In originally watching Dallas, I always assumed the kitchen was supposed to be behind the dining room. However, during season 6 I believe, you will see characters go through the door in the dining room, and then appear to go through another door to the right. Huh? Would this not add more length, that from viewing the exterior of the house, it obviously didn't have? Then, to add more confusion, in later years, it appears the back door that everyone always enters the house in, leads into the kitchen. I liked that during the earlier seasons, they at least seemed to try to make some effort to match the interior and exterior. The den/office was supposed to be through the French doors in the back, but that room was never seen again after season 4.
