Neighbour's planning application for new build requires underpinning of my wall!

From the point of view of soundproofing, would the op be better off with two separate walls, with a small gap between them? With flashing to make it all waterproof? 

OP would need to consent to the flashing being attached to their wall.

we inherited two large sheds in our garden that were about 6 inches apart. There was flashing on the roof but the amount of leaves etc that blew in the gap between them was a lot. Add driving rain to the mix and the ground level rose so much that we had damp in both sheds as a result. I know that a wall would be more sturdy than a shed, but a rising wet ground level could cause damp issues.

the OP would be stupid to refuse the flashing as it would protect her wall from water ingress.

The fact there is (or at least was) flashing covering the existing gap may also be relevant.

Cavity walls. As I said, not much gets between the two walls, otherwise planning consent would've been an issue.

Still sounds like a bad idea. If the wall ever gets damaged somehow, or if you wanted to install insulation, or a vent or something, it's going to be a pain.

Not sure if this might work and other more expert contributors will hopefully chip in…Can’t the OP just put in an application to build in a small window into their side wall? Building a window would presumably stymie the proposed adjacent development wouldn’t it? What about a couple of strategically placed extract fans on the wall? I don’t know. Just a thought.

how about a heat pump

Where are they putting that?  On the neighbours land? 

Trespass is not a solution.

Would the window idea work though?

maybe stuck on the wall like many Aircon systems around us - they tend to be overhanging land that does not belong to them - anyway I think the window is an interesting idea

At this stage of the game, unlikely. Same for putting vents in the wall.

yeah, with hindsight this is the best solution when you have a situation like the OP but often the window may not be granted planning permission as it overlooks the neighbour's land but yeah, it would be a good idea to do this if anyone has a side wall.
