Oxygen Not Included Buildings Guide — What to Automate

Updated 20 Oct 2026 Source Synthesized from published Oxygennotincluded guides; rewritten in original wording on 20 October 2026 By

The core trio

Oxygen diffuser, a farm and a latrine are the spine of a colony. Everything else builds on a stable base.

Sample buildings: Printing Pod, Plumbing (Building), Decor, Cell of Interest, Stations (Building).

Power comes second

Most machines need power. Plan a conductive wire spine before you switch on a refinery.

Match the problem

Each building solves one issue: heat, water, food, transit. Deploy it where the problem is.

Automate the repeat

If a duplicant does a task daily, there is probably a building for it. Replace labor with automation early.

Read the spec

The building database shows size and effect for each. Check those before you wire it in.

Pair with critters

The critter database lists species that feed your builds. Ranch them to fuel the chain.

Mind the footprint

Every building takes space and heat. Lay them out so they do not crowd the farm next door.

Upgrade in place

Once a loop works, swap in better versions. A small upgrade often beats a whole new wing.

Plan the wire

Run power before you place machines. A building with no power is a dead weight in the base.

Group by system

Place linked buildings near each other. A tight loop wastes less pipe, wire and duplicant time.

Watch machine heat

Machines warm their room. Keep heat-makers off the living and farm zones with insulated walls.

Swap the version

Once a loop works, swap in a better version. A small upgrade beats building a whole new wing.

Frequently asked questions

How many buildings are there?

The wiki lists 24 core buildings spanning oxygen, power, food, refinement and transport.

Where do I start?

Oxygen, food and a toilet come first. Power and refining follow once your duplicants are stable.
