Like the new Cluedo Harry Potter game, to mimic the moving Hogwarts giant staircase, it may be possible to use rotational wheels under the floor to change something. Obviously, the location of rooms wouldn't be possible due to the constraints of construction, but smaller things like curtained door frames, sliding doors, mirrors or windows could rotate or change position (or even smaller still - the floor or wall patterns which would be a very cheap and effective way of distracting customers from their conversations etc.)

Even using the prism shape of bilboards we use today to frequently change the screen could be used on various symbols on the walls - perhaps on the eyes of portrait paintings so it seems as though someone is watching.
