Cob Buildings Germany 
When using cob building material it is called the cob construction. This is often used for renovating existing buildings, whilst rarely used for new buildings. Cob is unique, as every row has to dry before the next layer is added.
The key difference between Rammed Earth and Cob is that Cob has straw. This is why Cob has a lighter building density. Furthermore, cob is formed by using the hand until the desired height is reached. Each layer of cob can be up to 80cm in height before drying is required. A fork can be used to make this layer. In order to obtain smooth surfaces, boards are placed on each layer and any excess clays is tapped until smooth.
