A party wall (occasionally parti-wall or parting wall, shared wall, also known as common wall or as a demising wall) is a wall shared by two adjoining properties. Typically, the builder lays the wall along a property line dividing two terraced houses, so that one half of the wall's thickness lies on each side. This type of wall is usually structural. Party walls can also be formed by two abutting walls built at different times. The term can be also used to describe a division between separate units within a multi-unit apartment complex. Very often the wall in this case is non-structural but designed to meet established criteria for sound and/or fire protection, i.e. a firewall.

👉 Party wall in the context of Hôtel particulier
Hôtel particulier (French: [otɛl paʁtikylje] ) is the French term for a grand urban mansion, comparable to a British townhouse. Whereas an ordinary maison (house) was built as part of a row, sharing party walls with the houses on either side and directly fronting on a street, an hôtel particulier was often free-standing and, by the 18th century, would always be located entre cour et jardin – between the cour d'honneur (an entrance court) and the garden behind. There are hôtels particuliers in many large cities in France.

Party wall in the context of Row house
A terrace or terraced house (UK), or townhouse (US) is a type of medium-density housing which first started in 16th century Europe with a row of joined houses sharing side walls. In the United States and Canada these are sometimes known as row houses or row homes.
Terrace housing can be found worldwide, though it is quite common in Europe and Latin America, and many examples can be found in the United Kingdom, Belgium, United States, Canada, and Australia. The Place des Vosges in Paris (1605–1612) is one of the early examples of the type.

The Place des Vosges in Paris (1605–1612) is one of the early examples of the type. Although in early larger forms it was and still is used for housing the wealthy, as cities and the demands for ever smaller close housing grew, it regularly became associated with the working class. Terraced housing has increasingly become associated with gentrification in certain inner-city areas, drawing the attention of city planning.
Party wall in the context of Semi-detached
A semi-detached house (often abbreviated to semi) is a single-family duplex dwelling that shares one common wall with its neighbour. The name distinguishes this style of construction from detached houses, with no shared walls, and terraced houses, with a shared wall on both sides. Often, semi-detached houses are built in pairs in which each house's layout is a mirror image of the other's.
Semi-detached houses are the most common property type in the United Kingdom (UK). They accounted for 32% of UK housing transactions and 32% of the English housing stock in 2008. Between 1945 and 1964, 41% of all properties built were semis. After 1980, the proportion of semis built fell to 15%.
Party wall in the context of Parapet
A parapet is a barrier that is an upward extension of a wall at the edge of a roof, terrace, balcony, walkway or other structure. The word derives from the Italian parapetto (parare 'to cover/defend' and petto 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires.
