Semi-detached house , sometimes just semi-detached, is a detached house built in two parts, which are often symmetrical.
Semi-detached houses are the most common type of private property in the UK , where they are built for one family. Their construction accounts for 32% of housing operations in the UK and 32% of the English Housing Fund (as of 2008 ). Between 1945 and 1964, 41% of all structures built in the UK were semi-detached houses, but after 1980 the percentage of semi-detached houses was only 15%.
Since 1815, the population of Great Britain began to grow rapidly, and private homes were expensive. For this reason, by the end of the 18th century, the first semi-detached houses appeared in the counties of Devonshire , Norfolk and Yorkshire , which were cheaper than ordinary cottages. Since the 1950s, such houses began to be built using prefabrication .
In Russia, semi-detached houses are most often designed for two owners.
