Row houses are a type of housing that is typically found in urban areas. They are typically two to three stories tall and are connected to other row houses in a line. The term 'row houses' can refer to two different types of housing: frats and brownstones. Frats are a type of row house that is typically owned by a fraternity or sorority and are usually found on college campuses. Brownstones are a type of row house that is typically found in older, more established neighborhoods. They are usually made of brick and have a distinct architectural style.
