Building passageways (5)

I believe the answer is:

halls

(Other definitions for halls that I've seen before include "''I dreamt I dwelt in marble ...'' (The Bohemian Girl)" , "Lobbies" , "Entrance passages" , "'I dreamt I dwelt in marble . . . . .' (song)" .)

I've seen this clue in The Washington Post.
