Circular Design: The Latest Architecture and News

During the last week of August, the New York City government announced a new project for the MADE Bush Terminal in Sunset Park, Brooklyn. It involves the transformation of the old industrial building into a center for the recovery, storage, sorting, and redistribution of construction materials during a one-year pilot program. The initiative echoes a wave of similar circular construction hubs recently launched or announced across Europe: a converted warehouse in Brussels, an industrial site adaptation in East London's Royal Docks, and a cross-border network supported by CirCoFin spanning Munich, Copenhagen, Lisbon, and Scotland, each repurposing industrial buildings and infrastructure to support the reuse of construction materials.

What narratives do materials carry, and how can the visible "traces" of artisans engage in a dialogue with manufacturing processes and industrialization? Between design and construction, the act of thinking through making can become a guiding principle for a design philosophy. Combining wood, industrial materials, and reused objects, Atelier CRAFT's approach is rooted in reversible architecture, guided by its manifesto: "Transform design through making." Based in Saint-Ouen, Paris, the practice explores the relationships between humans and materials, the act of making, and manufacturing processes.

The center of a plan is never simply empty space. Once rooms and routes begin to organize around it, the center starts to structure the entire plan. It may contain a courtyard, a stair, a garden, or a shared room. It can also preserve something already present on the site or support a process that architecture does not fully control. What occupies this position determines how the surrounding spaces are arranged, connected, and used.

In A Pattern Language, Christopher Alexander, Sara Ishikawa, and Murray Silverstein describe shared spaces as most effective when they sit at the center of gravity of everyday life and remain connected to the routes people use most. Their argument suggests that a center matters not because it occupies the geometric middle, but because the surrounding rooms, paths, and activities give it spatial weight. The projects included here extend that idea beyond communal space, showing how the center can organize circulation, collective use, environmental systems, and the relationship between architecture and what already exists on the site.

Images of the benches at New York City's High Line Park spread around the world when the project opened in 2009. Emerging diagonally from the same material and modular pattern as the paving, they transition seamlessly from concrete to wood, evoking the railway tracks that once occupied the site. To withstand decades of exposure to the elements, the project required a wood species of exceptional durability, and ipe, harvested from the Brazilian Amazon, was selected. Its slow growth produces a dense, low-porosity hardwood that is naturally resistant to wear, moisture, and biological decay. The choice, however, sparked controversy at the time amid concerns over the certification of the timber's forest management. This broader view changes how we think about materials. Their origin still matters, but so does what happens after the building's life comes to an end.

Barcelona has just become the first city in the history of the UIA World Congress of Architects to host the event twice. Thirty years separate the two editions, and the distance between them says as much about architecture's changing self-understanding as anything spoken from a stage. In 1996, the congress placed the city at the center of the debate, consolidating a post-Olympic urban model that would go on to be studied and contested for decades.

In 2026, under the theme "Becoming. Architectures for a Planet in Transition," Barcelona hosted a very different conversation. The congress's curatorial team — Pau Bajet, Mariona Benedito, Maria Giramé, Tomeu Ramis, Pau Sarquella, and Carmen Torres — organized the program around six thematic lines: Becoming More-than-human, Becoming Circular, Becoming Embodied, Becoming Interdependent, Becoming Hyper-Conscious, and Becoming Attuned. As they told ArchDaily ahead of the opening, the premise behind this structure was that most architectural decisions are, in practice, very specific — which material is used, what is demolished or preserved, how much water or energy a building consumes — yet those specific decisions carry planetary implications.

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.

Can one of architecture's oldest materials still inform how sustainability and manufacturing are approached today? What shifts when ceramic is viewed beyond its surface, as a process shaped by light, water, and clay? At Milan Design Week 2026, VitrA, a brand producing bathroom and ceramic surfaces and working across sanitaryware and tiles, and international design practice Snøhetta explore these questions through Ceramics Forged in Light, an immersive installation created for the INTERNI MATERIAE exhibition. Positioned within a broader discourse on material experimentation and circular production, the project treats ceramic as an architectural material defined by continuous transformation, shaped through light, water, heat, reflection, and reuse.

Fired clay has been used in construction for over 9,000 years, evolving from vernacular craft into one of the most widely applied materials in the built environment. Its durability, water resistance, thermal performance, and adaptability have made it a staple for facades, sanitaryware, flooring, architectural surfaces, and structural systems. Today, new manufacturing technologies are extending these possibilities as architects and manufacturers confront the environmental implications of material extraction and production.

When walking into a large living space, a hotel lobby, or an open-plan workplace, the first thing that can be noticed is not what divides the space, but what holds it together. There are rarely clear boundaries, no obvious rooms, no strict partitions, yet the space still feels organized. Some areas invite a pause; others dictate movement; others foster community. The transitions are subtle, but legible.

At the same time, these interiors are expected to do more. They must accommodate constant change, withstand intensive use, and respond to environmental pressures by reducing waste, extending lifespans, and avoiding frequent replacement. The question is not only how a space looks, but how it performs over time. What is actually doing the heavy lifting?

Using massive s plates, often several centimeters thick and weighing tons, Richard Serra's sculptures convey an almost improbable sense of lightness. This effect does not result from a reduction of mass, but from how that mass is organized: large curved surfaces tilt, narrow passages compress the body, and seemingly unstable elements create a constant sense of imbalance. Serra transforms weight into a dynamic spatial experience.

In architecture, lightness has occupied a central role at least since the modern period. While earlier traditions, such as Greek and Roman architecture, were closely associated with stability, and large churches with monumentality, the twentieth century introduced a decisive shift in how matter is handled, particularly through the separation of structure and enclosure.

During renovation projects, replacement is often preferred over refurbishment. Used fixtures are removed, new products specified, timelines secured. Particularly in hospitality projects, where closures are costly and operations are tightly scheduled, installing new components appears to be the most reliable solution. It is faster, easier to coordinate, and aligns with established workflows. Refurbishment operates differently. It requires careful dismantling instead of disposal, evaluation instead of substitution, and trust in the quality of what is already there. It introduces complexity into a process designed for efficiency.

The recent renovation of Brenners Park-Hotel & Spa in Baden-Baden demonstrates that under the right circumstances, this additional effort can become a deliberate architectural strategy for similar projects, especially when the original materials were never intended to be temporary. 

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."

With the mass adoption of telecommunications networks in the twentieth century, cities around the world built large telephone exchange buildings filled with electromechanical equipment responsible for routing calls between regions. These structures were highly specialized pieces of infrastructure, often occupying entire city blocks and organized around large-scale technical machinery. With the transition to digital switching technologies and, later, the widespread adoption of mobile telephony, much of this equipment became obsolete within a few decades. The buildings themselves often remained structurally sound, but the systems they were designed to support had already evolved beyond them.

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.

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.

What if industrial leftovers weren't waste, but the start of architectural design? At Rieder's headquarters in Maishofen, Austria, over 1,300 cubic meters of timber, 180 ceiling elements, and hundreds of upcycled glassfiber-reinforced concrete fragments come together in a building shaped as much by reuse as by planning. The new production hall, designed by Kessler² Architecture, treats material leftovers as a design resource. Developed as part of a long-term investment in sustainable manufacturing, the timber-concrete hybrid building introduces a facade technique that inverts conventional architectural workflows: instead of designing first and producing components afterward, the building envelope is generated from the material remnants already available on site establishing a new language for industrial architecture.

Buildner is pleased to announce the results of its Architect's Chair Competition Edition 4, an annual international competition that invites architects and designers worldwide to submit designs for a signature chair. Following in the footsteps of iconic figures like Charles and Ray Eames, Ludwig Mies van der Rohe, Marcel Breuer, and Arne Jacobsen, participants are tasked with creating custom chairs that reflect their unique design philosophies and visions.

The pursuit of stronger, lighter, and more durable materials has guided architecture long before polymers or carbon fibers existed. One of the earliest large-scale examples of composite materials can be found in the Great Wall of China, where stone, clay bricks, and organic fibers such as reeds and willow branches were blended to create a resilient and lasting structure. These early techniques reveal a timeless intuition: distinct materials, when combined thoughtfully, produce properties unattainable by any single element. As the construction sector faces urgent ecological pressures, this intuition is being revisited through the lens of sustainability, with architects and engineers exploring bio-based, recycled, and hybrid composites designed not only for performance but also for circularity and environmental responsibility.

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.

In much of China, concrete remains the dominant construction material. Despite growing concerns over its environmental impact, concrete continues to align with the priorities of many developers and clients—it is fast, cost-effective, and highly durable. As a result, most building types in China still rely heavily on concrete. This reliance is further reinforced by China's position as the world's largest producer of Portland cement. A deeply entrenched supply chain, rooted in raw material manufacturing and economic infrastructure, ensures that concrete remains the default choice in the construction industry.

Yet historically, Chinese architecture was built upon a rich tradition of timber construction. The Forbidden City is a prime example: not only is it emblematic of China's architectural heritage, but it also remains one of the largest and best-preserved collections of ancient wooden structures in the world. This legacy prompts an important question: does timber construction have a meaningful future in China's contemporary building industry?
