Timber Frame Preservation

A Guide to Understanding, Documenting, and Repairing Historic Timber Framed Buildings

New Course

Beginning with a brief history of the craft of timber framing and an understanding of historic joinery and traditional layout systems, instructors Michael Cuba and Jack Sobon will teach students how to document and date historic structures using both traditional methods and high-tech gadgetry. The course will address the evolution of preservation philosophy, the United States Secretary of the Interior's Standards for the Treatment of Historic Properties, and applying for grants and tax credits.

The repair of timber framed buildings will be addressed for both in-situ and in-shop work, including shoring, dismantling, types of repairs, glues, epoxy, hardware, and appropriate structural considerations. Classroom presentations will be balanced with field trips to nearby old timber framed buildings for examination and documentation. Timber framed preservation projects underway or recently completed will also be visited.

This course is geared to contractors, architects, engineers, timber framers, and owners of old timber framed buildings. 


Jack A. Sobon is an architect, builder, and teacher specializing in timber framed buildings.  Since 1980 he has devoted his life to understanding the craft of timber framing.  Using only traditional hand tools and often starting right in the forest, he has framed and erected over 50 structures.  As an architect, he consults on historic structures as well as designing new timber framed structures.  He was a founding director of the Timber Framers Guild and founder of the Traditional Timber Frame Research and Advisory Group, an offshoot of the Guild.  He has four books to his credit including his latest: Hand Hewn, the Traditions, Tools, and Enduring Beauty of Timber Framing.

Originally from Bucks County, Pennsylvania, Michael moved to Vermont in the mid-90s where, as a student in college, he first began to hone his woodworking skills. Michael founded Knobb Hill Joinery with Seth Kelley to focus on preservation and restoration timber framing while occasionally designing and cutting new structures. He has spent a great deal of time documenting historic buildings, teaching classes, and demonstrating traditional timber framing methods. After moving back to the Mid-Atlantic in 2013, he founded Transom HPC and shifted his focus toward dendrochronology work and assessments of historic buildings.
