@ OP; you mention going out 8m - so presumably you are using the prior notification procedure?
If that's the case, send your application in with details of overall size and position, and addresses of neighbouring properties etc, and see
what the LPA comes up with. If they do not believe it to be p.d., they will reject the notice and will probably write and tell you why.
This type of application is free, so you may well get their written opinion without having to pay for pre-app advice , or a LDC.
On the other hand, if they blindly accept it without considering whether or not it's p.d., and no-one objects, you're good to go.
[As for you, FMT, I shall deal with you later].
