Cracks starting to show.

Doozergirl, I've just looked at blown plaster images. It does look very similar.
It's just gone 12, I'm pretty sure my neighbours bedroom is the other side of that wall, so I shan't start knocking about just yet lol.
But will climb back in there, have a poke about and update tomorrow!

I climbed in there again today, sometimes being petite has its benefits.

I knocked the wall, doesn't appear to be hollow, I decided to pick a bit of the crack and low and behold, a chunk of plaster came off and I can now see nextdoor's brickwork!

There is no breeze block, when I looked into the crack yesterday there was some grey sediment and l assumed breeze block. It's just normal brick behind it.

I can't see any cracks externally on our property or theirs.

I think I would just take off the loose material and fill. And see what happened, but I don't think it would worry me too much unless it was splitting bricks?

Thanks everyone for the replies. We are continuing with works as planned, will ask for some advice from builder when they come to do the works. :-)
