Terraced house

In architecture and city planning, a terrace(d) or row house or townhouse (though the latter term can also refer to patio houses) is a style of medium-density housing that originated in Europe in the late 17th century, where a row of identical or mirror-image houses share side walls. The first and last of these houses is called an end terrace, and is often larger than those houses in the middle. The terrace house has housed different parts of the social spectrum in western society. Originally associated with the working class, in modern times, historical and reproduction terraces have been widely associated with the process of gentrification.
