I have an end terrace(rendered) and my neighbour has a lean-to that slops towards my house. It is attatched front and rear to my wall, along the length within the structure is an airgap wall that gives about 4inch gap from my wall(gable end) to the internal wall of the structure. The guttering is in shocking repair(knackered) so water runs off the wall and down this airgap.
Obviously I cannot in no way shape of form get to the wall to make any repair or maintanence(even if I had permission to enter her lean to) bcause of the airgap wall.
A year ago I approached her to go halfs on knocking this down as it was in a poor state of repair and making good both of our walls for render and blocking the front with a gate for security. This was refused so we got the council enviromental health involved(unsure which dept to go to) they had building control come out to asses the fire risk.
6months later I'm no where my neighbour got her brother to pay for the front and rear to be recovered(by a builder) so it looks more attractive, the guttering hasnt been touched and now winter is onsetting I'm getting damp through the new decorating on that wall.I now have got the dept boss involved of the enviromental dept and I've been told all they can do is issue a guttering repair nothing more and I'll have to go to a solicitor.
I have a DPC with a guarentee with 10years remaining, the previous owner said he'd had no end of problems with her but the house was a steal for the price.
Apart from solicitors what direction can I take officially? What does the party wall act say ref this?
