Pueblo houses, also known as adobes, are traditional dwellings of the Pueblo people of the southwestern United States. They are made from sun-dried mud bricks and are usually rectangular in shape with flat roofs. Adobes are typically built in clusters and are often surrounded by a wall for protection. The walls of the adobes are thick and can be up to two feet thick in some cases. The roofs are usually made of wood and covered with a layer of mud or clay. Adobes are designed to be energy efficient and provide shelter from the harsh desert climate.
