We make our cob blocks from a North Devon vernacular mixture of sub soils, mixes, aggregates and straw and are ideally suited to the wetter climes of the Westcountry. They can be used for building and restoration work on traditional cob and earth buildings. Cob provides a great insulation for buildings and is eco friendly with a zero carbon footprint. Cob has been used in building the world over for many centuries and provided a cob property has a good hat (roof) and a good set of boots (stone plinth) should last for many years.
