Scope note:

Residences that are separated by a shared wall, often a timber wall. May have been the result of dividing a larger residences into two. Distinguished from double houses (semi-detached houses), which comprise two separate but immediately adjacent residences, often on two properties, separated by party walls of masonry construction. A more easliy obvious distinguishing feature could be the front door; half-houses may have a single front door with a shared entry hall, while a double house will typically have two separate front doors.
