When designing a space—whether at the scale of interiors, architecture, or infrastructure—materiality is a central concern. Beyond aesthetics, materials determine how a project functions, ages, and endures. Some architects—such as Wang Shu and Kengo Kuma—have built their practices on a deep sensitivity to the potential and limits of materials. But even in the most pragmatic sense, the question arises: What lasts? What doesn't? And how do materials change over time? Naturally, materials shape atmosphere and appearance—qualities that often matter most to clients. Yet increasingly, the discourse around materiality has shifted from structural substance to surface treatment. When did we start focusing more on "decorating" our spaces by layering one material over another, rather than relying on the inherent beauty and performance of the building fabric itself?
The 2025 Osaka Expo has captured widespread attention—not only for its architectural ambition and spectacle, but also for breaking records and generating controversy. Its most iconic feature, a monumental timber ring designed by Sou Fujimoto, has already made headlines as a Guinness World Record-breaking wooden structure. Built on the reclaimed island of Yumeshima, the site has attracted praise and critique in equal measure. Beyond its awe-inspiring 2-kilometer circumference—parts of which extend dramatically over the water—the structure has also drawn concerns, including questions about health & safety, extreme heat, and swarms of insects that may affect the visitor experience.
This year also marks a significant anniversary: the 55th year since the 1970 Osaka Expo, held under drastically different socio-economic conditions. Comparing these two expos—both hosted in the same city—offers a rare opportunity to reflect on how the rhetoric, curatorial themes, and architectural ambitions of world expos have evolved over time. From "Progress and Harmony for Mankind" in 1970 to "Designing Future Society for Our Lives" in 2025, the shift in thematic focus reveals changing global priorities. Meanwhile, the scale and nature of architectural involvement have also transformed, from the futuristic visions of Japanese Metabolism to a more internationally dispersed group of designers concerned with sustainability, technology, and civic engagement.
The Mid-Century Modernist movement was more than an aesthetic or material shift in the United States, as it was a response to a rapidly changing world. Emerging after World War II, this architectural revolution rejected ornate, traditional styles of the past in favor of clean lines, functional design, and incorporation of flashy materials like steel, glass, and concrete. Modernism was a break from tradition, focusing instead on simplicity, efficiency, and a vision for the future. It reflected the optimism of a nation rebuilding itself, where technology and innovation shaped everything from cityscapes to suburban homes.
In March 2025, the actor Adrian Brody rose to the stage to collect his Academy Award for playing the role of László Toth in the acclaimed film, The Brutalist. The film is about a Bauhaus-educated architect who escaped Nazi Germany in the 1930s for the United States. Whilst the story is fictional, it reflects the lives of several émigré architects who left Central Europe in search of better working and intellectual conditions. These included the first three directors of Bauhaus, the renowned German school of design established in 1919. The first and third directors of the school, Walter Gropius and Mies van der Rohe respectively, ended up in the US where their careers in teaching and building both flourished. Lesser known is the second director, Hannes Meyer, who took a different path from his colleagues.
Modernism, a movement that sought to break away from traditional forms and embrace the future, laid the groundwork for many technological and digital advancements in contemporary architecture. As the Industrial Revolution brought about mass production, new materials, and technological innovation, architects like Le Corbusier, Walter Gropius, and Mies van der Rohe championed the ethos of "form follows function" and a rational approach to design. Their principles resonate in the digital age, where computational design and high-tech materials redefine form and construction.
The 20th century's modernist ideals — efficiency, simplicity, and functionality — created a foundation for architects to experiment with structural clarity and material honesty. High-tech architecture, which emerged in the late 20th century, evolved from these principles, merging modernism's clean lines with advanced engineering and technology. This paved the way for parametricism and algorithm-driven design processes, revolutionizing architecture and enabling complex forms previously thought impossible.
When discussing modernist living, several iconic private residential projects may first come to mind—Le Corbusier's Villa Savoye, the Case Study Houses, most notably by Richard Neutra, Pierre Koenig, and Charles and Ray Eames, as well as the glass houses by Mies van der Rohe and Philip Johnson. Most of these projects exemplified an idealized vision of modern living, set in picturesque landscapes and characterized by experimentation with new construction methods, materials, and spatial concepts. Their designs embraced openness, blurring the boundaries between private and public spaces, largely unburdened by constraints such as density, efficiency, accessibility, public transit integration, or communal considerations.
While these modern homes remain influential in contemporary residential design, they also—perhaps unexpectedly—laid the groundwork for high-density housing principles. Concepts such as the interplay between public and private space, modular construction, and prefabrication, initially explored in these private residences, have been adapted to the vastly different constraints of social housing.
Modernism emerged in the early 20th century as a revolutionary movement that rejected historical styles, prioritizing functionality, innovation, and rationality. Grounded in the promise of industrial progress, architects like Walter Gropius, Le Corbusier, and Ludwig Mies van der Rohe championed using new materials and construction methods, striving for a universal architectural language. Their work introduced radical ideas: open floor plans, expansive glazing for natural light, and pilotis that elevated structures, symbolizing a new architectural era. However, alongside its groundbreaking ideas, modernism's relationship with sustainability has sparked ongoing debates.
While modernist architects sought to address social and economic challenges through affordable housing and efficient design, their reliance on energy-intensive materials like concrete and steel created unintended environmental consequences. The large-scale industrialization celebrated by modernists often disregarded local climates and ecological systems, leading to inefficiencies. Yet, the principles of functionality and adaptability embedded in modernist architecture laid the groundwork for what we now recognize as sustainable practices. From Le Corbusier's rooftop gardens to Frank Lloyd Wright's integration of nature, the seeds of environmentally conscious design were undeniably present, albeit limited in their execution.
Upper Lawn's thoughtful interplay between the new and the existing is particularly compelling. Built on the remains of an 18th-century English farmhouse, the pavilion repurposes thick masonry walls from the original structure, incorporating elements such as the well, trees, and lawn into its design. Using prefabricated materials like timber, glass, and aluminum, the Smithsons constructed a light-filled space that harmonizes with its surroundings, embodying their principle of "as found architecture" — a concept rooted in honoring and adapting to preexisting conditions rather than imposing on them.
Much of the production of modern architecture on the American continent was based on the model of European architects who, with their works, projected the fundamental premises and ideas for modern living. These pillars of architecture were transferred and consequently adapted to the American territory, introducing, at the same time, their own characteristics according to the territorial, socio-cultural and economic context.
We understand that good architecture is that which serves as a model for solving problems inherent to the discipline of architecture in general. This is why certain references that we consider today as "classics" are examples of good architectural practices that have been appropriated by other architects, taking the pertinent and necessary elements to achieve a result in accordance with the particular context.
Bauhaus's designs have influenced our contemporary society in obvious and subtle ways. Iconic examples include Marcel Breuer’s Wassily Chair, the B55 Chair, the Bauhaus typeface, and the graphic design principles emphasizing clean lines, primary colors, and geometric shapes. However, the architectural construction details of the Bauhaus movement are much less discussed. While most can readily identify modern or Bauhaus buildings by their geometric forms, functionality, and industrial materials, their architectural details are often overlooked. They not only echo the design language of Breuer’s renowned furniture pieces but also have influenced the much-celebrated architectural glass details of Mies van der Rohe. How were Bauhaus's details executed, and how might they be translated into contemporary details today?
Beyond serving as mere backdrops for fashion shows, architecture often influences fashion collections, contributing spatially to their storytelling, offering material inspiration, and showcasing the connection between structure and shape. As both disciplines revolve around form, structure, and the human experience, architecture, and fashion share a strong connection, one often explored by creators in both fields. From meticulous tailoring and structural designs that mimic architectural lines, contours, and volumes, to architecture taking cues from how fashion works with the human shape, this interplay can create multidimensional experiences for the enthusiasts of both high fashion and architecture.

The rights to reconstructKisho Kurokawa's iconic Nakagin Capsule Tower are currently sold on one of the largest NFT sites. While the tower’s demolition has begun earlier this year, the auction sells the right to rebuild the structure, in both the metaverse and in real space. The idea of recreating the Metabolic building in a virtual space seems natural. It could allow a larger community to explore an iconic piece of architecture and encourage them to experiment with it, an initiative in line with Metabolist ideals. On the other hand, the idea of reconstructing a demolished historical building in the physical world raises a different set of conflicting emotions. Architectural replicas are not the norm, but their existence raises questions regarding the identity and authenticity of works of architecture.

The German Pavilion was designed by Ludwig Mies van der Rohe in 1929 for the German representation at the International Exhibition in Barcelona held on Montjuic that same year. The Pavilion was conceived as a space of modest dimensions and refined materials. It was made of glass, steel, and four types of marble, intended to host the official reception led by King Alfonso XIII and German authorities. The uniqueness in the use of materials, which was always highlighted in his work, wasn't about their novelty but about the modernity they represented and their precise application in terms of geometry, the accuracy of their components, and the clarity of their assembly.
From September 14th to October 8th, 2023, "Psicoarquitectura" will be showcased at the German Pavilion, designed by Mies Van der Rohe and Lilly Reich, located in the city of Barcelona. The Mies van der Rohe Foundation, in collaboration with LAB 36 and Senda Gallery, is hosting this temporary artistic intervention by the artist and architect Oscar Abraham Pabón. This intervention explores the materiality of this iconic work of the Modern Movement, delving into its interpretative and psychological dimensions.
Whether rain or shine, Toronto is a yearlong bustling city, the largest in Canada and the fourth largest in North America. It’s become a cosmopolitan center with its renowned business district and cultural venues/ events that come alive during the summer and early fall nights. Toronto suggests a beautifully diverse urban setting between shimmering high rises and smaller brick houses, intertwining residential and vibrant commercial areas, public parks, and even beaches. All become part of the city's striking skyline, crowned by the iconic CN tower.
Toronto’s ongoing sprawl and constant urban development are noticeable as new projects spread through the city, weaving themselves into the existing buildings, from 19th-century landmarks such as the Gooderham Building to modern and contemporary major works like the Aga Khan Museum. These new constructions include increasing adaptive reuse and retrofitted projects throughout the city as more efforts and incentives are provided to reduce carbon emissions.
