In this practical we will discover the simplicity and complexities of building with earth, look at how clay works as a binder, how local sub soil can be used in building and the benefits of earth re: health, breathability and thermal mass.

Be prepared to get a little messy and good shoes may be needed for stomping the clay.

You'll be able to get hands on and experience the variety of building techniques that are possible with earth, such as:

  • creating the formwork and building a simple 'rammed earth' wall, from subsoil
  • making an earth oven, using cob building techniques, including adding straw for structural strength and maybe some dung for elasticity and water proofing
  • making clay plaster to cover the oven and seeing how adding fibre can add to the insulation properties
  • using a brick maker to make compressed earth blocks.

    This session will be led by one of the lectures on CAT's MSc course, Louise Halestrap
