Does everyone else make singular structures for their base, or make individual homesteads?
I pretty much always end up with "walled off community" for my bases. Housing usually ends up like multi-unit housing (i.e. one building with a number of rooms, but only residential), one complex for freezer, butcher, cook, dining/rec. Buildings over time for industry (i.e. about 5-6 production units per buildling), hospital unit, etc. I never plan terribly well for prisoners, so my prisons are usually just converted housing units from the apartment complex.
One mod that can help 'naturalize' settlement planning a bit is
Open The Windows - allows natural light and (with supplement mods) outdoor beauty to matter and they work as shootin' holes if you open them, but at the same time it makes your pawns more demanding of outdoor exposure and of beauty (if using outdoor beauty supplement). The three pics it has on the mod page do a good job showing what it does, honestly.
My perimeter wall usually has an entrance at 3-4 sides, with fortifications either just outside or at the wall. Not a fan (thematically) of trap corridors, myself.
I'm generally pretty terrible at pre-planning my settlements, though, so it's always a little different.
(Doing an accelerated tech start this time, seeing as the modscape is still fairly volatile at the moment.)
