Branch Offices

A building provides variety of jobs that generate different kinds of resource that are not suitable to large-scale resource gathering. They are limited by the planet's population and capped to 16 buildings at 75 pops, with the first slot always being occupied by the colony's capital building. Each additional 5 pops unlock a new building slot. If the number of pops falls below the number required tor a building slot any constructed building will go into disrepair and stop producing jobs. If a planetary population is completely wiped out (either by resettlement or warfare), all pre-existing buildings will be completely destroyed.

Planet build speed

Planet Build Speed is a modifier that lowers the building time for all buildings. This modifier can be very useful, as it also affects building upgrades, and higher level buildings can take longer to build.

Colony capital

The Colony Capital always occupies the first building slot and provides some of the basic housing, amenities, jobs that reduce crime and spawn defence armies, and other jobs which vary depending on empire authority and civics. Many other buildings require a sufficiently high-level capital building before they can be built or upgraded, which gates your colony's development. Capital buildings cannot be demolished, downgraded, ruined, or disabled.

Standard capitals

The standard set of capitals are built on planets without a special designation as well as ringworlds by authorities. The base capital provides Colonist jobs that produce food and amenities to assist with the initial upkeep of a newly settled colony, they are removed upon upgrading.

Hive Mind capitals

Hive Mind empires only have two capital buildings. They are the equivalent to the level 2 and 3 capitals of other empires for conversion purposes, even if the world previously contained a level 1 or 4 capital.

Machine Intelligence capitals

Machine Intelligence empires use buildings similar to regular empires and will convert to or from them if a planet is conquered by an empire with different authority. The number of jobs offered depends on whether the empire has the Driven Assimilator civic.

Unity production

Unity buildings create Jobs which produce mainly Unity based on an empire's government. Until 2.6, each building could only be constructed once per planet. If a planet is conquered by an empire with a different government the Unity building will be converted into the same tier equivalent of the new owner. Spiritualist buildings also cause +5% ethic attraction per tier. None of these buildings can be built on a Thrall World.

If an empire is any degree of Spiritualist and has Corporate authority it will use temple buildings.

Tier	Building	Spiritualist Building	Corporate Building	Machine Intelligence Building	Hive Mind Building	Jobs	Upkeep	Time	Cost

Trade

Trade Buildings create Clerk and Merchant Jobs, which generate Trade Values and Amenities. While Clerk Jobs have a poor yield of only 2 Trade Value per Jobs, Commerce Buildings provide a significant number of them.

Event buildings can only be obtained via event chains of purchase from aliens. They cannot be built on planets with the Thrall-World Designation.

Fallen empire

Fallen Empire buildings are found on the homeworlds and planets of Fallen Empires. They are more effective than any building available to other empires, and most of them are autonomous. Buildings that are autonomous can be used by other empires if captured. Fallen Empire buildings ruined by orbital bombardment can be rebuilt.

One of the rewards of the Reverse-Engineer Arcane Technology artifact action is the ability to construct one autonomous Fallen Empire building. Each building takes 480 days to construct.
