There was a rumor on a previous thread that those with their own bedrooms pay extra/rent for them? Not too sure about that though as Millie has had her own room since she was 13/14?
Luke and James share the red bedroom that used to have Jack & Daniel in it too. Not as big of an age gap as Tillie and Katie though. Chloe's make up room is now Daniel's bedroom in the basement - I think they only let her have it while she was studying but now can work from the salon so no longer needs it.
I do wonder if they have more rooms in the basement? As they used to have all the washers and driers upstairs in the old kitchen, but it was only when Sue got her 18kg that they suddenly had a laundry room in the basement. Within the last year they've also put a bathroom down there, which looked brand new so I'm assuming that it was just an empty room before? Before Chloe used it as her make-up room, what was in that basement room?
