A groundbreaking project in the United States aims to set a new benchmark in architecture. Bevel, a proposed 12-story, 55-meter (180 feet) tall timber office tower, is slated to become the tallest of its kind in North America. The project represents a collaboration between Mithun and Waugh Thistleton Architects (WTA), with Skanska as the leading development firm.

Design and Development

Planned for downtown Bellevue, Washington, Bevel’s design treats timber as the key element of its construction. Skanska, known for notable projects like MetLife Stadium and London’s ‘The Gherkin,’ believes the tower could prove the commercial viability of mass-timber construction.

Innovative Design Meets Regulatory Challenges

Bevel’s development faces significant challenges, particularly in navigating building codes that have yet to be tested in the U.S. for such projects. While some timber housing projects have been built under Type IVB construction provisions, Bevel aims to show that a commercial office building can also comply and thrive under these codes. WTA highlights that “Bevel’s exposed timber structure design would maximize the height and story limits allowed by these new codes.”

Expanding the Boundaries of Timber Construction

“Of the 22 tall timber buildings under construction or built, only three are commercial,” notes Jennifer Cover, president and CEO of WoodWorks.

Cover explains that Bevel’s design, featuring entirely exposed timber ceilings, expands the possibilities for future projects. Initially conceptualized as both a conventional concrete and a mass-timber building, Bevel’s cost comparison showed that focusing specifically on timber allowed for cost parity.

Sustainable Design Features

Targeting LEED v4 Platinum certification, Bevel emphasizes sustainability through various features. These include stormwater reuse systems, energy-efficient systems with full electrification, and biodiversity-oriented site design. The tower’s biophilic elements are designed to bring nature indoors through an inviting lobby with abundant natural light.

An Unprecedented Workplace Experience

If approved, Bevel aims to deliver a unique workplace experience focused on connection, wellness, and a sense of place. Exposed timber columns, beams, and ceilings will define the interior, supported by steel and concrete systems suitable for a high seismic zone.
