More Than Gray: 15 Projects That Explore Red Pigmented Concrete

Diogo Borges Ferreira — Thu, 31 Jul 2025 07:30:00 +0000

Concrete is often seen as the material of modernity, defined by its structural strength, raw finish, and unmistakable gray tone. It became the default palette of 20th-century architecture, a symbol of functionality and permanence. Yet, concrete is not bound to this chromatic identity. Its color is a byproduct of the cement, aggregates, and chemical composition used in its mix, and it can be intentionally altered through pigmentation. Among the many hues explored, red stands out — not only for its visual intensity, but for its ability to root buildings in place, evoke cultural references, and imbue architecture with a material presence that feels both elemental and expressive.

How to Save a Building from Demolition: Emerging Procedures to Uncover the Potential of Existing Structures

Maria-Cristina Florian — Wed, 07 May 2025 04:00:00 +0000

The twentieth century marked a definitive shift in the realm of architecture, as the Modernist movement broke from traditional building styles and encouraged experimentation and innovation. With the help of new materials and technologies, these times represent a crucial moment in the history of architecture as both cities and building styles evolved at an unprecedented rate. The structures that stand testament to this day are, however, nearing the age of a hundred years old. Their stark design features are not always embraced by the public, while the functionalist principles often hinder the adaptability of their interior spaces. Given that they also often occupy central positions within the city, there is increasing pressure to demolish these structures and redevelop the area in its entirety.

Raw, Refined, and Resilient: 14 Projects Showcasing Concrete Block as a Design Language

Moises Carrasco — Thu, 17 Apr 2025 04:00:00 +0000

Once seen as purely utilitarian, bare concrete blocks have increasingly become part of an architectural transformation. In regions where warm climates make insulation unnecessary, this material can be left exposed, free of cladding, finishes, or embellishment. In doing so, texture, bond, and form can define the building's character and simplify construction while creating new opportunities for expression and identity. This also creates a platform to explore the concept of material honesty. Beyond its aesthetic value, using a material "as is" can significantly reduce construction costs and minimize maintenance during the building's lifespan.

Moises Carrasco — Fri, 14 Mar 2025 04:00:00 +0000

Frank Lloyd Wright's architectural legacy is vast, but among his most enigmatic and atmospheric works are his Mayan Revival houses in Los Angeles, California. Residences such as the Hollyhock House redefine the interplay of light, materiality, constructive innovation, and spatial perception. By using modular concrete blocks in an ornamental and structural way, Wright developed a unique aesthetic deeply rooted in both the past and the future.

Sustainable Heating: Explore 4 Projects Featuring Trombe Walls that Enhance Thermal Efficiency

Clara Ott — Fri, 07 Jun 2024 07:30:00 +0000

A Trombe wall is a passive solar building feature that enhances thermal efficiency. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it. Solar radiation penetrates the glass during daylight hours and heats the masonry wall. This wall then slowly releases the stored heat into the building during the cooler nighttime hours, maintaining a more consistent indoor temperature without the need for active heating systems.

Agustina Iñiguez — Sat, 01 Jun 2024 07:30:00 +0000

Beyond being a prefabricated material currently produced in large quantities, the use of concrete blocks in architecture continues to evolve to meet the demands and needs of contemporary societies that are constantly changing. Whether in interior or exterior spaces, their use can align with concepts of circular economy, resource efficiency, sustainability, and more, with the goal of creating habitable spaces while also understanding their constructive advantages and disadvantages, their expressive and aesthetic qualities, and so on.

The Expressiveness of Exposed Concrete: Exploring the Works of Luciano Kruk

Agustina Iñiguez — Sat, 25 May 2024 07:30:00 +0000

In response to the diverse topographies and natural conditions throughout the Argentine territory, the works of Luciano Kruk propose an architecture that works in harmony with the environment, the landscape, and the nature in which they are situated. Whether immersed in a forest, on sloping terrain, or on a rural plain, among other geographies, his intention is to enhance the relationship between the interior and exterior of the architecture, using concrete as the main material in most of his projects.

Between Modular and Vernacular: How Combining Construction Techniques Can Bring Agility and Identity to Social Housing in the Global South

Camilla Ghisleni — Sun, 21 Apr 2024 07:30:00 +0000

The opening scenes of the award-winning Brazilian film "City of God" (2002) portray a newly constructed housing complex situated on the outskirts of Rio de Janeiro. Subsequently, this complex evolves into a hub of poverty and violence. Despite the film being set in the 1960s, the housing development depicted was a recent construction.

Concrete Blocks in Architecture: How to Build With This Modular and Low-Cost Material

José Tomás Franco — Tue, 09 Apr 2024 07:30:00 +0000

Concrete blocks are prefabricated materials primarily used for constructing walls. Similar to bricks, these blocks are stacked together and bonded with mortar, typically composed of cement, sand, and water. They are hollow inside to accommodate steel bars and mortar filling.

Concrete Pigmentation in Architecture: Beyond Neutral Bases

Helena Tourinho — Wed, 07 Feb 2024 05:00:00 +0000

Is it possible to assert the existence of a timeless material in architecture from an aesthetic standpoint? Undoubtedly, wood and concrete emerge as strong contenders, not only due to their representation of the solidity, volume, and mass of buildings but also because they provide a broad range of aesthetic possibilities in projects. Concrete, in particular, exhibits greater malleability in comparison to wood. While wood already offers flexible solutions, such as through CLT systems, concrete is derived from a blend of liquid, powder, and an aggregate—a paste that can be poured into a mold, spread over a surface and shaped into various forms.

Cement Can Be A (More) Sustainable Material

Eduardo Souza — Tue, 30 Jan 2024 07:30:00 +0000

"If the cement industry were a country, it would be the third-largest emitter of carbon dioxide in the world, with about 2.8 billion tons, surpassed only by China and the United States." This statement in Lucy Rodgers' BBC report on the ecological footprint of concrete stands out as quite shocking. With more than 4 billion tonnes produced each year, cement accounts for around 8 percent of global CO2 emissions and is a key element in the production of concrete, the most manufactured product in the world. To give you an idea, about half a ton of concrete is produced per person in the world every year, enough to build 11,000 Empire State buildings. With these huge numbers, is there any way to reduce this impact?

16 Materials Every Architect Needs to Know (And Where to Learn About Them)

Ariana Zilliacus — Sun, 07 Jan 2024 07:30:00 +0000

A building’s materiality is what our bodies make direct contact with; the cold metal handle, the warm wooden wall, and the hard glass window would all create an entirely different atmosphere if they were, say, a hard glass handle, a cold metal wall and a warm wooden window (which with KTH’s new translucent wood, is not as absurd as it might sound). Materiality is of just as much importance as form, function, and location—or rather, inseparable from all three.

Julio Vargas Neumann on the Future of Materials: 'Today's Reinforced Concrete will Disappear'

With an air of simplicity and wisdom, engineer Julio Vargas Neumann welcomes us. His two dogs accompany us as we descend after the necessary ascent to enter, and we are also accompanied by the stone walls defining the lot. We sit down and begin - or continue - the interview and conversation regarding the value of 'shicras', local materials, and earth construction. We also discuss criticisms of cement, aluminum, and steel, as well as perspectives on the future of materials in Peru and the world. Likewise, we delve into the long-neglected and recurrent rural problem in South America, discussing the inexorable need to change paradigms and priorities.

Innovations and Potential of CPC Panels in Decarbonizing Concrete Construction: Interview with Josef Kurath

Paul Yakubu — Fri, 20 Oct 2023 07:30:00 +0000

CPC concrete slabs are based on the technology of "carbon pre-stressed concrete," which originated from a long-term research project conducted by the Zurich University of Applied Sciences Winterthur (ZHAW) and Silidur AG, Andelfingen. These panels are reinforced with thin, pre-stressed carbon strands, allowing them to be three to four times thinner and lighter while maintaining the same load-bearing capacity as traditional reinforced slabs.

Architectural studio Parabase has been chosen for the development of several plots of Areal Walkeweg in Basel for the purpose of creating affordable apartments and an integrated migration center. The design solution, titled “Elementa,” reuses components from deconstructed cantonal properties, transforming the former columns and floor plates into walls and façade elements. The project was chosen following an open competition, where the international jury favored Parabase’s solution for its strong aesthetics combined with the creative reuse of prefabricated concrete elements.

Building Walls with Demolition Waste: The Poetry of Cyclopean Concrete

Eduardo Souza — Thu, 12 Oct 2023 04:00:00 +0000

Ancient cyclopean walls were built by overlapping raw stones, supported one on the other, without the use of mortar. The name derives from the Cyclops, the giants of Greek mythology, as their construction required seemingly superhuman effort due to the weight and difficulty of lifting and fitting each wall piece. Cyclopic concrete, in turn, mixes this ancient constructive technique with contemporary materials and techniques. What sets it apart from traditional concrete is essentially the size of the coarse aggregate, which is traditionally composed of stones but can also include brick or concrete remains. Our Projects section includes examples of this constructive technique, which, unlike the cyclopes, clearly carries traces of the workers who built it. We talked to Rafic Jorge Farah, from São Paulo Criação Office, about his experience with this technique in recent works.

“Achieving Sustainable Construction Is First Using the Right Material for the Right Job”: In Conversation With Seratech

Paul Yakubu — Fri, 06 Oct 2023 06:30:00 +0000

Seratech's technology, developed by Sam Draper and Barney Shanks, eliminates the CO₂ footprint of concrete and reduces carbon emissions in construction. This innovative process uses silica, a waste product from flue gases, as a carbon-negative cement replacement in concrete. By incorporating silica, the required amount of Portland cement is reduced by 40%, resulting in the production of carbon-negative concrete. This groundbreaking technology won the 2022 Obel Award for its focus on embodied emissions.
