Workshop “Practical Stereotomy: A Hip Roof from Layout to Assembly”

This workshop provides a holistic approach to solving seemingly complex timber framed roof designs. Participants will explore the art of solving an irregular (bastard) hip with equal overhangs using practical stereotomy.


õStereotomy has been in use since before ancient Roman times and has been inscribed onto the List of the Intangible Cultural Heritage of Humanity by UNESCO in both the French and Japanese carpentry context. UNESCO has also inscribed the workshops themselves, in the German cathedral construction context, where this knowledge is transmitted. The use of stereotomy is what made possible the construction of the great temples, churches, cathedrals, and fortresses around the world, many of which have become UNESCO world heritage sites.

Unlike modern conventional methods relying on algebra and abstract formulas, stereotomy transforms the layout procedure into a concrete visual process, eliminating the need for complex calculations. No calculators or computers needed! Using this drawing technique, students will learn how to solve intricate problems like the backing angles while having equal rafter overhangs. Students will solve the angles and lengths of the jack rafters and its connections between the hip and top plates.

This course is designed for architects, builders, carpenters, and professionals in the construction industry seeking a holistic understanding of timber roof intricacies. By the end of the workshop, participants will have not only enriched their theoretical knowledge but also gained valuable practical skills, making them adept at navigating the challenges presented by complex roof designs.

The supervisor of the workshop is Pat Moore, the founder and owner of The Professional School of Practical Stereotomy, a small private professional school. He has been teaching stereotomy to carpenters, woodworkers, furniture makers, and timber framers worldwide since early 2014, following his induction as a fully fledged member of the ancient guild system – Les Compagnons Du Devoirs. This UNESCO-listed organization traces its roots back to the 13th century in France.

The workshop is part of the main program of the International Log Building Conference: Revitalizing Heritage, which attracts log house builders and enthusiasts from around the world to South Estonia. We strongly recommend extending your stay to participate in pre-conference tours, engage with professionals at the conference, and witness the log house builders’ competition.
