i'd like some feedback on the two windows, as I am currently looking at the same thing without windows. Why r they there given the expanse of glass on other wall. My mum had two narrow vertical windows either side and as they were un curtained they look like black rectangles at night which I found spooky. They didn't let in much light because of trees outside, but I guess if u had a skyline view say they may be useful. They also compromised positioning of artwork.

I wish to thanks those that have replied. I need the information on a "look a like" wall fire place, that looks like flame but is no heat. I have found a you tube that shows using a dvd player in a screen in a false opening that replicates a fire. I would like a commercially made item, and also the information to contact the company.

Ah, I wouldn't think so. Photo B is the external side of the chimney, which would have originally been outside the house (the external wall). So i'm guessing your living room was added onto the house at a later stage. So it was never designed to be a double sided fireplace, like some are. And yes, it is a structural part of the chimney. By the way, your bedroom fireplace is a beautiful original mantle, I wouldn't touch it.
