Alot of the things are already build in minecraft before(for example; pyramids, castles towers, huge trees), that doesn't mean other people can't make it aswell. They might have other ideas and it might turn out to be amazing in some other kind of way. I would love to check out BOTH of your residences
Yea, [ insert name here ] is soon wanting me to make him a Nether residence beside my Ender residence.
If you look on the live map pig and its close to your res you see the biosphere project.. They have the aether, the end, the mushroom biome, the desert biome, the plain biome, and many more! Also starring the Nether! You should check it out sometime
