Semi-detached housing type often abbreviated to semi in the UK Tudor style house which is Mock-up, Canada and Australia, as in “three-bedroom semi”, consists of pairs of houses built side by side as units sharing a party wall and usually in such a way that each house’s layout is a mirror image of its twin. This style of housing, although built throughout the world, is commonly seen as particularly symbolic of the suburbanisation of the United Kingdom and Ireland, or post-war homes in Central Canada. Canadian Victorian examples can be seen in areas such as The Annex. This type of housing can be thought of as being a half-way state between terraced or row housing and single-family detached homes. Terraced housing is constituted by continuous row houses with open spaces at the front and back, while semi-detached houses have front, rear and any one side open spaces, and individual detached houses have open spaces on all sides. They could be seen as its answer to the New York City brownstone as a typical Semi-Detached too.
