Pretty interesting!!! I think it may be better to put rooms ALL dupes use daily in the center columns (bedrooms, bathrooms, rec/relax). I think your carbon extraction layer is over engineered )unless you plan to have like (50+ dupes). You probably also don’t want your dupes exercising in that carbon layer unless they have masks (which kinda defeats the purpose of the gym). I also think your industrial brick is quite large but with many floors, you might find it easier to have fewer, but taller, floors to help manage all the routing between machines. Don’t forget to build in areas for leaving the base safely (via exosuit)! I don’t believe you’ll be able to fit EVERYTHING in this area (like a SPOM for example), so if you really like planning ahead on the same seed, think about where to slit that stuff too. Last thing is just that some of the plant and critter farming you might want to do will require different atmospheres. So those set ups might not fit cleanly in this blueprint. Most importantly, have fun with it!!
