Construction: The Latest Architecture and News

The Canadian Wood Council has announced the winners of the 39th annual Wood Design & Building Awards program. The awards program honors and recognizes the remarkable contributions of architects worldwide who excel in wood design and construction. This year, the program attracted a record 181 nominations from 25 different countries, and 24 winning projects were chosen from the excellent pool of submissions.

Starting from the first sketches of a project, it is essential that the project's design restrictions are well defined. This will guide the project, making it more suitable for its location, owners, and local conditions. Among common restrictions, keeping the project cost low is perhaps the most ubiquitous. We spoke with the VAGA team, an office based in São Paulo, about the challenges and possibilities that working with a tight budget imposes:

Pretentious as it may sound, we can say with certainty that bamboo is one of the most promising materials for the future of the construction industry. Neil Thomas, principal engineer at atelier one, says that if we were to design an ideal building material, it would look a lot like bamboo. This is because it grows very fast, is present in many countries around the world, has a highly efficient cross-section, and has impressive load-bearing strength. But beyond its structural use in its raw form, bamboo is also a material that allows a high level of processing and can be laminated for flooring, fixtures and, as we will see in this article, for Structural Engineered Bamboo (SEB) structures, which are very similar to Engineered Wood. We spoke with Luke D. Schuette, founder and CEO of ReNüTeq Solutions, LLC, a company in St. Louis, Missouri, that has been working with this structural material technology.

Everyone who has ever built anything—a model, a birdhouse, or small pieces of furniture—has a clear sense of the amount of things that can go wrong during the construction process. A screw that is impossible to tighten fully, a warped wooden board, an inattention or a miscalculation that can frustrate plans instantly. When we transport these small inconveniences to a building scale, with countless processes and many different people involved, we know how complex a work can become and how many things can get out of control, taking more and more time and requiring more and more resources to finish. And when we talk about a building that needs to float, be completely self-sufficient, and, after fulfilling its useful life, be completely reused—could you imagine the technical challenges of building something like this?

The aquatic environment has always fascinated dreamers and researchers. Around 1960, in the midst of the fierce space race of the Cold War, French explorer Jacques Cousteau developed equipment such as the Aqualung to unravel the depths of the sea, which remained as unexplored as outer space itself. He even stated that in 10 years we could occupy the seabed as “aquanauts” or “oceanautas,” where it would be possible to spend long periods extracting mineral resources and even growing food. Sixty years later, the seabed is still reserved for few, and mankind has been more concerned with plastic in the oceans and rising sea levels than colonizing the ocean floor. But being close to a body of water continues to attract most people. Whether out of interest or in response to risks of flooding and over-population, some have turned to utopian proposals and floating architecture, examples of which have been featured in the ArchDaily project archive. But what are the fundamental differences between building houses on land versus on water, and how do these buildings remain on the surface rather than sinking?

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.

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.

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.

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”?
