I use Android Tiers, Glittertech (no surgery), and Rimatomics. My colonies always end up with just the most insane defenses with super powered androids.
Anyone who makes their way to my colony will find the most lavish place on the rim.

Not sure if it’s a vanilla thing but if you change the setting to rebuild destroyed stuff, it’ll also include the bills when the workstations get rebuilt.
Something like an insect hive will override the workstation blueprint and force you to restart, though.
