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.
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?

BIG has partnered with experimental clothing brand Vollebak to create the vision for a self-sufficient off-grid island in Nova Scotia, Canada. The 11-acre Vollebak Island will receive several pavilions built of natural and innovative materials such as seaweed, hempcrete, and 3D-printed concrete, all powered by carbon-neutral energy. The island, located in Jeddore Harbor, one quarter off the Nova Scotia mainland, will be auctioned via Sotheby’s Concierge Auctions beginning June 8. Bidders will vie for the chance to own the island and to be granted exclusive rights to the design vision, including the planning permission for those designs.
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.
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.
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.
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.
The history of architects designing resorts is intertwined with the development of the hospitality industry and the concept of leisure travel. The origins can be traced back to ancient times when the Romans built luxurious villas and bathhouses as retreats for the wealthy. However, the modern notion of resorts emerged during the 19th century with industrialization and the growing middle class seeking recreational experiences.
At a very high standard of luxury, resort hotels provide an immersive and rejuvenating vacation experience. These resorts are frequently rooted in beautiful landscapes in remote locations, often containing full-service accommodations, offering escapism and complete disconnection. Architects have continued to shape the resort landscape in recent decades with their designs. Sustainability and integration with natural surroundings have gained importance as architects strive to create environmentally conscious and immersive resort experiences.
As world governments grapple with environmental crises, the construction industry rushes to reevaluate sustainable design and develop new ways of measuring its efficiency. Consequently, green building certification systems (GBCS) started gaining traction in the 20th century to evaluate and promote sustainable construction practices. The Global South faces distinctive challenges in building sustainable cities. Its developing nations demand an exclusive approach to designing an appropriate, economical, and inspiring architecture for their promising futures.
Solid wood, which has been used since prehistoric times and is still highly valued today, is extracted directly from trees without undergoing any lamination, pressing, or gluing processes. While it remains a universally used material in architecture, its widespread use has led to an increased demand and less efficient resource management. Therefore, solutions are being sought to optimize its use in production processes and reduce its consumption without losing its capabilities and characteristic beauty. To address issues such as warping, aging, and high environmental costs associated with solid wood, materials like Technowood have been developed. Combining technology and super-strength composites with natural wood veneers, Technowood maintains the beauty and characteristics of solid wood, but with greater durability and a sustainable approach, making it a suitable alternative.

The concept of sustainability emerged at the United Nations Conference on the Human Environment (UNCHE) in Stockholm in 1972 and was coined by Norwegian Gro Brundtland in the report "Our Common Future" (1987). According to this definition, the sustainable use of natural resources should "meet the needs of the present generation without compromising the ability of future generations to meet their own needs." However, despite the urgency of the concept and the constant evolution it has undergone over time, its application is often restricted to the controlled use of natural resources and the preservation of wildlife. In other words, it treats the situation from the perspective of "man versus nature," as a dichotomous view, with the loss of a holistic perspective.
As part of the Circlewood consortium, OMA’s David Gianotten and Michel den Otter have developed a modular system to build schools that can adapt and transform throughout their lifecycle. The system was selected by the City of Amsterdam to be employed to build multiple schools in the coming ten years, as part of the Innovation Partnership School Buildings program. The citywide initiative aims to build nine to thirty “high-quality, flexible, and sustainable” schools as a way to contribute to the city’s goal of becoming fully circular by 2050.

Help an essential global industry decarbonise
The Innovandi Open Challenge is a global programme which brings together tech start-ups and the world’s leading cement and concrete companies to help accelerate the next wave of innovations to achieve our net zero mission.
The Global Cement and Concrete Association (GCCA) and its members understand the key role that innovation will play in unlocking a net zero future for concrete –the world’s most used material after water– which is essential to building the sustainable world of tomorrow.
Dismantling the system of slave and child labor in the architecture and construction industry does not seem like a simple task, especially on a global scale. However, this is precisely the mission of the Design for Freedom (DFF) initiative, created by CEO and founder of the Grace Farms Foundation, Sharon Prince, along with Bill Menking, professor and editor-in-chief of The Architect's Newspaper.
Through events and freely available tools, Design for Freedom seeks to "raise awareness and inspire responses to halt forced labor in the construction materials supply chain," offering paths to ensure transparency and ethics in the architectural production process.
Following findings from a study published in the Nature Ecology & Evolution journal this April, it has become public knowledge that the phenomenon dubbed the Great Pacific Garbage Patch (an area of 620,000 square miles between California and Hawaii) is serving as host to an entire coastal ecosystem. Marine wildlife is using the massive area compiled of human plastic waste as a floating habitat, and scientists are shocked at the number of species that have managed to establish life in this otherwise hostile environment.
The news once again brings into sharp focus not only pressing issues of climate change and ocean pollution but also the question of environmentally-induced migration, even at a microbial level. Architecture is moving into more and more experimental realms when it comes to considering locations for the communities of our future – and rising sea levels have promoted water to the top of the list. But these deliberations are not as recent as one might think: floating cities have been around for centuries and individual homes on water are common in areas of Benin, Peru or Iraq, among others.
