I'd like to do whatever I can to stop my new neighbour from building 'un hangar', or a big storage shed, next to our property. He's already taken six months to remove unwanted topsoil, and there's at least 12 months to go; the noise has been awful, our tourist season in 2008 will be difficult. And then if he builds his eyesore, we'll have to look at it every day. He's made no 'declaration de travaux' yet, nor applied for a 'permis de construire', partly because of a freeze by the commune while they redefine a few categories etc. Can I prevent him making noise, and can I stop his construction completely. I'm about to offer to buy the land off him for much more than he paid, this probably won't work I fear. Will hiring a lawyer help as a last resort? What are my rights? Could a petition work? Can we force him to grow trees round it? Anyone with experience of this out there? Many thanks
