We can help design a Party 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. Planning permission is not required to serve a party wall notice and, because you will have up to a year to start work once the notice has been served, it is a good idea to do this as soon as possible in order to avoid delays.
