Finding effective and valuable solutions for agricultural waste management has been an inspiring challenge for researchers. By-products from monocultures, such as residues from soybean production, corn cobs, straw, sunflower seeds, and cellulose, are often destined for soil composting, used as animal feed, or even converted into energy in order to reduce waste and mitigate the environmental impacts associated with agricultural activities. Sugarcane production, for example, generates a significant amount of waste, totaling about 600 million tons of bagasse fiber waste from an annual production of two billion tons of sugarcane. This waste has a promising potential to replace energy-intensive building systems, such as concrete and brick, by providing building materials that combine sustainability and structural efficiency.
With this perspective in mind, the University of East London (UEL), in partnership with Grimshaw Architects and manufacturer Tate & Lyle Sugar, has developed an innovative building material called Sugarcrete™. The aim of the project is to explore sustainable building solutions by recycling biological waste from sugarcane, which in turn reduces carbon emissions in the construction industry – all while prioritizing social and environmental sustainability during the production and implementation of these building materials.
Harnessing the power of moldless manufacturing through large-scale robotic 3D printing, research at ETH Zürich in collaboration with FenX AG delves into the use of cement-free mineral foam made from recycled waste. The objective is to build wall systems that are monolithic, lightweight, and immediately insulated, minimizing material use, labor requirements, and associated costs.
Professionals in the AEC industry are well aware of the issues that grapple the built environment. That the construction industry is the largest consumer of materials and is responsible for 40% of all carbon emissions is a commonplace fact. Construction work is also a large waste generator and could greatly benefit from circular design principles. Almost three-quarters of all construction projects tend to be over budget, and nearly half of the spending on buildings goes into the overheads. In a fast-paced world with multi-faceted challenges, technology, and digitization seek to deliver significant solutions.
“Can you help me design my residential tower? It's 30 stories and located in Brooklyn, New York.” ChatGPT’s response may be surprising. Given that the bot has no architectural experience, and is certainly not a licensed architect, it was quick to rattle off a list of considerations for my building. Zoning codes, floor plan functionality, building codes, materiality, structural design, amenity spaces, and sustainable measures were just a few of the topics ChatGPT shared information about.

Nowadays, the understanding of our building culture and the application of local construction methods may seem like a distant and obsolete concept given the role of industrialization and globalization in the construction industry. We can now obtain almost any material from around the globe just by searching the internet for a distributor in our region. But this practice has important implications for our society, from the loss of architectural identity to environmental costs related to high CO₂ emissions associated with the processes of extraction, manufacturing, transportation, and disposal of these materials.
The increasing global need to reduce our carbon emissions and use materials in more efficient ways has led us to research and learn about the origin of our region's resources, eventually leading to better understanding their applications within a circular economy approach. But why not look right under our feet? Soil is one of the most common materials on the planet, and when it is locally sourced, it does not generate considerable amounts of embodied CO₂. It seems that after industrialization, we have forgotten that building with earth was for many years a viable construction method for our ancestors in different parts of the world. We spoke with Nicolas Coeckelberghs, one of the four founders of BC Materials, a worker cooperative based in Brussels that has been working with earth, rediscovering its use, and sharing its knowledge on a global scale while working with a local conscience.

Do you remember seeing images of designers leaning over large sheets of paper, usually in spaces that resemble warehouses, concentrating on their own technical drawings? While some may view these images with nostalgia for a simpler time as a sign of working passionately in the architecture, engineering and construction industry, many others might shudder at the thought of doing an entire project with an India ink pen, and especially without the convenience of the Undo tool (CTRL+ Z or command + Z). From the first CAD programs to the powerful modeling programs we have today, computing technology has radically transformed the landscape of AECO offices. In the past, integrating multiple designs required overlapping sheets of tracing paper; but today, we have a variety of software that produce files with numerous extensions, saved versions, sizes, and which often require powerful machines to run. With the growing adoption of remote and hybrid work in AEC organizations, implementing the right computer systems can be a major challenge.
Fueled by pressing issues such as the climate crisis, population density and rapid urbanization, the built environment has become increasingly complex. Architecture and design professionals are faced with a challenging, yet fundamental task: to translate society’s ever-evolving needs into tangible and future-oriented solutions. In pursuit of this goal, they must embrace the countless tools, materials and technologies emerging every day in the construction field –from AI to virtual reality software and smart home systems. After all, to remain at the forefront in an industry where change is the norm, the ability to adapt and evolve is crucial for success.

Buckminster Fuller's obsession with geodesic shapes placed them in architectural history. The spherical appearance and the complex structural framework gained different appropriations and scales over the years, one of the most iconic works being the Montreal Biosphere, the US pavilion for the 1967 World Expo, designed by him. These structures emerged from his interests in material efficiency, structural integrity and modularity. Back in the 60s, he understood these features as essential for a sustainable and easily replicable intervention
Animals measure distances and weight for their survival. On the other hand, stemming from their need to communicate to live in society, humans created languages and, later, established the standards of measuring. Whether for moving around, portioning food, making tools, or calculating the weight of objects and animals, measurement standards arise from this need that was already present in human activities in the age of chipped stone and has been with us ever since. Nowadays, most of the world's population uses meters and centimeters to measure distances. These standards come from the need to establish comparisons that allow trade between peoples and also from political and social disputes.
“Our planet is choking in plastic,” states the United Nations. While the man-made material has many valuable uses, our addiction to single-use plastic products has led to severe economic, health and environmental issues. Roughly one million plastic bottles are purchased every minute, and five trillion plastic bags are used every year worldwide –used just once, then thrown away. Plastics and microplastics have found their way into every corner of our natural environment, from the peaks of the highest mountains to the depths of the deepest oceans. So much so, that they have become part of the Earth’s fossil record and created an entirely new marine microbial habitat known as the “plastisphere.”
Can you imagine being able to prototype a piece of furniture at the touch of a button and testing it in just a few hours? This might become a common practice sooner than we may think. Fueled by material innovation, automation and cutting-edge technology, a new era in home decor is emerging; one where 3D printing opens up a world of creative possibilities that transcend the bounds of traditional design. Yes, furniture is still mass-produced using conventional methods –molding, cutting, bending–, but 3D printing continues to disrupt the industry. As the revolutionary technology evolves and becomes more accessible, it has unleashed an unparalleled level of creative expression and efficiency. The concept is simple: a digital design is created using 3D modeling software and then printed, layer by layer, in the form of a physical object, bringing complex geometries to life. It’s a whole new kind of digital craftsmanship.
Through shapes, colors, and the elements on their facades, many architects have sought to bring a sense of movement to works that are otherwise physically static. Santiago Calatrava, Jean Nouvel, and Frank Gehry are only a few of the masters who managed to provide a dynamic effect to motionless structures, highlighting the work in context using formal strategies borrowed from the plastic arts. In other cases, however, architects have also opted for physically kinetic structures that could bring a unique aesthetic or functional dimension to the work.
As the world slowly adjusts to the "new normal," so too does the architecture industry. Data related to market size and workloads shows that the profession continued to grow even after the pandemic struck. Other statistics show how architects are starting to be hit by the present crisis – such as the fall in full-time work and rising unemployment. While these statistics could take one down a road of despair (or enthusiasm), there is more to the numbers: Mobility, digital and managerial competencies are framing the profession in the 2020's. Not only as data for the sector to approach the market and retain talent but also as strategies in the face of crises and technologies to come.

The promise of the metaverse is proving to be a fertile ground for research and experimentation for architects. This new realm is currently undefined, consisting of many narratives, explorations, and opportunities for architects and designers to shape a new type of environment. Generative engines, such as AI image-generators, are contributing to the feeling of open possibilities. While they are not yet part of the standard practice, they bring the promise of a shift in the production of architecture. Conceptual projects such as the ones presented in this list serve little to no external purpose. Still, they are essential in conducting an understanding of the possibilities of the new technologies which are likely to have a significant effect on the profession.
This week's curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community that experiment with a new medium and integrate novel technologies. From abstract buildings created to be experienced through virtual reality in the metaverse to investigations into the ability of AI image generator engines to develop innovative architectural expressions and even research into planimetry, the following projects are pushing the boundary of what architecture could look like in the new age of technological developments.
The promise of the metaverse, this new type of three-dimensional and immersive digital space, is proving to become more and more appealing to architects eager to explore the new realm of virtual creations. As it currently stands, the metaverse does not have a singular definition but is composed of many narratives and explorations. This unknown land is however fruitful ground for architects, who have to opportunity to shape not only the new environment but also the experiences of future users. The SOLIDS project represents one response to these conditions. Developed by FAR, an architect and engineer working with digital environments, SOLIDS uses a generative process to design unique, metaverse-compatible buildings.
The new technologies of the digital world caused changes in architecture and urbanism. New materials, new construction techniques, and new ways of manufacturing and building have changed how we design and think about construction. Besides, these technologies reveal possibilities of interaction between society and architecture, transforming the understanding of architecture and its purpose.
It is a great privilege to amplify the voice of architects and other built environment professionals. It is also an enormous challenge as it requires a lot of investigation and time from our content team. However, the effort is gratifying. It puts us in contact with some of the most prominent talents in our field who have been discussing subjects such as cities, metaverse, community, environment, democracy, sustainability, building technology and interiors, to mention just a few.
