The Tawakoni were a Caddoan people closely related to the Wichita and Waco, whose dwellings were conical in shape, made of a framework of poles covered with a thatch of grass, and were grouped about an open space which served for social and ceremonial gatherings. Couches covered with mats were ranged around the walls inside the house to serve as seats by day and beds by night. The fire was built in the center. All of these tribes were referred to as "Grass Lodge People" by other native tribes and in the Plains sign language.

Yuki Indian homes were cone-shaped. They began with a circle on the ground, with poles around the perimeter that supported themselves at the top. Over the poles, layers of bark, grass, pine needles and earth formed the walls. A low entrance tunnel was made of four forked sticks covered with poles and earth. Deer skins covered the door. Firepits were dug in the center of each house. Each village had a larger dance house, made the same way as the smaller houses, but supported by a center pole.
