The Andes are often understood as a continuous mountain range, yet they encompass a wide range of climates and ecosystems. In Ecuador, Peru, Bolivia, Colombia, and Chile, páramos, dry highlands, temperate valleys, and snow-covered landscapes can exist within relatively short distances of one another. As elevation changes, so do temperature, solar radiation, humidity, wind, vegetation, and topography, producing environments that require different ways of building.
Unlike many mountain regions where cold is the defining environmental condition, high-altitude environments in the Andes combine several climatic conditions at once. As elevation increases, solar radiation becomes more intense. Some regions remain humid throughout the year, while others experience prolonged dry seasons. In many places, steep terrain, snow, and changing weather patterns become additional factors that influence how buildings are designed.
Across different climates and building cultures, many contemporary projects are working with local ways of building in new ways. Earth walls, bamboo structures, shaded thresholds, and collective construction processes are being reconsidered not as references, but as tools for the conditions architecture is facing now and will continue to face.
In these projects, vernacular knowledge appears through practical decisions: how to cool a building without machines, how to build with what is nearby, how to make a structure easier to repair, and how to keep construction knowledge within the community that will use it. The conditions making this knowledge necessary are not coming. They are already here.
A building material rarely begins where architecture encounters it. By the time concrete reaches a construction site, its limestone has already been quarried, processed, and transformed. Timber arrives long after the forest. Glass appears detached from the sand from which it was made. By the time materials enter construction, much of the landscape and industry that produced them has already disappeared from view.

While human life depends heavily on plants for the medicines, building materials, and fuel they provide, they also play a vital role in many ecological processes. From climate regulation through carbon dioxide absorption to soil fertility and the purification of air and water, plant diversity offers opportunities to address some of the most pressing challenges of this century, including food security, energy availability, climate change, and habitat degradation. In this context, botanical gardens act as living refuges that foster innovation, adaptation, and human resilience. But what can architectural practice learn from botany and its methods?
In the field of architecture, however, this question remains relatively marginal. We often know who designed a building, its finishes, the manufacturer of its frames, the brand of its wall coverings, and even its energy performance, but we almost never ask where the tons of material that made its existence possible actually came from.
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.
The curatorial team behind this edition, formed by Pau Bajet, Maria Giramé, Mariona Benedito, Tomeu Ramis, Pau Sarquella, and Carmen Torres, approaches architecture as a critical and transformative tool rooted in territory, working across practice, research, and teaching. Their program structures the Congress around six interconnected thematic lines (Becoming More-than-human, Becoming Circular, Becoming Embodied, Becoming Interdependent, Becoming Hyper-Conscious, and Becoming Attuned) and distributes it across three venues of very different characters — Les Tres Xemeneies del Besòs, the Disseny Hub at Glòries, and the CCIB — each chosen for what it represents as much as for what it can hold.
Contemporary architecture has learned to celebrate living matter. Mycelium panels, algae systems, living walls, life is now welcomed into buildings, framed as innovation. Yet the same discipline that celebrates these organisms treats mold as contamination. Both are biological. Both respond to moisture, temperature, and material conditions. The difference is not scientific. It is about which forms of life architecture is willing to accept, and which it prefers to remove.
Mold is not limited to abandoned buildings or poorly maintained interiors. It appears in homes, schools, offices, historic structures, and new construction, across different climates and contexts. This makes it harder to ignore as a minor or isolated problem. If mold keeps returning, what is it telling us about the environments buildings create?
When we think of façades, we rarely think of them as habitats. We see them as the elements that separate interior from exterior, regulate temperature, reduce noise, and protect buildings from external conditions. They give architecture its visual language, but they are also expected to keep the outside world at a distance. In doing so, façades have often been understood as barriers: surfaces that define where human comfort begins and where the environment is meant to remain outside.
But the outside of a building is never empty. For centuries, architecture has unintentionally created opportunities for other forms of life. Birds nested beneath roof tiles, insects occupied cracks in masonry walls, and mosses or plants took root along ledges, gutters, and rough stone surfaces. These conditions were rarely designed with other species in mind, but they created small opportunities for life to inhabit them.
As Europe experiences one of its earliest and most intense heatwaves in recent years, World Environment Day 2026 arrives amid renewed discussions about climate adaptation, urban resilience, and the capacity of cities to respond to increasingly extreme temperatures. Across Portugal, France, Italy, Spain, Germany, Switzerland, Ireland, and the United Kingdom, temperatures have surged well above seasonal averages, prompting heat alerts, school closures, emergency planning measures, and growing concerns about the performance of buildings and public infrastructure under prolonged heat stress. The convergence of these highlights a reality that is becoming increasingly worldwide: climate change is no longer solely an environmental concern but an issue that is fundamentally reshaping the spaces where people live, work, and gather.
The figure of Tithonus in Greek mythology offers a reflection on the paradox of permanence. In pleading with Zeus for immortality, he forgot to request eternal youth, resulting in a life of endless aging. Over time, his body deteriorates, turning immortality itself into a burden. The narrative suggests a fundamental contradiction: permanence, when detached from the capacity for change, ceases to be a desirable quality. Instead of stability, it produces accumulated decay without adaptation.
Historically, architecture has often fallen into the "Tithonus Trap." Materials are specified to resist time, systems are detailed to prevent change, and buildings are conceived as fixed images. Yet, this pursuit of the static rarely survives the reality of the elements. Between the moment of design—often associated with precise and controlled representations—and the lifespan of a building, surfaces inevitably weather, shift in appearance, and lose their initial finish. Aging is often interpreted as loss rather than as part of the architectural language.
In Six Memos for the Next Millennium, Italo Calvino explores lightness from a literary perspective and argues, "Opposed to lightness is weight. Removing weight produces lightness; it is a value, not a defect." Drawing on Greek mythology, he reflects on one of Perseus's feats after severing the head of the terrible Gorgon Medusa without being turned to stone. Assisted by the gods Hades, Hermes, and Athena, Perseus flies with his winged sandals and uses a bronze shield as a mirror to reflect her image. Relying, like many architects, on what is lightest—the wind and the clouds—he also fixes his gaze on what is revealed through indirect vision: an image reflected in a mirror.
Historically, transparency has been naturalized as an inherent condition of modern architecture. With the shift from the heavy load-bearing wall to the lightweight glass envelope, glass was introduced into the discipline, blurring the boundaries between interior and exterior spaces. In connection with inflatable architecture, transparency is linked to lightness and impermanence, leaving temporary traces on the landscapes it inhabits. By using textiles or plastics as main materials and air as a structural system, the search for lightness in the built environment now recognizes more than a single atmosphere of application.
Ecuador's territory embraces a remarkable diversity of landscapes, ranging from the Pacific Coast to the peaks of the Andes, the vast expanse of the Amazon rainforest, and the volcanic Galápagos Islands. Each region of the country presents its own distinctive characteristics, reflected in its varied environmental, cultural, and social contexts. While Latin American architecture is rooted in rich ancestral traditions, native construction techniques, and local materials, contemporary Ecuadorian architecture expresses an evolving identity that blends these elements with actual demands. Tradition and innovation, local resources and modern techniques, along with social responsibility and aesthetics, interact with the natural environment, urban conditions, and social contexts.

The well-known phrase "man is what he eats" (Der Mensch ist, was er isst), by Ludwig Feuerbach, asserts that the physical, mental, and even moral constitution of human beings is directly linked to what they consume. Today, this idea is widely internalized, with growing awareness around food, nutrition, and the impact of what we ingest on our bodies. Yet, this same level of awareness doesn't extend to the environments we inhabit, where materials continue to be treated as technical decisions rather than active agents in the relationship between body and space. Considering that a large portion of the global population spends around 90% of their time indoors, it is rarely discussed what actually composes these spaces at their most fundamental level: materials. Walls, floors, and finishes are often approached as technical or aesthetic choices, when in reality they can function as continuous sources of exposure to potentially harmful substances.

Having thrown a stone today, Eshu kills a bird of yesterday. The Yoruba proverb tells both a story of reparation and of ancestrality by joyfully bending spacetime conventions and accessing subjects from the past with present actions. The saying offers a poetic entry point to broader West African traditions and to the practice of Scottish-Nigerian artist and architect Dele Adeyemo. Named one of the winners of the ArchDaily 2025 Next Practices Awards, Adeyemo's work brings together ecology, spirituality, dance, and territory, examining how embodied cultural practices can generate alternative spatial possibilities within and against the architecture of racial capitalism.
Born in Nigeria and raised in the United Kingdom, Adeyemo has been visiting Lagos for many years. Through this engagement, he has developed an extensive body of research on collective movement practices that predate capitalism and offer distinct, often imaginative spatial intelligences operating alongside dominant systems. ArchDaily spoke with Dele about his artistic and pedagogical practices, and how he identifies design sophistication where architects often perceive deficiency.
In temperate and cold climates, architecture typically begins with a defensive gesture. The building envelope is a sealed boundary designed to resist the exterior environment through insulation, vapor barriers, and mechanical control. In cold countries like Canada, where winter temperatures can plunge well below freezing, airtightness is not a luxury. In this context, buildings must resist the exterior environment entirely to maintain interior comfort. However, in Central America, a region spanning from Belize to Panama, architectural logic shifts from exclusion to negotiation. In this region, the envelope is not a wall of defense but a specialized filter.

Some of the most significant transformations of South American landscapes have been produced not by cities, but by large infrastructures built to extract and distribute natural resources. Mining operations, energy systems, and transport networks have connected remote landscapes to broader economic structures while transforming rural territories and urban settlements throughout the continent. These infrastructures do not simply occupy space; they reorganize it. They have not only supported economic growth but also reconfigured territories in ways that continue to generate political, environmental, and social debate across the continent. From this perspective, territories can be understood not as fixed geographic areas but as socio-ecological systems shaped by cultural, environmental, and political relations, a point emphasized by anthropologist Arturo Escobar in his work on territorial thinking in Latin America.
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.
Decades later, the question was updated at the 7th Lisbon Architecture Triennale. Curators Ann-Sofi Rönnskog and John Palmesino asked: How heavy is a city? The scale shifted from the domestic interior to the territory. The technosphere, materialized in the estimated 30 trillion tons of human-made matter on Earth, reframes the discussion entirely. Cities, data centers, oil fields, logistics hubs, satellites, cables, and waste streams form a planetary system in which architecture is neither object nor backdrop, but participant.
