You've been offered advice yet you seem to have all the answers so it seems confusing why you bothered posting?
So I guess you wouldn't advocate living in flats or townhouses, or perhaps any building with more than 2 storeys?
You haven't offered advice, advice suggests it would be something of use.
To the OP, you will need to check with your individual council. From the description I cant see why you need to inform the council but councils can be so wildly different you never know.
I would ring their planning dept. and ask the question hypothetically.
