Ultimately, the pavilion's design reflects the Expo's theme, "Come Build the Future," embodying sustainability and reuse.
Lydia Kallipoliti is a recognized architect, author, and educator whose pioneering research has transformed the way architecture engages with the pressing challenges of sustainability, technology, and environmental politics. As an Associate Professor at Columbia University's Graduate School of Architecture, Planning, and Preservation (GSAPP), Kallipoliti's approach to architectural education encourages students to confront critical issues such as waste, reuse, and closed-loop systems. Her pedagogical philosophy empowers students to see design not only as an aesthetic or functional pursuit but as a powerful tool for addressing global ecological crises, urging them to think systemically and creatively about the future of the built environment.
In addition to her role in academia, Kallipoliti has authored influential works such as The Architecture of Closed Worlds and Histories of Ecological Design: an Unfinished Cyclopedia, which delve deeply into the relationship between architecture and environmental politics. Her research and writings have sparked discourse on methods for architects to reconsider traditional design paradigms and embrace sustainability as a core tenet of architectural practice.
Pavilions offer architects a unique opportunity to experiment, serving as compact spaces that push the boundaries of design and spatial concepts. Free from many conventional functional constraints, these structures allow for artistic expression and the testing of new technologies. Pavilions often act as living laboratories of architecture, positioned in public or cultural contexts. They transform their surroundings into interactive, memorable experiences, providing a stage for architects to showcase their most innovative ideas. In recent years, climate responsiveness has emerged as a crucial focus in pavilion design. By using temporary structures as a testing ground for more sustainable practices, architects can experiment with alternative materials and environmentally conscious approaches that address the climate crisis.
Foster + Partners, in collaboration with the Maldives Fund Management Corporation (MFMC), has unveiled the masterplan for Gaafaru, an inhabited island in the Kaafu Atoll of the Maldives. This project is designed to ensure a sustainable and resilient future for the island by addressing the critical challenges posed by climate change, rising sea levels, and social inequalities. At the heart of this plan are six guiding principles that aim to balance environmental protection with community prosperity, creating a model of future-proof island development.

Throughout history, it has become clear that the key to long-lasting and sustainable projects is to lay solid foundations. Our society is headed towards a more urban future in which the density of metropolises will be ever greater. That is why this more urban tomorrow requires modern urban planning capable of building innovative, sustainable and flexible structures. Because the only way to make our society live better is to build better.
With expanding urban populations and evolving consumption patterns, cities are faced with challenges pertaining to waste management. Traditional approaches centered on collection and disposal currently seem inadequate in the face of serious environmental concerns and resource scarcity. Waste management has become a focused topic to address, being introduced as a key strategy towards circular economies. The Zero Waste concept hopes to transform the way cities manage urban waste and build supportive cultures around it.
Space exploration isn’t merely a testament to human ambition or a quest for new territories and resources. Our ventures beyond Earth’s atmosphere are driven by a deeper purpose: to understand better our place in the cosmos and to pioneer innovations that can transform life on our home planet.
Following a competition, Zaha Hadid Architects (ZHA), in collaboration with JLand Group Sdn Bhd (JLG), have been chosen to design Discovery City in Johor, Malaysia. The disctrict is expected to be to be a visionary 582-acre mixed-use precinct within the expansive Ibrahim Technoloplis in Johor. As ZHA’s inaugural project in Malaysia, Discovery City aims to boast a blend of innovative design and sustainability, blending with the region’s landscapes.
The Kingdom of the Netherlands's pavilion, presented at the Expo 2025 Osaka, Kansai, Japan, features the theme, "Common Ground: Creating a New Dawn Together," emphasizing the Netherlands' dedication to fostering mutual understanding to address global challenges. Designed by RAU Architects, the pavilion's circular design features a prominent illuminated sphere at its center, symbolizing a new era of unlimited clean energy, akin to a "man-made sun" signaling a future powered by sustainable resources.
Evolving urban conditions call for an evolving builtscape, and retrofits have been a key mechanism to allow buildings to adapt and respond to new needs. Amidst global environmental concerns, climate retrofits have become a popular strategy to upgrade buildings based on improved operational efficiency. Global decarbonization plans have even called for city-wide retrofits, such as in the case of London, to meet civic goals. While such upgrades significantly reduce energy consumption, they often come with a hidden cost - embodied carbon in retrofit materials and the potential for future waste.
Today, interconnected and fast-paced lifestyles, future mobility trends and constant material innovation puts pressure on a slow-moving building industry. How can architecture keep up with this trend? Following dynamic and nomadic lifestyles, architects must explore new structural systems that should be able to reach multiple locations, as well as be adaptable and reusable in the future. By applying revolutionary technology for circular, scalable components and carbon-negative buildings, UrbanBeta –a spatial innovation studio designing strategies, building concepts, predictive tools and platforms for creating transformative spaces– has developed BetaPort, a robotic construction system powered by artificial intelligence and automation.
Based on the principles of a circular economy, Urban Beta and BetaPort create a sustainable construction plan, ready to grow and change over time. The studio conceives sustainable on-demand architecture systems for flexible buildings based on a kit of parts.

In contemporary architecture, recycling has evolved from a desirable to an unavoidable necessity. This change is mainly due to the growing climate crisis, accentuated by the constant presence of waste (for which no use has been found beyond the initial one).
This approach has stimulated the creation of innovative materials to reuse waste in various contexts. A notable example is the case of woven flooring and rugs, where Bolon took a step forward in 1949 by transforming textile waste into stylish products. Since then, they have continued to innovate in materials, fusing the traditional flooring branch with sustainable creative design.

For a long time, the construction industry has followed a linear process - extract raw materials, build structures, demolish them, and then dispose of the garbage in landfills. This approach has serious negative effects on the environment and society and is inherently unsustainable. Reconsidering traditional methods and workflows requires support from all stakeholders and a sense of urgency proclaimed by authorities. In the United States, city organizations have begun to implement new policies to keep construction waste out of landfills and support circular practices. Several cities like Seattle and Pittsburgh, have started implementing deconstruction ordinances that require older buildings to be carefully deconstructed rather than demolished. How might their key provisions influence circular practices in the country?
The principles of the circular economy have been most influential and applicable to the construction industry. Emphasizing the efficient use of resources, models around reuse and recycling of components and materials are increasingly being pioneered by global architecture practices. The concept of "design for disassembly" has emerged as an innovative approach especially in the case of building facades. Striking a balance between the demands for new infrastructure and the transition towards sustainability requires a review of traditional facade design throughout its lifecycle.

“Landscape architects have started conversations about embodied carbon. There is a realization that we can no longer ignore the grey parts,” said Stephanie Carlisle, Senior Researcher, Carbon Leadership Forum and the University of Washington, during the first in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee.
The grey parts are concrete, steel, and other manufactured products in projects. And the conversations happening are laying the foundation for a shift away from using these materials. The landscape architect climate leaders driving these conversations are offering practical ways to decarbonize projects and specify low-carbon materials.
