Playscapes and Public Imagination: The Ambiguous Play in Urban Life of Hong Kong

When we think about cities and urban life, we often focus on infrastructure, culture, commerce, nightlife, and density. In metropolises where there seems to be an endless array of activities—especially for adults—play rarely enters the conversation. Yet, the act of playing should be considered a vital part of urban life. Play directly influences how we shape our future cities—starting with how children engage with their environments. The experience of play, and more specifically, the design and presence of playgrounds, leaves lasting impressions on how young people grow up in cities. These spaces form a child's first, physical connection to the urban landscape. In this way, play deserves far more attention in conversations around urban wellness, livability, and the design of public space.

Longevity Through Renewal: The Enduring Wisdom of Hong Kong's Water Villages

While Hong Kong is widely celebrated for its iconic harbor view, glittering skyline, and fast-paced urban lifestyle, its origins tell a different story—one deeply rooted in its relationship with water. Before transforming into a dense, vertical metropolis, Hong Kong's architectural identity was closely tied to its maritime context. Today, the city is often associated with slender, glass-clad towers that symbolize modernity. While visually striking in their pursuit of height and form, many of these buildings appear disconnected from their immediate environment, often overlooking natural site conditions, ecological responsiveness, and contextual sensitivity.

Historically, however, this was not the case. Hong Kong's earliest built environments—rural fishing villages in areas like Tai O, Aberdeen, and Shau Kei Wan—emerged through organic, community-driven spatial practices that engaged closely with their surroundings. These coastal and riverside settlements developed architectural systems tailored to the marine environment and to the rhythms of fishing life. Villages were sited around water, and construction strategies were adapted to fluctuating tides, terrain, and social use.

Village in the Vertical City: Tai Hang and the Afterlife of Vernacular Hong Kong

Vernacular architecture in Hong Kong originated as a series of small, coastal settlements—simple, village-like communities that reflected the city's early identity as a fishing hub. These seaside villages were typically composed of low-rise, timber-framed houses clustered around temples, forming tight-knit communities closely tied to the rhythms of the water.

One notable example is Tai Hang, among the earlier settlements established by the Hakka people in Hong Kong. Originally located along a water channel that flowed from the nearby mountains to the sea, the area was once a vital washing site for villagers—hence its name, which literally means "Big Drainage." Before extensive land reclamation, Tai Hang sat quite close to the shoreline. Today, it lies nearly 700 meters inland.

Architectural landmarks often cluster together. In Tokyo, the iconic Omotesando is a well-known stretch where global "starchitects" built flagship luxury retail spaces in the 2000s. Hong Kong has a lesser-known but equally powerful architectural agglomeration along Queensway—though historically more corporate and less publicly engaging. Beginning in the 1980s, this corridor became home to a series of landmark buildings by some of the world's most prominent architects: Norman Foster's HSBC Headquarters, I.M. Pei's Bank of China Tower, Paul Rudolph's Lippo Centre, and the nearby Murray Building by Ron Phillips—now revitalized as a hotel by Foster + Partners. The area is further enriched later on by Heatherwick Studio's renovation of Pacific Place and Tod Williams Billie Tsien Architects' Asia Society Hong Kong Center.

Built to Last—or Change? The Case for Dry Construction in Humid Cities

Subscriber Access | 

In certain parts of the world, construction is still dominated by wet systems—concrete, masonry, and cementitious materials that are poured, cured, and fixed in place. While this has long been considered the norm in some south-east Asia countries, such as Singapore, Thailand, Malaysia, and China, in most of these regions, they typically share a common trend where labor is relatively inexpensive. This serves as one of the reasons to make concrete more easily available, as one of the typical downside of concrete is its intensive labour cost - this further differentiates concrete as a cheaper and more efficient material system to be building out of.

However, not enough considerations in the region are given to the sustainability aspect when using these wet construction materials,often overlooking the significant drawbacks of its material lifecycle and the difficulty to recycle it without downcycling - making it one of the more unsustainable materials available to be built out of.

Courtyardism: A Vision for a More Balanced Urban Future in the Greater Bay Area by Wang Weijen Architecture

Situated in one of the fastest-developing regions over the past decade—the southern part of China, including Hong Kong and the Greater Bay Area—urban growth has been driven by an overwhelming wave of commercial ambition. Projects here are often designed for maximum density, height, and efficiency, resulting in developments of enormous scale that can easily span several acres. Prioritizing transit-oriented development, these complexes frequently take the form of sprawling malls built directly above major transportation hubs. Designed to disorient and prolong foot traffic to encourage economic activities, these mega-structures have become commonplace in cities like Hong Kong and Shenzhen.

While this typology of megastructures offers clear advantages—economic efficiency, high development returns, and convenience for transit users—it almost invariably ignores its urban context and environment. These developments often turn a blind eye, deliberately so, to their environmental footprint and the city's walkability. At such overwhelming scales, the human walking experience is diminished, if not outright neglected. Pedestrians become interiorized—trapped within the insulated world of these complexes.

Unwrapped Interiors: A Case for Material Authenticity and Clarity

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?

Architecture Details 101 in Venice: Carlo Scarpa and David Chipperfield in Dialogue Across Time

In Venice, surrounded by an overwhelming abundance of architectural beauty—the grandeur of landmarks like the Basilica di San Marco, St. Mark's Square, and the Rialto Bridge, to name just a few—it is easy to become swept up in the iconic imagery and spatial majesty of the city. One could lose sight of the quieter, yet equally masterful, moments found in the execution of details across its built fabric. Beyond the grandeur, the city offers a richness in its winding alleyways, narrow canals, and vibrant street life—each contributing to the cultural tapestry that makes Venice so unique. Amidst these celebrated elements, however, lie subtle but remarkable architectural details that often go unnoticed. These deserve closer observation and reflection, as they offer their own kind of mastery—one grounded in material precision, craft, and the lived rhythms of the city.

Just steps away from the iconic Piazza San Marco, a quiet architectural dialogue unfolds between two celebrated figures. Within a one-minute walk, two projects—each meticulously crafted—sit in close proximity: the Olivetti Showroom by Carlo Scarpa, a long-revered pilgrimage site for architects and designers, and the recently reopened Procuratie Vecchie, restored by David Chipperfield Architects. A closer look at the architectural details embedded within each work reveals a compelling exchange across time—one that unfolds through material language, spatial precision, and an unwavering commitment to craft.

The Intelligence of What Remains: On Archiving and Architectural Knowledge

When we speak of intelligence at the 2025 Venice Biennale, the main exhibition broadly categorizes it into three domains: natural, artificial, and collective. While much attention has been drawn to robotic performances, future-forward material experiments—such as Boonserm Premthada's elephant dung bricks, or Canada's display of mesmerizing picoplankton, one often overlooked yet critical form of collective intelligence lies in the act of archiving.

Several national pavilions showcase this collective intelligence through beautifully curated exhibitions—the Spanish Pavilion's witty play on scale, for instance, features meticulously crafted models that invite close reading and delight. These curated collections offer a snapshot of the present, and in some cases, gestures toward the future. But without critically engaging with the past, without documenting and making sense of our shared spatial and architectural knowledge, the potential of collective intelligence remains incomplete. Archiving is not simply an act of preservation; it is a generative tool for projecting new futures.

Beyond the Blueprint: Archiving Architecture as Collective Intelligence

When we talk about the future intelligence of architecture, much of the historical effort has centered on pushing boundaries—challenging norms, exploring alternatives, and projecting bold visions of what architecture could become. The advent of modernism exemplified this approach: radical new materials and construction methods gave rise to a vastly reimagined architectural future. This momentum continues today, with research institutions and leading practices constantly exploring innovative techniques, materials, and systems of making.

Yet one method of imagining architectural futures often remains overlooked: the act of critically revisiting the past. Learning from, uncovering, and documenting lesser-known spatial and communal practices is just as essential. These quieter forms of knowledge—how spaces have been used, adapted, and inhabited—can reveal enduring insights that shape more grounded, culturally resonant futures. Rather than chasing novelty for novelty's sake, perhaps an equally meaningful path lies in building a cohesive architectural archive that bridges the past and future.

Designing for Companionship: Reimagining Urban Life with Pets

Humans and pets have long shared a deep and inseparable bond—and today, how we live alongside them is becoming increasingly important. Beyond offering companionship, pets are now often regarded as life partners, providing powerful support for mental health and emotional well-being. Yet it is not only the emotional connection that matters: the way we design and curate spaces for cohabitation with them plays a critical role in shaping meaningful spatial relationships between humans and their animal companions.

Whether through custom-designed furniture or more seamlessly integrated solutions like wall cavities and built-in nooks, an increasing amount of attention is being paid to how we can better coexist with pets in our homes. This shift reflects more than just affluence or pet ownership; it signals a broader evolution of companionship—one rooted in mutual support, emotional health, and shared environments.

Earth Day 2025: Our Agency in Rethinking Sustainability Across Cities, Scales, and Sectors

Subscriber Access | 

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.

From Common Sight to Cultural Symbol: The Rise and Decline of Bamboo Scaffolding in Hong Kong

Subscriber Access | 

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.

The Quiet Tensions of POPS: How Private Institutions Shape Public Urban Wellness and Access

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.

Taming Nature: How Architecture is Redefining Its Relationship with the Environment

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 Hidden Mechanics of Doors: How Hinges, Tracks, and Pivots Shape Spatial Experience

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.

The Evolution of Public Bathhouses: From Necessity to Experience

Subscriber Access | 

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.

Touching the Earth Lightly: How Freeing the Ground Plane Shapes Architectural Atmosphere

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.
