Space Colony
These are not small circular living quarters mounted on the axis of a spaceship.
Instead, they are similar to the Rotating Wheel Space Station of Elysium and Startopia, and the O'Neill Cylinder Colony of Gundam and Interstellar.
The "assembly kit" for such a mega-structure for semi-permanent human habitation could be like startopia with different decks, eco-storages, or industrial zones, but with the obvious advantage that ------ could fit all the previous construction kits in, and claimed that "This is for the preservation of human history".
