They built several kinds of shelters. Some were open all across the front. They were made by setting several poles in a line in the ground and topping them with a ridge pole. More poles were slanted down from the ridge pole to form back and side walls, which were covered with brush. Other houses were dome-shaped with an entrance opening. Their houses were also made on a framework of poles covered with brush. Sometimes earth was packed against the brush on the outside walls. The home of the village leader was usually the largest house in the village. Shade roofs were sometimes attached to the house, to provide working areas outside that were protected from the sun.
