Tech tier 

Media Conglomerate 

+1 credits/sec 

+2 Influence points 

A few are a must have so that you can unlock the strongest abilities of minor factions.

2 Civ 

Commercial District 

+25% 10% commerce income 

This affects only planetary credits and comes rather late in T3. Still worth it on Terran planets with maxed commerce. 

3 Civ 

Fulfilment Warehouse 

+1 import export point 

+1 credit trade slot 

A flat +2.5 cred/sec income increase. 

3 Civ 

Translates to 2 credits/second, as long as you have allocation slots

3 Civ 

Orbital Mining Control 

+50% metal & crystal from extractors 

Note: only asteroid mining is buffed, not planetary mining. So, check how many extractors you can actually build. 

3 Civ 

Alloy Foundry

+3 metal trade capacity

Niche item, when you have lot’s of trade ports, but no allocation slots for metal

2 Civ

Synthetic Crystal Farm

+3 crystal trade capacity

Same as Alloy Foundry, but for crystal

2 Civ

Garrison Command 

(TL ONLY) 

Spawns 125-500 worth of supply from factories, depending on your tech level. 

Garrison ships can jump to adjacent planets. This does NOT use your supply limit, but you do require a factory on the planet in addition to the planet module. 

You can build heavy cruisers with an upgrade. 

2 Mil 

Center for Human Doctrine 

(TR ONLY) 

+10% weapon damage for 300 seconds 

This works for defense and offence. 

2 Mil 

Munitions Plant 

+50% dmg to all structures and starbases 

Straightforward defense buff.

3 Mil 

Command Bunker 

+1500 planet health 

+10 orbital slots 

Planet health will take time to regen, but +10 orbital slots can be quickly converted to 10 extra turrets. 

2 Mil 

Coalition Outreach Center 

+30% culture rate 

+3 Influence points 

Unless you struggle to give out Influence points you should work with Media Conglomerates instead.

3 Civ 

Civic University 

+2 civilian research points 

+1 civilian orbital slot

If you have no more big planets around you, this can be a life savior for research progress.

Military Research Base 

+2 military research points 

+500 hit points 

Same as Civic University but without an orbital slot. 

Regional Government Office 

+0.5 credits/sec 

+2 civilian orbital slots 

Civic University has 1 per planet limit so you cannot spam it for orbital slots. Use this one if you need more building slots.

Industrial Complex 

-20% ship build time 

-10% ship cost 

Extremely good on a forward planet to pump out ships. Sadly, you will need T3 civilian for this one first.

3 Civ
