Recicled sets

Has anyone of you chaps who has seen "House of Usher" noticed that this film here uses the same sets? The entrance hall, the living-room, corridors, staircases and so. I am not criticising it; on the contrary: those are fantastic sets that create a great Gothic atmosphere, and it is nice to see them again in this film.
Recycling out of necessity can, sometimes, make another masterpiece.
One of the best Poe-Corman films, definitely.
