What do they call the houses made from cow dung and hay?

There are several types of houses where the walls are mad of dung, clay and hay. Adobe houses would be one of them.

Medieval low cost homes were made in a Wattle and daub formation which is a composite building material used for making the walls, in which a woven lattice of narrow wooden strips called "wattle" was daubed with a sticky material usually made of a combination of wet soil, clay, animal dung and straw.
