Notes:
This McDonnell-Douglas illustration shows a “Power Tower” Space Station crew module. The original modules were 10.7 meters long with docking ports in both ends. They would have been assembled end-to-end in a racetrack-like configuration. Some engineers felt this could have created dangerous dead-ends inside the Station if a module had to be depressurized.
McDonnell-Douglas crew module mockup from 1984-85. The contractors paid considerable attention to habitability issues since each crew would live and work on the Space Station for 90 days before returning to Earth.
Rockwell's crew module proposal put all the equipment inside storage racks in the middle of the module rather than on the walls.
