The factory comprises of 3 floors and each of the floors has 4 wings with multiple rooms of varying sizes. The interior is fully lit up. There is staircase access to the upper floor and an area within the center that is for an elevator creation of your design. Consider it a mini challenge of sorts and part of the progression of the modpack.

This is a base you are going to have to work towards. Once you have some of the early game mechanics in place, like crushing wheels, press, whisk, crafters etc you should consider moving into this factory to expand your automations.
