Quick answer
Get the Square Room when cramped base layout becomes a workflow problem. Follow the databox route, confirm the unlock, return to stable power, then build the room only if it improves storage, crafting, or Biolab planning.

Tactical brief
How to use this guide in a real dive
Square Room Blueprint Guide is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to Square Room Databox Check. Treat that marker as a route anchor: Square Room unlock anchor for base expansion, Biolab space, and organized storage planning. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Databox route (00:12). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. Square Room routes should start with the databox context and a clean return line.

Field manual
Square Room databox manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Square Room is a base workflow unlock. The footage should be read in three parts: reach the databox route, confirm the room unlock, and decide whether expansion actually solves base friction. A big room without power, storage, or a layout plan is just a larger problem.
Primary job
Unlock useful room space
Use the room when hallway bases start slowing crafting, sorting, or research.
Best entry habit
Databox proof
The databox and unlock state are more useful than a vague structure description.
Stop condition
Power not ready
Return after unlock and build only when base power and materials can support expansion.
What to watch in the videos
Watch the route into the databox area before focusing on the unlock screen.
Pause on the Square Room unlock and check whether the blueprint state is complete.
Compare the room value against base storage, crafting, and power needs.
Decision table
The starter base is still underpowered.
Delay Square Room construction even if the blueprint is already unlocked.
Storage is hard to read.
Use the room for labeled storage before adding decorative modules.
The databox route has side objectives.
Unlock the room first, return, then decide whether side objectives deserve a second trip.
Screenshot reading order

Databox route
The route frame makes the databox repeatable instead of a one-time lucky find.
Player action: Record the landmark and return path before interacting with the box.

Room unlock
The unlock frame is the evidence that the page needs to show clearly.
Player action: Check blueprint completion and leave before turning the route into broad looting.

Base expansion
The expansion frame should be judged by workflow, not room size alone.
Player action: Build around storage lanes, power reach, and future scanner or biolab needs.

Loadout and prerequisites
Route timeline
Follow the run in order
Built for second-screen use: complete each checkpoint, then move to the next landmark before detouring for extras.
Decide whether the current base actually needs room space.
Follow the blueprint route and identify the databox area before searching.
Open the databox and confirm the Square Room unlock state.
Return before side scanning turns the trip into a broad sweep.
Build the room only after power, storage, and material counts are ready.
Guide notes
Room space should solve friction
Square Room is useful when it makes storage, crafting, or research easier. If it only makes the base larger, it can wait behind power and scanner workflow.
Databox evidence
The route note should include the room, databox, unlock screen, and return path. That is enough for a player to repeat the route without needing every coordinate.
Risk controls
Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.
Chasing Square Room before the starter base has power and storage.
Opening the databox but not checking whether the unlock completed.
Building a large room that makes the base harder to navigate.

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.

Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
