Joseph Mayo


Associate Principal

“I’m an architect, author, and researcher of wood building. I’ve worked with CLT and have been involved in city and state coalitions to go beyond the building code with wood. Please see my book Solid Wood: Mass Timber Architecture, Technology and Design, and let’s talk timber!”

Joining Mahlum in 2008, Joseph Mayo is an architect and author of the first book devoted solely to mass timber commercial buildings. He has worked on over a dozen mass timber projects, including the Capitol Campus Childcare Center in Olympia, Washington (Mahlum’s first Net Zero CLT project); a multi-story, K-12 CLT prototype grant with the United States Forest Service; and he assisted in pushing for Alki Elementary School to be Seattle Public Schools’ first three-story mass timber school.

Joe has served on local and national AIA committees, co-authored a research paper exploring the economic viability of tall wood buildings, and assisted in teaching mass timber courses. He values the strength of collaboration and has worked with the City of Seattle Department of Planning and Development, and Washington State non-profit Forterra to lead investigations into the use of CLT in the building industry. As Chair of Forterra’s Building Code and Regulations Action Team, Joe helped to successfully pass new building codes in Washington State that now recognize mass timber as a construction type, allowing up to 18 stories of CLT building. Joe was also a founder of the AIA Seattle Mass Timber Committee and is currently a past co-chair.

Joe holds a Master of Architecture from University of Oregon and a Bachelor of Arts in Communications from University of Washington. He is a registered architect in Washington and a LEED Accredited Professional.
