minecraft plans

so on my forever world i recently invited my boyfriend and we're going to build this huge fallout style bunker underground and it's going to be so cute but for that i need a lot of redstone because im planning on making it completely out of iron and wiring redstone lamps to levers to control the lights 

it wont be too hard considering i have a really awesome iron farm but for this build im going to have to build these farms in survival 

1. witch farm (for redstone, gunpowder, sugar) in order to power the lamps 

2. another iron farm (for more iron obviously) 

3. gold farm (either pigmen or something else idk) for the gold to build some redstone things and add a minecart system to the underneath of the vault 

4. villager breeder (to make more villagers for each thing) im planning on making a trading center that rotates through villagers using redstone for inside of the vault 

this is going to be pretty difficult to do because the gold farm will probably need to operate on a portal based system and the witch farm requires me finding yet another swamp with a witch hut so that i can experiment so i will probably duplicate my world into a creative world to test the ideas that i have
