Unique buildings

Holdings

Unique buildings are buildings that can only be built a limited number of times. These limits fall within two main categories:

• Planet-limited buildings are buildings that only a set number of can be built on a planet. Their planet limit is usually set to 1, meaning only one building of that type can be built per planet.
• Empire-limited buildings are buildings that only a set number of can be built in the empire. Their empire limit is usually set to 1, meaning only one building of that type can be built in the empire.

Many of these buildings require the capital to have reached a certain level.

Planet-limited

Unless stated otherwise, these buildings can only be constructed once per planet.

Monuments

Monument buildings increase unity output from jobs and produce it themselves based on the number of taken ascension perks. Monuments cannot be built on  Thrall-World Thrall-Worlds. All monuments convert to the appropriate type if the colony is transferred or conquered by another empire. Each monument tier requires a capital building of at least that tier or above.

Tier	Non-Gestalt Culture Workers		Hive Mind Evaluators		Machine Intelligence Evaluators		Memorialist Death Chroniclers		Jobs	Unity	Cost	Requirements
I		Autochthon Monument Corporate Culture Site		Sensorium Site		Simulation Site		Sanctuary of Repose Upkeep: −2	+2	+1 per perk +5% from jobs	360 400

III		Hypercomms Forum Synergy Forum		Sensorium Complex		Simulation Complex		Galactic Memorial Additional cost: 100 Upkeep: −8 −2	+6	+3 per perk +15% from jobs	600 800	Local Hypercommunication Confluence of Thought

Memorialist monuments have an additional effect on Tomb and Relic worlds:

• Individualistic Memorialists gain +20% governing ethics attraction.
• Gestalt Memorialists gain −20 deviancy reduction.

Job output buildings

Job output buildings increase the output of certain jobs. None of these buildings can be built on  Resort World Resort Worlds or Gestation Worlds. Tiered buildings require that tier of capital or higher.

Basic resource buildings

These buildings increase the base output of basic resource jobs. Tier II buildings get additional effects, cost, and upkeep on Ring Worlds, including Shattered Rings.

Some of these buildings give machine species more resource districts of their corresponding resource on natural worlds (i.e. not Ring World, Hive World, Machine World, Ecumenopolis, or Habitat).

Industrial buildings

These buildings increase the base output and upkeep of industrial jobs. Tier III buildings get additional effects, cost, and upkeep on Ring Worlds, including Shattered Rings. They cannot be built on  Thrall-World Thrall-Worlds.

Pop assembly buildings

Pop assembly buildings provide assembly points – directly or through jobs – towards either organic or mechanical pop assembly. Only one of the two types of pop assembly can be active at a time; if the planet is currently assembling a mechanic pop, organic pop assembly has no effect.

Additionally, some pop assembly buildings increase the amount of pops with auto-modding traits adjusted each month.

Planetary feature buildings

These buildings are limited based on the number of certain planetary features. Except for the Alien Zoo, they cannot be built on Resort Worlds or Gestation Worlds. The Alien Zoo can also be constructed on planets with pre-sapient pops if their policy is set to Protected or on planets with livestock slavery pops.

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. Phase 1 requires a Tier II capital or above. Upgrading it to Phase 2 and above requires the following planet classes:

• With no terraforming technology, the planet class must match that of the primary species' homeworld. Upkeep on such worlds is not increased.
• With Terrestrial Sculpting technology, the planet needs to match the climate of the primary species' homeworld. Upkeep on such worlds is increased by +25%.
• With Ecological Adaptation technology, the planet can be of any class except Tomb World. Upkeep on such worlds is increased by +50%.
• With Climate Restoration technology, 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 into a Gaia world ( Ecumenopolis, Hive, Machine, Relic, and artificial worlds). If the world is terraformed into such a class, the building is removed. The Final Phase building remains on Gaia worlds, and boost Bloomed and Budding traits.
• On Gaia worlds without a Gaia Seeder building, the Final Phase building can be built without the need to go through earlier phases.

Synaptic Lathe buildings

Unique buildings that can only be built on the Synaptic Lathe. They have the planet limit of 2, meaning only two buildings of the same type can be built on the Synaptic Lathe. With the max building slots of 6, only six building can be built in total.

Cybernetic Creed buildings

The following buildings are available to empires with the Cybernetic Creed origin. The first level buildings convert to a Temple on conquest by another empire. They cannot be built on  Thrall-World Thrall-Worlds or  Resort World Resort Worlds. The capital starts with one of each of the first tier creed buildings; more creed buildings can be built after embracing a creed or unifying the faith in The Conclave of Fusion situation. These buildings cannot be manually destroyed.
