(Building off my previous post!)
So with further experimenting, I was able to make a loft that could be slept on–AND low enough that the new stairs can be connected to the troupe stage.

I’ll probably work with a futon in a bit, but I’m almost fairly certain it’d be possible to mostly hide it.

I’m in a private house, the loft trick only works on windows and doors, but the FC door is still ‘there’ kinda even though I’m in a private house. The placemet zone is actually WAY bigger? I could force different heights with the bed and stage with more leeway.

Unlike the front/side windows, the placement zone of the lofts is actually fairly big.

Actually pretty much anything I tried worked on that spot too. (I’m kinda sad I couldn’t get my poor Ananta NPC up higher, it would have been so cute to have her just chilling in a loft hot tub)
