We have lived in our house for coming up 8 years now. 2 years ago new people moved in next door just before lockdown. We don't have much to do with them other than saying hi when they moved in and taking in parcels for them but they seem ok.
We live in terraced houses but each house has a single storey bit at the back that is detached. They're a kind of weird shape in how they are built because they are 70 years old, think a kind of wonky L shape. The wall of our extended bit sits very close to the boundary and as a result there is some overhang of soffits. This has always been the case and some of the neighbouring properties are the same.
Last week we had a planning letter come through our door. They plan to extend their little detached bit in both directions up to the boundary (single storey). I'm a bit shocked that they didn't speak to us before putting in planning permission, I know you don't have to but a heads up would have been good.
We popped round just to ask what their plans were, how long they thought the work might take as we both WFH so this would really impact us. It would also means gardens were not secure for a time period and we have children and a dog so this wouldn't be ideal, but is what it is. They talked us through their plans and I pointed out that the work they needed to do would mean altering our property as our exterior is currently in the way of where they want theirs to go. They just said "yes" without anything else. I tried to remain polite and asked why they hadn't spoken to us about this before putting in planning permission as this was not just proposed work to their property, but now ours. They shrugged and said ours shouldn't be built the way it is but they'd cover the cost for us. I pointed out that every property here is like it and if they wanted to extend they probably shouldn't have moved in to a house where there are boundary issues that have been known for 70 years.
We've had some back and forth with them offering nothing in the way of a you scratch my back, I'll scratch yours agreement, and just feel that we should let them do it. I've now said absolutely not.
I've spoken to the old neighbours who we are still in touch with and asked if they ever had any problems with the boundary. They said no but they did have to take out insurance that covered this in case our property ever damaged their garden etc. We have had to do the same because we have the same on the other side so this make sense.
I've gone through the deeds and any paperwork that I have regarding disputes, I even have really old building documents. No issues raised at any point in 70 years of this house being as it is.
AIBU or should neighbours move elsewhere if they're desperate to extend?
The house on the other side of them is empty so I have no idea what they're doing about that side.
