Log building and Timber framing unite
one common center reference, one learning curve.
The first ever companion construction textbooks, based on the Four Forms of Big Wood Center Rule: Two for log building and two for timber framing.
These books are technically detailed and beautifully laid out, providing all the information required for both novice and experienced wood workers to build their own big wood projects.
A New Chapter
for ISBA and James

James retired from teaching in 2024 to complete his final books on Big Wood Center Rule and sail his boat, Joss. ISBA continues as the publisher of James’ books. It’s a perfect time for change. This transition allows James to pursue other areas of interest: working with First Nations on housing solutions and participating in log and timber educational opportunities around the globe.
