Party Wall Type A.PNG — What is a party wall?

A party wall is defined most simply as a wall that is shared by two adjacent properties, where the boundary of the two properties is located within the shared wall.
This occurs in semi-detached, terraced properties, flats, etc. Detached properties can have party structures eg: adjoining garages with a shared wall (important if wanting to extend your garage upwards to create additional storage/office space, etc) as well as brick and concrete boundary walls being considered "party fence walls".
It is important to note that as owners build extensions to their properties the relationship of structures to the boundary can vary along the length of the boundary. A property can have a mixture of party walls and non-party walls.
