if you want a great space that makes best of all its uses, check out the Cutteridge Estate.
has 2 floors...like 10 spereate spaces not including the whole of the outside or the one mysterious room you cant get into(or the basement you cant get into)
it is done up like a real house with real walls.
plus there is all the mystery that is all around the space with all the fun things to explore.
and then there is the game in it as well.
i agree that Rapture Apt is a great space(it is one of my favs i use as my goto personal space)
but Cutteridge Estates is right up there as well
