Does building on party wall impact planning permission?

Hello,
We submitted a planning application to extend our ground floor flat.

In the designs, we built up to - but not on - the party wall boundary with one of our neighbours. So in the designs, we were building on our own land.

We have since decided we prefer to build astride the party wall, and have had a surveyor issue a party wall notice and will arrange for a party wall award with the neighbour. My question is, does this impact the planning application we've already submitted, which DID NOT show us building on the party wall. If we build on the party wall, the design will remain the same, it will just be that the wall starts on the party wall rather than just next to it.

Would we need to submit a new planning application or does it not matter for planning whether or not we end up building on the party wall, as long as a party wall award has been agreed with the neighbour?

Thank you

    I probably wouldn't bother.  You can submit an amendment, but it won't materially affect their decision, so it's called a non-material amendment.  

    If you want a belt and braces approach to planning, do it.  You might want the drawings for the neighbours anyway.

    Thanks - so if they approve the designs as is, it wouldn't be an issue if we did end up building astride the boundary (as long as we have a party wall agreement)? They couldn't enforce us to change the build, could they?

    It wouldn't be reasonable to do that.

    If by moving this wall closer to the boundary would result in any part of the proposal would overhanging the boundary, that would technically require you to sign Certificate B and therefore serve notice on the neighbour.
