It's come up in the searches that the house next door to the one were buying has had planning permission granted for a large extension. I've looked at the plans and it doesn't look like it will impact on us, it's the other side so not our boundary and no new windows on our side. I know there will be noise and mess but is there anything else I need to think about? I think it's a bit underhand of the vendors not to have mentioned it and I'm worried I've over looked something.
