When I lived in the UK I had:
entrance hall
boot room/gun room
library/morning room (that's what a poncey estate agent would call it but we just called it the study or the little sitting room.)
drawing room (and we really did call it that, to distinguish it from the....)
TV room
A pantry
A conservatory (the O word never entered my mind)
A utility room (although we would have been within our rights and technically correct to call it a scullery)
Back stairs (for the staff, darling)
attic (a proper one with stairs and windows, which also doubled as 'bedroom 7' and would have once been servant's quarters)
Outbuilidings assorted and various, including:
boilerhouse
woodshed
and the jewel in our crown was a crumbling, half derelict Coach House.
Ta-Da!
These days I live in a modern rented house but it has a maid's room with an actual maid in it, so I win.
Actually I probably lose, don't I? I have a gym and a pool as well. And a deep coloured feature wall.
OK, I definitely lose. I am the biggest loser.
