I finished my biodome!
It includes:
Obsidian Generator
NPC Rooms
Bedroom
Dining Room
Forest Biome
Armory
Glowing Mushroom Farm
Ultimate Crafting Station(No demon alter though :C)
Hellevator
Storage
-Potions/Consumables/Stars
-Blocks
-Bricks/Building Materials
-Materials/Seeds/General
-Ores/Bars/Gems
-Furniture
It is 100 blocks in diameter, I based the frame on the one I saw a few pages back. I was planning on making it 10x as big, but decided against it. (Although it would've been the best base ever, can house 10 different biomes, include a tremendous storage, hold many people and a whole lot of other cool things. [Meteor Head Farm, Arena, Garden, Swimming pool, etc])
