Hong Kong Architecture

Southeast Asia is often narrated as a kind of architectural playground—an arena where modern and contemporary ideals have been tested at full scale through singular, iconic buildings. One can trace an easy lineage through names that have helped shape the region's skyline imagination: Paul Rudolph's Lippo Centre in Hong Kong and The Concourse in Singapore, I.M. Pei's OCBC Centre and Hong Kong's Bank of China Tower, Norman Foster's Supreme Court of Singapore and the HSBC Main Building in Hong Kong, Ron Phillips' Hong Kong City Hall, Moshe Safdie's Marina Bay Sands. Yet this familiar history—told through objects, colonialism, authorship, and signature forms—risks missing a deeper, more consequential layer of influence: the planning logics and infrastructural frameworks that have quietly structured how these cities expand, densify, and distribute everyday life.

If elevated networks reveal a city that increasingly walks above the street, the podium–tower is the typology that often makes that condition feel inevitable. Across Southeast Asia, podium–tower projects have become one of the dominant languages of metropolitan growth: a system that concentrates housing, jobs, retail, and transit connections into highly legible and managed parcels. From an urban planning perspective, the model can be remarkably effective—absorbing congestion, formalizing circulation, and delivering density quickly. Yet as it spreads, the typology also raises a quieter question: what does it optimize for, and what does it erode—especially at the level of the street, where urban life is meant to be negotiated rather than curated?

In 2012, Cities Without Ground: A Hong Kong Guidebook offered one of the clearest documentations of a condition that many residents experience intuitively but rarely name: Hong Kong's dependence on elevated, second-storey urbanism. Through drawings and careful mapping, the book captured how the city's pedestrian networks are routinely lifted above the street—separating people from traffic, extending commercial frontage beyond ground level, and negotiating a hilly topography where "flat" circulation is often an engineered achievement. Since its publication, these systems have only grown in prominence—not only for their sheer spatial complexity, but for the way they recast public space as something continuous yet selective, connective yet curated.

Establishing thermal comfort once demanded a far more deliberate and calibrated architectural intelligence—an interplay of orientation, massing, material behavior, ventilation potential, shading, and the ways daylight and surfaces absorb and release heat. This was not simply a matter of taste, but of necessity. When many of Hong Kong's post-war modernist buildings were constructed in the late 1960s and 1970s, forming a substantial portion of the city's public housing and broader residential stock, air-conditioning was not yet a ubiquitous, default service. Cooling, where present at all, was limited and unevenly distributed; comfort had to be negotiated through passive means, through section, façade depth, operable openings, and climatic detailing. It was only later, particularly through the 1970s and 1980s, as air-conditioning became increasingly standardized across the region, that mechanical cooling began to displace this earlier matrix of architectural decision-making.

Amid the rapid build-out of data centres and AI economies across the Greater Bay Area—and alongside the celebration of AI as a tool and "author," as featured in 2025 Hong Kong–Shenzhen Bi-City Biennale of Urbanism\Architecture (Hong Kong)—a parallel question becomes unavoidable: how do the planning and construction of AI infrastructure actually begin to shape everyday life? Many of the facilities already built remain intentionally distant from daily experience. The "cloud" may be marketed as immaterial, but its architecture is profoundly physical: high-power, high-heat, service-heavy environments that are often sited in remote or low-density areas to take advantage of lower land costs and to minimize friction with nearby communities. Security and risk management further reinforce this logic. Data centres hold sensitive, privileged information—corporate assets, legal records, government and institutional data—and remoteness becomes part of their operating model, keeping the infrastructures of AI both spatially and socially out of sight.

As artificial intelligence continues to disrupt sectors of the economy and reshape entire industries, institutions and individuals alike are bracing—and rapidly adapting—to the changes that machines seem to hold over our heads. Yet the more precise pressure is not simply AI altering the way people work and live, but the business models and investment logics of the companies developing these systems: the concentration of capital, the new requirements for compute, the race for compartmentalized talent, and the infrastructural footprint needed to sustain it. In the Greater Bay Area—anchored by Guangzhou, Shenzhen, and Hong Kong—this dynamic is especially pronounced. Government-led initiatives are actively accelerating the industry's growth, with policy and planning mechanisms beginning to translate an ostensibly intangible field into physical form: zoning updates, earmarked land, and the emergence of AI-oriented building types, from research laboratories to large-scale data centers.

In Hong Kong, where interiors and small buildings are routinely caught between two extremes—high-gloss "luxury" finishes on one end, and budget-cautious industrial roughness on the other—a third attitude has emerged through the calibration of both: a uniquely precise, relevant, and materially honest execution that is not dependent on price point. This is calibrated rawness. Calibrated rawness describes an architecture that retains the directness of matter and materiality—concrete, metal, blockwork, exposed structure, visible services—while subjecting it to rigorous control.

In much of China, concrete remains the dominant construction material. Despite growing concerns over its environmental impact, concrete continues to align with the priorities of many developers and clients—it is fast, cost-effective, and highly durable. As a result, most building types in China still rely heavily on concrete. This reliance is further reinforced by China's position as the world's largest producer of Portland cement. A deeply entrenched supply chain, rooted in raw material manufacturing and economic infrastructure, ensures that concrete remains the default choice in the construction industry.

Earlier this month, news of Frank Gehry's passing prompted an outpouring of tributes to the architect behind flamboyant museums, concert halls, and sinuous residential complexes. Rather than revisit that well-charted terrain, it is worth pausing on a more contemplative work in his oeuvre: Maggie's Cancer Caring Centre in Hong Kong. Quiet, optimistic, and calibrated for everyday resilience, the building reflects multiple registers of Gehry's intent: a commitment to positivity and survival—and, more personally, an architect's own reckoning with loss and end-of-life care.

The fragility—and temporal beauty—of neon has captivated audiences since the early 1900s. First shown commercially by French engineer Georges Claude at the 1910 Paris Motor Show, neon spread rapidly, achieving broad popularity in the United States from the 1920s through the 1950s. Mid-century America saw it everywhere: from the casinos of the Las Vegas Strip to roadside motor inns along Route 66 and the spectacle of Times Square. By the latter half of the century, however, many signs were scrapped or left to decay, and numerous municipalities restricted neon as visually garish or power-hungry—despite the technology's comparatively modest energy use. In the U.S., renewed interest in neon arguably didn't meaningfully return until the early 2000s.
