Timber Framers Guild

This covered bridge near Guelph, Ontario, Canada was a Guild project

The Timber Framers Compagnons du Tour de France in France, and Zimmerman in Germany (a German language site). The Guild is not directly associated with the United Brotherhood of Carpenters and Joiners of America. Originally the Guild was named the Timber Framers Guild of North America but the "North America" was dropped in recognition of the Guild's international presence.

Membership in the Guild does not necessarily reflect competency but an interest in learning and/or teaching. Membership is not required to practice timber framing. Most members build new timber frames, but many members restore, rehabilitate, preserve and/or study historic timber framed buildings. The philosophies vary widely with some members being innovative and designing buildings of the future, some use computer controlled machinery to cut frames, some work only with traditional hand-powered tools. Some members use metal connectors rather than traditional wooden joinery.

Sub-groups within or associated with the Guild

  • Traditional Timberframe Research and Advisory Group (TTRAG): Part of the Timber Framers Guild officially formed in 1990 to 1) To save and/or survey old or unique traditionally timber-framed buildings; 2) To develop a survey form and checklist prototype to be used by Guild members and others in cataloging old buildings, 3) To contact appropriate related groups to make them aware of our existence and services, 4) To develop methods and systems to examine the evolution of timber framing, e.g., transition of scribe rule to square rule in North America, 5) To develop a shared archive, 6) To create appropriate restoration policies and practices, 7) To promote the use of traditional materials and joinery in timber framing, 8) To pursue funding from all sources to achieve the aforementioned goals and practices.

The TTRAG group produced survey guidelines for recording historic timber framed buildings.

  • "The Timber Frame Engineering Council (TFEC) formed in 2005 at a Guild conference in recognition of the considerable number of structural engineers among the Guild membership and in response to a felt need for systematic research, discussion and codification of timber frame joinery and structural practices."[2]

The TFEC has developed a Standard for the Design of Timber Framed Structures as a "...supplement to provisions of the National Design Specification for Wood Construction..."[3] to assist engineers in this design specialty.

  • Timber Frame Business Council: A non-profit organization focused on the business of timber framing.


The Guild holds an eastern conference, western conference and TTRAG conference annually. Regional meetings, workshops and projects occur irregularly. For a list of past projects since 1988 see

Apprenticeship Program

The Guild has created a training program for apprentices to learn the art and science of traditional timber framing from mentors called journeyworkers. "Successful apprentices receive a nationally recognized credential registered by the United States Department of Labor under our program number NO152090893.[4] This program uses a formal curriculum which is still under development as of 2012.


The Guild publishes a newsletter for members, a respected journal Timber Framing, and books on the specialized topics of traditional timber framing. The Guild also lists other relevant books, software and a Glossary of timber framing terms. An important record of historic timber frame joints found in the U.S.A. is Historic American Timber Joinery: A Graphic Guide which was partially funded by a grant from National Park Service and the National Center for Preservation Technology and Training and thus are available for free download.[5] This guide is expanding as new types of joints are found and recorded.


An online, public forum is managed for anyone to search for past discussions or ask questions.[6]
