Western Wood Structures Western Wood Structures, Inc. The Top Mass Timber Erectors in the Northwest

Western Wood Structures has been in the living up to its name since 1969.

Working Wonders With Wood: Specializing in Design, Engineering, Supply, Installation, and upgrades of any heavy timber project, including Mass Timber, CLT, Sound Stages, Bridges, Shelters and Truss & Beam Projects. Decades before Mass Timber became a buzzword, Western Wood Structures has been designing, supplying and erecting some of the most iconic timber structures in the world. From the 530 ft. diameter Tacoma Dome in Tacoma, Washington to the 475 foot Cable Stayed Suspension Hiroshima Airport Bridge WWSI has been widely known for innovative designs and methods of erecting Heavy Timber and now Mass Timber structures. Founded in 1969 by a team of timber sales and engineering experts, WWSI has been a leader in the design and construction of timber structures including domes, bridges and other large timber structures. The original partners all traced their experience and training back to Timber Structures which was at the time the pre-eminent engineered timber supplier from 1940 through the 1960s. The WWSI team leveraged their experience and a can-do attitude to stay the industry leader for the next 50 years. Today WWSI’s sales team is supported by engineering, fabricating and jobsite installation teams. Whether you need an iconic structure like the Cathedral of Christ the Light in Oakland or a massive foot bridge to span a glacier fed river, WWSI can provide the design, means and methods to accomplish your goals.

Western Wood Structures is wrapping up fabrication and assembly of the timber package for the new Moorpark City Library in California. Designed to honor the region’s agricultural heritage, the 17,500-square-foot, single-story library features a modern barn-inspired aesthetic highlighted by exposed glulam beams and warm wood finishes.

The project includes glulam-steel hybrid trusses spanning up to 80 feet, creating large open spaces while showcasing the beauty and efficiency of mass timber construction. All timber components were CNC-fabricated by Western Wood Structures and shipped to the site fully fabricated, helping streamline installation and ensure precision in the field.
We're excited to see this new community space come together and look forward to the installation of these impressive long-span timber structures.

These standardized trusses allow for quick design and processing through the fabrication phase. Like most of our Alaska projects, this had a short building window. The five 45’ long prefabricated trusses will be installed in a great room. They can be flown into place immediately upon jobsite arrival because they were shipped assembled. Obtaining that high-end look while keeping the design simple and costs down is truly a win-win for everyone.

Cascadia Structural Timber Solutions provided the design, shop drawings, glulam, steel, and hardware.

At Bush Middle School in Seattle, CLT panels and glulam framing serve as both structure and finish, making exposed mass timber part of the spaces students and faculty will use every day.

The new central campus building brings together classrooms, labs, dining, and shared spaces. With WWS as the mass timber supplier and installer, it’s a project that puts timber’s structural purpose and architectural character on display.

This Joint Base Lewis-McChord (JBLM) project is a first of its kind in many ways. It's the first mass timber structure for the War Department, Western Wood Structures’ first joint venture with a general contractor, and our first project utilizing prefabricated walls manufactured in our North Fabrication Shop. Western Wood Structures has been on site since June 4th and has been working on this project since December.

This project is a testament to WWS’s ability to adapt, collaborate, and work as a team to accomplish great things. We were given six months on-site to install this 105,000-square-foot, five-story, 205-bedroom barracks.

A big shout-out to the people working hard on-site and representing WWS every day: Kevin, Troy, Danny, Mikey, and Antonio.

Before a 68-foot truss reaches the jobsite, it has to come together on the shop floor.

It takes plenty of skilled hands to turn individual members and connections into a structural assembly. We're proud of Western Wood's Swan Island team for a job well done.

A timber structure can do more than carry the roof. It can define the entire room.

At the Allenmore Golf Course Clubhouse in Tacoma, Washington, exposed heavy timber framing creates the interior's architectural rhythm. Repeated timber trusses, substantial columns and beams, diagonal bracing, and expressed steel connections remain visible as part of the finished space.

This is a great example of what exposed timber can accomplish when the structural system is also central to the overall architectural design of a space.
