Josep Ferrando is an architect based in Barcelona. He is the Dean of the La Salle Higher Technical School of Architecture (ETSALS), as well as Director of the Obert d'Arquitectura Center of Barcelona and of the Department of Culture of the College of Architects of Catalonia (COAC). Combining his academic career and his frequent lectures, his office develops projects that explore different scales and materials, experimenting with constructive systems and innovative solutions. We talked with him about the importance of materials in architecture, and about the synergies he finds between practice and teaching.

It is difficult to find someone who never played LEGO as a child. What if, like LEGO's, we thought of buildings as great assembling games? U-Build is a modular wooden construction system developed by Studio Bark to be easy to build, pleasant to inhabit, and simple to deconstruct at the end of its useful life. The system removes many of the difficulties associated with traditional construction, enabling individuals and communities to build their own homes and buildings. The system uses precision CNC machining to create a kit of parts, allowing the structure of the building to be assembled by people with limited skills and experience, using only simple hand tools.

The construction industry is known to be one of the most polluting industries on the planet, but we often find it difficult to associate the role of the architect and urban planner with this industry, thus avoiding the responsibility of being involved in one of the most harmful production chains in the world. Therefore, it is imperative to emphasize the importance of questioning not only the materials used in the projects but also the manufacturing systems involved.

Façade is one of the most important factors in certain building types, that can completely transform the occupant experience and the energy performance of the building. The Whole Building Design Guide showcases that the facade can have up to 40% impact on the total energy use of the building. In addition to the energy use, the facades also significantly impact the occupant productivity withing a building and, of course, the appearance of the building. There are many factors that go into creating a high-performance façade. In this article, we outline the top 5 things a design team should consider.

As our cities densify and building types become more and more mixed-use, we tend to spend a lot of time in noisy environments. When we think about acoustic comfort, we rarely think of places like restaurants, venues, and big offices; places with a lot of people, machinery, and background noise. The quality of sound can entirely change the experience of people in an interior space, and improving the space's acoustic quality relies on treating all surfaces, from walls to ceilings, and flooring. In this article, we will present a variety of solutions for ceilings, flooring, and walls, their different combinations, and a simple guide of how to apply them correctly in public spaces without compromising the aesthetic of the interior.

It is a common misconception that bunk beds - which are sleeping spaces elevated above floor-level - are used exclusively for the bedrooms of children and teens. While bunk beds are a great solution for younger kids and older kids alike, the practical aspect of bunk beds which gives ample sleeping space while saving on floor space, makes them great for a variety of purposes and applications. With a rise in density and the majority of people living in large urban centers making use of increasingly smaller living spaces, there has come a push towards modularity in interior architecture. For this reason, bunk beds and lofted sleeping areas have become a great solution to maximize square footage. 

The concept of prefabrication in construction corresponds to elements, parts or entire buildings produced in a factory and transported to a construction site for a quick installation. This represents numerous advantages over traditional construction methods, such as speed, precision in execution, efficiency, cleanliness of the work and, in many cases, cost. Considering that housing is a primary human need, using industrial methods for the construction of affordable and good quality housing has always interested architects, whether to house growing urban populations or for temporary or emergency settlements, on the most diverse scales. After many attempts throughout history, the question remains whether the popularization of prefabrication in the construction field can be a solution to provide greater equity in access to housing.

Researchers credit the Hanging Gardens of Babylon as the first examples of green roofs. Although there is no proof of its exact location and very little literature on the structure, the most accepted theory is that King Nebuchadnezzar II built a series of elevated, ascending terraces with varied species as a gift to his wife, who missed the forests and mountains of Persia, their local land. According to Wolf Schneider [1] the gardens were supported by brick vaults, and under them, there were shaded halls cooled by artificial irrigation of the gardens, with a much milder temperature than the outside, in the plains of Mesopotamia (present-day Iraq). Since then, examples of green roofs have appeared all over the world, from Rome to Scandinavia, in the most diverse climates and types.

The choice of Lacaton & Vassal to receive the 2021 Pritzker Prize was, above all, emblematic. Under the mantra “never demolish, never remove or replace, always add, transform and reuse”, the French duo built a career focused on renovating buildings, providing them with spatial quality, efficiency and new programs. Their approach contrasts with most of the architecture we are used to honoring: iconic, imposing and grandiose works. It also contrasts with the notion of the tabula rasa, of building and rebuilding from scratch, so well represented in Le Corbusier's Ville Radieuse, and which has fascinated architects and urban planners ever since.

Every time we publish an article about Hempcrete, we get a lot of comments on social media - with a certain level of irony - about what would happen if the material caught fire. This is actually a legitimate question, as there is still a lot of confusion about the differences between marijuana and hemp, both of which come from the same plant species (Cannabis Sativa). But while marijuana has psychoactive effects due to tetrahydrocannabinol (THC), mainly present in the flowers of the plant, hemp-based building materials are produced from its stem, which contains small amounts of THC. To quickly answer the title question: no, the building won't be destroyed in the event of a fire. In fact, some tests have shown that these materials have excellent behavior against fire, dissipate flames, maintain structural integrity, and don't emit toxic smoke.

“Local” is a word that is broadly used to describe something particular about a place that makes it different from somewhere else. Across the globe, the “local-ness” of our cities is what makes them unique- in the way that people live, work, socialize, and especially in the way that they plan and construct cities and infrastructure. To someone living in a suburb, the way that they move from place to place might be through a car, while someone who lives in a dense metropolis might use a subway or bus system as part of their everyday lives.

All human activities affect the environment. Some are less impactful, some much, much more. According to the United Nations Environment Program (UNEP), the construction sector is responsible for up to 30% of all greenhouse gas emissions. Activities such as mining, processing, transportation, industrial operations, and the combination of chemical products result in the release of gases such as CO2, CH4, N2O, O3, halocarbons, and water vapor. When these gases are released into the atmosphere, they absorb a portion of the sun's rays and redistribute them in the form of radiation in the atmosphere, warming our planet. With a rampant amount of gas released daily, this layer thickens, which causes solar radiation to enter and and stay in the planet. Today, this 'layer' has become so thick that mankind is beginning to experience severe consequence, such as desertification, ice melting, water scarcity, and the intensification of storms, hurricanes, and floods, which has modified ecosystems and reduced biodiversity.

The art of building a shelter made from blocks of ice is passed on from father to son among the Inuit, native peoples who inhabit the northernmost regions of the planet. The circular plan, the entrance tunnel, the air outlet and the ice blocks form a structure where the heat generated inside melts a superficial layer of snow and seals the gaps, improving the thermal insulation of ice. In a storm, an igloo can be the difference between life and death and perhaps this is the most iconic and radical example of what it means to build with local materials, few tools and lots of knowledge. In this case, ice is all you have.

Wood is an extremely versatile material. It allows for the construction of robust and strong structures, while it can also be used as the raw material for delicate objects such as musical instruments. Understanding all its particularities, properties, and behavior is a journey of knowledge that could take a lifetime. Basically, wood is made up of cellulose, hemicellulose, lignin, and mineral elements, and each species has its own unique characteristics. The history of Stradivarius violins, for example, is interesting to mention: they are still worth fortunes and experts argue that luthiers have never been able to replicate their timbre on newer instruments. Researchers point out that the differentiated sound is due to the wood in the body and arm, which went through a submersion process with a mineral solution that increased the decomposition of hemicellulose. The treatment made the wood absorb less moisture, making the sound brighter and more pleasant.

Not every architectural project can incorporate a landscaping project, consider a garden or access to ample green space. Smaller spaces need more creative strategies to incorporate vegetation. Regardless of the context, plants offer benefits in all types of spaces, such as indoor temperature regulation, an option for sustainable production on a smaller scale than a greenhouse, in addition to their aesthetic qualities. In this article, we present 4 simple strategies and a selection of examples for incorporating plants in small-scale spaces, all of which can be found in Architonic's Planting section.

Flooding is a significant problem for buildings all around the world, including architectural treasures like the Farnsworth House that have been plagued by the issue time and time again. In particular, one-third of the entire continental U.S. are at risk of flooding this spring, especially the Northern Plains, Upper Midwest, and Deep South. In April of 2019, deadly floods decimated parts of Mozambique, Malawi, Zimbabwe, and Iran as well, resulting in a low estimate of 1,000 deaths while tens of thousands more were displaced. While architecture cannot solve or even fully protect from the most deadly floods, it is possible – and necessary – to take several protective measures that could mitigate damage and consequently save lives.

The climate has changed, and we have been left grappling with the consequences: high temperatures, flooding, drought and much more. As the world shifts (or tries to shift) to ways to mitigate the crisis, the architecture and construction industry finds itself in a particularly important position whose choices can create real impact. Some of these choices can include innovative products that offer real solutions to complex problems, such as the cooling down of temperatures in highly dense cities.

The automation of architectural design and rendering has been further accelerated by digital production tools. Tools such as 3D printers, assembly robots, and laser cutters, have all but perfected the design and construction process and have proven essential in optimizing resources, improving precision, and increasing control of the process.
