Quick answer
Current blueprint data lists Habitat Builder as locked behind scanning 2 Habitat Builders. After the blueprint unlocks, craft it at the Fabrication Station with Titanium x2, Glass x1, Basic Battery x1, and Copper Wire x1. Treat Copper Wire and battery prep as the easy-to-miss parts, then mark the first base with a Beacon before the layout grows.
Field notes before building
Scan first, shop later
It is easy to overfarm before the recipe is actually unlocked. Finish the scan requirement first, then let the PDA tell you what is still missing.
Copper Wire is the quiet blocker
Players usually remember Titanium. The thing that stalls the craft is often the Copper already spent on batteries. Save the wire before making spares.
Build the ugly working base
A hatch, power, locker wall, and clear return route matter more than a perfect first room. Make the base useful, then make it pretty.
Habitat Builder unlock plan
Bring the Scanner first
The tool is not a default craft. Current databases say you need 2 Habitat Builder scans, so the first job is a focused scan run, not a material hoard.
Prepare the recipe at base
Once the scan unlock lands, check Titanium x2, Glass x1, Basic Battery x1, and Copper Wire x1 before opening the Fabrication Station.
Do the Copper split early
Basic Battery and Copper Wire both pull from Copper. Make the battery, reserve the wire, and avoid spending every Copper piece on spare tool power.
Craft the tool before decorating
Habitat Builder unlocks the base-building loop, but the first goal is function: hatch, power, storage, and a route hub you can actually find again.
Place a beacon before you expand
A starter base only helps if you can return to it quickly. Drop a Beacon, name it by the resource route it supports, then start adding power, lockers, and later a Scanner Station.
Build a working starter base
A small powered room with storage beats a huge shell with no rhythm. Expand after the base shortens Copper, Silver, Scanner, and food runs.

Habitat Builder checklist
| Requirement | What to confirm |
|---|---|
| Scanner | Needed for the 2 Habitat Builder scans in current data. |
| Titanium x2 | Common, but easy to spend on base pieces too early. |
| Glass x1 | Prepare the glass side before the craft check. |
| Basic Battery x1 | Do not forget the battery while splitting Copper for wire. |
| Copper Wire x1 | The electronics piece that links this tool back to Copper planning. |
| Beacon marker | Mark the starter base before you leave to gather more parts. |
Do not turn the first base into a showroom
The Habitat Builder can tempt you into a huge layout before the base has a job. Start with the pieces that save time: a reachable location, power, storage, and a clear route back out.
FAQ
How do you unlock Habitat Builder in Subnautica 2?
Current blueprint data says to scan 2 Habitat Builders with the Scanner. After that, the tool becomes craftable at the Fabrication Station.
What is the Habitat Builder recipe?
Current data lists Titanium x2, Glass x1, Basic Battery x1, and Copper Wire x1.
What should I build first with Habitat Builder?
Start with a simple working base: room, hatch, power, storage, and crafting access. Pretty layouts can wait until the route is stable.
Why am I missing Copper Wire for Habitat Builder?
Copper Wire competes with batteries for early Copper. If the tool is blocked, check whether you spent every Copper piece on spare batteries first.
