I design my new (initial) star-base at new colonies to be bare bones. Components for three construction yards, docking bays, reactors, fuel storage, and med/rec facilities. Then I design, as sitrep develops, a variety of upgrades to this bare bones star-base. Some go heavy def, some lite defense. I find it important to get a basic star-port up and running to get the colony plugged in. Even in hostile areas, this seems to work better (just need a decent flotilla paroling the colony).
