Workshops and Courses

Information about workshops and courses

Workshops always start with a group dynamic and contain an exploration of natural building materials, a session on stove theory, and a discussion on the design of the project. After that the practical part starts. Towards the end of the course we like to do a design exercise with the students so they start to create ideas about how to apply the new skills and knowledge.

Please consider that a workshop focuses on the teaching and the students who participate. This means that projects might not get finished during the duration of a course, even though it is always the objective and part of the planning of a course and the design of the build project. The workshop leaders however, we are willing to finish a project after the course is over, but this has an additional cost. Thanks for your understanding!
