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.
Cities today are being reimagined as living, evolving organisms, combining digital intelligence, ecological systems, and new materials to shape radical futures. At Carlo Ratti's "Intelligens. Natural. Artificial. Collective." biennial, over 750 participants challenge established boundaries between architecture, landscape, and technology. Several conceptual projects showcased in the main exhibition challenge conventional boundaries between architecture, landscape, and technology. From bio-adaptive urban systems and Martian water-based settlements to immersive symphonies of satellite data, these works collectively envision new models for cohabitation, resilience, and planetary awareness.
This month's Unbuilt selection presents six speculative projects, presented as part of the 2025 Venice Architecture Biennale exhibition, as provocations for rethinking the future of cities and human settlement. While some proposals transform architecture into self-sustaining, living infrastructures, others explore how data and sensory interfaces can redefine our relationship with natural and urban environments. Together, they offer a cross-section of how architects and designers are using unbuilt work to imagine new possibilities for life on Earth and beyond.
The summer of 2025 has brought extreme heat across Europe and beyond, with record-breaking temperatures and widespread climate-related impacts. Red alert warnings have been issued in France, Italy, and Spain as temperatures exceeded 46°C in parts of the Iberian Peninsula. These conditions have led to school closures, restrictions on outdoor work, and pressure on urban infrastructure, including power grids and public transport systems. The heatwave has simultaneously intensified wildfire risk across the Mediterranean. In western Turkey, ferocious wildfires near Izmir forced the evacuation of over 50,000 people as high winds and low humidity fueled rapidly spreading flames. In Spain's Catalonia region, two people died in a wildfire that raced across farmland and old structures in Torrefeta on July 1. Similar disasters have occurred in Greece, France, and Italy, with evacuations throughout southern Europe as widespread heat‑induced drought exacerbates fire season intensity.
BIG, artist Doug Aitken Workshop, NIRAS, Volcano, and RWDI have won a competition to redesign three public spaces surrounding major music venues in Ørestad, Copenhagen. The initiative, titled Byens Scene ("The City's Stage"), aims to revitalize the areas around DR Koncerthuset, Bella Arena, and Royal Arena, transforming them into an interconnected landscape for everyday use and public performances.

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.
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.
Léon Krier's Sketches. Image Courtesy of MIT Press
Léon Krier, the Luxembourg-born architect and urban theorist renowned for his critical stance against modernist planning and his influential role in the New Urbanism movement, passed away on June 17, 2025, at the age of 79. Known for his uncompromising critique of modernist planning and his vision for human-scaled, walkable communities, Krier leaves behind a substantial body of built work, theoretical writing, and educational influence.
Over a career spanning several decades, Krier advocated for a return to classical architecture and human-scaled urbanism, positioning himself as a leading critic of sprawling suburban development and high-rise modernism. His advocacy for walkable, mixed-use neighborhoods and his insistence on the cultural and social value of architecture challenged the prevailing norms of late 20th-century urban planning.
The 11th edition of Concéntrico, the International Festival of Architecture and Design, is currently taking place in Logroño, Spain, from June 19 to 24, 2025. This year's edition broadens the scope of the festival with a multifaceted programme that includes not only temporary installations but also permanent projects, exhibitions, educational initiatives, and traveling events. Through 24 urban interventions, Concéntrico 2025 explores themes such as material reuse and circular design, food as a collective practice, the recovery of water-related spaces, the activation of urban voids, and interspecies connections in the urban context, while emphasizing the need to imagine new ways of inhabiting the city, placing care, sustainability, empathy, and active listening at the core of public architecture.
Zaha Hadid Architects (ZHA) has unveiled images of a master plan for Khalid Bin Sultan City in Sharjah, United Arab Emirates. Located adjacent to its BEEAH Headquarters, the development draws inspiration from that building's design, incorporating fluid architectural forms reminiscent of wind-swept desert dunes. Planned as a design and business district, the new urban area will consist of seven residential neighbourhoods connected by shaded walkways and anchored by a two-kilometre-long central oasis.
Public space has long been central to architectural thought, often framed in terms of planning, infrastructure, and regulation. From Haussmann's Paris to contemporary masterplans, architects have worked to define and formalise collective life through spatial tools. Yet, outside of these frameworks, artists have continuously offered alternative ways of understanding and inhabiting public space—ways that rely not on construction or permanence, but on presence, perception, and participation. Through actions, objects, or atmospheres, artists engage the city as a site of friction and imagination. These gestures challenge architectural conventions and invite artists to reconsider public space not as a solved form, but as a contingent and open process.
Friends of + POOL has announced the next steps in the realization of New York City's first water-filtering floating swimming pool, to be installed at Pier 35, north of the Manhattan and Brooklyn Bridges. The project seeks to provide safe public access to swimming in the city's rivers by integrating a custom-designed filtration system into a floating pool structure. Installation at Pier 35 is scheduled for May 2026, when the pool will enter its final phase of evaluation. Public access will be contingent on the successful completion of large-scale filtration testing and the full build-out of the facility for safe public use.

Architecture firm HWKN has been commissioned by Al Marwan Real Estate Development to design eleven distinct buildings for a new commercial neighborhood in central Sharjah, the third most populous city in the United Arab Emirates. The district, featuring offices, retail spaces, cafés, childcare and healthcare facilities, specialized institutes, and a mosque, has been fully researched, conceptualized, and planned using Artificial Intelligence (AI).
"The limits of our design language are the limits of our design thinking". Patrik Schumacher's statement subtly hints at a shift occurring in the built environment, moving beyond technological integration to embrace intelligence in the spaces and cities we occupy. The future proposes a possibility of buildings serving functions beyond housing human activity to actively participate in shaping urban life.
At the turn of the millennium, the world was gripped by the looming threat of the Y2K bug, a potential failure of computerized systems that could disrupt everything from banking to aviation. As midnight approached on December 31, 1999, people withdrew their savings, major corporations issued warnings, and governments scrambled to prevent public hysteria. But as the sun rose on January 1, 2000, the feared bug had no material impact, and the crisis faded as quickly as it had emerged. However, this era left its mark in unexpected places — particularly in architecture. Amid the anxiety surrounding digital technology, one of the most iconic concert halls of our time, Casa da Música in Porto, was born. Designed by OMA (Office for Metropolitan Architecture), its origins can be traced to a much smaller project: the Y2K House. What began as an exploration of private domesticity during the digital scare evolved into a grand public structure — an architectural transition from home to a performance hall.

Danish architecture firm Third Nature, together with Sophie Sahlqvist Landskab, Arkaia, ILC, and Artelia, recently shared images of Øhjem, their proposed strategic vision for the re-naturalization of Denmark's Greater Copenhagen region toward 2050. The regenerative plan is part of the Water's Ways program under the Agenda Earth initiative, an interdisciplinary project run by the Danish Association of Architects in collaboration with the Dreyers Foundation and the Danish Bar Association. Led by urbanist Boris Brorman Jensen, the program calls for long-term solutions to restore 15% of Danish agricultural land while also protecting 600,000 homes from water-related threats. Third Nature's Øhjem masterplan reimagines the 25 km Ramsø Dale as a step toward implementing the land management objectives outlined in the Danish Green Tripartite Agreement (Grøn Trepart), signed in June 2024.
How do pavilions emerge in architecture? What role do they play in urban spaces? Beyond the multiple interpretations that exist around the world, the pavilion, as an architectural principle and typology, tends toward extroversion, often associated with a centrifugal nature and visual openness toward the horizon, which is linked to its origins as a tent offering shelter from the elements. Pavilions are usually identified as isolated and independent structures that can promote lateral openings in the urban space, panoramic or introspective views, technological reflections, and material experiments that are recognizable from the outside or once inside.
