Mastering Timber Framing Stereotomy: Crafting Timeless Structures with Practical Stereotomy

Immerse yourself in a practical learning experience focused on mastering the art of the ancient technique of stereotomy for timber framing. In this hands-on workshop, students will work collaboratively to construct an outdoor timbered structure on the school campus. Throughout the course, students will apply practical stereotomy techniques to solve for layout by snapping chalk lines on the floor of the building. They will then lay out the timber pieces on top of the drawing, extrapolate the layout onto the timbers, and cut the timbers independently.

Stereotomy, the age-old craft of accurately shaping and cutting timbers and stone for construction, has been inscribed onto the List of the Intangible Cultural Heritage of Humanity in 2010 by UNESCO. Under the guidance of Patrick Moore, participants will unveil the intricacies of timber layout and joinery through intuitive, stereotomical sketches drawn full size on the floor. This approach eliminates the need for complex calculations, allowing students to focus on the construction process. The course will delve into traditional joinery techniques as well as modern alternatives for efficient construction.

By the end of the course, participants will depart with newfound confidence and expertise, equipped to conquer 'complex' timber-framed structures with success. This workshop is ideal for those seeking to gain practical skills in stereotomy for timber framing, roof framing, and create lasting, functional structures with their own hands, all while honoring the ancient tradition of stereotomy that has been recognized by UNESCO.

This class is for advanced students who possess a working knowledge of how to cut timber frame joinery.  Students will work together with Patrick to layout the full-scale project on the shop floor.  The students will take layout information (length, angles and joinery placement) off of the full-scale drawing and layout it out on their timber.  Patrick will review layout and students will cut their timbers independently in class.

This 7-day class will take place inside the Heartwood School's heated, 35'x100' indoor shop in Alstead, New Hampshire.

This class is provided as part of the Heartwood School's efforts to provide instruction to adequately meet the needs of all students - from beginner to advanced.  This class will challenge students and provide opportunities for advanced learners to enhance their skill set on their pursuit to becoming a master builder.
