As said before, the measurements aren’t going to be correct, I went with the positions and shapes of the rooms as best as I could.
For some reason, Madison and Zoe has a whole walk-in closet, while Misty and Queenie stored their clothes in basically, a cupboard. Fiona’s dresses were lined up against her closet wall, so I figured it was longer than deeper.
Also fun fact, continuity errors! It’s a fact that Cordelia’s room has two doors, and that they’re the only ones on that side of the hallway, and yet, Marie Laveaux is seen exciting her guest room through one of those doors. Cordelia has side windows, BUT Marie has a room (as seen when Nan fetches her baby) that’s FARTHER than Delia’s, with its OWN SIDE WINDOWS. So technically Marie’s room should be glued to Delia’s, and there should be three doors, but it can’t physically be when there are windows in Delia’s room and no third door. So for the sake of my own sanity, I just ignored that guest room. If you said it was there, you wouldn’t be completely wrong.
As you can see, question marks! There are no shots given in to those rooms, so I’d guess guest rooms for the council. I wouldn’t mind saying Myrtle stayed in the one mirroring Delia’s.
It is also not shown where the drop down stairs to the attic are located.
EDIT: A wonderful anon reminded me that Cordelia does in fact have her own bathroom and closet. If walking into her room, they’d be on the left side, closest to the stairs, with a door for each. Thank you!
