>>6132340This is roughly what I'm basing the build off of.
The rooms I was planning on doing were the music room and library kind of together (I started the inside of this one already), the attic with the killer bride, the dining hall, and the hall of doors with floating candelabra for sure. I also considered doing Escher's stairs and the stretching room as well. I definitely want the graveyard, the ghost horse carriage, and the hitchhiking ghosts included.
One idea I played with is building this on a hill to add some custom terrain and give it some height to put the graveyard as kind of like a basement on the inside, but I don't know how that'd work. I could also just go the diorama route and have the main building with extra vignettes next to it.
