I actually expanded the base because I ran out of room! My brother-in-law, a War History expert, among many things, is also a collector of High Elves, but I wont hold that against him. He was surprised when he saw the solid castle protected on its west side by little more than a garden wall! (As the original plan shows) I replied saying "The castle was on a steep hill!" Not long after, I saw his reasoning and added an extra "Extention" roughly another fifty percent to the castle!
