Roman Houses
Most people living in the Roman Empire lived with their whole family in one room of a sort of apartment house. These were built, like many cheap apartment houses in the United States today, around two or three sides of a courtyard, one or two stories high. The other sides of the courtyard had high walls to keep out burglars. Today we use these courtyards for parking, but Roman people (who didn't have cars) used them for cooking, and for children to play in. The apartment houses were generally mud-brick, with flat roofs that you could sleep on in good weather.
