Earth is a resource that exists everywhere on the earth, and there is little concern about its depletion. The resource recycling and moisture absorption/desorption properties of earth, which is only dried and solidified, are advantages that can be utilized in future construction. In Japan, the mud-bamboo wall construction method, which consists of layers of earth, has been mainly used, but it has many limitations in terms of construction period and cost. In other countries, a wide range of using earthen materials, such as rammed earth and sun-dried bricks, but many of them are assembled and are not suitable for Japan, which is an earthquake-prone region. On the other hand, the use of block-shaped earth units has the potential to free us from difficult techniques and constraints in terms of construction period and cost.

In this study, we develop a construction method that can be easily installed in building and ensures structural safety. The effect of the details of the proposed method on the structural safety will be investigated.
