Buildings can be built on cleared tiles on colonized planets. All buildings can be demolished, replaced (the original building will remain operational until the process is completed) or deactivated to stop the maintenance cost.

Contents

Yield suppression

Tile yields provided by buildings will stack additively with tile yields provided by the tile itself only if they're of the same type. Other yields will be suppressed. For example, if a farm is built on a tile that gives energy, the energy output will be lost. If a power plant was built instead, the energy would stack additively with the output from the power plant.

Adjacency

The colony capital and some tile blockers have adjacency effects, meaning that they provide a bonus to any tile with a building directly bordering them (not counting diagonals). As with yield suppression, this only has an effect if the adjacent building outputs the given resource.

Colony Capital

All capitals provide Energy and increase Governing Ethics Attraction. All but the most basic capital also produce Unity and provide an adjacency bonus to Food, Minerals and Energy. An upgraded capital is also a prerequisite for most higher level buildings. All colony capitals produce an additional +1 Unity with the Colonization Fever tradition.

Energy

Energy buildings include both power plants and power hubs, both produce energy credits, the latter giving a bonus percentage to the total planetary energy output.

Mineral production

Mineral buildings are used to produce minerals for the empire. They include mineral silos, mining networks and mineral processing plants. The first increases the storage capacity of minerals, the second extracts crucial minerals from the planet's crust and the last gives a bonus percentage to the total planetary mineral output.

Mineral silos

Mineral silos increase maximum storage capacity for minerals and provide minerals for neighboring buildings. Mineral Silos are planet unique, meaning that only one can be built per planet.

Unity

Unity buildings produce Unity for the empire. With the exception of the Auto-Curating Vault, which is empire-unique, they are planet-unique.

Unique

Unique buildings are limited in how many times they can be build and often provide special benefits. Planetary uniques can be built once on every planet. Empire uniques, which grant empire-wide bonuses, are limited to one in the empire. Buildings limited by government type can be built once per ruler, but are not limited in how many times they can be built in the empire or on a single planet.

Habitat

Habitats have their own set of buildings that are available only on habitats. The only exceptions are certain planet unique buildings and buildings associated with the Horizon Signal event chains. The buildings do not need to be unlocked, but constructing Habitats requires the Voidborne ascension perk.

Primitive

Primitive buildings are found on planets inhabited by pre-FTL civilizations. They cost no maintenance but are less effective than regular buildings of the same type available to normal empires. After a planetary administration is constructed they can be upgraded to their futuristic counterparts.
