Crazy question, I know.... bear with me a sec. I've been on test just now and confirmed that I can make a 3 level home with no floors ('cept the ground, duh) - in order to create the feeling of a high castle with stained glass windows on the West wall of an 18x18. The one I made on test had different types of walls for the 3 floors, and you can stand on the ground floor and look up at all 3 sets of walls. I can't remember ever seeing anyone do this, but - if you have - I'd really love to see a pic or tell me where one is... I'm sure I can't be the only person to want to consider this, so there must be some examples I could take a look at for "inspiration".... If I don't have a char on your shard, I'll make one - np.
