I suppose I'd call what I do a "mill and factory" architecture which seems to be similar to yours.

I'll find a resource site - take for example the infamous now-nerfed cliff in the west Northern Forest, and I'll put an iron mill there that does everything from smelting up to, say, reinforced plates or modular frames. Same with steel mills, refineries etc.

These will feed a small number of major centralized factories. One that I'm in the process of building the 1.0 version of now is always located in the southern Rocky Desert that I call the Desert Automated Manufacturing Node...In my Update 5 playthrough I amused myself by giving all my facilities rude names with technical sounding acronyms, and the DAMN stuck. I still call it that. It's the mid-game factory, it makes motors, crystal oscillators, heavy mod frames, circuit boards, AI limiters, high-speed connectors, computers and supercomputers. Big factory that takes up most of the big empty section of the biome. It, along with the late game (radio control units, turbomotors etc.) and now the quantum process factories will ship goods to the Project Assembly Tower where the space elevator lives.

My nuclear power plant is as self-contained as possible; I don't like pulling from main production to feed power so it gets a whole weird mishmash factory unto itself. This ended up being the only successful sushi belt in my last playthrough, as I needed several kinds of things in fairly small amounts.
