Wood: The Latest Architecture and News

Created by a series of angled parallel lines that form a mesmerizing zigzag, the herringbone pattern has withstood the test of time and remains present in diverse design styles. Named after the resemblance to a fish's bones –a herring, for instance–, this classic V-shaped pattern arranges rectangular blocks in different proportions. With varying block edge length ratios, such as 2:1 or sometimes 3:1, the versatile design adapts to a wide range of uses, dimensions and materials. 

The arrangement of the blocks, even when used in single colors, creates a subtle texture and adds visual interest. While the herringbone arrangement may seem simple at first glance, the strong directional quality of the typically 45-degree angle lines requires a careful design process for a seamless and consistent look. The pattern can be found in walls and floors, from fabrics to wood and tiles. By playing with geometric shapes, it continues to be a trend that infuses style and structure into interior design while complementing a space's overall aesthetic. Below we dive into Architonic’s catalog to present different ways to apply it, exploring ceramic, wood, and synthetic herringbone patterns.

Timber is a natural, renewable material, easy to fabricate, and with low-carbon emissions. As a construction material, however, when put under enough directional force along its grain, sawn timber is structurally unstable, so deemed unsuitable under higher loads. In comparison, the manufacture of cross-laminated timber (CLT) involves simply gluing multiple layers of timber together at right angles. By crossing the direction of the grains, CLT achieves a far higher level of structural rigidity along both axes. CLT boards start with a minimum of three layers but can be strengthened further with the addition of more. Simply put, due to the complex physics involved in the perpendicular lamination, the strength of CLT board is similar to that of reinforced concrete, and has proven performance under seismic forces.

So what’s new? Wood’s been around for long enough now, and we’ve been using it as a building material for centuries. Surely this isn’t the first time someone’s realized it gets stronger the more you use it? Well… as you’d expect, the changing popularity of cross-laminated timber in construction does coincide with a greater understanding and focus on environmental causes, but the relationship hasn’t always been positive.

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.

Towers, walkways, decks, cabins and tree houses. Since 2010, the Hello Wood Festival has erected dozens of temporary constructions, with one common denominator: wood. The initiative aims to make knowledge about this material more accessible to everyone, as it has immense potential for the future. However, despite its potential, wood still faces various prejudices within the construction industry. Through the connection between designers and artists from different cultural, academic and professional backgrounds, the event uses construction as a platform for innovation, discussion and knowledge. It offers participants the unique opportunity to experiment with sustainable design and construction methods, encouraging learning through experience, held in a forested area near Budapest, Hungary.

From ancestral constructions to the "concrete of the future", terms abound to describe timber. Present in the history and horizon of world architecture, the material demonstrates a sustainable possibility and is associated with the coziness and warmth that it provides in the spatial atmosphere. In Brazil, it is no different. Several contemporary works explore the qualities and benefits of its use, including structural bias.

Prefabricated wooden houses date back to the 19th century, when so-called "kit houses" became popular in North America. Sold by companies like Sears, they offered affordable and convenient housing options, especially for people living in rural areas where labor was scarce and expensive. Customers could choose from a few designs and dimensions, and the kits usually included all the materials needed to build the house, including numbered and precut lumber, nails, shingles, and other necessary components. For some time, however, prefabricated houses were seen as constructions of lesser quality and prestige, and coupled with the lack of flexibility of these solutions, they went into decline.

Nowadays, thanks to the technologies available in the market, modular and prefabricated constructions have emerged as clean, sustainable, and energy-efficient construction solutions. In addition, innovations in engineered wood have emphasized its many uses, with the added benefit of aesthetic and structural possibilities. It was in this context that the office UNA BV developed the Modular 5.5 project, whose goal was to create flexible modular constructions that could be assembled in different arrangements, allowing the construction of houses with a variety of dimensions and needs in different terrains. We spoke with Fernanda Barbara and Fábio Valentim about this project:

From its outer skin to its structural framing system, a building is made out of many layers. Just like a human body, many of those layers – which tend to be the most crucial, functional components – remain unseen by the public, covered with aesthetic features. Among all the hidden elements, all buildings include sheathing, the outer casing that construction crews place to serve several key purposes: protect the floor, walls, roofs and ceilings, fortify the structure against internal and external forces, and cover the entire framework, giving the building a solid shape.

Wood is the most common material for sheathing, with Oriented strand board (OSB) panels usually being the top choice. Why? Made by compressing and gluing cross-oriented strands of wood together with heat-cured adhesives, OSB boards are lightweight, flexible, strong, versatile and fully recyclable. They also stand out by resisting deflection, warping and distortion, apart from offering some thermal and acoustic insulation. However, besides their good performance and mechanical properties, OSB is especially known for being cheaper than other alternatives, drastically saving both costs and time. In fact, this structural panel can be $3 to $5 less expensive than plywood, which explains why it is often considered its low-cost substitute.
