The construction industry is one of the largest in the world, and cement and concrete are literally the building blocks of its success. Evolving from prehistoric caves to today’s towering skyscrapers, concrete structures have and will continue to be vital components of modern civilization, providing long-lasting, reliable support for buildings, roads, bridges, tunnels and dams. So much so that concrete is the most consumed material on Earth, second only to water, while the steel used to reinforce it is by far the most commonly used metal. But this doesn’t come without high environmental costs: concrete accounts for 8% of global CO2 emissions, much of which come from the extraction and transportation of aggregate materials such as sand, gravel and crushed stone.
Add cabbage leaves, orange peels, onions, bananas and a few slices of pumpkin to get... cement. That's right, researchers from the University of Tokyo in Japan have developed a technique through which it is possible to produce cement from food waste. Besides being used in construction, the innovative initiative is edible as well. You can make boiled cement into a delicious meal by adjusting flavors, adding seasonings, and breaking it into pieces.

While the traditional image of the cabin is one of a rustic wooden home located far away from any trace of society, architects have been experimenting with these conventions alongside newer material and technological considerations to push the boundaries of the ‘cabin’ today. Whether it is by reimagining the aesthetics of the cabin, utilizing advanced fabrication techniques to modernize the rustic, or even reconfiguring the log cabin for the city setting, architects and designers have utterly transformed traditional cabin architecture for a more contemporary existence. Below, we consider 10 innovative cabins that achieve this transformation through experiments with different materials and construction technologies. While each explore different strategies and functions, many share similarities in their use of prefabrication systems, their dedication to sustainability, and their close attention to and optimization of specific material properties.

A 2022 United Nations report claims that the negative impacts of the climate crisis are mounting much faster than scientists predicted less than a decade ago. Rising greenhouse-gas emissions could soon outstrip the ability of many communities to adapt, and the consequences will continue to hit the world’s most vulnerable populations. As climate scientist Maarten van Aalst suggests, “Any further delay in global action on adaptation and mitigation will miss a brief and rapidly closing window of opportunity to secure a livable and sustainable future for all.” The data is clear: to protect our planet, we need to prevent a 1.5°C rise in global temperatures this century. To do so, the world must achieve a 45% reduction in global carbon emissions from 2010 levels to 2030, to then reach a net-zero state by 2050. It is evident, however, that we are on track to miss this goal by a substantial amount. The clock is ticking, and every industry should act fast (and drastically) to even dream of greener cities.
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.
When developing a project, an architect needs to deal with numerous decisions: Does the building correspond with the client's requirements? Can the contractors build it without problems? Are the costs what were initially expected? Does the project have a good relationship with its surroundings? How will it age? To figure all of this out, the professional must take into account several issues that will both influence each other and directly affect the final product. Among these, the chosen materials and constructive techniques play an essential role, as these elements are what give shape to the designer's vision and can influence factors such as the accessibility or the environmental impact of a building.
However, being well-versed in all the options, advantages and disadvantages of each decision is a herculean task that demands resources, research and time - factors that are usually scarce in our profession. Under the motto “What is good architecture”, we have compiled a series of articles that exemplify best practices in the use of constructive materials and techniques, seeking to cover as much ground as possible for all types of questions:
We have written a lot about the adaptive reuse of buildings and how this should become an even more important activity for architects in the future. Focusing on interiors, it consists of adapting spaces to new demands, promoting quality and comfort, and often incorporating new technologies into a space. Whether adding a new bedroom, organizing a home office, or transforming a historical building into an office, the architects' creativity allows them to create interesting environments without the need for demolishing. But one thing that tends to make designers scratch their heads in concern is how to include bathrooms and all the complication that it entails. This is because adding a simple toilet usually requires breaking slabs, walls, and floors, working with thick plumbing, and, above all, spending a lot of money and time. There is, however, the possibility of using a macerating pump system - a straightforward, affordable solution for creating a complete or half bathroom practically anywhere.
Blending in with its urban context or standing out to draw attention, a façade tells a building’s story. It is an expressive medium through which we engage with architecture, defining first impressions and setting the tone for the interior by experimenting with transparency, movement, texture and color, among other aesthetic possibilities. Of course, the envelope also plays a crucial functional role, acting as a protective barrier against extreme weather conditions and directly impacting light transmittance, energy efficiency and acoustic comfort. Architects therefore face an important challenge: to achieve a balance between an attractive look and performance. To do so, it is pivotal to specify the right materials during the design stage.
With the construction sector getting back into full swing and major upcoming projects being announced, a larger workforce is getting ready to take on these colossal works. Accordingly, on-site presence and inspections are critical and essential to creating good architecture and constitute significant learning instances for architects or engineers looking to build expertise. But despite all these new endeavors that promise new technologies, a more sustainable future, and better ways of living, one old issue prevails the presence of gender discrimination on the construction site.
Many urban planners predict that by 2050, more than 6 billion people will live in cities, and in places where building outwards isn't an option, the only way to keep up with the growing density is to build up. Building taller always comes with numerous challenges and also a not-so-subtle competition for architecture firms to have their name tied to the biggest buildings. Almost as fast as a building is named one of the tallest in the world, another one makes its way to the drawing board, a few years later taking the title. While the sky’s the limit, how does this impact the constructability of projects, and what feats of construction methods and materials have enabled us to build into the clouds?
Architecture is not simply building. Over 2,000 years ago, Roman architect Marcus Vitruvius Pollio defined two base realities in building: “Firmness” (Safety) and “Commodity” (Use) and then offered what turns building into architecture: “Delight” (Beauty).
“Firmness” has been recoined in this century as “Resilience”. After being unscathed in five hurricanes over thirty years, does this building have “Delight” beyond its “Firmness”? The property of “Commodity” is found in any design’s usefulness and fit: is this archive, in constant use, have “Delight” beyond its “Commodity”?
You may have heard about the use of bamboo in the temporary shelters created in humanitarian aid efforts after an earthquake, but bamboo can actually be very valuable in the construction of buildings that can withstand earthquakes. Why should we look towards bamboo as a temporary solution after a disaster when we could save lives by building with it in the first place? Bamboo is a great option for building homes and shelters in earthquake-prone regions, given that the structures are well designed, constructed, and maintained. From old traditional structures to modern builds, several examples from across the globe have proven themselves against the very forces of nature that have brought down concrete and brick buildings.

“We should admit nature as an immense multitude of forms, including each part of us, who are part of everything”, says Ailton Krenak, renowned indigenous leader, in his book Ideas to Postpone the End of the World. The culture of native peoples does not understand humanity and the environment as things that are separate or superior to each other, but rather as parts of a whole. Through this particular understanding of the universe, these peoples are led to a sensitive appropriation of the territory, with structuring beliefs that are also reflected in their architecture, raising the very concept of sustainability to another level, since nature is not seen as a resource to be used, it is thought of as part of the community.

Nearly to be completed and opened in 2023, MAD Architects reveals the construction details that made it possible for the Aranya "Cloud Center" to appear floating above the rolling landscape surrounding it. Located in Qinhuangdao, 160 miles away from the east of Beijing, China, the 2,500-square meters Center will be a public art space for the vibrant artistic seaside community that, from the outside, will mark the center of a sculptural landscape that MAD had conceptualized as a "white stone garden."
“Hope for Architecture” is the calling of Clay Chapman and described by him as “a building initiative to address the challenges of an uncertain future.” In truth, “Hope for Architecture” is a masonry and timber technology, reinvented and adapted from antiquity for this moment. Clay and his young family moved to Carleton Landing, Oklahoma fifteen years ago to fulfill a mission: creating a community and explore that technology.
Architecture is born from materials. Between structure, light, movement, and comfort, materials profoundly shape our experiences. But materials also change over time, new ones are created, and a wide range of assemblies and construction techniques are introduced. Increasingly, architects and designers are looking into the possibilities of composite materials made with natural elements.
In the field of design and construction, the question of gender is a point of conflict: who has the possibility of building? What are the alternatives for us architecture professionals? These are the questions that Taller General (re)think about. It is from these questions that Femingas, a participatory construction conference with a gender perspective, arose. These are manifested as an alternative to the construction of "mingas", days of joint work between the members of a community to achieve a common good.
Looking ahead to the future of our built environment, a one-size-fits-all approach simply won’t do. Issues like rising sea levels, temperatures, and water scarcity in urban communities need localized solutions that take into account questions of sustainability, culture, and public health. Having investigated vernacular infrastructure across indigenous communities for her book Lo-TEK. Design by Radical Indigenism, designer Julia Watson is an expert in local, nature-based technologies that are inherently adaptable and resilient. We talk to her about the future of our cities, building materials, and her latest project for Our Time on Earth – a five year, world-touring exhibition that just opened at London's Barbican Centre to investigate how radical, collaborative ideas for the way we live can get us to a much improved place by 2040.
