In one corner of my bedroom, the corner sticks out. Almost like an iinverted corner. I don't know if it is structural or just was done to add decor but I want the corner to be square. Any idea why that would have been done? I'm tempted to cut a hole in the wall but don't want to if it can't be changed. Any ideas? I can send pic if anyone can help.

Hi Everyone, My wife and I are finally 95% complete with removing all of the plaster and lath from an 1880's home. Yes, I know sacrilegious but there are plenty of reasons, one we are moving walls for rooms so we really could have only kept outside walls anyway. Two, I really wanted to insulate and wire properly. And third, there was paneling everywhere so the plaster had tons of holes and cracks from nails. Anyway, I was always planning to remove the plaster ceiling (on the second floor) but now I'm second guessing that and am wondering why not just leave it? I do want to install drywall, but why not just drywall over the plaster? I'm thinking the only con to this is possibly a less "perfect" finished drywall result with possible waves. But lets face it, the house is balloon framing and 130 years old. The drywall won't lay perfect anyway and that's part of the character of old homes. Oh, and I guess another would be about an inch less of ceiling height. Not a problem though because they are already 8'3". The pros to leaving it, as I see it, 1) Less mess and time - walls are bad enough to tear out. A ceiling that has access from the attic will mean everything that has accumulated in the attic for years will fall on my head. 2) Better insulation - granted I'm sure it won't add much, but more material must be better than less material for insulating. 3) stronger "fall" protection from the attic. Plaster and lath at least has a little strength compared to drywall alone. I know it still breaks (from experience), but you're not likely to completely fall through. Can anyone suggest whether this is a good idea or not? Maybe someone has experience dry walling over plaster? BTW, the wiring and everything is accessible under the floor boards in the attic and they are relatively easy to pull up. Thanks for your help!
