This may have been discussed before, but years ago, I remember noticing that the house set used in the b/w episodes had a similar look to the house set from All In The Family?

Not really, the front door of the Bunkers was to the right and Lucy's was in the center.

I had never thought about it, but now that you mention it, I can see a general similarity. In both cases, to the left of the front door is a closet. To the left of the closet is a similar-looking staircase. To the left of the staircase is a round dining room table. And to the left of that, a swinging door leading to the kitchen. And I think both have a window between the living room and kitchen with louver shutters.

Thank you. Your examples are the very ones that caught my attention when I noticed that they had similar looks.
