Thanks All for your replies, I will contact my surveyor. The chimney stack is above my room and partially demolished. I think a lot of properties of similar design in the area no longer have them. Picture attached...

Apologies if I'm being silly, I'm a FTB and it has taken me 3 years of searching to find a flat in my budget that I love, and I'm now in the process of purchasing it. It's on the top floor of a converted Victorian property. One of its 'features' is a partially demolished chimney stack in the corner of the property (it's causing water penetration issues to the ceiling in one of the rooms, but that's a whole other story). The other day I was looking at pictures of other flats in the building and noticed that the downstairs neighbours seem to have a bit more space in the room directly below mine, in the corner where the chimney breast is supposed to be. It is their bathroom and somehow they managed to fit a sink on that wall. I attach the pictures (apologies for the awful quality). For reference, our windows are aligned, mine is directly above theirs. Is it likely that they removed the chimney breast leaving my flat unsupported, or am I panicking unnecessarily?
