Brutalism is an architectural style that originated in the 1950s and became popular in the 1960s. Its name comes from the French "béton brut," which means "raw concrete," as this material is one of the most characteristic elements of the style. Its main features are the apparent use of concrete, offering visuals where natural texture and tonality are the protagonists of the buildings. Brutalist buildings often have an austere and massive aesthetic, with simple and repetitive geometric shapes. The use of industrial materials and innovative construction techniques is also common in brutalism.
One of the most important elements in architecture are the vertical circulations that are translated into elevators or stairs, and although some offices decide to approach it in a discreet way, some others choose to pay specific attention to it and turn it into a sculptural piece. Helicoidal staircases are some of the favorites when it comes to focusing attention and in our collective conscience we keep some iconic examples, as is the case of the staircase in the O'Gorman House, this piece gave a certain character to the work and it is almost impossible to imagine it without it.
As the industry shifts towards a more sustainable model for construction, transparency becomes increasingly important. With a growing emphasis on building greener, architects, planners and other professionals want to make sure that the materials they are using have a minimal impact on the planet. Environmental Product Declarations (EPDs) are an important tool to accurately measure that impact.
In January, Holcim Germany became the first company in Europe to publish EPDs for its entire cement portfolio. It is also the first German company to provide its customers with product-specific ready-mix concrete EPDs.
From Taiwan to the Netherlands to Uruguay, Jakub Sawosko has extensively been photographing concrete architecture all over the world and displaying them on Instagram as @sh_sh_welt.
After living surrounded and fascinated by post-war concrete architecture in Europe in his early years, Sawosko moved to Taiwan where he eventually realized that Modernism had heavily influenced Taiwan as well. "I felt that [Taiwan's distinctive style of architecture] deserved more recognition", explains Jakub in conversation with ArchDaily via Instagram.

Roman aqueducts built more than 2,000 years ago are still in operation. The Pantheon in Rome remains the largest dome made of unreinforced concrete in the world, with a diameter of 43.3 meters. At the same time, it is not unusual to see structures less than a decade old collapsing. Understanding why Roman structures remain standing has been the subject of studies by many researchers around the world. Why, even in hostile environments such as coastlines or seismic zones, do these structures remain intact? Is there some miraculous material or method that has been lost in history? An international group of researchers led by the Massachusetts Institute of Technology (MIT) has shed light on these questions, discovering that these structures had a previously overlooked capacity for self-healing, and the potentially huge environmental impact it can have, to create more durable concrete structures in the future.
Widely recognized as being responsible for 8% of global CO2 emissions, concrete should be a blacklisted material, relegated to the shameful annals of architectural history. Rapid global urbanization, however, will ensure its unequaled production simplicity and structural strength help retain concrete’s firm grip on the construction industry.
If you can’t beat it, improve it: is the industry’s mantra on innovation, currently developing various alternatives to concrete or its constituent parts and admixtures. So with a concrete set for the environmental green list, the concrete revolution –using the material as an aesthetic exterior facade, interior decoration and fittings, or even in furniture and lighting, as well as a structural framework– is free to continue.
Material researchers and Ph.D. students at Imperial College London, Sam Draper and Barney Shanks have won the 2022 OBEL AWARD for Seratech, a solution for carbon-neutral concrete. With a special focus this year on “embodied emissions”, the OBEL AWARD jury selected scientists to obtain the architecture award to “encourage innovative cross-disciplinary solutions to the challenges of climate change”.
Upon becoming a sovereign country, free from British Rule, the people of India found themselves faced with questions they had never needed to answer before. Coming from different cultures and origins, the citizens began to wonder what post-independence India would stand for. The nation-builders now had the choice to carve out their own future, along with the responsibility to reclaim its identity - but what was India's identity? Was it the temples and huts of the indigenous folk, the lofty palaces of the Mughal era, or the debris of British rule? There began a search for a contemporary Indian sensibility that would carry the collective histories of citizens towards a future of hope.
When cities grow, fuelled by an expanding population, housing becomes an essential component of the urban character of a metropolis. Across the world, housing experiments have been propagated by governments and states, with mixed results, and undoubtedly mixed opinions. The Soviet-era housing estates of Central and Eastern Europe are particularly interesting in that regard. These mass housing projects have been dismissed as eyesores and viewed as unimaginative monolithic structures. The legacy of these developments, however, is a lot more complicated than that.

The Petroperú building, jointly designed by architects Walter Weberhofer and Daniel Arana Ríos, was the result of a state competition held by the military government of Velasco Alvarado in the early 1970s. The building, strategically located in the capital of Peru, within the prosperous district of San Isidro, was designed to house the recently created state company in charge of the whole petroleum process of the country (Petroperú S.A.). The monumental building, built and inaugurated in 1973, became the symbol of the newly installed regime.
Contemporary challenges and developments in technology inevitably trigger changes in the way we design and build our cities. SUMMARY, one of ArchDaily's Best New Practices of 2021, is a Portuguese architecture studio focused on the development of prefabricated and modular building systems. Striking a balance between pragmatism and experimentalism, the firm develops prefabricated solutions in order to respond to a driving challenge of contemporary architecture—to speed up and simplify the construction process. Founded in 2015 by the architect Samuel Gonçalves, a graduate of the School of Architecture of the University of Porto, the studio has presented at prominent events such as the 2016 Venice Biennale. We talked with Samuel about the firm's practical experience in prefabrication and modulation, as well as their experiments and forays into research.
Whether to mark a change of direction, to highlight its first steps or its own presence in a room, stairs that combine two or more materials tend to draw attention by establishing dialogs between particular characteristics of each material. Concrete, steel and wood are some of the most common choices to compose the structure of stairs due to their high strength and versatility. But, when combined, these different materials expand their individual possibilities and reveal how the design can be tailored to their peculiarities and connections.
The combination of textures, colors, and finishes among materials can provide a number of creative solutions for these elements used for vertical circulation, as shown in LÂM’s Home, by AD+studio and House 9A, by 23o5Studio, characterized by stairs with a sturdy and rough base that meets a light and sleek structure of steps. The opposite composition order, a lighter base that meets a robust set of steps, thrives ingeniously in Luis Carbonell's Casa Chulavista and messina | rivas' Angatuba House, where the light wooden stairs' base is followed by raw concrete steps.
For centuries and centuries we’ve built – and the diversity in our global built environment is a testament to that. The many different cultures around the globe have had different ways of building throughout history, adapting locally found materials to construct their structures. Today, in our globalized present, building materials are transported across the globe far from their origins, a situation that means two buildings on completely opposites sides of the world can be more or less identical.

Control of concrete strength and maturity in large-scale projects has traditionally been recorded and measured manually. Nowadays, there are new technologies that allow builders to melt sensors directly into the concrete, which –connected to a transmitter– show continuous data on the material's temperatures, sending this data wirelessly to the cloud platform. The software then automatically calculates maturity and strength based on historical data, so the concrete mix and strength development process can be followed from any device and in real-time.
These sensors, based on 0G technology from Sigfox –one of the main IoT (Internet of Things) operators worldwide– have facilitated the construction of one of the most innovative architectural projects in Europe, the Cactus Towers (Kaktustårnene) in Copenhagen, helping calculate the exact moment to remove the formwork that shapes its characteristic façade.
A masterpiece is often defined as the most remarkable work in an artist's career, one which highlights the height of their techniques and ideals. The Mona Lisa by Leonardo da Vinci; Michelangelo's Pietá; the Beatles' Sgt. Pepper's Lonely Hearts Club Band album. There are many examples, which are not always unanimously agreed upon. But what if what many consider to be the masterpiece was started by someone else, the credited creator didn't live to see its completion, and almost all of its documentation was destroyed? Catalan architect Antoni Gaudí and his world-famous Temple Expiatori de la Sagrada Família are examples of these complications. From a highly crafted stone construction to the most modern 3D printing techniques and high strength concrete, numerous technologies were and continue to be incorporated in the project's construction.
If only a few years ago 3D printing was viewed with a certain suspicion, recent news has shown that it is in fact a viable technology that is here to stay. On April 30, 2021, tenants of the first 3D printed concrete house in the Netherlands received their keys. The house in Eindhoven—the first of five within the 'Milestone Project'—fully complies with all the country's stringent construction requirements.

Metaphorically, building bridges equates to creating new opportunities, connections, and paths. The first bridges likely formed naturally with logs falling across rivers and natural depressions, though humans have also been building rudimentary structures to overcome obstacles since prehistory. Today, technological advances have made it possible to erect bridges that are both impressive and sculptural, playing a key role in transportation and connectivity. Usually needing to overcome large spans, with few points of support, bridges can be quite difficult to structure. But when is the bridge more than a connection between two points, instead resembling a building with a complex program? How can these 'bridge houses' be structured?
The world’s longest immersed road and rail tunnel design, the Fehmarnbelt link gets a go-ahead. The 18 km infrastructure, the longest of its kind, connecting Denmark’s Lolland Falster region with Germany’s Schleswig Holstein region across the Baltic Sea will shorten the journey between both countries to just 10 minutes by car and seven minutes by train.
