The Bevel tower, planned for downtown Bellevue, Washington, is set to be a pioneering example of mass timber architecture. Designed by Mithun and Waugh Thistleton Architects (WTA), this 12-story, 55-meter (180 feet) structure will redefine office design in North America.
Led by Skanska, a firm known for significant projects like MetLife Stadium and London’s Gherkin, Bevel faces approval stages. The project highlights timber as the core design element, demonstrating its commercial viability.
“Interpreting the building code for a type of project yet to be built in the U.S. was the biggest challenge,” said Skanska.
This endeavor explores Type IVB construction codes, which permit mass timber and non-combustible materials with fire-resistance ratings. Currently, no commercial office building has utilized these codes.
Bevel’s skeleton would be exposed, maximizing height and story limits based on these regulations. Following the unveiling of another tower—Australia’s tallest hybrid timber tower, Atlassian Central—Bevel aims to set its own records.
The building’s designs feature 100 percent exposed timber ceilings, expanding traditional possibilities and fostering advancement in timber usage for commercial spaces. The cost-effectiveness of mass timber lies in designing specifically around its properties rather than adapting it to older designs.
Structural integrity is supported by a steel core, fitting the seismic needs of its location, accompanied by underground concrete parking.
Bevel seeks LEED v4 Platinum certification. Its environmental focus includes stormwater management, energy-efficient systems, and biodiversity-oriented site design.
The tower incorporates biophilic design, featuring a nature-infused lobby with extensive glazing to enhance natural light, creating a warm and inviting environment.
Skanska emphasizes the unique workplace atmosphere and wellness-focused design.
