Ecological Architecture: The Latest Architecture and News

At the UIA World Congress of Architects 2026 in Barcelona, the theme Becoming. Architectures for a Planet in Transition framed architecture as a discipline operating within environmental, political, and social transformations rather than outside them. Among the speakers participating in this edition was architect Andrés Jaque, founder of the Office for Political Innovation and Dean of Columbia University's Graduate School of Architecture, Planning and Preservation (GSAPP). During the Congress, ArchDaily spoke with Jaque about architecture's capacity to generate alternatives, the role of experimentation in education, and why transition should be understood as a condition rather than a destination.

MVRDV has won the international design competition organized by the social enterprise Shift to design the Shift Embassy, a new cultural destination planned for Rotterdam's developing Waterkant district. Conceived as a hybrid of architecture and landscape, the proposal, titled Rotterdam ROCKS! combines exhibition spaces, hospitality, education, public amenities, and ecological infrastructure within a publicly accessible building intended to support Shift's mission of engaging visitors with environmental and societal challenges. The project will form part of Waterkant, a large-scale urban development on the south bank of the Maas, planned to include 3,750 homes alongside schools, workplaces, cultural venues, and public spaces.

As Barcelona hosts the UIA World Congress of Architects for the second time in its history, thirty years after the 1996 edition, the city becomes a site for reflecting not only on architecture but also on the changing conditions under which it operates. Titled Becoming. Architectures for a Planet in Transition, and developed by the six-member curatorial team of Pau Bajet, Maria Giramé, Mariona Benedito, Tomeu Ramis, Pau Sarquella, and Carmen Torres, the 2026 Congress expands the discussion beyond the city toward planetary questions, addressing architecture through ecological, social, political, and material systems rather than as an isolated discipline. During the opening day of the Congress, ArchDaily spoke with Mariona Benedito and Carmen Torres, two members of the curatorial team, about how this edition revisits Barcelona's architectural legacy, why uncertainty has become central to architectural thinking, and what they hope participants will take away from the event.

Cities are increasingly designed to mitigate risk, and by doing so, need to collect data on climate, infrastructure, biodiversity, and social fragmentation so that the language of resilience becomes a fixture of planning. Yet the underlying conditions that produce polarization, civic disengagement, and ecological breakdown often remain unquestioned. The tools that dominate urban practice tend to address only one register of human experience, while the emotional and imaginative dimensions of transformation are not treated as reliable solutions.

Philosopher Felix Guattari proposed that sustained ecological transformation depends on simultaneous attention to three distinct ecologies: the ecology of the mind, the ecology of society, and the ecology of the environment. Mainstream environmental politics tends to concentrate on one or two of the three, flattening a complex condition into a defined problem with a clear answer. Ancient rituals remind us that transformation depends on practices that simultaneously engage the body, the community, and the environment.

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.

Architecture continues to draw cities as though humans occupy them alone. Plans trace circulation routes, zoning maps assign functions, and buildings are evaluated according to human comfort, safety, and efficiency. Walking through cities across India and Southwest Asia reveals something much more complex. Dogs sleep beneath market stalls, monkeys move across rooftops, birds nest in temple towers and mosque façades, and insects pollinate urban landscapes hidden in plain sight. These species are woven into daily urban life as consistently as human occupants. Streets, courtyards, roofs, drainage systems, markets, and vacant lots are already occupied by multiple species simultaneously. Architectural thinking has been slower to account for this reality.

"By 2050, almost every child in the world — nearly 2.2 billion children — will be exposed to frequent heat waves." UNICEF's warning is often read as a public health forecast, but it is also a challenge to architecture and the way cities are built. As extreme heat intensifies across Asia, Europe, and beyond, thermal comfort should not be reduced to merely an indoor service delivered by machines. Air-conditioning has become a life-support system for many cities, especially in dense, humid, and rapidly urbanizing regions. Yet to rely on it as the default answer is to treat heat as something that can simply be moved elsewhere (and in the process generating extra heat) — expelled from interiors into streets, service alleys, energy grids, and the atmosphere. Its expansion increases energy demand, produces waste heat, and reinforces unequal access to comfort.

Heat, however, does not stop at the human body. It reorganizes the wider urban ecosystem: trees struggle with compacted soil and radiant paving; birds and insects lose habitat when planting is reduced to decorative greenery; aquatic systems warm, microbial life shifts, and materials absorb and release heat long after the sun has set. Heat is not simply a climatic problem to be escaped indoors. It is an urban actor that reshapes public space, labor, mobility, planting, material choices, and the fragile relationships between human and nonhuman life.

This week's stories reveal a growing focus on reconnecting design with physical reality, whether through construction, landscape, public space, or collective participation. From the curatorial direction of the upcoming Venice Architecture Biennale 2027 to internationally recognized projects addressing flood resilience, affordable housing, and ecological restoration, many of the week's discussions challenged architecture's increasing detachment from material, environmental, and social conditions. At the same time, major cultural interventions, temporary structures, and public forums explored how institutions and civic spaces can become more accessible, adaptable, and engaged with everyday urban life.

In Latin America, the ground is rarely just a surface to build on. It can be a river edge, a steep slope, a humid forest floor, a floodable landscape, or a territory under ecological pressure, and in many cases, it carries a history of communities that already knew how to respond to it, building on stilts, on platforms, over water, long before contemporary architecture asked the same questions.

These projects continue that conversation. They engage with conditions that move, absorb, erode, and grow, rather than treating the ground as something to level or control. Elevation allows architecture to adapt without fully taking over: water can pass below, vegetation can remain, and slopes can keep their original condition. In each case, the decision to rise is tied to something specific: water, humidity, topography, vegetation, or ecological recovery, and the knowledge of how to build within it and not against it.

Costa Rica is a small country in Central America, internationally renowned for its tourism, biodiversity, and tropical climate. Given this context, tropical design strategies for hotel design are often more studied, but residential cabin projects can represent a more surgical approach to understanding the landscape. Often situated in remote forest or jungle locations, these cabins, apart from the common tropical design strategies, have to prioritize long-term durability and low-maintenance costs, particularly in regions where access for repairs is logistically difficult. This necessitates a design philosophy that favors both structural and climatic resilience.

Building in this context requires precise design responses to two primary environmental stressors: extreme precipitation and high humidity. Costa Rica's tropical climate, while varying by altitude, generally delivers an average monthly rainfall exceeding 150 mm in many regions. This constant water load can create a "wet-bulb" effect, where stagnant, saturated air accelerates interior material degradation and creates physiological discomfort for the inhabitants. To design effectively under these conditions, contemporary cabin architecture employs a three-fold strategy of minimal site invasion, the creation of thermal gradients, and passive climate mitigation.

Architecture has traditionally been described as a discipline concerned with space, form, and material presence. Yet this understanding becomes increasingly limited when confronted with the conditions that shape contemporary construction. Buildings no longer emerge from a stable relationship between site, program, and material. Instead, they are produced within a dense web of technological systems that operate across territorial, ecological, and temporal scales. Energy networks, data infrastructures, extraction processes, and global logistics shape architecture as decisively as climate or urban context.

Seen from this angle, architecture is less a discrete object than a moment within a larger technical field. Supply chains, data systems, automated maintenance, and energy grids do not sit "behind" the built environment. In a certain way, they influence what can be built, what is affordable, how buildings perform over time, and what kinds of waste they produce. When architecture is assessed primarily through form, it risks overlooking the systems that condition its production and afterlife.

Located in Istanbul, Türkiye, an 84-hectare neighborhood is currently under development in the Riva area of Beykoz along the city's Black Sea coast. The master plan has been developed by an international design team including Snøhetta, Bjarke Ingels Group, and MVRDV, alongside local practices KEYM, DB Architects, Rasa, and Bilgin Architects. Known as Ion Riva, the project is conceived as a landscape-led residential community that integrates housing, cultural facilities, and public programs within an ecological framework shaped by the meeting of forest, river, and sea. The first phase of the development, which has received planning permission and is currently under construction, will deliver 969 homes designed for approximately 3,000 residents, with the first completed residences expected to be occupied in 2027.

The concept of the technosphere provides a framework for understanding the scale of human impact on Earth. The term was coined by Peter K. Haff, and it is defined as the global network of human-made artifacts: a physical layer of infrastructure, buildings, vehicles, and machinery that functions alongside the biosphere and atmosphere. Currently estimated at 30 trillion tons, this human-constructed mass is dominated by the built environment. In this context, architecture serves as the primary interface, shaping how technology interacts with local ecologies. However, it seems that soon, the Technosphere will no longer be confined to the terrestrial surface. Through NASA's Artemis program, this network of human-made mass is expanding beyond Earth's atmosphere and is looking to establish new orbital infrastructure that represents the first permanent off-world extension of this man-made system.

Educational architecture remains an exploratory ground for unbuilt exploration, offering insight into how learning environments can evolve alongside changing social, ecological, and pedagogical values. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that examine schools, libraries, nurseries, and academic centers as spatial frameworks for care, knowledge, and collective growth. Rather than treating education as a fixed program housed within singular buildings, these projects approach learning spaces as adaptive environments shaped by landscape, climate, and human interaction.

Across varied geographies, from Mediterranean hillsides and Central European courtyards to tropical cities and distributed campus models, the proposals explore diverse architectural responses to contemporary education. They range from child-scaled kindergartens organized around trees and cloisters to libraries conceived as civic landscapes, biodiversity-centered academic buildings, and schools imagined as walkable urban systems.

The OBEL Foundation has announced "Systems' Hack" as the focus of its 2026 cycle, setting the conceptual framework that will guide the foundation's activities and the selection of the next OBEL Award. Founded in 2019, OBEL recognises architecture's potential to act as a tangible agent of positive social and ecological change, supporting approaches that expand how the built environment is defined and shaped. The 2026 theme calls on architecture to critically engage with the systems that underpin contemporary society, including infrastructure, energy, food, water, education, and information, and to examine how these interconnected networks might be reconfigured in response to accelerating global challenges.

What does it mean to practice ecological responsibility beyond performance metrics or carbon calculations? How can fabrication become a design method rather than a final outcome? Founded in Seoul, Yong Ju Lee Architecture is a practice led by architect and researcher Yong Ju Lee. Across installations, research-driven proposals, and cultural projects, the studio positions architecture as an experimental discipline rooted in making: a process in which design emerges from material behavior, prototyping, and fabrication logic as much as from drawing or representation. Bridging professional practice and academia, his work consistently expands the architectural toolkit through computational design, experimental material research, and an evolving commitment to ecology as a responsibility and a design driver. In 2025, the studio was selected as a winner of the ArchDaily Next Practices Awards.

Beneath the visible surface of cities lies an invisible architecture. Subways, tunnels, water systems, data cables, and bunkers form a dense network that sustains urban life while remaining largely unseen. The ground beneath our feet is not a void but a complex territory that holds the infrastructures, memories, and anxieties of our age. In recent years, as land becomes scarce and climate pressures intensify, architects and urbanists have turned their gaze downward, rediscovering the subterranean as both a physical and conceptual frontier. To design underground is to engage with the unseen mechanisms that shape the world above.

The subterranean has long been a site where architecture intersects with politics, technology, and belief. From the catacombs of Rome to the industrial subways of modernity, descent has symbolized both protection and exposure. Twentieth-century urbanism transformed this gesture into a system: metros, shelters, and utilities redefined the city section as an instrument of governance. Beneath the promise of efficiency and progress, the underground absorbed the anxieties of an era of war, surveillance, and collapse. Its evolution reveals not only how societies build, but also how they fear.

Today, the ground has become the new frontier of urban expansion and ecological adaptation. As digital infrastructures, energy systems, and climatic buffers migrate below grade, architecture confronts a space both technical and metaphysical — essential yet marginal, invisible yet decisive. To think in sections rather than in plan is to recognise that contemporary cities no longer exist solely in their skylines but also in their depths. The challenge for architecture is not only to occupy that space, but to render it legible, to turn the unseen into knowledge, and the hidden into a new terrain of design.

Buildner has announced the results of the Howard Waterfall Retreat architecture competition, an international design challenge developed in close collaboration with the Howard Family Trust. The competition invited architects and designers to propose a multi-generational family retreat set within a privately owned, forested landscape in Northwestern Pennsylvania, centered on the dramatic presence of Howard Falls and the surrounding gorge.

Rather than prescribing a singular architectural solution, the brief emphasized a careful dialogue between architecture and nature. Participants were asked to consider how a retreat could balance shared and private living, respond to steep topography and water systems, and integrate sustainably within a sensitive ecological setting. The project also called for an interpretation of family legacy, encouraging designers to acknowledge the history of the site and the original summer cottage while imagining a retreat capable of evolving across generations.
