Our hands-on Building with cob course by Cob is a mix of clay, sand and straw. It can be used to hand-build load bearing walls, structures and pizza ovens. Cob is easy to sculpt by hand and is lots of fun to experiment with. Our course is very practical and covers mixing and building with cob to make a pizza oven. There are still spaces left on the 11-12 May Building with cob course. For more information and to book see the Building with cob course page: Building with cob course info
