Not your usual fireplace thread
We have what we assumed to be a fairly standard fireplace
However in the process of doing other work we've discovered the chimney breast isn't really the chimney breast
This is looking over the top of the chimney breast at ceiling level, outside wall on the left, joist on the right, floorboards above
Looking over the top from the other side you can see there is what appears to be the chimney itself which at this level appears to be structurally separate from the visible chimney breast.
So my question is, how are these likely to be related/joined (or not) to each other? Is it likely to be possible to remove most of the chimney breast leaving the much smaller flue bit which is only 20cm x 4cm ish
Realise it might not be possible to say, but just wondering if anyone had come across a similar arrangement before
