I am not sure.. Clouseau is using two time the word villa in the current source on my hd. However I can't imagine that we Olaf or me used this word there. Maybe it was Olaf he is firm in language and did all the texts (or atleast "translated" my "english" into propper "voicing").. I got in major trouble with my kind of expression and talkstyle I gave many of the characters. So it was much to simple in the raw versions.. I am programmer and no highly social conversational mastermind or something. Actually we meant the mansion, however we play a lot with words even these rather complicated "riddles". I just looked it up for you:
"In simple words, you can say that a villa is designed for a single family while a mansion is there to accommodate multiple families, thanks to its gigantic size."
