Did you put a vent in? Trying to work out if it needs it. The chimney still functions from the fireplace in the room below and would like to keep it that way so presume need to make sure my bed won't burst into flames.
breast's redundant now so didn't consider putting a vent in. we could have removed the full chimney breast I guess but that's an even messier (and more expensive) job + means we have some nice recessed shelving in the alcoves on the lower floor
that's what we did. messy job but worth it to make the room more usable as a double
