A semi-detached house (often abbreviated to semi or semi-D) is a single family dwelling house built as one of a pair that share one common wall. Often, each house's layout is a mirror image of the other.
In the UK semi-detached houses are the most common property type, accounting for 32% of UK housing transactions and 32% of the English housing stock as of 2008. Between 1945 and 1964, 41% of all properties built were semis, but after 1980 this fell to 15%.
