Almost two decades ago, in the downtown corridor of Columbus, Ohio, the century-old landmarked Lazarus Building underwent an extensive renovation to save the department store and restore it to its former glory. Sixty million dollars went into its restoration and transformation into a retail and office complex. During the construction, workers recycled nearly 5,000 pounds of steel, 2,000 pounds of concrete, and significant amounts of carpeting, ceiling tiles, and various wood- keeping 22,000 pounds of debris out of Ohio’s landfills. They also saved more than $25 million dollars by implementing this rigorous recycling process.
Timber is a natural, renewable material, easy to fabricate, and with low-carbon emissions. As a construction material, however, when put under enough directional force along its grain, sawn timber is structurally unstable, so deemed unsuitable under higher loads. In comparison, the manufacture of cross-laminated timber (CLT) involves simply gluing multiple layers of timber together at right angles. By crossing the direction of the grains, CLT achieves a far higher level of structural rigidity along both axes. CLT boards start with a minimum of three layers but can be strengthened further with the addition of more. Simply put, due to the complex physics involved in the perpendicular lamination, the strength of CLT board is similar to that of reinforced concrete, and has proven performance under seismic forces.
So what’s new? Wood’s been around for long enough now, and we’ve been using it as a building material for centuries. Surely this isn’t the first time someone’s realized it gets stronger the more you use it? Well… as you’d expect, the changing popularity of cross-laminated timber in construction does coincide with a greater understanding and focus on environmental causes, but the relationship hasn’t always been positive.
Architectural competitions play a crucial role in developing the architectural profession and in advancing the quality of the built environment. They are also an opportunity for architects to showcase their creativity and experiment with innovative or unexpected architectural solutions, be it for real or imagines contexts. This week's curated selection of Best Unbuilt Architecture highlights different competition-winning designs submitted by the ArchDaily Community.
From a spa and wellness center seamlessly integrated into the mountainous landscape of Austria to a refurbished city center that creates opportunities for social interaction in one of Bulgaria’s largest pedestrian city centers, the round-up spans various programs, scales, and attitudes toward the built or natural environment. The selected projects represent explorations in various design solutions, materials, and construction methods. They also showcase the broadness of possible responses ignited by site-specific conditions, from the volcanic landscape of Iceland, to the picturesque hills of the Kerala region in India or the lively central plaza in one of Israel’s largest cities.
As Venice Architecture Biennale presents its 18th edition titled "The Laboratory of the Future", it centers on Africa as a place of exploration that will offer a template for solutions to the world. According to its curator Lesley Lokko, the Biennale explores entrenched concepts such as climate, land rights, decolonization, and cultures. It challenges us to question how Africa's history can be a radical tool for imagination and reminds us of Stephen Covey's statement: “Live out of your imagination, not just your history.” The biennale's title is probably the most ambitious question in years. It forces us to revisit all boundaries of the continent's historical societies, explore the influence of imposed colonial borders on them, and examine the dual identities they gave birth to. We must consider how these identities can be instruments of creativity, and, more importantly, recognize that every African society has a unique point of view. This viewpoint yearns for cross-cultural collaboration as a powerful tool for imagination.
Architecture is a continually evolving form of human expression influenced by cultural and contextual factors. While many of the problems we face today aren't directly linked to architecture, it has the ability to provide or facilitate solutions to these challenges. This has been evident throughout history, as societal issues have played a significant role in shaping our built environments. For instance, during the Victorian era, the infamous "Great Stink" led to the modernization of London's drainage system and urban layout. Similarly, the 2008 recession gave rise to the sharing economy and coworking spaces. Nowadays, the climate crisis is transforming the way we conceive architecture, seeking to reduce the carbon footprint of buildings and cities to achieve the Paris Agreement objectives. Given this backdrop, what challenges should we expect in the future?

Climate issues have been the main topic of discussions about the future of cities, but they are certainly not new. The warning about human irreversibility on the planet has been part of scientific discourse since the 1980s. Faced with increasingly frequent environmental urgencies, Donna Haraway, in her book Staying with the Trouble: Making Kin in the Chthulucene, suggests a change in attitude on the part of humans to ensure not only partial environmental recovery but the species' survival.
In increasingly denser urban environments, there is a new-found interest in underused spaces as opportunities for further development. Representing up to 25% of cities' land area, rooftops are among the most exciting spatial resources. From sustainable infrastructure and urban farming to social spaces and cultural venues, the article looks into the potential of creating a multi-layered city through the activation of urban rooftops.
Change is hard, especially when it’s being forced upon you. But change can often be a good thing, too. Forcing growth and refreshing vitality. Those first few months after a child flies the nest are the hardest to bear when having to get to grips with the new normal of a quiet, lonely household.
Just as many soon-to-be-parents hit a sudden period of ‘nesting’ before the stork’s arrival, those on the other end of the child-rearing timeline experience an opposing feeling of grief when their home with a child reverts back to one without. Feelings of emptiness, loneliness, and a lack of purpose are joined by anxiety for them and their new life, and the loss of parental identity.
When it comes to buildings, there are several factors that contribute to creating something truly luxurious: attention to detail, use of premium, high-quality materials, and unique designs. Lately, the environmental impact of building decisions has also entered heavily into this equation, and the development of a luxury project requires all steps and products to take sustainability into account. At One Za'abeel, the new addition to the Dubai skyline, the careful choice of all solutions, manufacturers and surfaces had a direct influence on the final look and atmosphere of the building, which aims to be an urban landmark and raise the standard of buildings in the UAE.

From Costa Rica, architect Bruno Stagno not only reflects on how responses to the environment can be the main basis for inspiration and identity in architecture but also proposes going a little further, with contemporary tropical architecture for an entire latitude.
What happens when these limits are extended? What happens when these motivations escape outside of the tropical context? Bruno Stagno presents here the project "A Mangrove for Berlin", his participation in the 1995 competition for the Reconstruction of the Berlin Academy of Architecture, "Berliner Bauakademie", an emblematic work of the architect Friedrich Schinkel.
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 by-products, totaling about 600 million tons of bagasse fiber waste from an annual production of two billion tons of sugarcane. This by-product 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 by-products 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.

In today’s challenging climate for business, companies with a long and distinguished heritage have an advantage over younger enterprises as they can draw on decades of experience in overcoming market fluctuations. In the design industry, knowledge passed down over generations can be vital, as companies are required to adapt to shifts in consumer behavior or the latest revolutionary technologies. These established businesses are often able to thrive during difficult times by developing products that balance innovation with tradition and transcend trends to instead deliver lasting success.

Kitchens encapsulate the essence of culture, acting as dynamic museums that preserve age-old recipes, processes, and traditions. Influenced by ethnic practices and culinary customs, kitchen architecture varies greatly across continents. In this context, kitchens transcend their domestic role and become insightful manifestations of cultural, societal, and regional factors. They not only serve as functional spaces for cooking and meal preparation but also stand as reflections of the rich tapestry of culture and lifestyles embraced by the individuals who inhabit them.
When François Lévy was asked to design a country home on a substantial piece of land, he immediately faced an issue: locating the building in a spot which required as little re-grading as possible while being able to reap the benefits of solar energy. The most desirable location —given site access and a range of mature oaks— would have left the building sitting slightly out of grade. And, if he had chosen the most obvious building orientation (long and narrow with broad elevations facing north and south), part of it would jut out of the ground and some crucial trees would be lost.
Vernacular architecture is a complex concept that has different meanings depending on where we are, and it is present in various architectural typologies. It is connected to its roots and place of origin, elements that define many of its characteristics based on specific aspects such as culture, climate, topography, vegetation, and the availability of materials and resources in each region. Its constructions are also often linked to traditional building techniques from each place. These techniques were developed by populations in a broader historical context based on available resources.
In this second feature, to learn more about the science panel on design for Climate Adaptation we met with Billie Faircloth, Partner and Research Director at KieranTimberlake, Adjunct Professor at the University of Pennsylvania, and Maibritt Pedersen Zari, Associate Professor at the School of Future Environments, Auckland University of Technology.

This Earth Day, U.S. Vice President Kamala Harris highlighted the many benefits of nature-based solutions and recognized the important role of landscape architects in this work. At the University of Miami, she also announced $562 million in funding for coastal resilience projects, supporting 149 projects in 30 states, through the Climate-Ready Coasts Initiative of the National Oceanic and Atmospheric Administration (NOAA). Vice President Harris’ remarks build on the Biden-Harris administration’s support for planning and designing with ecological systems in an equitable way.
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.
Currently at 103 million, the number of people forcibly displaced from their homes is continuously growing. Many seek shelter in settlements that are meant to be temporary, but where displaced people end up living years, even decades.
The Norman Foster Foundation and Holcim, global leader in sustainable building solutions, came together to form a response to this problem based on two firm beliefs: everyone has the right to a home, and everyone should have access to sustainable building.
Architecture involves mobilizing several aspects of the environment where the building is located: the socio-cultural, political and economic context, aesthetics, legislation, and functionality. Functionality includes use efficiency, occupancy, and comfort. Laurent Troost's work has shown the articulation between these various factors, with particular attention to comfort, especially thermal comfort. His projects prioritize natural ventilation over artificial air conditioning, which has become almost mandatory in current city models.
Environmental issues urgency and increasing temperatures on the planet are nothing new. There are many factors contributing to environmental degradation. However, two can be viewed as representative of critical points in the current world system: plastic and waste disposal, better known as garbage.
The environmental crisis cannot be attributed solely to these two examples. They are used here as examples to mobilize issues involving multiple agents, materials, and diverse methods. These issues lead to devastating consequences, increasingly irreversible.
Within the realm of commercial architecture, the design of spatiality can adopt multiple approaches, conceiving proposals that achieve a balance between aesthetics and functionality. Taking into consideration that various cultural variables, social tensions, and economic interests are involved, the construction of these spaces directly involves the interaction between users, brands, and their products, participating in the experience on-site from colors and materials to lighting, climate control, sounds, aromas, and more.
The largest exhibition of Norman Foster’s work to date, hosted by the Centre Pompidou, explores six decades of the architect’s illustrious career through a host of revealing sketchbooks, drawings, images, original models, and videos. The exhibition was designed by Norman Foster and executed with Foster + Partners and the Norman Foster Foundation. A custom-made series of modular display cases was designed by Norman Foster and a team from the Norman Foster Foundation and engineered by Goppion, world leader in the manufacture and installation of museum display cases, to display the architect’s sketchbooks and transparencies.
Wood is the concrete of the future. As timber construction becomes increasingly popular, you have probably heard this phrase. However, we are not talking about traditional construction techniques using timber, but rather about this well-known material combined with cutting-edge technology.
