Since I'm attached to my home shard's house design, I like to fiddle around on Test Center and try out new layouts and decorations. This is the result of some of that messing around. If I were to build this again, I would place the pink stone walls differently to help the entire design flow more. I would also do something to make the 3rd floor flow better, but it'll do for now.
