In Japan, the cob construction is often used for fences, but is rarely used for buildings. These buildings are being dismantled by aging and change of owner. We conducted measurement on the warehouse and the wall built with the cob construction method around the Yamanobe road in Nara prefecture. As a result, it is found that there is relationship between the structure of the warehouse, the area and the application. Furthermore, it was possible to estimate the construction method from the states of the mud wall.
