Hi - currently breaking outafireplace in circa 1900 terraced house and feels like a bit of an opening disaster…. What you can see is where I have removed what wasn’t (or didn’t look like) original brick work under the plaster. I expected to find a lintel or archway, but all I’ve found is poor brick inside at odd angles and trying to work out what’s what. I don’t want to go too high - anybody come across anything like this before?
