The existing wall is all natural stone. The new wall will be two 140mm wide breeze blocks with concrete cavity, with natural stone facing. The new wall is being built for strength. Ideally to put a fence on top.
The bank is solid clay. We have seen it. His fence was further away from our wall, but we can show he moved his fence up to our wall. We even have film of him drilling into our wall foundation and us trying to get him to stop. We have film of us discussing with his landlord, explaining the problems. He did this a few years ago. Again, I stress he has mental health issues.
The top of our existing wall is lower than the top of his fence. In the critical point it is about 48inches, 1220mm.
