Ancient Mesopotamian houses were either built of mud brick or of reeds, depending on where they were located. People lived in reed houses near the rivers and in wetland areas. In drier areas, people built homes of sun-dried mud bricks. Mud brick homes had one or two rooms with flat roofs. The roof was an extra living area where families could cook and sleep on hot nights. Some houses had courtyards with a small garden or fruit trees. Homes, whether reed or brick, were simply furnished with tables, chairs, chests for clothing and kitchen ware. People slept on reed mats laid on the floor.
