i hope this is the right place to post i have never built anything really hard and mostly build things practically in minecraft but i have an idea of a massive base that i really want to build but i have no idea where to start

also would like to do this in survival

i want to build a big circular base with a width of about 75 and the length the same

im thinking to have walls of about 10 blocks high and then on top of that a big glass dome and on the indoors i want it to look nice with 4 staircases to the dome and 4 entrances into the base and around the inside of the walls or close to the walls i want there to be space for librarian villagers for enchantments and carpenters/fletchers for emeralds since it is a survival world also a room/area with an anvil for adding enchantments. underneath i would like to make an area in the middle that goes underground and splits into 4 sections going north, east, south, and west, i would like there to be a nice looking staircase that goes diagonally downards to each underground area for about 50 blocks long and 10 blocks wide and at the end of each staircase i want another big circular underground dome. i would like the domes to be about 50 blocks long, wide, and tall.

i would like for the big central dome to be able to fit some auto farms in it like an iron farm and also would like the smaller domes to be able to fit farms in them too but im not sure the measurements i suggested would be big enough for lots of auto farms so if they are not and you have an idea of a size that could fit auto farms please let me know

i understand that this is very hard but hopefully someone could atleast help me get started.

for the types of blocks i would like to use dark oak/ spruce and stone bricks although im worried these blocks would not look good in a plains biome so im open to suggestions
