Next door have just built their own garage and it's an inch away from our fence. The roof overhangs our garden and I'm not really happy about it. We didn't realise how close they were building to our fence until they got it to a level we could see and now they obviously aren't going to knock it down and start again. My partner has spoken to them once and they've said they roof won't come that far out they'll cut the wooden bits back - but there's no way they'll cut it back enough to not overhang at all? Their guttering will essentially be in our garden? I'm worried about devaluing our property to be honest, rather than just being picky. What can we do?
