Here comes the finished "Great Ohiroma" (audience hall) level in all it's glory :-)
I have built it with an official main entrance and some hidden doors on the side, which I just cut manually. The area where the Shogun/emperor/lord is sitting is raised a little (not sure if one can see that in the photo).
This will conclude the construction phase of the set. Now I will go into production phase, checking everything and making instructions.
