All I can really say is that the playroom should be nowhere near the library or chapel...kids make too much noise. Their bedrooms should be pretty close to the parents' room. I'd put the playroom in a corner to have windows letting light in so the kids won't be knocking over candles and burning the place down. I'd put the music room in another corner again for light. Storage rooms could be used to separate any room from another, like closets or something. Just some ideas, my 2 cents.
