An opening between two rooms shapes how people move through a building, what they see from one space to another, and whether an area feels connected or separate. Although doors are among the most frequently used interior architectural elements, their impact on the interior organization is often considered late in the design process. Yet their movement and relationship to surrounding surfaces influence circulation, furniture placement, and the perception of space.

In residential renovations, these decisions are particularly important. Existing walls, structural elements, building services, and ceiling heights can limit options, while new layouts often balance open-plan living with the need for privacy. In new construction, architects have greater freedom to coordinate wall cavities, suspended ceilings, and door mechanisms from the outset.

When the Ostrogoths besieged Rome in 537 AD, their first military act was to cut the aqueducts. Eleven gravity-fed channels supplied the city with up to a million cubic meters of water per day, more than enough to sustain a population of over a million, fill the public baths, and scour the sewers. Without the aqueducts, Rome became a fortified enclosure around a contaminated river, proving that water was essential to the city's existence.

Unlike land, which can be fenced off, or oil, which can be stored, water is a resource that nobody can fully own, yet everyone depends on. It moves through aquifers, across borders, and down rivers. The Romans were cognizant of this fact; as the aqueducts constituted public infrastructure, the water flowing into fountains was accessible to all. Frontinus, the administrator who oversaw Rome's water system in the first century AD, documented every allocation, every illegal connection, and every abuse of the system with the rigor of someone who understood that water management was a civic act. Architecture, in this sense, has always had the capacity to make water a common good, and equally, by the same means, a privilege.

Direct contact with a material allows one to appreciate textures, compare finishes, and observe how its appearance changes under different lighting conditions. At an exhibition, these possibilities are complemented by exchanges with manufacturers and professionals, helping to understand applications and resolve questions about their use. This relationship between material exploration and architectural practice was one of the central pillars of the seventh edition of Obra Blanca, which drew more than 23,000 professionals to Expo Santa Fe in Mexico City.

Inhabiting a space involves multiple economic, social, cultural, geographic, political, and environmental factors. Beyond these considerations, however, it engages with processes, boundaries, and possibilities that have repeatedly become subjects of architectural inquiry. "We are builders of a society," declared Solano Benitez during his lecture titled The Place of Architecture at the Buenos Aires International Architecture Biennial. Through a series of international lectures, exhibitions across different locations in the city, and activities open to all generations, the 20th Buenos Aires International Architecture Biennial examined the value of inhabitation, recognizing architecture as the discipline that gives meaning to how and where we live and, consequently, how we exist within society.

Across its six main venues and numerous partner institutions, a common theme emerges: human existence explored through different ways of inhabiting, sharing knowledge, contrasting experiences, and debating the contemporary challenges facing architecture.

A canyon is a space no one designed. Its walls expose layers of rock deposited over millions of years, and the passage between them exists because water slowly wore that rock away. Glaciers shaped valleys in a similar way, leaving slopes behind as the ice retreated. Long before architects began shaping spaces, the Earth was already producing them.

Architects have long looked to the ground for geometry. A cliff can suggest a section, a cavity a room, and layered rock a way of stacking material. Some architects build directly into an existing formation, occupying a slope or a cavity on site. Others study a formation and reproduce some of its characteristics elsewhere, from precise geological data to the general experience of a landscape.

Wood has been used in buildings for thousands of years. It is natural, renewable and versatile, but its response to moisture requires consideration in design and specification. Changing moisture conditions can cause it to swell and shrink, while prolonged moisture exposure can create conditions for fungal decay. Historically, using wood outdoors has therefore meant choosing naturally durable species, protecting the material or designing around the way wood behaves. Wood modification offers another approach: changing certain properties of the material itself.

Every large dam divides as much as it connects, and the Grand Ethiopian Renaissance Dam is no exception. A monumental feat of architecture and engineering, the mega-dam has brought everyone together, for better or worse, to interrogate who gets to declare sovereignty over the riches of the river, be it water or momentum, and to challenge colonial-era Nile treaties.

Inaugurated in September 2025, the Grand Ethiopian Renaissance Dam, or GERD, is a grand concrete structure on the Blue Nile in western Ethiopia within the Benishangul-Gumuz region, just 30 kilometers upstream along the river and east of the border with Sudan.

It is built as a major source of hydroelectric power, being consistently ranked in the top 3-30 globally, and symbolizes Ethiopia's national sovereignty, rise to exponential economic development, and technological self-determination. So, why has it become the center of a protracted dispute over regional water security and international law between Ethiopia, Sudan, and Egypt?

At Bishan–Ang Mo Kio Park in Singapore, a river does not occupy a fixed boundary. Under ordinary conditions, water moves through a naturalized channel bordered by grass, planting, and paths that bring visitors close to the river. During heavy rainfall, water spreads into the surrounding park, which is designed to accommodate flows beyond the capacity of the narrower channel. What appears to be a public landscape is also working infrastructure. Singapore's approach retains drainage engineering while assigning a wider role to the land around it.

For decades, Singapore's network of concrete canals has been central to managing stormwater in a densely developed city exposed to intense tropical rainfall. Their hard surfaces and defined channels were designed to convey water efficiently. These channels moved stormwater efficiently, but offered limited space for public access, planting, or other uses along the water's edge. Through its Active, Beautiful, Clean Waters (ABC Waters) Programme, launched in 2006, Singapore began integrating waterways with parks, ecological systems, and public spaces. The programme links stormwater management with the design of parks, waterways, and public spaces.

Throughout history, people have sought ways to see the world. In Renaissance painting, linear perspective made this impulse explicit by transforming the canvas into a window, organizing depth from a fixed viewpoint. In his treatise De Pictura (1435), Leon Battista Alberti described painting as a window onto what one wishes to represent. Landscape, in this sense, ceased to be simply what lay before the eyes and became a visual construction, a reality selected and organized by the gaze.

Architecture operates in much the same way. A window determines what can be seen, from where it is seen, and, consequently, what becomes part of everyday experience. This question was central to modern architecture and found one of its most emblematic debates in the 1920s.

Adding new floors on top of a historic building presents a challenge beyond accommodating additional space: how can a contemporary intervention respond to the character of an existing structure? Material selection plays an important role in establishing a relationship between different construction periods, whether the aim is to complement the existing building or create a more distinct architectural expression. The LH Residence in Varna, Bulgaria, designed by STARH, offers an example of how fiber cement can help relate a contemporary addition to a historic building.

In 1972, Robert Venturi, Denise Scott Brown, and Steven Izenour published Learning from Las Vegas, challenging architects to reconsider the underappreciated, largely dismissed commercial landscape in the United States. Their storied distinction between the "duck," a building whose form communicates its meaning, and the "decorated shed," an ordinary structure whose identity is conveyed through signs and symbols, questioned a widely accepted modernist assumption that architectural expression should emerge from form and function. By examining billboards, neon lights, casinos, and the commercial strips of Las Vegas, the authors argued that architecture should study the visual languages of American consumer culture.

The concept of "eyes on the street" is perhaps the most famous within architectural and urban literature when it comes to urban security. Jane Jacobs uses this expression to refer to people who - consciously or unconsciously - use public spaces or observe them from their homes, generating natural surveillance. A movement that, within our discipline, is encouraged both through quality public spaces and through the powerful relationship between the public and private created through building facades. Advocating for this daily control, Jacobs believes in a way of making architecture and cities that condemns excessive verticalization, reinforced by isolated buildings and single-use ones that deny contact with the street.

Buenos Aires is a city of rich history and distinct atmospheres. There are many reasons to explore its architecture: the city is the result of a complex interplay of cultural factors shaped by a multitude of architectural styles and trends. Its streets and heterogeneous buildings define its inhabitants, reflecting an identity forged by its history.

Beyond its historic and heritage buildings, the city offers a remarkable diversity of modern and contemporary architecture. Indeed, its architectural highlights are easily discovered on foot, framed by its prominent and beautifully designed green spaces. Below is a list of 31 sites that every architect should visit.

Scaffolding is perhaps one of architecture's most familiar temporary structures. It accompanies buildings through construction, maintenance, and renovation, only to disappear once its work is complete. Yet its apparent impermanence conceals a different kind of longevity. Scaffolding systems are designed to be assembled, dismantled, transported, and reused, with standardized components robust enough to withstand repeated handling and changing site conditions. Their temporary character lies less in the material itself than in the duration of each assembly.

This logic is not unfamiliar in furniture design. Dieter Rams's 606 Universal Shelving System, designed for Vitsœ in 1960, established a modular approach in which shelves, cabinets, and other components could be rearranged, expanded, or transported as circumstances changed. Similarly, IKEA's modular storage systems popularized and demonstrated how furniture can be understood as a collection of interchangeable parts rather than a singular, finished object. Although different in material and intended lifespan, these systems share an important principle: longevity can be achieved through adaptability rather than permanence of arrangement.

As cities struggle to provide adequate and affordable housing, examining built examples of collective housing can help inform decisions about what to build and how. These projects offer opportunities to assess solutions, understand their limitations, and consider what might be applied elsewhere. In Paris, two recent examples combine apartments of different sizes with access to gardens, courtyards, and other outdoor spaces, working with structures already in place.

In architecture, the word "pavilion" can describe an endless variety of structures. It might be defined as a principle and a typology, a freestanding structure, a temporary intervention, a gathering place in the city, or a space for experimentation. This last quality is what unites the six unbuilt projects featured here, all designed and submitted by ArchDaily readers. Here, the definition lies in their sculptural qualities and formal exploration, while their permanence and location vary according to each structure's purpose. The proposals also demonstrate another quality inherent to the pavilion: the intention to symbolically represent a stance. Their exploration of form and material thus also reflects a search for a sense of boundary, wonder, or a shared future.

About an hour's drive from New York, the Corwin House sits in hilly woodland high above the Saugatuck River. Completed by Richard Neutra in 1956, it is one of only three houses the architect built in Connecticut. Architectural designer Aziz Osko has updated the house, revisiting details from Neutra's original design that were never built.

The commission began when Betty and Henry Corwin asked Neutra whether he could recommend an East Coast architect working in a similar style. Neutra was so taken with the wooded site above the river that he took on the commission himself.

Brick and wood can establish a dialogue between architectural permanence and the textures of coastal environments. In Höllviken, on the southern coast of Sweden, Seaside House by Koistinen Hellborg Architects explores how materiality, light, and spatial organization can shape a home in relationship with its natural surroundings. Located among sandy terrain, heathland, moss, and pine trees, and within walking distance of the sea, the house responds to a landscape defined by subtle color variations, seasonal changes, and a strong connection to the outdoors.

In Uruguay, small-scale residential projects increasingly occupy rural and coastal landscapes, from the hills of Villa Serrana to the maritime forests along the Atlantic coast. Building in these areas often requires structural materials that balance durability, thermal efficiency, and transport feasibility. In these environments, projects rely heavily on materials such as engineered timber framing, steel structural members, exterior wood cladding, or offsite fabrication. These design choices not only help to reduce the weight of raw materials that must be transported over unpaved access roads, but also make construction more feasible in remote locations. The context of the projects in this collection also seems to have played a limiting role regarding floor areas, which were kept at 60 m² or less to reduce structural material requirements and the impact on the terrain.

Wellbeing is no longer confined to exclusive resorts, spas, or hospitality settings. Today, it has become an essential part of contemporary living, inspiring homeowners to create private spaces dedicated to relaxation and personal care. Collections such as LEMI's Home Spa Collection explore this growing interest in residential wellness through a selection of massage beds and relaxation loungers.

"Antarctica is known through narratives," states Victoria Nuviala Antelo during the lecture on Inhabiting the Extreme: An Architectural Biography of Antarctica, presented at the Buenos Aires International Architecture Biennial. Indeed, throughout architectural history, numerous stories, experiences, ways of inhabiting, and building practices have often been excluded from official narratives. Buried beneath thick layers of ice, the history of Antarctic architecture tells a story of impermanence. The ice surrounding the continent expands and contracts each year, doubling its surface area, while the species that inhabit it migrate and return according to their life cycles. Ice covers structures as katabatic winds erase the traces of more than 200 years of human presence. Explorations, settlements, architectural interventions, and ways of inhabiting remain concealed within one of the most extreme landscapes on the planet.

From November 17 to 19, 2026, interihotel MAD26 will bring together architects, interior designers, hospitality operators, and specialized brands at IFEMA Madrid. Organized by AMBIT Living Spaces Cluster, the event is expected to welcome more than 14,000 professionals, 350 exhibiting brands, and over 200 international speakers. Under the theme Creative Rebellion, it will combine talks, workshops, five specialized forums, and full-scale experimental spaces to explore new approaches to hotel and restaurant design.

After a seven-year pause, Amman Design Week returned to Jordan with a premise that feels closely tied to the city itself: that nothing is ever entirely new. Under the theme "Accumulations," the fourth edition of the biennial event brought together more than 220 designers, makers, architects, and collectives across exhibitions, public interventions, talks, workshops, and performances from October 2 to 17. The premise was particularly relevant to Amman, a city whose architecture has been shaped by waves of construction, migration, adaptation, and reuse, where accumulation is not simply a metaphor.

When London's main drainage was completed north of the Thames in 1868, the Metropolitan Board of Works marked the occasion with a banquet held inside a sewage pumping station. Abbey Mills had been built over the previous three years by the engineer Joseph Bazalgette, working with the architect Charles Driver, laid out on a cruciform plan with eight beam engines, two on each arm. Its style has been read as Byzantine, Italian Medieval, Russian, Ruskinian Gothic and Moorish, and its twin ventilation chimneys, richly ornamented, rose more than sixty meters. The builder called it an elegant structure in a swamp and thought it might pass for a mosque or a temple.

Almost everything else Bazalgette built was buried, and the exception did not last the century. Steam gave way to electric motors at Abbey Mills in 1933, and the chimneys, redundant since then, were demolished in 1941 out of fear that a bomb strike would topple them onto the station. Sanitary engineering consolidated around criteria that could be measured, among them throughput, discharge quality and hydraulic gradient, and appearance registered in none of them. Treatment moved outward to floodplains, estuaries and municipal edges where land was cheap, and gravity did useful work.
