Moin, I'm currently building a huge Minecraft base. So far I have a 100% invisible entrance where nothing has to be placed to open it. An elevator at about level 10 and a security gate. Then I have a room with a magic table, workbench, etc. And a fully automated warehouse with all items and farms for every possible item with a connection to the storage system is planned. Then I still need a bedroom, have I forgotten something important that a man needs because in the base there should really be everything in the best, most beautiful and most effective execution. I will switch to adventure mode later on.
Eat
Enchantment Books
Magic table
armor
Coal / fuel
Building material (stone, wood etc.)
Everything still looked pretty blatant until I mentioned that you were in creative mode… But well, build a villager farm
Each one his. But villagers are never a good idea
An iron farm would still be cool, in theory you can also automate wood farms and quarry stones
