House
A row or terraced house (see the picture in the introduction) is a house that is part of a row of houses joined at the side walls. Many cities and towns have thousands of row houses because they are a good way to build lots of houses close together. Many row houses have two rooms downstairs and two rooms upstairs, with a kitchen or wash area at the back. Houses like this were built for poor factory workers and coal miners in many cities and towns.  "Terrace houses" are a type of row house where each house has a similar front to its neighbours.
