antonia Piñeiro — Wed, 18 Feb 2026 06:30:00 +0000

Exhibitions can be an opportunity to extend architectural discourse beyond professional circles, opening conversations with broader publics and serving as an interface between architecture and society. Within this concept, major international events such as the Osaka International Expo 2025 and the Venice Architecture Biennale have adopted the idea of the circular economy as one of their organizational objectives. The idea of circularity in events can be reflected in, for example, their energy consumption, the impact of the displacement they generate, their waste, or the useful life of their infrastructure. The site destined for the last World Expo, held in Osaka from 13 April to 13 October 2025, was surrounded by a massive timber structure designed by Sou Fujimoto Architects, one of the world's largest wooden constructions. The Japan Association for the 2025 World Exposition committed to reusing building materials "as much as possible," with concrete plans for their reuse to be finalized by March. In the meantime, some relocation alternatives are already emerging for the pieces of the World Expo structure.

Modern Spolia: Harvesting Building Materials from Demolition Sites

Mohieldin Gamal — Wed, 07 Jan 2026 04:00:00 +0000

The circular economy, including the reuse of building materials, is fast becoming a key component in the fight against carbon emissions. This involves designing to minimize waste and utilize materials that can be reused at the end of the building's life. On the opposing side, the reuse of materials from partially or wholly demolished buildings can also reduce waste and carbon emissions that would have resulted from using virgin materials. Sustainability purposes aside, the reuse of building materials has a centuries-old history, both for symbolic reasons and simply out of necessity.

From Material Intelligence to Circularity: Lessons from Architecture in 2025

Agustina Iñiguez — Tue, 06 Jan 2026 04:00:00 +0000

Which materials have taken center stage in the architectural discourse of 2025? Which projects have rediscovered new construction practices and methods through material innovation? While the future of building materials still appears uncertain, year after year, experimentation and research continue to reveal diverse practices, initiatives, and efforts dedicated to understanding their value and responsibility within the built environment. From agricultural waste that reduces carbon footprints to recycled plastics given new life, and living materials that engage with emerging technologies while reconnecting with nature, 2025 has highlighted and strengthened the role of architects as mediators between materials, disciplines, knowledge, and interests from diverse origins.

Extending the Lifespan of Materials: Circularity and Recyclability as Part of the Design

Agustina Iñiguez — Tue, 16 Dec 2025 06:45:00 +0000

What is the current global outlook on the recyclability of materials used in architecture? To what extent are contemporary societies truly committed to reducing environmental impact? In the effort to live in balance with nature, replacing fossil fuels with renewable energy sources is one of the key strategies for cutting greenhouse gas emissions and addressing global warming. Looking to nature for inspiration as a way to protect it means creating designs that incorporate sustainability, circularity, and recyclability from the very first sketch. From building systems to surface finishes, the use of biomaterials in architecture reflects a mindset rooted in long-term responsibility for a material's full life cycle.

Designing the Reuse Economy: How Architects Can Build Supply Chains, Not Just Buildings

Ananya Nayak — Fri, 21 Nov 2025 04:00:00 +0000

Across Europe and beyond, architects are confronting a turning point. As rising emissions targets collide with shrinking material supplies and the growing urgency of climate commitments, the built environment is being forced into a deeper reckoning with how it consumes, circulates, and discards resources. What was once considered waste is now revealing itself as a dormant architectural archive, an urban ecosystem of materials waiting to be reclaimed, revalued, or reimagined. Within this shift, architects are beginning to play a radically different role. Not only as designers of buildings, but also as orchestrators of the flows that sustain them.

From Overlooked Waste to Circular Opportunity: Plastics in Construction

Eduardo Souza — Tue, 14 Oct 2025 07:30:00 +0000

Like the famous Russian Matryoshka doll, opening a package often feels like uncovering endless layers. Inside a cardboard box, there might be molded Styrofoam, then several plastic air pillows, and finally, individual plastic wrapping around each piece. Even a small product can leave behind a trail of plastic waste far larger than its size. Now imagine this logic applied to a construction site where every component, every delivery of materials, often arrives wrapped in multiple layers of protection. What already seems excessive in retail becomes monumental when repeated daily on large construction projects.

Reimagining Lisbon’s Azulejos: Regenerative Biomaterial Tiles from the Tagus River

Enrique Tovar — Tue, 26 Aug 2025 06:30:00 +0000

All materials come from somewhere, embedded in a chain of extraction, supply, production, and disposal that, depending on its scale, leaves more or less significant marks on the environment. In architecture, we usually approach this trajectory through the lens of materials' circularity, considering how they can re-enter production cycles rather than become waste. Yet, broadening our view to unexpected places reveals parallel systems where by-products from one industry become resources for another. This approach has found fertile ground in organic waste transformed into biomaterials, with one of the most recent examples being the work of Fahrenheit Works. Through their installation, "From the Tagus to the Tile", they repurpose oyster shells initially discarded by food systems to create a reinterpretation of Lisbon's iconic tiles.

How Amsterdam Uses the Doughnut Economics Model to Create a Balanced Strategy for Both the People and the Environment

Maria-Cristina Florian — Thu, 07 Aug 2025 04:00:00 +0000

In 2020, in the midst of the first wave of lockdowns due to the pandemic, the municipality of Amsterdam announced its strategy for recovering from this crisis by embracing the concept of the “Doughnut Economy.” The model is developed by British economist Kate Raworth and popularized through her book, “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist”, released in 2017. Here, she argues that the true purpose of economics does not have to equal growth. Instead, the aim is to find a sweet spot, a way to balance the need to provide everyone with what they need to live a good life, a “social foundation” while limiting our impact on the environment, “the environmental ceiling.” With the help of Raworth, Amsterdam has downscaled this approach to the size of a city. The model is now used to inform city-wide strategies and developments in support of this overarching idea: providing a good quality of life for all without putting additional pressure on the planet. Other cities are following this example.

Nothing Is Lost, Everything Transforms: The Reusable Future of the Biennial’s Structures

Camilla Ghisleni — Wed, 11 Jun 2025 07:30:00 +0000

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.

Understanding Soft Architecture: The Shift from Monument to Moment

Diogo Borges Ferreira — Wed, 04 Jun 2025 07:30:00 +0000

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.
