I'm not sure what you are asking. If you have made a box grid for your home and you have a piece of the house that doesn't seem to "fit" in it, it is still in a "direction" location of your home.
You can check out:
Level Two, P.48-49
Level Three, P.11,16, DVD "Extentions" special feature
and we'll address it further if it doesn't answer your question.
Much Love, Shawn
