I have an old house (1850) that was built in "stages". The front part is from 1850, the middle part from maybe the late 1800's and the back part from maybe 1920's. My daughter's room is in the middle part and runs the whold width of the house. The ceiling is a normal height starting on the right side of the room and going about 2/3 of the way acroos. Then it angles down to the top of the 2 windows on the left side of the room. If you look at the house from the outside, the roof pitch is the same on the right & left side. There is no access to any attic space inside and this room is on the 2nd and last floor of this part of the house. We do know there is some space above the ceiling, though, since when we moved in we had racoons living up there and we could hear them move througout the 3 sections of the house (they are gone now!). Any idea why there is this weird ceiling angle and how can we find out if we can make it the same height all across?
