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?
At its simplest, the podium–tower is a hybrid structure consisting of a high-coverage, low-rise podium supporting one or more slender vertical towers. The podium typically carries the logistical and commercial weight of the development—retail, parking, loading, drop-offs, back-of-house services, and often amenity decks—while the tower stacks private programs above, whether residential, office, hotel, or mixed use. The promise is twofold: maximize urban density while maintaining a "human-scaled" street wall, and separate the messy logistics of city life from the quieter domain of living and work.
Architecture is often evaluated through what gets built. But in many cases, what matters happens after: how spaces are used, adapted, and made part of everyday life. For Región Austral, winner of ArchDaily's 2025 Next Practices Awards, this is where design really begins. Working across many contexts, the practice approaches public space not as a single object, but as something that needs to be activated, negotiated, and sustained over time. Their projects focus less on defining form and more on creating the conditions for use, with design serving as the starting point.
This approach can be seen across different contexts, from the Olympic Neighborhood Square to the Playón de Chacarita network. While each project responds to a specific situation, both explore how public space can support collective life in areas marked by fragmentation and inequality. Instead of following a predefined approach, the work adapts to different urban conditions, using participation and incremental strategies to shape how spaces function over time.
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.
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.
This fascination, however, has always carried a parallel unease. Elevated passages can be generous and effective, offering sheltered movement and reliable connectivity. Yet they also raise persistent questions: where do these routes lead, who gets to connect, and what kinds of programs are invited—or excluded—by this "privileged" level of circulation? The second-storey city does not simply bypass vehicles; it can also bypass the street as a civic stage. Over time, it risks shifting architectural attention away from ground-level public life, relieving designers from having to negotiate pedestrian scale, frontage, and the messy reciprocity of the street. In its worst moments, the result is a landscape of podium clusters and sealed megastructures—buildings that perform connectivity at Level 2 while remaining indifferent to the neighborhood at Level 0.
What do lightweight materials bring to public space with an ethical, ecological, and non-extractive design principle? Various textile textures offer a point of entry, being closer to the body than heavy conventional structural materials. Through its flexibility and responsiveness, it enables a form of soft enclosure rather than a fixed boundary in architectural space. Responding to minimal environmental stimuli, the fabric brings continuous movements into space. When layered or assembled, it produces gradations of density, depth, and enclosure, while recent innovative fabrication technologies extend the possibilities of its form and structural durability.
Semi-transparent materials further mediate the conditions of visual permeability and bodily experience of the space. By transmitting and filtering light, they blur clear separations between interior and exterior, solid and void, creating thresholds that are neither fully open nor fully enclosed, but constantly in negotiation. Reinterpreting structure in urban space through lightweight, translucency, and softness opens up alternative modes of spatial perception and bodily engagement.
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.
In recent decades, cities across the world have seen an increase in the demolition of elevated concrete freeways. Taipei, Seoul, Portland, and Boston, for example, have all seen the rise and fall of these infrastructures to give way to parks and new urban regeneration ideas. In other cases, like Montreal in Canada, some people opposed the freeways even before they were built, effectively rerouting viaducts, preserving heritage, and freeing waterfront views. For San Francisco, in the United States, the story of the Embarcadero Freeway is one of those narratives that serves as a case study of the city's mid-century infrastructural ambition, people's reaction to the project, and its eventual reversal in favor of urban connectivity.
Paris's 19th arrondissement Parc de la Villette is undergoing a major transformation, combining a newly opened urban farm with restored biodiversity as part of a strategy to adapt the 55.5-hectare park to climate change. Masterplanned by Bernard Tschumi in 1982 and opened to the public in 1987, the park stands as a landmark of European modernism in public space design, breaking from the traditional concept of the metropolitan park. With a 15,000-square-meter extension, this major green lung in northeast Paris is reimagining its lawns as a living laboratory for environmental education, where animals, plants, and humans coexist. The extensive renovation follows the addition of Tschumi's HyperTent in 2022, a hyperbolic paraboloid structure functioning as a new ticket booth on the podium of Folie L4, and marks the park's most significant transformation since its inauguration.
Cultural centers continue to serve as a productive ground for unbuilt architectural exploration, reflecting how architects are rethinking the role of public institutions in relation to landscape, experience, and program hybridity. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that expand the definition of the cultural center beyond a singular building. These works position architecture as a spatial framework that mediates between research, exhibition, retreat, and public life, often embedded within or distributed across natural and urban contexts.
Across varied geographies, from northern Norway and Oslo to Łódź, Vienna, Marrakech, and New Tashkent, the projects demonstrate diverse responses to cultural infrastructure. They include landscape-integrated complexes shaped by topography and climate, bridges that combine gallery and public circulation, zoological pavilions structured as immersive sequences, adaptive reuse of military buildings into performance spaces, courtyard-based environments rooted in local traditions, and climate-responsive institutions informed by environmental analysis. Together, these proposals explore how cultural programs can be organized through movement, spatial layering, and relationships between interior and exterior conditions.
Death is a certainty, but its architecture has never been stable. Every period and culture has invented a different way of placing the dead in the world (close or far, visible or screened, monumental or almost anonymous), and those choices have always carried social and political weight. Cemeteries are where that weight becomes legible in space, turning belief and regulation into boundaries, paths, and names.
In that sense, a cemetery behaves like a piece of city-making. It needs access, limits, and an internal order that can grow without losing clarity. It depends on ground and water management as much as on symbolism, and on administration as much as on form. But its real architectural problem is how to make a large, evolving territory readable while preserving the intimacy of a visit. Names must be locatable; routes must remain legible; trees grow, paths shift, stones weather, records accumulate. What looks fixed is, in practice, a living system designed to be used and revisited, long after the first grief has passed.
This week has been marked by the deliberate, rampant, and unjust destruction of war in Southeast Asia. As one of the most damaging manifestations of human abuse of power, we have witnessed the destruction of places that hold memories and sustain culture, as well as the loss and irreparable harm to the human lives that lend them their identity. With the expectation of offering brighter and more constructive scenarios in the future, we present, in contrast to this reality, a scenario of progress in the gender gap that characterizes architecture and its paths forward, a group of landmark projects of public and community interest moving forward from Türkiye to Mexico, and three major multimodal transport infrastructure projects improving the way we circulate and inhabit public space in Europe and the United States.
Urban masterplans remain an exploratory ground for unbuilt speculation, offering insight into how cities might recalibrate mobility, ecology, and collective life in response to accelerating environmental and social pressures. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of large-scale proposals that examine urban centers, waterfront districts, infrastructural corridors, and cultural landscapes as spatial frameworks for reconnection and resilience. Rather than treating the masterplan as a rigid blueprint, these projects approach urbanism as an adaptive system shaped by climate, topography, infrastructure, and public space.
Across varied geographies, from Northern European town centers and Mediterranean coastal districts to Central Asian polycentric hubs and Gulf megacities, the proposals explore diverse architectural and urban strategies. They range from park-led civic transformations built over highway tunnels to elevated pedestrian networks above active transport systems, mixed-use blocks structured by historic planning logics, marina developments integrating environmental stewardship, and research-driven models for equitable landscape urbanization.
Architecture is often evaluated through finished forms, yet some practices operate in a different register, one where design unfolds through relationships, time, and use rather than through a single outcome. For CatalyticAction, participation is not a parallel social activity, but the means through which spaces are conceived, constructed, and sustained over time.
Based between Beirut and London, the practice has worked across the Middle East and Europe, developing public spaces, schools, playgrounds, and everyday urban infrastructures through long-term collaboration with local communities. Grounded in participatory research and collective decision-making, this approach was recognized through ArchDaily's 2025 Next Practices Awards, highlighting a mode of practice where architecture is understood as a shared, evolving process rather than a fixed object. In this context, architectural value is measured through continuity, use, and collective ownership, rather than through form alone.
Concéntrico is an urban innovation laboratory that invites reflection on the city through architecture and design. Since 2015, it has carried out more than 180 interventions in Logroño, Spain. The new 2025/2026 season of the festival expands on this experimental spirit with three international calls for proposals that bring the ideas in the book Concéntrico: Laboratorio de Innovación Urbana (Park Books, 2025) into action. Through these calls, the organization seeks to explore further three lines of research, the ephemeral, the ecological, and the symbolic, to imagine different ways of inhabiting the city. The winning projects from this edition's calls for entries will be developed, built as urban installations, and presented in the exhibition during the festival, taking place in Logroño from June 18–23, 2026.
Cities around the world share a common goal: to become healthier and greener, supported by civic infrastructure that restores ecosystems and strengthens public life. The question is how to reach this. Global climate targets, local building codes, and municipal standards increasingly guide designers and planners toward better choices. Still, many cities struggle to translate these frameworks into everyday, street-level comfort and long-term ecological protection. What happens if the city is no longer treated as a traditional city, but as a national park?
National parks operate through systems of protection that treat land as a network of ecological relationships rather than a collection of isolated sites. They establish a shared baseline for what must be preserved, maintained, and made accessible over time. When this logic is applied to the urban environment, success can inspire pride and a sense of shared responsibility among designers, policymakers, and residents, fostering a collective commitment to health, habitat, and civic infrastructure.

You learn how to behave long before you arrive home. At the gate, you slow down and wait. You are watched, then waved through. A badge is checked, a barrier lifts, a camera blinks. Nothing dramatic happens, and that is precisely the point. The most consequential work of gated communities is not done by their walls, but by the choreography of entry that quietly teaches residents what to expect, whom to trust, and where they belong.
