A  building represents a collection of facilities scattered across a world that create  Jobs that generate different kinds of resources that are not suitable to large-scale resource gathering. If a world's population is completely wiped out (either by resettlement or warfare), all existing buildings are removed.

Building slots

Buildings are constructed in a colony's  building slots. A colony can have up to 12 building slots, although most of them are initially unavailable and the first one is dedicated to the colony's capital building. Additional building slots are unlocked by upgrading the capital building, constructing urban districts, researching technologies, and some civics.  Ecumenopolises,  Ring Worlds,  Hive Worlds, and  Machine Worlds start with all building slots unlocked.  Habitats have far fewer ways to unlock building slots than other colony classes, and can't normally unlock all 12.

Planetary build speed

The  planetary build speed modifier reduces the  time it takes to construct all buildings. This modifier can be very useful, as it also affects building upgrades, and higher level buildings often take longer to build. Note that this modifier actually increases the rate of construction, thus a 100% increase in build speed is equal to a 50% reduction in build time.

Capital

The capital always occupies the first building slot and provides some of the basic housing, amenities, jobs that reduce crime and spawn defense armies, as well as other jobs which vary depending on empire authority and civics. Upgrading the capital is one of the ways of unlocking additional building slots. Capital buildings cannot be demolished, downgraded or disabled, and will automatically be converted to the appropriate type if traded, ceded, or conquered by another empire with a different authority or if the planet designation is changed.

Capital tiers

Capital buildings can generally be categorized into 4 tiers by which technology unlocks that tier, what other buildings require them, and the max general productivity bonus that they can apply. The standard capitals line up on these criteria neatly, however other types do not. With  Nemesis, the Galactic Emperor can upgrade their capital planet or habitat with a "fifth" tier imperial capital building.

Capital tier	Required technology	Job Productivity
		Output	Upkeep	Required technology
2	Planetary Government	+10%	+10%	Improved Production
3	Colonial Centralization	+20%	+20%	Efficiencies of Scale
4+	Galactic Administration	+30%	+30%	Maximized Productivity

Tier 4 and imperial capitals convert one tier lower, other tiers convert directly except as noted below.

Standard capitals

The standard set of capitals are built on planets without a special designation as well as ringworlds by non-gestalt empires.

Habitat capitals

Habitats have their own capital buildings, which are used by all empires. If the Galactic Emperor has a habitat as their capital, they can upgrade the capital to the respective Imperial capital. Habitat Administration counts as tier 2, except for job productivity, for which it has no bonus. Habitat Central Control counts as tier 4 for building requirements and tier 2 for job productivity.

Special designation capitals

Resort Worlds and Thrall Worlds have their own unique capital buildings. For each designation, the basic capital acts as tier 2, except for job productivity, for which it has no bonus; the upgraded capitals convert as tier 3 and count as tier 2 for job productivity and as tier 4 for building requirements.

Hive Mind capitals

 Hive Mind empires only have two regular capital buildings. The Hive Core is tier 2 for all purposes, except that it also converts from tier 1 capitals. The Hive Nexus acts as tier 4 for job productivity and building requirements, but converts to tier 3.

Capital	Produces	Jobs	Upkeep	Cost	Requirements

Machine Intelligence capitals

 Machine Intelligence empires have the same four capital tiers as regular empires. Capital conversion works normally, except that the Administrative Array (tier 2) will convert to a Reassembled Ship Shelter (tier 1) if the planet is conquered by a non-Gestalt empire. Also, the Planetary Processor (tier 3) counts as tier 4 for building requirements.  Driven Assimilators' capitals have one less  Replicator and, after tier 1, one more  Maintenance Drone than other  Machine Intelligence empires' capitals.

Buildings

Regular buildings

Each regular building has up to 3 tiers, which determine its number of jobs, upkeep, construction time and cost. Tier II and III buildings also require a certain strategic resource for construction and upkeep.

Tier	Jobs	Monthly upkeep cost		Building cost
		Energy	Strategic resources	Time	Minerals	Strategic resources
I	+2	−2	0	360	400	0
II	+4	−5	−1	480	600	50
III	+6	−8	−2	600	800	100

If a world is conquered by an empire that uses a different set of buildings for the same primary resource, the existing buildings will be converted into new ones of the same tier. Tiered buildings cannot be constructed on Thrall Worlds.

Primary resource	Tier I building (2 Jobs)	Tier II building (4 Jobs)	Tier III building (6 Jobs)	Jobs	Strategic resource	Requirements

Housing

Housing buildings provide  Housing and come in two tiers. The advanced resource used to upgrade their tier is  Rare Crystals. If the world is conquered by an empire with different government each housing building will be converted into the equal tier counterpart of the new owner.

Gaia Seeders

Gaia Seeders can only be constructed by empires with the  Idyllic Bloom civic. Building and upgrading Gaia Seeders takes 480 days for each phase and requires a tier 2 or above capital and the following planet classes:

• Initially, the planet class must match that of the primary species' homeworld. Upkeep on such worlds is not increased.
• If the  Terrestrial Sculpting technology is researched, the planet needs to match the climate of the primary species' homeworld. Upkeep on such worlds is increased by +25%.
• If the  Ecological Adaptation technology is researched, the planet can be of any class except  Tomb World. Upkeep on such worlds is increased by +50%.
• If the  Climate Restoration technology is researched, the planet can be a  Tomb World as well. Upkeep on such worlds is increased by +75%.
• Gaia Seeders cannot be built on planet classes that cannot be terraformed (Gaia, Ecumenopolis, Hive, Machine, Relic, and artificial worlds). If the world is terraformed into such a class, the building is removed.

Military

Military buildings produce defense armies and are vital for the protection of a world. Once constructed they will always be placed at the top of the buildings order to be the last buildings destroyed by orbital bombardment. Fortresses can also contain an FTL inhibitor if the  FTL Inhibition technology has been researched. Upgrading Strongholds into Fortresses requires the  Global Defense Grid technology.

	Building	FTL Inhibitor	Regular jobs	Capital tier	Upkeep	Cost	Description
	Stronghold		+2 Soldier/Warrior Drone	1	−1	240 400	A planetary stronghold housing a substantial garrison force to protect the world from invasion and rebellion.
	Fortress		+4 Soldier/Warrior Drone	2	−1 −1	360 400 50	A massive fortress complex with an expanded garrison and training facilities for soldiers.

Law enforcement

Law enforcement buildings produce defense armies and  Unity and, most importantly, reduce  Crime or Deviancy.

	Sentinel Posts	+2 Hunter-Seeker Drone	−2	360 200	Gestalt Consciousness	These are the outposts from which Patrol Drones scan the Consciousness for signs of deviancy and malfunction.

Refineries

Refinery buildings produce strategic resources. They are less efficient than the extraction buildings that require planetary features, but refineries can be built on planets without those features. They cannot be built on Resort Worlds, Thrall-Worlds, or Crucible Worlds.

	Building	Jobs	Upkeep	Cost	Requirements	Description
	Chemical Plants	+1 Chemist/Chem-Drone	−3	480 500	Volatile Material Plants technology	The unpredictable and sometimes unstable Volatile Motes are produced here artificially. No open flames are permitted within a five kilometer radius of the plants.

Trade

Trade Buildings create Clerk and Merchant Jobs, which generate Trade Values and Amenities. While Clerk Jobs have a poor yield of only 4 Trade Value per Jobs, Commerce Buildings provide a significant number of them. Upgrading Commercial Zones into Commercial megaplexes requires the  Interstellar Economics technology.

 Gestalt Consciousness empires do not have civilian trade and cannot build these buildings. They also cannot be built on Thrall-Worlds.

	Building	Jobs	Upkeep	Cost	Description
	Commercial Zones	+3 Clerk +1 Merchant with Commercial Enterprise	−2	360 400	These commercial zones are home to towering office buildings and business complexes.
	Commerce Megaplexes	+6 Clerk +1 Merchant without Commercial Enterprise +2 Merchant with Commercial Enterprise	−5 −1	480 600 50	Great commercial spires and towers rising up towards the sky, blotting out the light.

Organic safekeeping

 Rogue Servitor empires need organic safekeeping buildings to provide  Bio-Trophy Jobs for  Unity. These buildings are converted into  Housing buildings of equal tier if the planet is conquered by an empire that lacks the civic. Upgrading Organic Sanctuaries to Organic Paradises requires the  Idyllic Architecture technology.

	Building	Jobs	Upkeep	Cost	Description
	Organic Sanctuary	Bio-Trophy +10  Artisan Drone +1	−2	360 400	This sanctuary provides a sealed environment where organics can thrive in a safe and above all controlled manner.

Fallen empire

Fallen Empire buildings are found on the homeworlds and planets of Fallen Empires. These buildings use incredibly advanced arcane technology, and as such are exceptionally effective compared to regular empire buildings. Most are autonomous, and can be used by other empires if captured. Ruined Fallen Empire buildings can be repaired. Fallen Empires, awakened or not, can never build more Fallen Empire buildings (with a few exceptions), making these buildings highly valuable.

Using the Reverse-Engineer Arcane Technology artifact action has a small chance to allow the user to build a Fallen Empire building on one of their planets. Each building takes 480 days to construct. If demolished however, they cannot be rebuilt.

	Building	Produces	Upkeep	On Capture	Description
