The term vault in architecture refers to a self-supporting arched structure that forms a ceiling or roof, which can effectively create a wide, column-free space. While traditional masonry vaults transfer loads to walls and buttresses, contemporary versions are more broadly defined as any ceiling that follows the roofline, creating a high, curved interior. These modern ceilings are typically framed using materials like concrete, timber, or steel, which provide the structural flexibility to create the dramatic effect of a vault without its historical constraints. The round arch vault, in particular, seems to have been a recently favored form for its simple, elegant geometry and its ability to adapt to a variety of modern residential styles.
In contemporary Japanese and Chinese kindergarten design, architects are transforming the interior spaces from a simple container into an active, multi-sensory environment. This shift seems to follow Studies in developmental psychology that suggest that a child's experience of space begins with a sensorimotor engagement through touch and manipulation. Thus, they place a strong emphasis on the use of materials and the approach of learning through play. Architects seem to be moving beyond traditional classrooms, into environments that are tactile, stimulating, and rooted in their specific contexts. The buildings themselves become tools for education, encouraging children to learn and explore through direct physical engagement.
Whether for design competitions or architectural awards, buildings are often judged for what they offer–the programmed functions, the form, or the visual delight. In a minority of cases, it is the absence or the reduction of intervention that made a project successful. In 1971, a high-profile architectural competition in Paris was won by a proposal that only utilized half the available site, giving the rest as an urban space to the city. In London, a proposal to convert a disused power station with minimal additions, leaving large spaces untouched, won a design competition in 1994. The Stirling Prize, the UK's most prestigious architectural award, in 2017 was won by a proposal that was little more than an empty platform. These examples of cultural buildings from Northwestern Europe illustrate how the absence of intervention can provide more.

In a time when much global architecture can feel disconnected from local identity, the work of Rafayel Israelyan stands out for being rooted in place, culture, and memory. Working in mid-20th-century Armenia, Israelyan created architecture that is more than functional or monumental; it is culturally resilient. His use of traditional Armenian motifs, materials, and symbolic forms gave his designs a second life after the fall of the Soviet Union, when many buildings across post-Soviet states were abandoned or demolished. Armenia, by contrast, preserved many of his works, likely because their design approach not only served a specific moment in time, but also told a larger story. Long before concepts like sustainability or critical regionalism became popular, Israelyan understood that buildings gain meaning and endurance when they reflect the specific identity and characteristics of their place.
Red clay roof tiles appear in many architectural traditions around the world, despite the cultures being geographically or historically distant. However, this isn't necessarily surprising. Clay is an abundant and accessible building material worldwide, with some studies and other sources suggesting it comprises approximately 10-13% of the Earth's soils. Red tiles, in particular, are often a product of the local soil's mineral content and the firing process. Their widespread use across unrelated regions is less about shared cultural influence and more about material logic: clay is cheap, durable, and easy to work with using simple tools and techniques. In Vietnam, for example, there is a unique and visible tradition of clay tile use that dates back centuries. Regions like Vinh Long, nicknamed the "kingdom of red ceramics", have an abundance of this material, supporting a long history of tile-making. In some parts of Vietnam, these tiles are known as Yin-Yang tiles, due to the concave and convex shape in which they are formed during production.
Vernacular architecture often utilizes locally sourced materials and construction practices honed over centuries. This approach raises questions about its potential relevance for contemporary design challenges. The prevalence of high-rise developments globally, often relying on sealed envelopes and mechanical climate control, contrasts with historical architectural practices. Traditionally, regional architectures emerged from local communities, fostering distinct cultural identities and integrating passive systems for ventilation, cooling, and heating, often utilizing natural elements. The Hanok, traditional Korean houses, serve as a case study. Beyond their current role in tourism, they are also an example of how vernacular knowledge can provide passive climate-response strategies that align with the current principles of creating environmentally friendly buildings.
Scandinavian design has long been admired for its minimalist aesthetic and functionality, which places value in the simple things, deeply rooted in the concept of Hygge. This reverence goes beyond interior design and extends also to the natural world, resulting in high-quality architecture and landscape installation design that enhances human connection to untouched environments. Rather than imposing grand structures upon the environment, the Scandinavian approach is one of subtle and precise intervention. These projects are not meant to dominate but to enter into a dialogue with the existing landscape, using thoughtful design to potentiate its inherent shape, color, and texture. The goal is to complement and enhance, creating spaces that serve a functional purpose while simultaneously deepening the visitor's connection to their surroundings.

The Canada Pavilion at the 19th International Architecture Exhibition – La Biennale di Venezia, hosted Picoplanktonics. A research that emerged as a radical rethinking of how architecture can become a platform that blends biology, computation, and fabrication to propose an alternative future, one where buildings don't just minimize harm, but actively participate in planetary repair. At its core lies a humble organism: marine cyanobacteria, capable of both capturing carbon and contributing to the material growth of the structure it inhabits. The project has been developed over 5 years by a group of researchers at ETH Zurich, led by Andrea Shin Ling and a group of interdisciplinary contributors and collaborators. Together, they formed the Living Room Collective, founded a year ago to build upon this work and showcase it at the Venice Biennale. The Core team members include Nicholas Hoban, Vincent Hui, and Clayton Lee. This conversation with the team behind the project shares the philosophy, technical challenges, and speculative horizons that animated their work from printing living sand lattices to maintaining microbial life in a public exhibition. Their aim is to inspire people to reconsider architecture not as a static object, but as a living, evolving process. One that requires care, patience, and a radical shift in mindset.
When examining photos of Japanese houses, one frequently notices a recurring space with tatami mats, often slightly elevated and integrated into the public areas of the home. This is the washitsu, or Japanese-style room: a traditional, multipurpose space still commonly found in modern residential architecture. Used for activities ranging from reading and sleeping to hosting a family altar, its versatility is central to its continued relevance. This article explores the Washitsu's layout and meaning, beginning with its historical origins to better understand its role and interpretation in contemporary Japanese homes.

Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.
In most situations, architects navigate a complex web of construction codes, airspace regulations, and numerous other rules that dictate the form and execution of a project. However, cultural architecture often presents a unique opportunity for more daring and expressive designs. These projects frequently garner support from local governments, unlocking possibilities for formal explorations that might otherwise remain unrealized. In this regard, cultural architecture serves a dual purpose: enriching the community and establishing iconic landmarks that define the identity of their city or region. This ambition has certainly manifested in Taiwan. Situated in the heart of East Asia, this island nation boasts a remarkable array of formal explorations by both international and Taiwanese architects.
The internal environment is the focus of this second article about designing for noise to improve well-being. According to several recent studies, noise in cities has become an increasing hazard to health. Environmental noise, that is, noise from traffic, industrial activities, or amplified music, which reaches internal spaces, is not merely an annoyance. It has been linked to cardiovascular disease, diabetes, dementia, and mental health issues. As the world urbanizes, more people are exposed to excessive levels of noise. In medium- and high-density housing, in office buildings, and in schools, noise pollution can emanate from internal as well as external sources.
Once seen as purely utilitarian, bare concrete blocks have increasingly become part of an architectural transformation. In regions where warm climates make insulation unnecessary, this material can be left exposed, free of cladding, finishes, or embellishment. In doing so, texture, bond, and form can define the building's character and simplify construction while creating new opportunities for expression and identity. This also creates a platform to explore the concept of material honesty. Beyond its aesthetic value, using a material "as is" can significantly reduce construction costs and minimize maintenance during the building's lifespan.
When thinking about Japan, the first thing that comes to mind is the bustling streets of Tokyo, old fortified castles, and the cherry blossom-lined rivers in the urban areas. However, little is discussed regarding a real estate market problem currently ongoing in the country: Akiya, a Japanese term that translates to an empty house. In 2024, the number of Akiya in Japan went up to a record high of nine million units. Some believe that at the root of the issue is depopulation. When homes are passed down through family inheritance, they frequently become burdens rather than assets. As younger generations increasingly move to cities or live in apartments, they usually have no interest in living in or maintaining the old family home, especially if it's located in a less convenient or rural area. Cities like Tokyo see a smaller number of Akiya due to the elevated price of the land. Nonetheless, issues such as elevated costs of adapting the house to the new earthquake regulations and higher taxation on vacant land, still cause people to abandon them even in urban areas.

With modern medicine, it may be difficult for many people today to imagine the devastation caused by Tuberculosis (TB) just about 100 years ago. Initially associated with insalubrious, overcrowded conditions, just in Canada it caused the death of approximately 8000 people annually in the late 19th century. During this time, before more advanced treatments were discovered, prescriptions from doctors involved sunlight, fresh air, and rest. As a response, sanatoria were established. These were places where patients could be separated from the community to manage their disease. One testament to that legacy stands in the heart of Montreal: the former Royal Edward Laurentian Institute, later known as the Montreal Chest Institute. Born from crisis, it has since become a symbol of resilience, transformation, and innovation, shifting from a space of isolation to a thriving hub for research and entrepreneurship in the life sciences.
When we think about cities, we often assume the orthogonal grid is the norm: neat, predictable, and rational. However, many urban areas around the world, notably those shaped by hills and uneven terrain, defy this convention. In cities like Lisbon, in Portugal orthogonal grids appear only in flatter zones such as Baixa, while surrounding areas like Alfama adapt organically to topography. These areas create more layered, irregular, and visually dynamic urban forms. Yerevan in Armenia, offers another urban example of this adaptation: the Cascade Complex transforms a steep hill into a terraced public space that connects different city levels while framing panoramic views. For other countries, this response to topography becomes even more critical. Cities like Tegucigalpa in Honduras or Valparaiso in Chile are defined by steep, irregular terrain that requires architects to engage deeply with the land. Designing in these contexts, especially for residential projects, demands technical adaptation and a contextual understanding that allows the slope to become a generative element in the design process.
For nearly the past two decades, cities around the world embraced "starchitecture"—futuristic, eye-catching buildings designed by globally renowned architects. In China, this trend was particularly pronounced as rapid urbanization fueled the construction of iconic megastructures like Zaha Hadid's Galaxy SOHO, OMA's CCTV Headquarters, and Herzog & de Meuron's Bird's Nest Stadium in Beijing. At the time of their construction, these were all celebrated as symbols of progress and global ambition. However, architecture worldwide has begun shifting toward a more context-driven, human-centered approach, with China emerging as one of the key contributors to this transformation. This year, Liu Jia Kun's 2025 Pritzker Prize further underscores that shift.
