The last in these posts on 'how to' make the palace interior. This one is about planning the room out. Yes this should have been number one, but to be honest I didn't draw up proper plans for the other rooms, just jotted down bits on post-it notes as I went along. Really it is suit yourself with the planning, general idea is :
a. Write out a list of features for the room.
b. Sketch a view or views of the room, with some ideas jotted on it.
c. If needed draw plans of sections which require it with measurements, to enure you cut the parts up right for assembly.
I've started keeping a modelling ideas book, so I can jot/sketch things in as they come to mind.
Below is a sheet with the sketchs for the dual purpose Ballroom/Throneroom (click on it to see in full size)
