Wolfie,
The room on the left facing the house (staircase room) is 11" (deep) x 9 1/2 wide` the stairs stick out from the wall about 2 3/4 inches. The room on the right with the bay window is 11"deep not counting the bay , and about 8 1/2 wide, the room upstairs is the same dimensions as the bay room. Hope that helps.
It's hard to tell from the picture but while looking for something else I found one that looks like it could be a coordinating pattern.
