On Earth Day 2025, observed annually on April 22, we are once again reminded of the urgent environmental and sustainability challenges that face our planet—challenges that continue to evolve alongside global economic, political, and cultural shifts. The building and construction industry remains one of the most critical sectors in the effort to manage and reduce global carbon emissions. This year, these issues are being addressed through increasingly diverse lenses, calling for more holistic and integrated approaches. It's vital that we view sustainability not as a one-size-fits-all solution, but as a multi-scalar effort—one that spans from large-scale urban development and strategic planning, to the advancement of sustainable materials, and even to temporary, thought-provoking interventions like exhibitions and installations. In doing so, we reaffirm our commitment to reducing our collective carbon footprint, while shaping a built environment that promotes human well-being and planetary health.
The bamboo scaffolding building typology—temporary, agile, and deeply rooted in tradition—particularly, the bamboo shed theatre building technique, is recognized as an item of Intangible Cultural Heritage in Hong Kong. As one walks through the city, especially in busy urban districts, it's nearly impossible not to encounter a bamboo scaffold within a five-minute radius. Bamboo scaffolding is arguably the most iconic construction material in Hong Kong, valued for its abundance, sustainability, flexibility, adaptability, and—most importantly—scalability. These qualities have contributed to its widespread use in temporary construction, from building maintenance and renovations to festival stages and sporting events.
However, this once-ubiquitous feature of the urban landscape may be slowly fading from view. A dwindling pool of skilled, younger workers—combined with evolving construction regulations—has contributed to its decline. On March 17, the Development Bureau announced plans to "drive a wider adoption of metal scaffolds in public building works." In practice, this means the Architectural Services Department (ArchSD) will soon require at least 50% of its capital works projects to utilize metal scaffolding. While not a formal ban, the policy signals what many see as the beginning of a gradual phase-out of bamboo scaffolding in public-sector construction.
In contemporary urban development, the concept of Privately Owned Public Space (POPS) has gained increasing prominence. These are spaces that, while built, owned, and maintained by private developers, are legally required to remain publicly accessible. Often the result of negotiated planning incentives—such as zoning bonuses or increased floor area—POPS have become especially prevalent in dense urban environments where land is limited and demand for public amenities is high.
Integrating natural elements into architectural design has long been a fundamental pursuit in creating comfortable, sustainable environments that enhance both individual well-being and the relationship between buildings and their surrounding context. In areas with vast landscapes, incorporating natural elements is essential for seamlessly connecting architecture with its site. Conversely, in dense urban environments dominated by built structures, introducing greenery becomes also increasingly vital, reintroducing nature into the so-called "concrete jungle."
However, beyond conventional landscape features—such as water fountains, green walls, gardens, or courtyards—architects are redefining what it means to build with nature. The focus has shifted toward deeply integrating architecture with its natural surroundings, creating immersive spatial experiences that blur the boundaries between the built and the organic - in a way, "taming" nature. When successfully executed, these designs go beyond fostering well-being or promoting a healthy lifestyle; they evoke a profound sense of tranquility, power, and harmony, transforming the way we perceive and inhabit space.
The choice of door types plays a crucial role in defining the spatial experience and atmosphere of architecture. Beyond material or style, the way a door is detailed—its movement, weight, and method of operation—can drastically influence how a space is perceived and navigated. However, what truly enables the functionality of different door types is the often-overlooked element of door hardware. Even within the same door type, the selection of hinges, tracks, pivots, and handles can significantly affect how users interact with and interpret the space.
Historically, public bathing was a fundamental necessity for hygiene, giving rise to communal bathhouses in regions where private bathrooms were a rarity. In Japan, for instance, sento bathhouses emerged during the early Edo period, serving as essential facilities when most households lacked their own bathing spaces. Similarly, in other parts of the world where plumbing and water management were considered luxuries, shared public baths became vital components of urban life. Over time, these spaces evolved beyond their functional role, becoming venues for socializing, relaxation, and a temporary escape from daily routines.
However, in the modern era, private bathrooms have become ubiquitous in contemporary homes, effectively addressing the hygiene concerns that once made public bathhouses indispensable. With the rise of alternative social spaces—cafés, fitness centers, bars, and jazz lounges—the traditional communal bath no longer serves the same essential function. While some may still appreciate the social aspect of public bathing, the inconvenience of changing clothes and getting wet in front of strangers can deter many from engaging in the experience.
Architecture and its atmospheric qualities have long been a subject of discussion, yet reaching a consensus on the matter remains elusive. This is largely because spatial experience is deeply personal—rooted in emotions, sensory perceptions, and individual preferences that are difficult to articulate in words alone. The way one perceives, feels, and interacts with a space adds another layer of complexity, making it challenging to define and agree upon its atmospheric impact. Nevertheless, architects and designers continuously strive to shape environments that are not only functional and comfortable but also capable of evoking emotions and leaving a lasting impression on their occupants.
Prefabrication is one of the most transformative innovations in architecture and construction, redefining how buildings are designed, manufactured, and assembled. While not a new concept, its application has evolved to offer a broader range of advantages. Traditionally valued for its precision and quality, prefabrication is now equally recognized for its cost and time efficiencies, particularly in leveraging regional differences in labor and production. This shift has fueled its resurgence across high-end, design-driven projects and large-scale, cost-efficient public buildings.
Transit-Oriented Development (TOD) is a comprehensive urban planning strategy aimed at creating dense, walkable, and vibrant neighborhoods centered around public transportation hubs. By seamlessly integrating residential, commercial, and recreational facilities within close proximity to transit nodes, TODs seek to reduce automobile dependency, increase public transit ridership, and stimulate local economic development. Government agencies play a pivotal role in supporting these developments through zoning reforms, easing floor area ratios (FARs), selling air rights, and facilitating public-private partnerships to secure capital for public infrastructure. While TODs have gained global traction, East Asia boasts some of the most successful examples. Conversely, efforts to replicate these models in different contexts—such as New York City—highlight the importance of adapting TOD principles to local conditions, geographical characteristics, and community needs.
Doors are among the most frequently used architectural elements in any occupied building, serving as movable thresholds that negotiate between private and public spaces. They facilitate both connection and separation among co-inhabitants. Yet, despite their fundamental role, doors are often one of the most overlooked design elements, particularly by clients. In discussions with industry professionals on various interior projects, a common consensus emerges—clients typically pay little attention to door types and details as long as the opening direction aligns with their expectations. However, the world of door design is an intricate one, offering a wealth of possibilities in finishes, installation methods, and modes of operation—each of which can significantly shape the spatial experience beyond the simple matter of swing direction.
The choice of door type and detailing can define or redefine a space entirely. Some doors offer superior sound insulation, while others remain open to connect spaces, enhancing spatial fluidity seamlessly. Certain designs require meticulous installation and ongoing maintenance, while others are virtually hassle-free. Moreover, the type of door selected, particularly that of the hinge, influences not only wall construction but also flooring layers and transitions, adding further complexity to the design process.
Co-living in East Asia has been rising since 2020, rapidly expanding while remaining in its early stages. At the same time, it continues to fulfill a significant demand from young professionals working in major cities. A 2020 study by real estate services firm JLL highlighted the growing demand for co-living in China and Singapore, citing key advantages such as affordability compared to private studio apartments and a contemporary urban lifestyle that fosters openness and shared experiences. Much like other industries where ownership is becoming less relevant—such as streaming services for music, films, and television, or mobility solutions like car- and bike-sharing—co-living appeals to a similar demographic that values flexibility and access over long-term commitments.
Unlike co-living initiatives in Spain, which often focus on multigenerational shared spaces, East Asian co-living primarily targets young professionals with dynamic career paths. Often required to relocate every few years, these individuals prioritize convenience and adaptability over investing in a permanent home. For them, committing to a long-term residence may not be practical, making fully furnished, professionally managed co-living spaces with built-in amenities and hygiene services an attractive option. These environments cater to fast-paced urban lifestyles, where networking at professional events often precedes solitary downtime at home.
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.
It has been nearly three weeks since one of California's most devastating wildfires began, triggering an immense effort to combat the blaze and mitigate further damage. As firefighters work to contain the remaining flames, the city braces for its first significant winter rainfall, raising concerns about flooding and landslides that may exacerbate the already extensive destruction.
Amid these challenges, the wildfire has spurred widespread reflection at local and global levels. Discussions have emerged on topics such as the insurance system, firefighting infrastructure, water resources, global warming's role in high-wind fire conditions, and the impact of landscape design, particularly the use of non-native vegetation.
Bathrooms play a significant role in our daily lives, serving multiple functions beyond basic hygiene. Research highlights their importance as relaxation, introspection, and personal wellness spaces. A bathroom's design and comfort can profoundly influence how we begin and end our day, framing our routines with a sense of ease or disruption. When traveling, hotel bathrooms often leave a lasting impression, as a well-designed and thoughtfully executed bathroom can significantly elevate the overall experience of a stay.
Modernism in architecture emerged at the beginning of the twentieth century, fueled by advancements in science and engineering and a deliberate departure from historical styles. It championed a focus on social equity, urban development, efficiency, and functional design, marking a significant shift in architectural philosophy. Originating primarily in Europe and the United States, modernism captivated the global imagination with its innovative redefinition of space and architecture. Its spread to Asia was facilitated by cross-cultural exchanges—East Asian architects who studied under prominent modernists and European architects working in East Asia through international collaborations or colonial-era influences.
As we close the chapter on 2024, a review of ArchDaily's extensive database projects highlights a few standout interior design trends that defined the year. Among these is the use of stainless steel, often paired with concrete and shades of grey, creating interiors with a refined, industrial elegance. This article delves into the increasing prominence of stainless steel as an interior element, exploring its applications, pairings, and growing appeal despite lingering perceptions of its cold, industrial nature.
In Delirious New York, Rem Koolhaas vividly discusses the Downtown Athletic Club, a striking example of how an unassuming building exterior can conceal a vibrant mix of distinct, self-contained programs. Inside the uniform facade of this skyscraper, a private athletic club hosts an eclectic range of facilities—boxing gyms next to oyster bars and interior golf ranges below swimming pools—all segregated yet highly accessible. The Downtown Athletic Club epitomized the dynamism of New York's skyscrapers at the time, showcasing the thrill of capitalism through a selective, inward-focused world of leisure and privilege for the selected. This "machine of programs" operated independently of the external city as an isolated ecosystem within its walls. Yet, one might ask: could a similar model, designed for public use, create a more inclusive, lively community and neighborhood experience? This will activate the building within, instead of only serving the selected elites, and influence and transform the urban fabric and shapes around the building. In Hong Kong, a distant parallel can be drawn with the Municipal Services Buildings (MSBs)—publicly-funded structures that serve the community by integrating diverse functions within a singular vast building mass, much like the Downtown Athletic Club.

Reflecting on 2024, numerous architectural exhibitions have opened worldwide, addressing various themes, exhibition formats, and featured architects. Architectural design and architecture practice influence our daily lives in subtle and often unnoticed ways, where the end-users embrace built environments as they are. This reaction may arise from a combination of factors, such as a sense of powerlessness to enact significant change after a building is constructed or the experience of growing up in environments over which individuals had little or no agency in shaping. For these reasons, architectural exhibitions serve an essential purpose, offering society a chance to pause, reflect, and critically examine the myriad issues that surface during designing and building. These issues are often overlooked or need to be acknowledged, as practitioners may prioritize delivering projects within strict timelines over exploring more profound reflections.
In 2024, museums, galleries, and curators responded to the evolving challenges within the built environment with various approaches. Some exhibitions questioned the ethics of building materials and the practices behind supply chains, drawing attention to the broader implications of material choices. Others focused on documenting architectural movements worldwide, emphasizing their cultural and historical significance and the urgent need to preserve and adapt rather than replace them with entirely new builds. These efforts highlight the role of exhibitions in raising awareness about pressing issues while fostering a more critical dialogue about the architectural discipline.
