Can neighbour object to permitted development extension?

[SenoraSurf]

We own a semi detached house and want to build an extension on the back, under permitted development. We have submitted building regs already.

Our neighbour in adjoining semi has written a snotty letter asking what we're doing (and strongly advising us to inform her), after she has noticed my husband doing some digging in our garden to check out ground type. She insists this 'excavation' could undermine her property's foundations- even though the area my husband dug is only 50cm deep and 3m away from the rear of our houses. Once we get the go ahead from building control, we would do the digging for the footings.

We have had issues with this neighbour before. History: The boundary between our homes belongs to us yet when we tried to repair the boundary, after speaking to her and explained our plans when we moved in, she went absolutely mad and said the boundary was hers... it's wonky as hell and zig zags massively over her land and ours but to save hassle, we just covered it over on our side.

Can this neighbour object/do anything about our proposed rear extension? We plan to build up to but not on the boundary (the fence will stay there). That obviously means the footings will be dug parallel to the boundary.

Advice and experiences welcomed.

What's the hold up?

God, she sounds like an insufferable woman. Well I hope it all gets sorted soon and when it does, I hope you drive her mad with noise when it’s it being built!😁

Also, even if the boundary is marked as yours to maintain on the deeds it may well be that she paid for the current fence at some point for some reason, in which case it would make sense that she was saying it's her fence.

This may be not be relevant at all but if your son is disabled he may be entitled to a Disabled Facilities Grant to make adaptations to the property to meet his needs.

The local council would then take charge of the whole process which would make it much easier for you! Obviously though that will delay things further.

Our party wall agreement cost us several thousand pounds and even when signed our neighbour would not allow us access on her property, so they had to build overhand.

It will be worth it in the end our neighbour has given us a year and a half of objections, made the application go to a planning committee and knocked on my door everyday of the build to complain. We still did it and everytime I go in and look at it I am glad I wasnt bullied into submission.

I just don't understand why some neighbours go out of their way to be absolute insufferable arseholes. I go out of my way to be nice to mine, I can't imagine ever causing such chew over them wanting an extension.

It’s down to the two surveyors to meet and agree a way forward. Has your met with hers? If not, why not? If they have then what’s the problem? You need to chase up your surveyor.
