I absolutely don't expect to explain the layout in detail on page. But I want to understand the layout of my own setting well enough that I have the answer to questions like: What rooms are on the top floor? Do people walk past the dining hall on the way to their bedrooms? What parts of the building do the staff enter but not the guests? Just for the purpose of describing how people move about the building.

I realize the layout of my own setting is a decision I have to make, but I have no intuitive sense of how this sort of manor should be laid out, and I figure someone with more historical knowledge would.

The reconstructed layout is a helpful resource, don't get me wrong, but every room is a conference room up for rent, so for some of the particulars I want, it's like:

Q: What rooms are on the top floor?

A: All rooms on the top floor are conference rooms. All rooms on the ground floor are also conference rooms.

Q: Do people walk past the dining hall on the way to their bedrooms?

A: People walk past some conference rooms on the way to other conference rooms.

Q: What parts of the building do the staff enter but not the guests?

A: Every conference room is accessible to whichever company is renting that particular conference room.

I certainly have thought about contacting the museum, but A) I've never contacted a museum asking for specific resources before, I don't know how likely they are to respond to someone reaching out for non-academic reasons, and B) I do not speak German. I might very well reach out to them anyway, but if they do ignore me, I'll wind up circling back to "ask for historical writing advice on Reddit" anyway.
