Your path to becoming a certified straw bale builder: With STEP CERTIFIED, you can choose to participate in our Zoom workshops as well as the workshops in our training center and the Building Site Workshops and you have ongoing access to the online course.

The structure: The STEP training comprises 400 hours of training in 8 units. The STEP 6 and 8 units are pure theory modules, the theory of STEP 1, 2, 3, 4 and 7 includes practical days, STEP 5 Clay & Lime – Surfaces and Facades is a mix of theory and practice, so it only takes place „for real“. Here are the descriptions of the modules.
