“New types of engineered timber that are considerably stronger and more stable than regular wood are allowing architects to build bigger and higher, with timber skyscrapers now a real prospect.”-www.dezeen.com
As we are about to enter a new year, we in the timber industry are asking,
Are we entering what architects are calling “The Timber Age”?
As more and more builders are seeking sustainable designs, some architects appear to moving away from conventional materials (i.e.steel, masonry, concrete) and embracing wood as the “architectural wonder material of the 21st century”.
And it’s no wonder. Builders and architects alike are recognizing timber for it unique aesthetics, sustainability, quality and speed of construction.
“This is the beginning of the timber age,” said UK architect Andrew Waugh in this recent article. Waugh’s firm is behind a housing development in London that will use more timber than any other project in the world.
In Portland OR, builders plan to build a 12-story tower the city’s famed Pearl District. In the Portland Tribune, Thomas Robinson of Lever Architecture says that this type of wood not only resists fires, it will have the ability to absorb the shock of a major earthquake.
These buildings are not limited to London and Portland. Plans for these tall timber buildings are also cropping up in Manhattan, Italy, Australia, British Columbia and many more locations all over the world.
The building material making these wooden tower structures possible is cross-laminated timber (CLT)– a large-scale, prefabricated, solid engineered wood panel.
Will cross laminated timber (CLT) take over steel and concrete as the preferred building material?
In it’s description of cross-laminated timber (CLT), APA – The Engineered Wood Association describes the material as “lightweight yet very strong, with superior acoustic, fire, seismic, and thermal performance, CLT is also fast and easy to install, generating almost no waste onsite. CLT offers design flexibility and low environmental impacts.”

Aside from the structural benefits of wood, there are other benefits to using this material in buildings. Exposure to natural materials has real and measurable health and wellbeing benefits for the building’s occupants. Corey Griffin, an Associate Professor at the Architecture School at Portland State University, says studies have shown that people are more productive and less stressed in buildings with access to natural materials.
In addition, research suggests that these modern wood structures may result in lower costs and a lower carbon footprint since production and processing of wood uses less energy than most other building materials.
This is a very exciting time for the timber industry as the technology, research and designs evolve. To learn more about this movement, we encourage you to take a look at some of these resources.
