Design / structural advice

[Jude3003]

Hi. We have now completed our extension and have moved on to the existing 1930s build house. We have knocked out the wall between living and dining room (No rsj required as it's not carrying joists) but as you can see from the pictures we are unsure what to do with the 2 beautiful arches we are left with. In a perfect world we could knock the centre out and have 1 big arch as a feature but we are unsure weather the wall between carries the chimney in the room above the left arch (no chimney in room above right arch). Has anyone seen this before? After completing the extension funds are low and another structural engineer and RSJs are out of the question.

Looks to me like the wall is supporting joists from above, as the laths on the ceiling run parallel to the wall. so the wall is structural. If you can't afford a structural engineer and a bit of steel you will need to leave this as is.
