Hi guys.
Was wondering if you'd be able to help me understand what's happening with my bathroom wall and bedroom walls. It's one wall that is the bedroom on one side and the bathroom on the other. It's a pretty old building that is now an annex attached to the main house. Due to it being bathroom related I assume that it's due to damp, but want to be sure before I do anything. I didn't paint the walls myself as the property is not mine, I simply rent.
Apologies for imgur links but the pictures I took were too large to be attached to this post.

Appreciate any insight you might have!
