I see the Space Station Jefferies configuration as highly modular, and somewhat related to the same design philosophy of Federation starships. Just as a Constitution-class starship employs a primary hull with a bridge module on top, a secondary hull and nacelles interconnected by fin-like pylons, so Jefferies features a highly sectionalized modular design. The large ring hull of the Jefferies appears to have 15 segments that form a rough circle that reminds me of the Pentagon building in Washington, D.C. I see this as a practical way to build such a large structure, a way to incorporate a diversity of organizational departments into the overall station, and also a way to protect the station's inhabitants in the event of system failures or hull breaches. The rings remind me a little bit of the saucers used in starships. It's a vaguely similar principle. I like and respect the work being done in this thread, and the work Mr. Jefferies did in his original concept drawings. I would love to see a different station concept that would use common TOS hull shapes and variants in very different ways as well.
