Architecture is traditionally chronicled through the persistence of the solid. We define the discipline by the weight of the lintel, the mass of the pier, and the resistance of the wall. Even when lightness is invoked, it is usually understood as a subtractive act, the thinning of a section or the precarious reduction of a load. Yet there is a parallel history, less visible and harder to isolate, in which the primary material of construction is not what occupies space, but what moves through it.

To treat air as a medium is to move past the binary of the envelope. The boundary between the interior and the world ceases to be a line of absolute separation and becomes, instead, a site of filtration and pressure. We begin to see the building as a thermal valve, a series of gradients where moisture, velocity, and heat are not merely background "conditions" to be mitigated by mechanical systems, but are the very substances being shaped.

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.

Observed annually on April 22, International Mother Earth Day frames this week's architectural discourse through an urgent call to rethink the relationship between the built environment and natural systems, foregrounding themes such as urban rewilding, the restoration of aquatic ecosystems, and the integration of ancestral knowledge into contemporary design practices. On another note, the opening of Salone del Mobile.Milano 2026 and Milan Design Week 2026 seek to reinforce the global relevance of design as a platform for exchange and experimentation, activating the city of Milan through a network of exhibitions and installations that engage both industry and public audiences. Among the announcements of award-winning architectural projects this week, the United Nations' House of No Waste (HØW) Competition highlights emerging architectural responses to climate and resource challenges. The awarded projects demonstrate scalable strategies for reducing material waste and embodied carbon while promoting adaptable, socially responsive, and resource-conscious public infrastructure.

Using massive s plates, often several centimeters thick and weighing tons, Richard Serra's sculptures convey an almost improbable sense of lightness. This effect does not result from a reduction of mass, but from how that mass is organized: large curved surfaces tilt, narrow passages compress the body, and seemingly unstable elements create a constant sense of imbalance. Serra transforms weight into a dynamic spatial experience.

In architecture, lightness has occupied a central role at least since the modern period. While earlier traditions, such as Greek and Roman architecture, were closely associated with stability, and large churches with monumentality, the twentieth century introduced a decisive shift in how matter is handled, particularly through the separation of structure and enclosure.

On Sunday, April 19, 2026, the Los Angeles County Museum of Art (LACMA) opened its new David Geffen Galleries to the public. Designed by architect Peter Zumthor, the building offers an elevated exhibition space for the museum's permanent collection. All artworks are presented in a single-level open space, in a non-hierarchical layout of cultures, traditions, and eras, spanning 6,000 years of art history across approximately 155,000 objects. The space is flexible, accommodating diverse curatorial projects as well as visitors' individual paths. The project marks a new step in the institution's two-decade transformation into a global art museum and the most comprehensive in the western United States.

What do lightweight materials bring to public space with an ethical, ecological, and non-extractive design principle? Various textile textures offer a point of entry, being closer to the body than heavy conventional structural materials. Through its flexibility and responsiveness, it enables a form of soft enclosure rather than a fixed boundary in architectural space. Responding to minimal environmental stimuli, the fabric brings continuous movements into space. When layered or assembled, it produces gradations of density, depth, and enclosure, while recent innovative fabrication technologies extend the possibilities of its form and structural durability.

Semi-transparent materials further mediate the conditions of visual permeability and bodily experience of the space. By transmitting and filtering light, they blur clear separations between interior and exterior, solid and void, creating thresholds that are neither fully open nor fully enclosed, but constantly in negotiation. Reinterpreting structure in urban space through lightweight, translucency, and softness opens up alternative modes of spatial perception and bodily engagement.

Between June 23 and August 30, 1988, The Museum of Modern Art (MoMA) in New York held an exhibition titled Deconstructivist Architecture, as part of a program "conceived to examine current developments in architecture." Curated by Philip Johnson and Mark Wigley, it focused on the contemporary work of seven international architects: Coop Himmelblau, Peter Eisenman, Frank Gehry, Rem Koolhaas, Daniel Libeskind, Bernard Tschumi, and a young Zaha M. Hadid. At 37 years old, her work was presented to the world as an example of "the emergence of a new sensibility in architecture." The material on display was not a model or a blueprint, but a painting, The Peak, submitted for an architectural competition in Hong Kong in 1983. From this starting point, her contribution to architecture deepened along the same lines recognized at the time of her inclusion in the exhibition: the development of a distinctive, mathematical, and, in her own words, "fluid" architectural language, and her emergence as a leading female figure in a field historically dominated by men.

In 2023, ArchDaily's editor-in-chief sat down with Tarek Qaddumi, Executive Director of the Line Design at NEOM, at the closing of the Line Exhibition in Riyadh. Qaddumi described a layered, three-dimensional city organized around the idea of a "five-minute sphere" of access: walkable communities stacked vertically, connected by high-speed rail, freed from cars and conventional street infrastructure, and designed to coexist symbiotically with the surrounding natural landscape. It was a compelling vision, and in the context of the moment, it was simultaneously credible and appealing. For architects and urban thinkers grappling with the failures of twentieth-century city-building, the ideas articulated were worth engaging and planning.

Chilean architect Smiljan Radić Clarke has developed a body of work that resists easy categorization. His buildings often seem both ancient and provisional, carrying a monumental presence while retaining an unexpected sense of fragility. Stone, concrete, timber, fabric, and fiberglass are combined in unexpected ways, producing architectures that hover between permanence and ephemerality. Rather than pursuing a stable formal language, the 2026 Pritzker laureate approaches architecture as an open field of experimentation, where material behavior and structural perception are constantly tested.

Buildings were always intended to solve a straightforward problem: shelter. Through form and material, they protected occupants from the weather and organized human activity. Modern architecture, along with evolving lifestyles, added new priorities — efficiency, density, structural innovation, and aesthetics. People now demand more from buildings. Occupants increasingly want environments that actively support how they live, work, and feel.

Wellness has become a central concern in modern times. Decades of research in environmental psychology and building science reveal that indoor conditions can profoundly affect human health and behavior. Lighting influences circadian rhythms and sleep patterns. Air quality impacts cognitive performance and respiratory health. Temperature and acoustics shape comfort and concentration.

Today's housing crisis is a global phenomenon that can be broadly divided into two major problems: a shortage of residential buildings and barriers to accessing those that already exist. The deficit is real and concrete when it comes to what the UN calls "adequate housing for all." According to UN-Habitat, an estimated 96,000 new housing units would need to be built per day to meet population needs by 2030. Climate change and forced migration are broadening the gap. But 2.8 billion people worldwide, representing nearly 40% of the global population, lack access to stable shelter, secure land, and basic sanitation services not only because of underproduction, but also due to an economic barrier: an affordability crisis. As demand grows and prices rise, housing, now increasingly functioning as a form of social security, becomes a target for rental income and real estate speculation. As adequate housing is a human right, pressure on governments and private entities is increasing worldwide to limit speculation and ensure fair access to existing dwellings. Below, we present four examples of initiatives in Spain, Australia, France, and the United States that aim to urgently expand housing access while limiting speculation.

The 2026 Pritzker Price Award has been awarded this year to the Chilean architect of Croatian descent, Smiljan Radić Clarke. Born in Santiago, Chile, in 1965, his practice evokes a geography of extremes, shaped by the tectonic tension between the staggering weight of the Andes and the seismic instability of the territory. After graduating from the Pontifical Catholic University of Chile and pursuing further studies in aesthetics in Venice, Smiljan Radić Clarke established his base in Santiago. From there, he has developed one of the most singular visions in contemporary architecture. His work privileges the intensity of the moment through a fragile architecture. Within it, the building operates as a temporary and tactile refuge that places the spectator in a state of aesthetic uncertainty, oscillating between ancestral ruin and avant-garde artefact.

Heritage sites constitute complex spatial archives in which architecture, history, and collective memory converge. They encompass a wide spectrum of contexts—from archaeological remains, ancient and historic townscapes, UNESCO-listed landscapes, to early modern civic structures and industrial infrastructures. Yet these environments confront challenges: climate change, urban transformation, disaster, shifting social needs, and the gradual erosion of material fabric. Revitalization and restoration projects respond to these conditions by positioning architectural and spatial practice as an active mediator between preservation and the contemporary topologies.

In current practice, conservation is understood as a creative process of adaptation and reinterpretation that serves both communities and inhabitants. At the same time, monumental architecture continues to define the identity and landscape of a place for wider audiences and future generations. Architects and planners are called upon to negotiate sensitive historic contexts while introducing new programs, techniques, and spatial experiences. They exemplify diverse design approaches, including precise structural interventions, climate-responsive strategies, and meticulous material restoration, alongside the thoughtful insertion of new architectural elements. Equally important is their engagement with vernacular knowledge and materiality, which preserves the locality and cultural specificity of each site.

Cities around the world share a common goal: to become healthier and greener, supported by civic infrastructure that restores ecosystems and strengthens public life. The question is how to reach this. Global climate targets, local building codes, and municipal standards increasingly guide designers and planners toward better choices. Still, many cities struggle to translate these frameworks into everyday, street-level comfort and long-term ecological protection. What happens if the city is no longer treated as a traditional city, but as a national park?

National parks operate through systems of protection that treat land as a network of ecological relationships rather than a collection of isolated sites. They establish a shared baseline for what must be preserved, maintained, and made accessible over time. When this logic is applied to the urban environment, success can inspire pride and a sense of shared responsibility among designers, policymakers, and residents, fostering a collective commitment to health, habitat, and civic infrastructure.
