The attraction of earthen plaster walls is the abundance of textures soil offers. Just as in ceramics, the soil color often changes with region. Naturally, their use helps prevent Sick House syndrome caused by allergies to wallpaper glue, and they also excel at humidity control.

But more than all that, working the surface of an earthen wall allows you to set the image or theme of a space. The level of straw in the mixture or the color of the soil can help determine if a space feels stiff and formal, or homely, or gentle and welcoming, and thinking about how to leverage that is an important factor in its use. There is also appeal in the variety of textures the plasterer can bring out through their trowel. Spaces are often classified into "Formal-Semiformal-Informal," and I feel that earthen stucco walls are important enough to qualify for that same classification. I would like to make spaces that better evoke the creativity of earthen walls. Our earthen walls were made along with Mitsuru Konuma's Suido Group.

There is some risk in using these walls in commercial environments, though, as a large number of people will be using the spaces with no way to predict how they will treat the walls, and any damage requires complete replastering. There are strong earth-like walls containing mortar, but unfortunately, they don't have the flexibility or humidity control characteristics that are so appealing in earthen plaster walls.
