ºÚÁÏÍ·Ìõ

This 1½-day workshop explores classical methods for resolving two celebrated stair problems: balancing a quarter-turn stair (producing elegantly proportioned dancing winders) and designing a curved, Fibonacci staircase. We begin by laying out stringers, and treads using classical geometry (compass, straightedge, ruler and scaled drawings). Once the geometry is established, we introduce elements of stereotomy — three-dimensional cutting and template-development techniques — to convert the drawing into precise, shop-ready templates for material layout and cutting.

Instructor:

Patrick M. Moore is an internationally acclaimed carpenter, construction manager, and educator whose career spans multimillion-dollar projects and the preservation of traditional craftsmanship. With a distinguished background that includes leading mega projects for a top construction firm and earning global renown for his expertise in stereotomy, Patrick has become a celebrated authority in historic joinery and the French heritage technique known as L’Art du Trait. Notably, he is the first English-speaking "Compagnon Passant Charpentier" in France, an honor steeped in the rich tradition of the Compagnonnage, and the first North American to earn the Master Craft Certificate for Joinery from The Worshipful Company of Joiners and Ceilers in the United Kingdom.

Beyond his groundbreaking professional achievements, Patrick is a passionate educator and prolific contributor to the academic discourse on heritage carpentry. He founded The Professional School of Practical Stereotomy in Ottawa, empowering a new generation of craftsmen to master age-old techniques with modern precision. His work can be found in museums around the globe, from France to Japan, and his widely published articles in esteemed journals, underscore a career dedicated not only to the practical aspects of construction but also to the preservation and evolution of classical art and architecture. Recognized as a person with an "extraordinary ability" by USCIS, he has received multiple honors including investiture into the Order of Ottawa, The Premier’s Award, and an honorary degree. Patrick’s lecture promises to offer an unparalleled insight into the convergence of tradition, innovation, and craftsmanship.
