Mine is definetly a simple 9xwhatever, then I put a ledge around it, and now, with this new update I can add stone walls too it, I have also made courtyards, basically little gardens. Some people have told me it's not worth it too mmake a castle, but this is nowhere near true, castles may just be for looks but they are definetly worth it. Please, add detail if you want, the more the better.
