Editing Semi-detached (section)

==Outside the United Kingdom and Ireland==
Although semi-detached housing is built throughout the world, it is generally seen as particularly symbolic of the [[suburbanisation]] of the [[United Kingdom]] and [[Ireland]], or post-war homes in [[Canada]]. In [[Toronto]], the semi-detached house was a major building type during both the pre and post-war periods. In [[New England]], some other parts of the United States, and occasionally in Canada, this style is colloquially called a "[[Duplex (building)|duplex]]''"''. Elsewhere, however, "duplex" refers to a building comprising two flats/apartments, one above the other; this is also referred to as a "two-flat'.<ref>{{cite web|url=https://www.wbez.org/shows/wbez-news/the-tale-of-the-two-flat/8a385f49-42d6-4cd1-8978-666181064d59|title=The Tale of the Two-Flat|date=August 20, 2014|publisher=wbez.org}}</ref> Semi-detached houses are typically referred to as 'twins' or 'double-blocks' in the [[Mid-Atlantic states|Mid-Atlantic region]] (particularly in [[Pennsylvania]]).

In [[Australia]], a semi-detached house is also known as a "duplex". Townhouses may be apparently similar to semi-detached houses, but a semi-detached house sits on a single property, owned in its entirety by the owner of the semi-detached house, whereas townhouses sit on a shared property. The type of real property title held is therefore different: a semi-detached home is generally held as a [[Torrens title]]d property, while a [[townhouse]] is a [[Strata title]]d unit. Semi-detached houses come only in pairs, whereas there may be more than two townhouses attached together. In [[Sydney]], semi-detached houses were briefly popular at the beginning of the 20th century and many examples may be found in inner suburbs such as [[Drummoyne, New South Wales|Drummoyne]]. However, this style quickly gave way to the 'modern' style of detached housing which allowed better motor vehicle access, amongst other benefits.{{citation needed|date=December 2015}}

===Canada===
The semi-detached house was seen as a good fit for downtown [[Toronto]]'s narrow lots early in the city's history. In the late 19th century semis were built in areas such as [[The Annex]] and [[Cabbagetown (Toronto)|Cabbagetown]] in assorted styles: Gothic Revival, Queen Anne, Second Empire, [[bay-and-gable]].<ref>{{cite web|url=http://ontarioarchitecture.com/Styles.html|title=Styles Page|first=Shannon|last=Kyles|website=ontarioarchitecture.com}}</ref><ref>{{cite web |url=http://www.oaa.on.ca/news%20&%20events/news/detail/Snoop-behind-closed-doors/263 |title= StackPath|website=www.oaa.on.ca |archive-url=https://web.archive.org/web/20150427124819/http://www.oaa.on.ca/news%20%26%20events/news/detail/Snoop-behind-closed-doors/263 |archive-date=2015-04-27}}</ref>

Semi-detached homes continued to be built in the post-war period, often alongside detached types such as the [[bungalow]]. They remain popular with developers as they are cheaper to build than detached houses. According to the 2006 census, Toronto had more than 139,000 semis, more than any other Canadian city by a wide margin.<ref>{{cite news|url=https://nationalpost.com/posted-toronto/dont-get-too-attached-a-primer-on-the-semi|title=Don't get too attached: A primer on the semi|date=3 March 2012|newspaper=National Post|last1=Mirsky|first1=Jesse}}</ref> Red-brick semis are a common sight throughout downtown and older suburbs.{{citation needed|date=December 2015}}
