 CONT: Between Season 4 Episode 10 and Season 5 Episode 1, the layout  of the interior of the house changes. Formerly, standing inside the  living room, there was a wall outside the living room door, which  the door opened from the right. Now, the door opens from the left,  the wall is gone and you are able to see the front door of the house  from the living room. In Season 9, the door opens from the right  again.
