A habitat in Stellaris is a megastructure in the game built when your species wants to thrive on a surface outside of a traditional planet. There are three types of habitats, and they each require quite a bit of resources for you to construct them. You build them overlooking planets, and they have a 70% base habitability rating for all species, so it should work for any species in the galaxy. You can have a habitat megastructure built in your Stellaris game if you have the Utopia or Federations DLC enabled in your game.
Before building the habitat megastructure, you need to have completed researching them in your research tree. They stem from the engineering tech tree, so if you want to rush them, we recommend increasing your engineering base research.
Once you have them, you can build a habitat overlooking any planet in any sector of the galaxy. It’s important to note that the districts you can build on your habitat reflect the planet below the habitat. For example, when you build a habitat overlooking a planet with energy credits, you can construct a generator on that habitat. It wouldn’t be able to do that for minerals unless it’s overlooking a mineral-based planet.
These are the construction costs of the three habitats in Stellaris.
|Required Technology||Resource Cost||Time||Population Size|
|Orbital Habitats||150 Influence|
|Habitat Expansion||1,000 Alloys||720 days||6|
|Advanced Space Habitation||1,500 Alloys||1,440 days||8|
Habitats can become extremely important later in the game when you find that expansion is becoming problematic. Rather than conquest another empire or stretching yourself too thin for you citizens to find new locations to live, you can construct a habitat. While they are costly, they’re worthwhile if you want to avoid conflict with another empire and still expand your domain.
Some players also use habitats as a way to slow down the conquest of another empire slowly grabbing more of their territory.
