How can we construct buildings using less water? The construction process consumes a vast amount of water resources, and it is time to consider how to reduce this environmental impact.

Can we construct buildings using less water? Throughout June, ArchDaily opened the debate on water resources in architecture, inviting our readers to join the discussion.

Global water use data is discouraging, and the construction process accounts for a significant portion of this consumption. It was time to think about how to reduce this impact. The need to design buildings that do not require water offered a unique opportunity to explore innovative and sustainable alternatives to minimize or even completely eliminate water use in construction.

Most people rarely remember a passage. They remember the classroom, the apartment, the gallery, or the plaza at the end of it. Passages are usually designed to disappear into the background, guiding movement from one destination to the next. Yet some of architecture's most memorable experiences happen while moving through a place rather than arriving at it.

Circulation is often treated as one of architecture's most practical elements. Corridors connect rooms, galleries provide access, and walkways organize movement through a building. Their purpose seems straightforward: to help people get from one point to another. Because of this, circulation spaces have long been considered secondary to the programs they serve. Attention tends to focus on destinations, while the spaces in between remain largely unnoticed.

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.

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.

The home carries multiple identities as shelter, sanctuary, workplace, and stage for daily rituals. In recent years, its role has expanded in unprecedented ways. The pandemic, notably, coerced the home to act as a site of extraordinary adaptability to absorb functions once delegated to schools, offices, gyms, and studios. This transformation has shifted how we imagine domestic life, urging us to think of the home not simply as a backdrop for activity but as a dynamic framework for living, producing, and creating. Within this expanded understanding, artists find themselves asking a renewed question: how can the home allow the flexibility needed for creative practice?

Quarries can be seen as indelible abandoned scars of human resource extraction. Man-made spaces, perceived as voids, and material gain, have fundamentally shaped our accelerating built environment. All the while, the earth stands still as a silent witness. For decades, these open-pit mines have been viewed as a necessary consequence of consumerism and urban growth, their raw, imposing forms a testament to the large-scale extraction of materials essential for building our cities. However, a global architectural movement is now emerging to engage with these existing forms, transforming these subtractive spaces into sites of innovation, collaboration, and renewed purpose.

Blending vernacular techniques with contemporary experimentation, Mexico's architectural landscape is shaped by a continuous dialogue between tradition, materiality, and modernity. As the fifth most biodiverse country in the world, Mexican architecture seeks to respond to its vast range of natural environments, climates, and cultural traditions, all within a territory marked by striking contrasts. Reflecting a visible duality, it can embody both exclusivity and act as a catalyst for social transformation.

Around the world, a passionate community of bird watchers, from novice observers to seasoned ornithologists, is drawn to the subtle movements, distinct calls, and remarkable migrations of birds. This global fascination has led to the creation of thoughtfully designed spaces by architects and designers, enhancing the bird-watching experience while respecting the ecological landscapes in which they are placed.
