Structural Insulated Panels (SIPs) are self-supporting panels consisting of a rigid foam core sandwiched between two structural coverings, typically OSB boards. These panels are lightweight and durable, produced in a controlled factory environment before transportation to the construction site. They can be quickly assembled to form floors, walls, and ceilings, creating a tight thermal and acoustic envelope. The panel's thickness is determined by the combined thickness of its components, and its weight should not exceed 20 kg per square meter.
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.
These blocks are available in a variety of dimensions and textures, ranging from traditional smooth surfaces to fluted or rough finishes. Additionally, there are special units designed for corners or beams with longitudinal reinforcements. The dimensions vary, from the classic 8x8x16 inches (approximately 19x19x39 cm) intended for structural use, to a size of 8x3.5x39 inches (approximately 19x9x39 cm) for partitioning walls. How can we creatively incorporate them into our designs?
As an additive manufacturing method, 3D printing has been characterized by the construction of objects through the horizontal deposition of material, layer by layer. This still restricts, nonetheless, the manufacture of elements and limits the shape of early prototypes to within the range that allows the addition of material in a single direction, making it difficult to create complex shapes with smooth curves.
However, the team from the Chair of Digital Construction Technologies at ETH Zurich—integrating computational design, digital manufacturing, and new materials—has been exploring an innovative non-planar robotic additive manufacturing system. This method facilitates the printing of thin structures with double curvature, significantly expanding the possibilities of their application in architecture on a larger scale.
Aiming to balance the calm and uniformity of minimalism with the tactile appeal of raw, textured materials, ceramics emerge as a versatile medium to bridge the gap between sterile spaces and those that might become overwhelming. Whether incorporating large formats or small mosaics, or embracing organic or geometric aesthetics, the diverse range of ceramic options enables the infusion of character into spaces while maintaining a sense of order and cohesion. But it is not a simple task. In the pursuit of this harmonious blend, we explore specific types of ceramic cladding that have been effectively applied in architectural projects, enriching the visual language of minimalism while grading its complexity with precision.
By recognizing and analyzing the multiple architectural possibilities of bamboo—a construction material mostly native to warm and tropical areas—the following questions arise: How can we take advantage of its qualities and enhance its use in colder climates? Such regions necessarily require a certain level of thermal isolation in walls, floors, and roofs—but for these climates, we can combine bamboo with materials that complement it.
We spoke with Penny Livingston-Stark, a designer and professor of permaculture who has worked for 25 years in the field of regenerative design based on non-toxic natural materials, to understand the opportunities offered by combining bamboo with earth.
A few years ago, the architects at Studio Bark, in collaboration with Structure Workshop and Cut and Construct, began to develop the idea of a circular kit of parts designed so that anyone with reasonable DIY skills could build their own structure. This is U-Build, a modular system made of wood panels crafted with the precision of a computer-controlled cutting machine (CNC). The panels are delivered to the construction site in a compact box, ready to be assembled, stacked, and screwed to shape the walls, floors, and ceilings. Only a few tools are needed, such as a rubber mallet, a drill, a tape measure, and a level.
While this system allows the construction of various types of buildings, its high level of customization finds particular utility and effectiveness in housing projects of all scales. From a tiny house for a couple opting for simplicity to an off-grid cabin in the woods, a Georgian cottage extension, and a 3-bedroom efficiency home, U-Build has brought extraordinary prefabricated wooden homes to life.
Brick beams have been widely used in construction due to their strength, durability, and aesthetic appeal. By embedding steel reinforcing bars into a series of bricks arranged in a specific pattern, these elements form horizontal load-bearing structures that distribute the weight and forces that act on a building. However, it is difficult to find brick beams with excessively large spans, in order to avoid long-term structural problems. Instead, they mostly come in the form of simple lintels, which can be easier to handle.
With a length of 16.2 meters and an impressive clear span of 15.8 meters, CEBRA architects have collaborated with the Randers Tegl group, the largest brick supplier in Scandinavia, to complete the construction of probably the longest brick beam to date. This exterior beam is accompanied by a 13-meter-span interior "sister" beam and is located above the main entrance to the Danish Crown's new headquarters in Randers, Denmark, extending freely between two of the building's wings. The longest beam is made up of almost 4,200 bricks – its height is made up of 25 rows of bricks, equivalent to 1.6 meters, and its edge consists of 4 bricks.
Kengo Kuma uses materials to connect with the local context and the users of his projects. The textures and elementary forms of constructive systems, materials, and products, are exhibited and used in favor of the architectural concept, giving value to the functions that will be carried out in each building.
From showcases made with ceramic tiles to the sifted light created by expanded metal panels, passing through an ethereal polyester coating, Kuma understands the material as an essential component that can make a difference in architecture from the design stages. Next, we present 21 projects where Kengo Kuma masterfully uses construction materials.

Due to its specific characteristics, the architecture of the sauna is interesting because it gives us lessons related to efficiency and the beauty of simplicity. These are generally very basic structures with a clear function, created to contain different levels of heat and humidity. Thanks to this steam bath, people can release toxins and improve their blood circulation. In addition, they are widely used in cold climates, in close proximity to nature and utilizing the presence of water.
To function, these normally airtight spaces contain a series of internal benches with different dimensions and a heat source that must reach temperatures between 80 and 90°C, including, if necessary, a chimney to expel the smoke. Wood is the material par excellence for saunas, using in most cases native species that maintain their rustic appearance and natural texture. Next, we review 9 saunas designed by architects, including some of their construction details.
The challenge of designing a house with a tight budget and space constraints, together with the essential duty of responding correctly to the requirements of the user, is sometimes one of the most challenging and motivating tasks an architect can face. How can you take advantage of space most effectively? How can you avoid wasted material? How do you anticipate the possible future expansion of the house? And how do you develop a simple design that also delivers value to its inhabitants?
To help you in this process, we scoured our projects archives to select 30 houses that provide interesting architectural solutions despite measuring less than 100 square meters.

The architecture profession is increasingly facing the pressures of a rapidly changing era marked by urbanization, population growth, and climate change. To effectively navigate the complexities surrounding architectural and urban projects, there has been an acceleration in the adoption and integration of data-driven technologies such as Artificial Intelligence (AI) and machine learning. However, valid concerns have risen regarding the potential loss of the designer's creative control, with fears that their role may be reduced to a mere "parameter adjuster." Is this a genuine possibility or merely a reflection of resistance to change?
In a conversation with Carl Christensen, Autodesk's Vice President of Product, we delve into the impact of AI on the traditional role of the architect and explore the opportunities that arise with these technological advances. As paradigms shift, forward-thinking architects and designers could find themselves especially empowered to expand their influence and shape a new future for the discipline.
Harnessing the power of moldless manufacturing through large-scale robotic 3D printing, research at ETH Zürich in collaboration with FenX AG delves into the use of cement-free mineral foam made from recycled waste. The objective is to build wall systems that are monolithic, lightweight, and immediately insulated, minimizing material use, labor requirements, and associated costs.
When it comes to seismic resistance, there are a number of myths that question the ability of wood to adequately perform in the event of an earthquake. However, its ductility allows it to deform plastically without breaking, absorbing and dissipating the energy generated by movement and vibration. Furthermore, unlike steel or concrete, wood is a lightweight material with a good strength-to-weight ratio, enabling it to withstand seismic forces without adding excessive load to the construction. This has been extensively verified in smaller-scale structures around the world, but how does a high-rise mass timber building behave in the face of an earthquake?
To dispel doubts, the Tallwood Project recently erected a 10-story building made of cross-laminated timber (CLT) at the University of California, San Diego (UCSD). The structure was tested on a shake table that simulated the 1994 Northridge earthquake in Los Angeles, magnitude 6.7, and the 1999 Chi-Chi earthquake in Taiwan, magnitude 7.7.
Climatic conditions are changing around the world, and with more extreme temperatures and limited resources, architectural and urban solutions must also change. How could our homes look and function effectively in a post-climate change scenario? Analyzing in detail the forecasts of these climatic variations, the architects of W-LAB have developed a Low-Tech habitat proposal for humid, hot, and arid climates, incorporating bio-materials, transportable solutions, and configurations that promote life in small and resilient communities.

During the 19th century, efforts to improve the quality of urban life focused on creating gardens and parks, marking the beginning of the evolution of landscaping as a modern discipline. However, despite remarkable examples worldwide, excessive structure and artificiality in urban parks have gone against the motivations that gave rise to them. In many cases, their design has resulted in decontextualized and inefficient public spaces that are highly demanding on resources and far from being truly sustainable.
The strict use of geometry and the imposition of species that are difficult to adapt and care for are gradually giving way to a more organic approach to landscaping, tailored to local ecosystems and more efficient in its development and conservation. Native forests embody all these positive aspects. They not only ecologically restore degraded areas but also improve air quality and retain rainwater, creating biodiverse green spaces that deeply connect people with nature. We spoke with Magdalena Valdés, founder and director of Bosko, who explains why native forests are the right path towards conscious and truly ecological landscaping.
David Chipperfield, laureate of the 2023 Pritzker Prize, has designed over a dozen museums throughout his career, with some still under construction. As a typology that has significant urban and social impact, Chipperfield and his team have skillfully leveraged each commission to transform neighborhoods and cities while still honoring the essence of the place and what was there before. His museums make powerful statements without being obtrusive, and this is reflected in the choice of materials and the construction solutions used.
Like an oversized minimalism, Chipperfield gives the materials space to unfold and be understood. In his galleries and museums, the materials appear exposed, clean, and highlighted through contrast. They give character to the space while giving prominence to the art on display, generating suitable atmospheres for its proper appreciation. Regularity, continuity, and repetition help shape this background, while the filtered light finishes building the right scene.
The bed, as an indispensable element, is an essential consideration in these experiments. Its functions can be fulfilled without completely losing the valuable space it occupies, and the bedroom experience can be enriched with careful thought. How can we reinvent and take advantage of the opportunities of the traditional bed?
During the first half of the 2nd century AD, one of the most important buildings in the history of Western architecture was erected in Rome: the Pantheon. Its main and most impressive feature is its coffered concrete dome, which ends in a perfectly round central opening. This oculus kicked off a series of later projects that noted the value of circular openings, which were replicated as glazed skylights and as compositional elements on facades. This eventually evolved, for example, into the detailed and colorful rose windows of the Gothic basilicas. In all its configurations, the oculus (meaning "eye" in Latin) holds symbolism that goes beyond that of a traditional window: its luminous projection gracefully marks the passage of time, solemnly highlighting an architectural space.
