It could be done right this second with three modules. One ten meter center truss with a docking port in it's center and rope/cloth/woven ladders going down both sides. This can also hold battery packs and solar panels backed by radiators to manage heat and generate power. The other two modules are identical ten meter long, say 3 or 3.5m wide habitats, this would make them five decks assuming a deck is ten feet tall. Small rocket motors (you could even make them solids) can set this dumbell station spinning at 4rpm which will develop about .25g on deck 5. This is probably more than enough to preserve human health on the station indefinitely, especially combined with regular resistance exercise and pressure garments. If you added two more central booms and made a station 50m in diameter, with an rpm of 4 you could easily develop nearly half a g.

See pic related, maybe not as ambitious as a von Braun torus, but it would serve as a cheaper, smaller alternative for non-government projects and as proof of concept.
