The Pink Palace Floor plan Ruff Draft

Did I mention that I was a drafter? Oh, well I am. I decided to draw up blueprints based on the Pink Palace in Coraline. I found as many reference photos of the Old Victorian home that I could. I then imported the files into Microstation and scaled the photos to 'scale'. Here is a ruff draft of the first floor layout plan. Here's my problem. I cannot get the ext. shots of the house to match up with the inside shots. The house just doesn't seem to match. I labeled where each room is as far as I can tell. The kitchen is seen with two extra windows from the outside, that are not seen on the interior shots. The scene near the beginning of the film, where Coraline comes in seemingly from the back door, and drops her raincoat on the hall floor, is also inconsistent to the layout, as that hallway does not exit to the outside of the house. Not to mention that the main room with the 'boring blue boy' and little door also doesn't match in overall shape and window layout. So, as far as I can tell, either the Pink Palace was redesigned since the reference photos where taken, or the intr. shots never where meant to match exactly with the ext. of the house. Or I am way off and totally misinterpreting what I am seeing. I think I am going to have to redraw the layout based on the interior shots later and post that so you can see the difference of that I am seeing.
