The Alterra handheld Habitat Builder is a tool crafted using the Fabricator


The Habitat Builder allows the player to build a variety of stationary items. It is a crucial tool for the deployment of Seabases and the customization of the interiors of both Seabases and the Cyclops.

The Habitat Builder requires a Battery to operate, and objects cannot be constructed/deconstructed if the battery is depleted. It has a gauge on the back that tells the player how much battery charge it has left.

If a Bleeder latches onto the player's arm, the player can use the Habitat Builder to hit the Bleeder.

How to Use

  1. RMB (Xbox One:XBOX Right Trigger, PlayStation 4:PS4 R2) to open the Habitat Builder menu
  2. Select the desired tab: Base Pieces, Exterior Modules, Interior Pieces, Interior Modules or Miscellaneous
  3. Select an item
  4. Point the Habitat Builder at wherever the item should be placed until an outline appears
  5. Use Up and Down Mousewheel (Xbox One and PlayStation 4:PS4 Dpad LeftPS4 Dpad Right) to rotate object, if applicable.
  6. Press LMB (Xbox One:XBOX A, PlayStation 4:Combops4x) to place the outline
  7. Continue building the item by holding LMB (Xbox One:XBOX A, PlayStation 4:Combops4x).
  8. Done.
  9. Placed items can also be deconstructed by pointing the Habitat Builder at them and holding Q (Xbox One and PlayStation 4:PS4 Dpad Down), this only applies if the text "Hold to Deconstruct" appears on the screen. This also gives back all resources used in the building process.

The Habitat Builder cannot build onto a corridor section that has any wall-mounted objects at the end the new part is being attached to (for example, lockers on the walls). In addition, if there is something directly where a new module will be joined, such as a Water Filtration Machine or Hatch, it should be manually deconstructed first: if it is not, it will be deleted and the materials will not be refunded to the player.

Bulkheads can only be built in placed corridor sections, not in the auto-generated corridor sections created by some rooms, such as the Moonpool and the Observatory.

Data Bank Entry


The Alterra handheld habitat builder has been an essential tool of xenoscientists, colonists and emergency relief crews across 11 different trans-govs for more than 50 years.

- Habitat modules are hermetically sealed from the outside environment
- Build on land, underwater, or in a vacuum
- Habitats can be enhanced to become long-term homes, remote research stations, defensive outposts and more

Quick Start Guide:
1. Select the basic compartment from the builder menu and place it somewhere opportune
2. Add a hatch to access the compartment
3. Build a solar panel to power the habitat's oxygen generator
4. Construct useful interior modules like radios, rechargers and storage solutions

Primary habitat systems like oxygen generation and flood control, as well as modules like the fabricator draw power and will not function without it. Additional compartments reduce overall hull integrity, depending on the external pressure.

'Quick-Build Habitats: A home far, far away from home.'



  • The idea for the Habitat Builder may be taken from Natural Selection 2, where the Builder is used to create various machinery, much like Subnautica's.
    • And thus, the Habitat Builder's former name was the Builder.
      • However, the fabrication message was not changed
  • The Habitat Builder originally could construct many base segments that are now cut, including the Fragment Analyzer, the Specimen Analyzer, the Botanical Analysis Machine, and the Power Generator.
    • All have been removed in the final game, and can only be spawned in using Console Commands.
  • The power left in the Habitat Builder's battery can be seen as represented with a blue power meter.


This section contains bugs related to Habitat Builder. Make sure to only post reproducible bugs, and use appropriate system template ( XboxLogo, PlaystationLogo, WindowsLogo / AppleLogo ) depending on which platform(s) the bug has been encountered on.

  • WindowsLogo Both the T Compartment and the X Compartment, when constructing, require three titanium. However, when deconstructing, they only yield two titanium in return. This is a carryover from when the two pieces originally cost two titanium each, which was switched to three when habitat module recipes were being redone.
