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!”

Joseph Mayo is an architect in Seattle and author of the first book devoted solely to mass timber commercial buildings. At Mahlum, he advised on the first installation of Oregon-made structural cross-laminated timber (CLT) in the country at Western Oregon University’s Richard Woodcock Education Center. He recently completed a series of three CLT classroom buildings in Washington State.

An advocate for the use of mass timber, Joe 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 building. Recently, as Chair of Forterra building Code and Regulations Action Team, Joe helped to successfully pass new building codes in Washington State that will recognize mass timber as a construction type, and allow up to 18 stories of CLT building. He also helped form the AIA Seattle Mass Timber Committee, actively working to spread knowledge on mass timber design and construction.

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.

Joe holds a Master of Architecture from University of Oregon and a Bachelor of Arts in Communications from University of Washington.
