Keeping the materials in their natural and raw form in the projects seems to be more and more popular in contemporary architecture. The modern style legacy of keeping the construction elements visible not only establishes a frank relationship between the user and the built environment but also allows for a more diverse material palette and can be a very important tool when designing interiors. Brick is perhaps the most popular material in this context. Nowadays, people use the term exposed brick "finishing", which gives the concept of exposed materials a whole new meaning, namely ornamental, sometimes even replicated as wallpaper or merely decorative tiles.
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.
The world of architecture and construction has observed, with increasing attention, technological innovations involving wood. Although it is a material that has been widely used for thousands of years, recent research involving industrial manufacturing and machining technologies has provided even greater quality control and an increased diversity of uses, causing it to be described by many as the material of the future. To this end, common myths including wood's lack of resistance to fire and the implausibility of using it to structure tall buildings have been debunked.
Kengo Kuma's architecture can be defined by its respect to Japanese constructive traditions and alignment with its context. Internationally recognized, the architect is known mainly for his wooden (or mixed) structures, which arise from a simple pattern of assembly and, which through different intersections and angles, generate a complex whole. The representations created by his team bring very specific details, ranging from didactic isometrics to complex parametric drawings. We have gathered details of five inspiring projects by Kengo Kuma that use wood.
The use of wood in the construction of Chilean houses demonstrates the possibilities offered by renewable resources available in the country. The benefits are multiple: wood can be an extremely sustainable material when produced and processed under certain conditions since it can have a very low carbon footprint. Meanwhile, as a construction system, it is characterized by its warmth, resistance, and durability.
Is wood the future of construction?
Rotation, displacement, and interleaving of blocks are some of the options that enable the diversity of raw brick patterns in architecture. The shape of these elements, usually used for the construction of walls, has been explored in a creative way to compose facades of residential buildings, representing the formal identity of the building itself and its relationship with its context.
In recent years, much attention has been given to timber constructions. Being a sustainable and renewable material, which captures a huge amount of carbon during its growth, the innovations related to this material have allowed for increasingly higher constructions. However, when we talk about wood we approach an immense variety of species, with different strengths, nuances, potentials, limitations and recommended uses. While there are extremely hard and heavy woods, with strengths comparable to concrete, there are other soft and soft woods that are suitable for other purposes.
Often recognized as one of the most widespread constructive materials in the world, brick is, with no doubts, very versatile, low-cost and easily applied. Although it usually used in vertical surfaces, it also presents excellent properties when applied to horizontal ones, like floors.
In addition to their aesthetic appeal, the use of raw materials can save resources by bypassing the use of additional coatings and processes. This type of solution was most commonly used in utility buildings, such as infrastructure, factories, and warehouses. Exposed concrete floors, for example, were primarily found in industrial spaces, parking lots, and gas stations. However, they are increasingly being used in structures of different programs due to their appearance, durability, resistance, and vast possibilities for finishes. But what are the main factors to be aware of when using a concrete floor for a project?
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).
The advent of steel in architecture at the beginning of the 20th century is considered as one of the most innovative construction developments in history, allowing architects to create structures with heights, flexibility, and freedom never seen before. Henry Bessemer invented the most successful steel-making process in 1855, but it was not until 1890 that the process was refined enough for construction. The first steel constructions on both sides of the Atlantic, the Rand McNally Building in Chicago and Forth Bridge in Edinburgh, were record-breaking structures of their time.
