I don't recall that it was ever updated. Though I think there is one that is a photo copy of this plus the basement on the same page. The house has been added to and not followed properly in a lot in the scripts because generally the writers would not follow something like a floorplan when they write. For instance you can see on the plan that DW could not have a closet in her room and she could not see out a window of her room to the Molina's house. But there are lots of shows with a closet in her room.
Even though the house may not be consistent, I always like how the animators are able to pull off the house looking normal even though it's been changed dramatically.
The kitchen also has a mudroom ...sometimes.
When has this happened?
