Here are a couple of revised floorplans yet again.
One adds the new stairway down to the cellar, as well as the general location of the paddock, and the new dog yard.
The second maps out the cellar. You will notice "old stairs". These are from when the kitchen was directly behind the mead hall proper. Currently the old stairs are still there, but now they go nowhere. Where the corridor used to enter the kitchen is now part of the alder courtyard, with dirt fill and new grass. But it makes for an interesting feature nonetheless. It's what gives old homes their curiosity factor, eh?
Turns out the cellar is bigger than I expected. But one could say that it's bigger than Eodwine and his friends expected, but necessary because the old cellar was smaller and right beneath the kitchen; it made no sense to block off the old cellar, so the new cellar became an extension of the old. The fact that it never entered anyone's posts is just one of those things, I suppose.
