Infrastructures: The Latest Architecture and News

When London's main drainage was completed north of the Thames in 1868, the Metropolitan Board of Works marked the occasion with a banquet held inside a sewage pumping station. Abbey Mills had been built over the previous three years by the engineer Joseph Bazalgette, working with the architect Charles Driver, laid out on a cruciform plan with eight beam engines, two on each arm. Its style has been read as Byzantine, Italian Medieval, Russian, Ruskinian Gothic and Moorish, and its twin ventilation chimneys, richly ornamented, rose more than sixty meters. The builder called it an elegant structure in a swamp and thought it might pass for a mosque or a temple.

Almost everything else Bazalgette built was buried, and the exception did not last the century. Steam gave way to electric motors at Abbey Mills in 1933, and the chimneys, redundant since then, were demolished in 1941 out of fear that a bomb strike would topple them onto the station. Sanitary engineering consolidated around criteria that could be measured, among them throughput, discharge quality and hydraulic gradient, and appearance registered in none of them. Treatment moved outward to floodplains, estuaries and municipal edges where land was cheap, and gravity did useful work.

For most children, the journey to school is an everyday geography of street life and traffic, repeated so often that it becomes almost invisible, folded into the background of childhood and growing up. Yet for cross-boundary students who live in Shenzhen and attend school in Hong Kong, the school day begins much earlier, and much farther from the classroom. It begins at the border.

Their commute is not simply a matter of distance. It is shaped by two legal systems, two administrative cultures, and a set of infrastructures designed to make daily crossing a little bit more feasible for individuals under 18. On a typical morning, the route to school may pass through a boundary control point before it reaches a classroom. It may involve a government-approved school coach, a restricted access road, an immigration hall, a fingerprint scanner, or a clearance procedure that takes place while the child remains seated on the bus. What appears from a distance as a school commute is, in spatial terms, a carefully managed architectural corridor between two cities.

How can the most structured elements in architecture give rise to unplanned forms of everyday life? "Spontaneous order" describes how structured systems can generate unplanned but coherent patterns of behavior. In urban discourse, it is often used to describe cities: frameworks of streets, plots, and buildings that are designed, while everyday life is not. Movement, encounters, routines, and informal uses emerge from simple spatial rules rather than explicit programming. In cities, this is visible in how sidewalks, stations, and thresholds operate. The structure is fixed, but the social order is fluid, setting conditions for behavior rather than defining it.

A similar logic can be observed in architectural micro-infrastructures such as locker systems. Like cities, lockers rely on structured frameworks that do not prescribe how life unfolds within them. A locker system is highly controlled in architectural terms: repetitive modules, strict grids, standardized dimensions, controlled access. Yet once in use, it produces spontaneous behaviors. People pause in corridors, return at irregular times, linger near locker zones, or briefly interact with others doing the same. What appears to be a strictly infrastructural storage system begins to generate informal social and spatial behavior.

Elevation is often framed as progress, lifting movement above the friction of the city and smoothing circulation into uninterrupted flow. Every act of lifting produces a secondary condition in its wake. Beneath flyovers, metro lines, and railway viaducts, a second ground emerges as shaded, ambiguous, and rarely planned with the same intent as what moves above. These spaces are not incidental leftovers. They are the spatial consequence of a design decision that privileges speed, clearance, and efficiency, redistributing value and visibility across the city in the process.

What lies below is not empty. It is structured, constrained, and defined by infrastructure, left without a clear role. Studies on elevated highways consistently describe these undercroft zones as residual spaces, formed when transport systems are conceived independently of the ground they pass through. An Arup report on spaces beneath viaducts notes how they often disrupt pedestrian continuity while remaining outside formal planning frameworks. Similarly, recent academic reviews of under-flyover environments highlight that these areas are rarely integrated into urban design strategies at all. The result is a peculiar condition: space that is physically present and structurally determined, but programmatically undefined.

Architecture has long been drawn to the idea of lightness. From early modernist experiments that sought to preserve landscapes, elevating buildings has been understood as a way to preserve the ground while maintaining continuity across the terrain. Volumes are lifted on columns, infrastructures detach circulation from the surface, and entire programs are suspended above the ground.

This was formalised in the early twentieth century through Le Corbusier's concept of the pilotis, which proposed the liberation of the ground floor from enclosure. By raising buildings on columns, architects sought to maintain continuity with the terrain, allowing movement, vegetation, and collective use to unfold beneath constructed volumes. The building would occupy the air, while the ground would remain open, accessible, and shared.

Foster + Partners, in collaboration with Angola's Ministry of Transport, has unveiled the master plan for the Icolo e Bengo Aerotropolis, a large-scale development planned around the recently completed Dr. Antonio Agostinho Neto International Airport. The proposal organizes business, research, residential, and hospitality programs within a landscape-led framework structured around the airport. Development is planned to proceed in phases, beginning with the business and cultural district located to the north of the site.

Faced with the combined forces of population growth, economic prosperity, and urban expansion, cities are witnessing a significant rise in the movement of people and goods—mirroring the evolution of diverse mobility systems within urban environments. As technologies advance and modes of transport evolve, the adaptive reuse of train carriages, airplane cabins, and other service infrastructures reveals opportunities to explore their creative potential. Materials, technologies, and design tools converge around a shared goal: refurbishing and repurposing disused structures to give them new life.

Marginalized in architectural discourse and often dismissed as purely functional, parking garages remain among the most ubiquitous structures in the urban landscape. Designed to accommodate the needs of private vehicles, they occupy central locations, shape skylines, and consume considerable resources, yet rarely receive the same attention — or architectural care — as cultural institutions, schools, or housing. Despite their prevalence, these buildings tend to fade into the background of daily life, treated as infrastructural necessities rather than as design opportunities.

This is beginning to change. As urban mobility undergoes profound transformations — from the decline of car ownership to the rise of electric vehicles and shared transport systems — the role of parking infrastructure is being redefined. Architects and planners are reimagining garages as adaptable frameworks that integrate public space, ecological functions, and mixed-use programs. These new approaches challenge the perception of parking as a residual typology and instead position it as a civic structure with the potential to support more inclusive, flexible, and sustainable urban models.

Urban playgrounds are evolving from simple swing sets and slides into dynamic, multi-faceted urban landscapes. These new designs are more than just places to play; they are thoughtfully integrated spaces that address urban challenges, promote community, and inspire creativity. A key trend is the intentional use of color and pattern. Designers are utilizing vibrant color zones to segment different functional areas, creating a visually dynamic experience that contrasts with natural surroundings. This approach can also be used to establish a cohesive urban identity, with thoughtful color palettes that complement the existing cityscape.

Amidst global economic adjustments and a domestic focus on high-quality development, Shanghai has implemented a strategic shift in its urban development approach—moving from 'incremental expansion' to 'connotative enhancement.' Guided by the concept of a "people-oriented city", Shanghai has elevated urban construction from mere physical space aggregation to a comprehensive endeavor aimed at optimizing functional quality, revitalizing spatial vitality, and boosting residential resilience through urban renewal initiatives. This transformation is framed not merely as a response to resource constraints but also as an intentional approach to urban development principles. Its core proposition lies in: under the policy framework of strictly controlling incremental land use, how to unleash development potential through the "reproduction" of existing spaces.

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.

The Economist Intelligence Unit (EIU) has released its Global Liveability Index for 2025, assessing 173 cities worldwide across five categories: stability, healthcare, culture and environment, education, and infrastructure. This year, Copenhagen has taken the top position, ending Vienna's three-year run as the world's most liveable city. The Danish capital earned high scores in stability, education, and infrastructure, narrowly surpassing Vienna, which saw a decline in its stability rating following recent security incidents. The average global liveability score for 2025 remains steady at 76.1 out of 100, unchanged from 2024. While year-on-year improvements were recorded in healthcare, education, and infrastructure, these were offset by a continued decline in stability, driven by rising geopolitical tensions, civil unrest, and increased security threats in several regions.

What structures and infrastructures sustain the ties and relationships between the countryside and the city? How will architecture and emerging technologies maintain -or not- the coexistence of both worlds in the future? The reduction of ecological footprints, the impact of climate change, the decentralization of major cities, food security, and other contemporary issues challenge professionals in architecture and urbanism globally under the main shared goal of improving citizens’ quality of life and achieving physical, mental, and emotional well-being in both built and natural environments.

The gas station is an architectural typology that has undergone significant transformations since its inception. Initially, these structures were simple roadside refueling points designed for functionality rather than aesthetics. As automobile culture expanded, gas stations evolved to accommodate new technologies, shifting urban landscapes and changing consumer behaviors. Over time, they became more than just utilitarian stops — they developed into service hubs, integrating restaurants, motels, and leisure spaces, responding to contemporary transportation increasing demands.

By the late 20th century, however, the widespread standardization of gas stations led them to be perceived as "non-places", a concept defined by anthropologist Marc Augé to describe transient spaces that lack social or cultural significance. With uniform designs and a focus on efficiency, gas stations became interchangeable, reinforcing their role as purely functional infrastructure rather than meaningful architectural interventions. This standardization also departed from the era when fuel stations served as recognizable landmarks, contributing to a homogenized landscape devoid of local identity.

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.

How can architecture professionals transform the atmosphere of a structure? What kinds of interventions can go beyond adaptive reuse to modify spatial perception? As architectural structures are repurposed over time, new uses and needs emerge between spaces and their users. While the structures of old buildings keep the memory of communities alive, the introduction of new life through greenhouses, housing, commerce, offices, or cultural centers brings about new atmospheres where light, ventilation, the integration of nature, and other elements reshape interior experiences.
