Party Walls – What Are They?George Gaduzo
Party walls are the shared walls or elements of structure between two or more properties.
Most commonly in a terraced or semi detached house situation it will be the central dividing wall that you share in common with your neighbour or neighbours if you live in a flat or maisonette.
In the latter case it is not limited to a wall, and could be a floor, or roof.
Many people think that they can knock an opening in a structural internal partition wall and that as long as they have a structural engineer involved all is ok.
I know of a recent case where the home owner ( referred to in the act as the Building Owner) had an opening knocked through to join the Kitchen with the Livingroom, had a structural engineer to assess and design a new beam, started the work and then had a call from a rather upset neighbour that ( AO adjoining owner ) quoting the Partywall Act and breaches of the law.
So if in doubt seek advise and whatever you do, don’t start work without your eyes wide open.
