Sustainable Architecture: The Latest Architecture and News

As cities change, so do our expectations of them. People are asking for more caring spaces: public places open to all ages and genders, nature within reach of every social class, and settings that foster connection. Few design intentions hold these together as well as spaces for children. This selection of unbuilt projects submitted by ArchDaily readers showcases different approaches to care-based architecture. Schools, daycare centers, a library, a youth center, and a new model for orphanages take on the mission of providing a safe and stimulating environment for children at every stage of their development. Not yet built but carefully designed, these proposals offer a glimpse into spaces for play, learning, and calm that fuel creativity in design for people of all ages.

India's stepwells are usually encountered after their useful lives have ended. They are photographed, restored and interpreted as evidence of a water culture that once existed. Beneath the carved stone and descending stairs is a practical question: what happens when a structure built to manage water is put back to work? As Indian cities face water stress, seasonal rainfall and pressure on municipal systems, researchers and restoration efforts are examining whether traditional water structures can function again.

Traditional water architecture was rarely an isolated object. In Ahmedabad, water management was embedded in the organization of the city. Within the historic pols, wells, courtyards and underground Tankas formed part of a distributed system of domestic and communal water storage. A 2026 study in Built Heritage estimates that nearly 10,000 Tankas may still exist across Ahmedabad, many located beneath domestic courtyards.

Architecture firm HENN has launched CarbonBudget, a digital tool that calculates project-specific CO2 budgets for buildings. The new platform, free of charge, is a contribution for designers to help reach the 1.5°C target, a global goal from the Paris Agreement to limit long-term global warming to 1.5°C above pre-industrial levels. As the construction industry is responsible for around one-third of global CO2 emissions, architectural design decisions can effectively contribute to containing global warming. The tool is designed to calculate whether the emissions of a building project located in Europe are compatible with the Paris Agreement target, based on specific inputs such as location and building area. The new platform joins other projects from international offices such as MVRDV NEXT's CarbonSpace, Grimshaw's Minoro, and Henning Larsen's OpenDetail, addressing decarbonization through shared digital information.

In the face of the climate crisis and within the framework of the United Nations Sustainable Development Goals, the reuse of materials has become prominent in the fields of construction and architecture in recent years. From "urban mining" to life cycle assessments (LCAs), professionals, organizations, and researchers are exploring different solutions and strategies to address the same overarching challenge. Project (Un)Build is a research initiative developing reversible timber construction methods that use straps and friction pads to facilitate material reuse. It contributes to the ongoing debate and reflection on the act of building itself.

In 1948, Robert Moses established the Fresh Kills Landfill on the western shore of Staten Island. The site, chosen for its remote marshland and cheap land value, was meant to be temporary, but by 1955 it was the largest landfill in the world, receiving up to 29,000 tons of refuse per day at its 1991 peak. By 2001, after more than fifty years of continuous operation, Fresh Kills covered 2,200 acres, roughly three times the area of Central Park, and was, unspectacularly, visible from space. When it started, Moses didn't expect to design a dump but, without calling it that, a new landform with four artificial hills rising up to sixty meters above sea level built entirely from the accumulated residue of eight million daily lives.

That landform is now, slowly, becoming a park. James Corner Field Operations won the international design competition launched by the city in 2001, producing a master plan called Lifescape that will take thirty years to complete. The landfill's four mounds are being capped, planted, and gradually opened to the public. Methane from decomposing waste is captured and fed into an energy system as the wetlands are being restored around the engineered hills. Evidence of New York's consumption transformed into a feat of ecological engineering and an act of institutional memory management (a way of making a city's most embarrassing landscape slowly look like something it was always meant to be).

"Let us take a hard look at the facts." With this direct and hardly reassuring sentence, the director of the Office of Civil and Defense Mobilization opened The Family Fallout Shelter, a 32-page manual published by the U.S. government in 1959 amid Cold War tensions. The document taught families how to build shelters capable of protecting them from radioactive fallout after a possible nuclear attack and, through technical drawings and sketches, outlined solutions using concrete blocks, walls filled with earth or sand, underground structures, and ventilation systems. It was a survival manual that, in many ways, also functioned as a construction manual.

In many Asian cities, the summer climate can increasingly be experienced from a distance. In Hong Kong, it is possible to move from an apartment tower through a podium mall, enter the Mass-Transit-Railway system (MTR), arrive beneath another commercial complex, and continue through enclosed footbridges or underground passages while encountering remarkably little of the atmosphere outside. Heat, humidity, rain, and seasonal variation remain present, but they can be largely bypassed through a continuous network of conditioned interiors.

Over several decades, air-conditioning has expanded from a technology for cooling individual rooms into an infrastructure capable of producing an alternative urban environment. This has been particularly visible in parts of East Asia and South East Asia, where transit-oriented development frequently combines railway stations, shopping centres, housing, offices, and other everyday services within interconnected complexes. The Railway plus Property model has helped institutionalize this relationship between transport and development, creating districts where movement through the city is often inseparable from movement through privately managed interiors.

The landscape and scattered settlements of Ireland carry a reputation for wildness. Rugged cliffs meet the Atlantic, green fields roll across the interior, and rain and wind change the scene by the hour. A closer look reveals a worked terrain as historic stone walls divide agricultural fields, roads and paths connect towns to the coast, and castle ruins alongside cottages record centuries of occupation. Change is the expected condition of the island, shaped as much by human hands as by geology and weather, and the practice of treating the existing context as material to adapt and modify runs deep.

Ireland has a large inherited building stock, from vernacular cottages and farm compounds to Georgian and Victorian urban terraces, while a growing share of it sits vacant or derelict as housing remains scarce and expensive. Planning and heritage protections shape what can be altered, while growing attention to embodied carbon makes demolition increasingly difficult to justify. Under these pressures, design strategies for renovation are one of the most inventive areas of contemporary Irish design. Architects cut into old structures to admit light, set new materials against aged ones, and redesign buildings for contemporary lives and routines.

Buildner has announced the results of the Iceland Slow Sauna architecture competition, developed in partnership with Slow Travel Mývatn. Set beside Þúfa – Private Homestay in the volcanic landscape of Lake Mývatn in northern Iceland, the competition invited architects and designers to create a compact retreat combining a sauna and greenhouse within a single architectural experience. Rooted in the Icelandic tradition of bathing as a ritual of stillness and renewal, the brief asked participants to explore how heat, light, vegetation, and landscape could shape an intimate place of recovery and connection to nature.

There are two unique things about being human that made us survive the early years and spread over the whole planet: sweating and storytelling. Sweating helps cool down the body when running long distances. Stories help us collaborate in big numbers and share knowledge across groups and generations. As architects, we still rely on the same tools to make visions become reality.

As professor of stories Angus Fletcher points out in his book Primal Intelligence, there is a common misconception about the role of stories: when our "rational" brain has developed an idea that we fail to explain to a wider group, we pack it into a story, and suddenly everybody understands. Fletcher argues that it actually works the other way around: ideas come from stories, our brain works in stories, and stories form reality. Architects have a derogatory term for turning that process the wrong side up: "post-rationalisation", for example when diagrams are made to explain a design that is already decided.

There is no shortage of ways to imagine what the world will look like after a climate catastrophe. Genres of movies and novels have been built around the question of what happens when contemporary safeguards fail, from dystopian fiction and post-apocalyptic literature to disaster films, graphic novels, and video games. Burning forests, submerged cities, abandoned infrastructure, resource scarcity, and mass displacement are a familiar visual and narrative vocabulary. We have become remarkably fluent in imagining the consequences of a world that fails to respond to climate change.

There is no harder place to build than a high mountain, and none where a building feels more provisional. From the Andes to the Himalaya to the Alps, high-altitude construction strips architecture back to its most elementary transactions. The rock reads as permanence itself, yet a structure set near the limit of habitation exists in negotiation with almost everything around it: with wind that arrives without obstruction, with a ground too steep and too frozen to excavate, and with everything it needs arriving from far below. What can be carried up, what can be assembled by few hands, and what can sustain itself are some of the terms of the problem.

Those constraints have produced a remarkably consistent building culture across otherwise unrelated ranges. The refuge, the hut, the bivouac, and the observatory belong to a shared typology in which shelter is inseparable from logistics, and where lightness, prefabrication, and self-sufficiency were structural necessities long before they became virtues.

3rd International Seminar on Territory, Urbanism, and Architecture Research – SIITUA III

Sustainability in architecture is often discussed as though it were a universal standard—and, in principle, it should be. Buildings are increasingly evaluated through energy performance, embodied carbon, certification systems, material efficiency, biodiversity, and whole-life impact. Yet the rules determining what must actually be done remain highly local. A project designed in London, New York, or Copenhagen may be shaped by stringent energy codes, environmental review, disclosure requirements, planning controls, and increasingly ambitious carbon targets. The same practice working elsewhere may encounter a very different regulatory landscape.

This creates a difficult question for international architecture: when sustainability is not enforced to the same degree by law, what standards should architects carry with them?

What can a textile do that glass, wood, concrete, or metal cannot? Architectural composite fabrics don't replace conventional building materials. Instead, they can complement them and often add another layer of performance to the building envelope. Their application changes with context. A composite membrane can become an exterior shading system for a tropical conservatory, an interior skin that shapes acoustics and spatial experience in a museum, or part of a facade strategy that improves the environmental performance of an existing building.

ArchDaily is proud to announce the winners of the 2026 Next Practices Awards, recognizing 20 emerging and forward-thinking practices expanding the possibilities of architecture today.

Now in its sixth edition, Next Practices continues to look beyond conventional definitions of the profession to identify the people, ideas, and methodologies driving the discipline. The 2026 edition is our strongest and most globally representative to date, bringing together different approaches, scales, and contexts that broaden our understanding of how and by whom architecture is being practiced.

From extreme climates to rural communities, informal cities, and territories affected by displacement and environmental vulnerability, this year's selection engages with a wide range of realities. Drawing from engineering, ecology, digital fabrication, material research, vernacular and Indigenous knowledge, advocacy, and critical research, these practices reflect what is "next": the capacity to respond to specific conditions and actively shape the world around them.

Stefano Boeri Architetti has won the competition launched by Spain's Entidad Estatal de Vivienda, Casa 47, for a new affordable housing development in Ibiza. Named "Sa Casa," the project proposes approximately 190 below-market-rate rental apartments distributed across four residential volumes. The scheme combines a prefabricated timber construction system with adaptable housing layouts and shared open spaces, with the design organized around the relationship between the residential buildings, landscape, and public areas.

How can daylight tackle global challenges? This question lies at the heart of Light of Tomorrow by VELUX, a global student competition that encourages architecture students to explore the future potential of daylight in the built environment. In its 12th edition, the competition received hundreds of responses from around the world, culminating in eight finalist projects presented to an international jury at the UIA World Congress of Architects in Barcelona. The 2026 global winner, Sun the Quilt, developed by students from Xi'an University of Architecture and Technology in China, was chosen for its strong concept, design thinking, and innovative use of daylight that transforms an everyday domestic ritual into an innovative facade system shaped by daylight, climate, and care.
