This makes me think there were three windows in this space, originally. The big window in the dining room is the same.
After determining we need professional help (feel free to take your shots at that one!), the skim coat is up and will be ready for paint TOMORROW! Cannot wait- we're so close.
The rough coat is up on the other side of the new wall as well. John had this patched in just about 45 minutes. It would have taken me days to get as far as he did!
