It is impossible for us to understand the Church if we regard her as subject to the limitations of human culture. For she is essentially a supernatural organism which transcends human cultures and transforms them to her own ends.
Houses mean a creation, something new, a shelter freed from the idea of a cave.
I think the thing to remember, though, the next time you hear someone who is really certain that he is on the side of the angels, is that the idea of angels was created by human beings, who are famous for being frequently untrustworthy and occasional.
