I have found through the years that clients are often unaware of the full laws concerning Grade II listed buildings, Party Walls and the implications that may arise. Therefore I have added two links. The first link is for grade II listed buildings

and the second link is for Party Walls

I hope these will shed some clarity before you wish to embark on any projects.
