Don't you think every little clue in the mansion fits together with the secret ending? My best assumption is that it belonged to the UEM, and he must have used the pods below to alter Xehanort's memory (to gain whatever he was aiming at). Though the only reason I doubt this is because the real Ansem Reports by Ansem/ DiZ said he lived there before the events of Chain of Memories. What's your guys' take on this?
