The Hadza home changes with the season. In Spring and Summer they move every six to eight weeks, depending on hunting. They also relocate after a death or illness. During this period they live in huts. The huts are made from a framework of large branches woven together at the top. Smaller branches are then tightly interlaced to make up the second layer. This is then covered using a variety of materials, such as long grasses, liana, or tree trunks. There are also larger community spaces for cooking and dancing. In the rainy season the groups find homes in caves, located high up in the mountains.
