I never knew there was such a thing. Doubtful that the CLeavers live in one, but maybe the Andersons.

Interesting video. Could be. I've always liked the interior set design on FKB, although there is a mistake in Jim and Margaret's otherwise-nice master bedroom. The door to the right of Margaret's dresser seems to enter right back into the hallway. Otherwise the layout is great, and matches well with exterior shots.

As for LITB, I think the first house could be a Sears house, based on the exterior look.
