What is on the inside of a wattle and daub house?

There are two stages to wattle

and daub construction. The first is the creation of wattles, interwoven branches, lathes, or rods that form a tight lattice. The wattle

can be used to lay the groundwork for walls both inside

and outside a home, or to fill in gaps between walls and ceiling timbers. Once the wattle

is made, it can be covered in daub, a plaster-like mixture of clays, mud, plant fibers, and animal dung. After the daub sets, many people whitewash the resulting wall to make it more weather resistant and to brighten it.
