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.
Heritage preservation and economic viability have long been treated as competing priorities in urban development. Architects typically face a stark choice - to design for community continuity or design for financial returns. Contemporary projects in Mumbai render this binary false. Through strategic programming, material choices, and spatial organization, architects enable buildings to generate sustainable revenue while strengthening, rather than displacing, existing communities.

The concrete canyon of Melbourne's Degraves Street was once a stark service corridor in functional obscurity. Today, the narrow laneway now pulses with life beyond its famous café. Native grasses cascade from carefully positioned planters while small shrubs create cooling microclimates. Challenging traditional ecological design models, community-led approaches to biodiversity invite a reimagining of how architects, planners, and communities collaborate to develop biodiverse urban futures.
From forest-inspired offices in Sweden to jungle-nest clubhouses in Tulum, mixed-use architecture continues to evolve as a tool for integrated living. As cities grow and our expectations of public, private, and commercial space shift, designers are increasingly rethinking how different functions including work, play, rest, learning, can coexist in a single architectural language. These projects suggest that buildings and projects no longer need to silo activities, but rather choreograph them to reflect the rhythms of everyday life.
This collection, submitted by the ArchDaily community, presents a global spectrum of approaches to mixed-use design, from large-scale masterplans to conceptual theses. What ties them together is a commitment to spatial overlap, ecological sensitivity, and reimagined programs that prioritize user experience. Whether it's a student dormitory in Tehran, a public plaza in Cairo, or a community hub in Texas, each project embraces complexity to create spaces that are alive with interaction, transformation, and meaning.
In the complex ecosystem of architectural development, where innovative concepts meet market realities, a distinct role exists to bridge diverse professional interests and realize impactful spaces. Elisa Orlanski Ours exemplifies this function. This is the domain of Elisa Orlanski Ours, a designer, educator, and industry leader. As Chief Planning & Design Officer at Corcoran Sunshine Marketing Group, Elisa founded her department two decades ago. Now, her extensive portfolio spans condominium skyscraper master plans and individual branded villas across continents, including significant New York City developments like Hudson Yards and 220 Central Park South, as well as international developments in collaboration with prominent architectural firms like SHoP Architects, BIG, Herzog & de Meuron, Adjaye Associates, and SO-IL. Her strategic perspective on bringing projects from schematic phase to final sale provides valuable insights into the industry's intricate workings. ArchDaily's Managing Editor, Maria-Cristina Florian, had the opportunity to discuss these critical topics with Elisa in the following interview.
In 1982, at a conference on earth building in Tucson, Arizona, an unusual presentation challenged everything architects thought they knew about rural resources. Instead of focusing on construction techniques, the presenter, architect Pliny Fisk III, spread out a series of hand-drawn maps that revealed something extraordinary - rural Texas wasn't resource-poor, as conventional wisdom suggested, but material-rich beyond imagination. The maps showed volcanic ash perfect for lightweight concrete, caliche deposits stretching across vast territories, and mesquite forests that could supply both hardwood flooring and insulation. The revelation redefined prevailing notions of value in architecture.

The House of Culture and Administration, a new civic complex designed by Benthem Crouwel Architects in collaboration with Snøhetta, is gradually taking shape in the Dutch city of Delfzijl. Located at Molenbergplein, the project brings together cultural and administrative functions in a unified architectural gesture that aims to strengthen the urban fabric of Eemsdelta. The current visualization marks a step forward in the structural design phase. Technical and financial refinements will continue over the summer, with final approval from the municipal council expected in October 2025.
Swimmable Cities is an alliance of 153 signatory organizations across 59 cities in 22 countries, supporting the global movement for swimmable urban waterways. In the context of increasing urbanization, climate change, and biodiversity loss, the initiative aims to reclaim rivers and harbors as public spaces for communities to enjoy and benefit from bathing. It advocates for urban waterways to be made safe, healthy, and accessible for both swimmers and wildlife, calling for cross-border collaboration to develop improvement strategies and collect data to evaluate "swimmability." This call becomes especially relevant amid rising global temperatures and growing inequalities in access to public infrastructure in major cities. The movement's 10-point charter begins with the affirmation of "the right to swim," celebrating urban swimming culture and recognizing the historical significance of 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.
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, 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.
