Not much more to say really. Its inside the house, not just the courtyard or barn. Didn't bother me too much since I figured you'd find out eventually but a friend who takes housing more seriously messaged me about it.
Hopefully ZOS fixes this soon but if anyone wants a temporary work around apparently a couple of structural floors clipped in above the ceiling stops it. She suggested "Solitude Floor, Ornate Tile"
I've had the house since the week housing came out so I'm pretty sure this is a new problem.
