It's safe to say that concrete is one of the most utilized construction materials in large-scale architectural projects. In Argentina, the use of concrete to construct high-rise apartment buildings offers a variety of advantages, especially when it comes to durability and the time it takes to build. This has made it the go-to material for many architects.
Thanks to its aesthetic qualities and malleability, concrete is the darling of the world's builders and architects. In Argentina in particular, concrete's durability and adaptability to a range of climatic conditions makes it one of the most sought after construction materials, demonstrated by, not only the country's countless museums, hotels, hospitals, but by its residential and smaller-scale buildings as well.
The Cultural Center was designed by architect Oscar Niemeyer and named after him. It is located in the city of Goiânia in the state of Goiás, Brazil, and was built on a 26 thousand square meter flat land called Esplanada da Cultura, a square dedicated to concerts and events, paying homage to former President Juscelino Kubitschek. The complex consists of four geometrically pure buildings: a rectangle that holds a public library, a cylinder where the Museum of Contemporary Art (MAC) is located, a dome that shelters the Music Palace, and a 36-meter-high pyramid that houses the Human Rights Monument.
While concrete is without a doubt the world's go-to building material thanks to its durability, malleability, and ability to withstand a wide range of climates, it is also the principal source of CO2 emissions within the realm of construction. To combat this and reduce their creations' carbon footprint, many architects have begun experimenting and innovating in a bid to optimize concrete's technical qualities while diminishing its impact on the environment. Among these efforts, there are several projects that have explored the possibility of replacing traditional frameworks with more sustainable materials like bamboo, a resource that grows in abundance throughout many regions of the world and, along with having minimal environmental impact, renders high quality textured detailing on a variety of architectural surfaces.
Oscar Niemeyer’s latest work generated a spherical extension for the Kirow plant’s canteen in Leipzig, Germany. The architect was first approached by the factory’s owner in 2011, and following Niemeyer’s death in 2012, his sketches were further developed by assistant Jair Valera, and executed by Harald Kern Architects.
Carbon textile-reinforced concrete is a composite of high-performance materials that is corrosion-resistant, thin, light, resource-friendly and environmentally friendly. It provides a basis for long-term endurance in construction, both in new buildings and in renovation or repair. Longevity and economic viability are two essential factors at which the construction industry, as well as research, politics and environmental associations, have demonstrated a keen interest.
In the dome of the Pantheon in Rome, several construction techniques were used to allow such a bold construction to stand. One concerns the composition of the concrete (in this case, non-reinforced concrete) with different densities throughout the structure. Closer to the top, lighter stones were used in the mixture, reducing the dome's weight retaining the solidity of the base. Another technique was the inclusion of “coffers”, which are nothing more than subtractions in the concrete, reducing the weight of the dome while maintaining a cross section sufficiently robust to support its own weight. Built almost 1,900 years ago, this building still surprises us with the genius of the solutions. Using a quantity of materials just high enough to fulfill its primary function, and creating intelligent structures as a result, is just one of the lessons that this building provides.
MAD Architects has just released its design for the Wormhole Library, a curved structure that serves as a multi-functional building, allowing visitors to read, enjoy the sea views and attend open-air performances. Located on the coast in Haikou, Hainan Province in China, the “wormhole” pavilion is now under construction and is expected to be completed in 2021.

Skating took root as a sport in California during the 1960s and 70s, a time when extreme activities like surfing found their niche among the United States populace. Beginning as an urban adaptation of surfing, skateboarding became the pastime of choice for adolescents and, by the 1980s, acquired a worldwide following. Soon, city-scapes across the globe began transforming as spaces were created for people to engage in this uniquely urban sport.
With its wide range of applications and cosmetic properties, concrete is having a moment in the world of architecture. Today, thanks to the ever-moving stream of innovation in concrete production and application, optimal results are now the norm rather than the exception. For architects and builders alike, concrete is an opportunity to explore and experiment with tones and textures, ensuring that there is something for every design and project.
Peter Zumthor, in one of his most emblematic works, gives concrete an almost sacred dimension. The work in question is the small Bruder Klaus Field Chapel, located in a small village in Germany, a construction that is both robust and sensitive. Built with white cement, which was mixed with stones and sand from the region, the chapel is composed of 24 layers of concrete that were poured day after day by local labor, and compressed in an unusual way. The building's flat and smooth exterior contrasts with its interior, which was initially made of inclined wooden logs forming a triangular void. To remove these internal forms, the logs were set on fire in a controlled process, reducing them to ash and creating a carbonized interior that varied between black and gray and retained the texture of the negatives of the logs. The result is a masterpiece of architecture, a space for reflection and transformation, in which the same material appears in diametrically opposing ways.
It's no secret that concrete has one of the highest CO2 emissions of all building materials, making it a focal point for architects looking to innovate and experiment with it as a way to optimize its production and application in construction while decreasing its environmental impact. This exploration of elements such as concrete's thermal inertia, which could serve to make buildings more energy efficient, as well as its durability, which guarantees a long-lasting, zero- maintenance structure even in the most extreme of climates. The ultimate goal is to create luminous living spaces with natural ventilation while simultaneously exploring the possibility of reusing frameworks as a way of cutting costs and streamlining the building process.
Having been utilized as early as the Roman era in buildings of almost every scale, it is almost impossible to think of a building that does not have at least one concrete element. In fact, it is the most widely used construction material in the world, due to its versatility, resistance, ease of handling, accessibility, aesthetics, and other factors. At the same time, its manufacture is also one of the main polluters in the atmosphere, mainly due to the fact that the cement industry emits around 8% of all global emissions of carbon dioxide (CO2).
In addition to its intensive production, concrete is an extremely rigid material, heavy and composed of cement, water, stone, and sand. Thus, would it be possible to continue to use concrete sustainably after demolition, eliminating its disposal as mere waste and overloading landfills?
The Tehran Eye is a contextual shopping center that caters to the needs and the common living practices in the Iranian capital. The project, conceived by Farshad Mehdizadeh Design, consisted of redesigning a façade and reorganizing a large existing structure into an integrated entity in the city.
August Komendant (1906–1992) was an Estonian-American structural engineer, whose collaboration with famous architects and engineers resulted in several 20th-century architectural masterpieces. His professional career spanned more than half a century from the 1930s to 1980s and coincided with an era characterised by modernisation, urbanisation and the rapid development of technology.
Gone are the days when the kitchen was relegated to a service area. Following the traditional system of bourgeois residential tripartition (dividing the house into social, intimate, and service areas), the kitchen was originally designed as an independent and closed space. Today, more and more, projects seek to integrate and relate it to other rooms in the house, facilitating different interactions among its residents. Due to this transformation, the appearance of the kitchen also changed, and traditional ceramic and stone cladding gave way to new materials.
