About the Course

Explore using natural building materials and begin to develop the skills needed to build your own outhouse, garden retreat or even extend or build your own home. Whatever your grand design, this practical course can help put some of those ideas into focus, pick up new skills and learn the tricks of the trade from an experienced builder and Master Carpenter.

This course is a great introduction to learning a whole host of natural building techniques in a unique, supportive and inspiring environment. The course will cover:

• The practicals and theory of groundworks and foundations
• How to mark out, measure and cut timber accurately
• Building sections so you gain experience in timber framing, strawbale, hempcrete, rammed earth and earth plastering
• Making a section of roofing using pre-cut rafters
• Use felt and batons to help insulate the structure
• Learning how to install slate on a small area of the roof
