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.
Beyond ongoing debates surrounding prefabrication, reuse, and glocalization, material definition in architecture today, more than ever, seeks a balance between innovation, tradition, efficiency, and identity. In a world marked by constant change and evolution, the study of material life cycles, the integration of circular construction practices, and the development of material intelligence—among other variables—aim to guide architecture toward more resilient, environmentally conscious, and livable futures. The choice of materials in a project, as well as its construction system, has the power to shape spatial experience and convey values that extend beyond comfort and interior well-being.
From examining the origin of materials and the time required for their production and application, to assessing the social and environmental impacts of supply chains and material longevity across territories, architecture is actively seeking positions that respond to the environmental crisis from multiple angles. As articulated by the concept of Slow Architecture, which calls for a deep reassessment of material and construction choices based on an ethics of time, techniques such as Wang Shu's reuse of demolition materials or the integration of traditional systems in dialogue with contemporary technologies contribute not only to sustainable construction but also to preserving material memory and honoring craftsmanship.

Converging Architectural Trends in 2025: Circularity, Biomaterials, and Carbon-Conscious DesignAcross a wide range of projects, installations, research initiatives, laboratory experiments, and critical studies, solutions involving food waste applications, the conscious use of resources, minerals, reused plastics, and carbon-calculation tools stand out among the many paths explored throughout the year. Regardless of geographic or cultural context, each material represents a new opportunity for research.
Beyond Their Useful Life: Materials That Support a Circular Economy
In an effort to shape the architecture of the future, a range of initiatives, projects, standards, and regulations are promoting the adoption of circular approaches in construction. While early material cultures already demonstrated subtle forms of circularity, contemporary architectural practice continues to rethink the processes and methods that give rise to buildings. By recognizing plastic, food, and demolition waste as valuable resources for the industry, professionals from multiple disciplines—along with companies, agencies, and institutions—are driving this gradual shift, focused on respecting material cycles while addressing sustainability and reducing the environmental impact of construction.

From Organic Waste to Biomaterials: Addressing Carbon Emissions Mitigation and Resource-Conscious Approaches
As the fight against carbon emissions intensifies, material reuse is widely recognized as a key strategy for reducing waste and extending the lifespan of buildings. However, it is not the only path toward achieving this goal. Full-scale prototypes, installations, and pavilions made from living materials, agricultural byproducts, and other alternative resources encourage experimentation and research, guiding architecture toward more environmentally responsible construction practices. Just as sugarcane bagasse is used to build a school in India as a low-carbon alternative to conventional brick and concrete block construction, the Canada Pavilion at the Venice Biennale is centered on marine cyanobacteria capable of capturing carbon and contributing to the material growth of the structure itself. In this way, these projects invite a rethinking of architecture as a living, evolving process—one that imagines alternative futures and actively participates in planetary repair.

Advances in Technology: Redefining the Role of Materials in Construction
At the intersection of science, technology, and design, innovation in construction materials involves applying principles and knowledge that often include interaction with and experimentation in biological, chemical, computational, and related processes. For years, devices, structures, and software have supported the work of many architecture professionals focused on material manipulation and creation as part of their creative practice. Just as metamaterials offer properties rarely found in nature, this year highlights how diverse tools such as 3D printing, artificial intelligence, and robotics are moving beyond purely optimization-driven roles to open up new design pathways that add value to regenerative approaches.
