I have read the thread on Domus optima, but I am looking for the idiom: how did Romans title their houses (vs. describe them)?
In English, I would title our place "House of the Large Cups" because that's what everyone remembers about it: we have huge coffee/tea mugs. If a Roman was to do the same, how would they bestow a fatuous sobriquet so they could put it on invitations as a private joke with their friends?
