Hi everyone, we bought a house almost 5 years ago now. The left hand wall (along with the rest of the house) needs re rendering but the neighbours built an extension around 8yrs ago now (before we moved in) that is around 15cm from our wall. This wasn’t picked up in the survey as a potential issue, nor was a party wall agreement highlighted as part of our purchase (and I don’t think one was put in place as they said they built within the existing building line, albeit what was already there was a tin shed). In retrospect we should have noted this, but is there anything we can do how? It’s not physically possible to do much to the wall as is. Help and thanks!
