Wattle and daub houses (also known as asi, the Cherokee word for them) are Native American houses used by southeastern tribes. Wattle and daub houses are made by weaving rivercane, wood, and vines into a frame, then coating the frame with plaster. The roof was either thatched with grass or shingled with bark. Making wattle and daub houses requires a fairly warm climate to dry the plaster. These houses are permanent structures that take a lot of effort to build. Like longhouses, they were good homes for agricultural people who intended to stay in one place like the Cherokees.
