Ancient Mesopotamian houses called ziggurats were made of mud bricks dried under the sun and were roughly 90 square meters. Egyptian houses were also constructed of mud bricks and called pers, sometimes resembling mansions with 25-30 rooms. Greek homes lacked a specific name but used sun-dried mud bricks and terra cotta or wooden roofs and were one to two stories tall. Modern Canadian houses include duplexes, apartments, and detached homes made of materials like wood, stone, metal and glass with civilians as residents, and duplex prices can reach millions depending on location.
