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.
LAVA Architects has just revealed their design for The German Pavilion at Expo 2025 Osaka. Highlighting the theme of the circular economy, the pavilion is titled “Wa! Doitsu,” translating to “Wow! Germany.” Conveying enthusiasm, The Pavilion explores concepts around circularity, showcasing the “terminological culmination of the sustainability discussion.” Focusing on returning all consumable goods to the cycle of the economy, achieving zero waste, and minimizing resource consumption, the theme is visible throughout the entire design.
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 2020, in the midst of the first wave of lockdowns due to the pandemic, the municipality of Amsterdam announced its strategy for recovering from this crisis by embracing the concept of the “Doughnut Economy.” The model is developed by British economist Kate Raworth and popularized through her book, “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist”, released in 2017. Here, she argues that the true purpose of economics does not have to equal growth. Instead, the aim is to find a sweet spot, a way to balance the need to provide everyone with what they need to live a good life, a “social foundation” while limiting our impact on the environment, “the environmental ceiling.” With the help of Raworth, Amsterdam has downscaled this approach to the size of a city. The model is now used to inform city-wide strategies and developments in support of this overarching idea: providing a good quality of life for all without putting additional pressure on the planet. Other cities are following this example.

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.

Born in Brazil and educated in Paraguay, Gloria Cabral is an architect who early on learned that home can be many places—or none at all. Guided by a comprehensive understanding of the geography, culture, and social conditions of the places she designs, she has left her mark on buildings and artistic installations constructed in various locations, from Assumption to Venice.
Besides her interest in the specificities of the places where she operates, Gloria focuses on resource economy and material reuse — a trending theme that Gloria has championed for over fifteen years. We had the opportunity to speak with the architect about her experiences in Paraguay and Brazil, some of her works involving recycled brick, and her insights into architecture and sustainability.
A vital aspect of a circular economy lies in shifting our view of waste. Labeling an item "waste" implies voiding its value and ending its useful role in a traditionally linear economy. While the item might be out of sight and out of mind, its life continues in the landfill. This shift in perspective regarding waste means opening our minds to the opportunity that the abundance of junk presents. These designers and architects have managed to not only effectively reclaim discarded objects but also to make them look precious, imbuing them with new meaning and value through their careful curation.
The practice of upcycling –present in a variety of industries from fashion to construction– not only revitalizes discarded items, adding new values and functions, but also contributes to turning them into valuable resources. Adopting the spirit of the circular economy by harnessing agricultural waste such as corn cobs, rice straw, and sugar cane bagasse for building materials marks a fundamental shift towards sustainable practices, promoting a closed-loop system that minimizes waste and optimizes resource efficiency.
CornWall®, developed by StoneCycling, is a pioneering innovation in this regard. Inspired by the need to shift to a bio-based economy, it incorporates a transformative solution that addresses the pressing concerns of the construction industry's environmental impact. It is a wall-finishing material made from plant biomass, obtained mainly from the cores of regionally sourced corn cobs. This organic waste is widely available and is usually destined for fermentation, burning as biomass, or becoming simple organic waste. We spoke to Ward Massa from StoneCycling to better understand this material.
Buildings that are designed to layer stories and memories, evoke a sense of aspiration, define cultural narratives, and build a national identity will always be important in all societies. When buildings have this power to shape communities, make an impact on a city’s image, and change the course of socio-economic growth, then they can be identified as iconic. Though the term “iconic” is subjective, it is one that pushes the boundaries of architecture in any context. It calls for spatial originality, proposes innovative material technology, and necessitates a radical socio-economic investment to be realized.
However, since the economies of developing countries in the global south cannot meet the requirements of these architectural structures, is there a more suitable socio-economic model for monumental structures in this context? Can the incremental principles of small adaptable changes and growth be applied to the finite iconic aspiration of this architecture?

Architecture is a transdisciplinary field. It incorporates principles and knowledge from several other disciplines to ensure a built structure functions as intended. This fundamentally involves considering the context in which a building is placed, including its immediate surroundings, such as neighboring structures, local biodiversity, and climate. Essentially, architecture only exists within a particular context. When we expand this context to a broader scale, it becomes what we commonly refer to as the "environment."
Irene Roca’s “Appropriating the grid” project is born out of the contemporary ruins of our current construction processes. An exploration of the waste that is generated and the legal complexities of discarding this waste awakened a sense of urgency and creativity in the architect, resulting in a collection that molds and re-formulates construction waste into versatile interior design objects.
