Freeport Maps include up to 208 floors, which we will group here when we hear anything about them. There are 103 “east” floors, which are filled with a human-compatible atmosphere, and 105 “west” floors.
Each floor is about 20 feet high, except the docks are taller. 2 Elevator columns form the spine.
When the station is in long-term orbit, it spins around the port, giving variable gravity between 0G and 1.2G at the perimeter.
(All West levels have non-Oxygen atmospheres, primarily Hydrogen-based.)
