Bit of a long-shot here, but I've just been talking to a friend who's going through hell with a developer working on the house next door - I was so horrified that I thought I'd ask whether anyone knows of any sources of advice or has any tips.
Basically, the guy keeps doing things that he's not supposed to, then appealing when the neighbours go to the council. They're now feeling that everything's stacked against them, and that the offending party seems to be getting away with everything he does.
Any battle-scarred veterans out there who can advise?
