Best Base Building Tips for Subnautica 2

Build your first base early in Subnautica 2, ideally near the Lifepod or another useful landmark, so you can craft, respawn, and avoid constant backtracking.

Use beacons to mark key locations and consider multiple small bases instead of one huge headquarters, especially as you explore farther from your starting area.

Expand rooms efficiently with the habitat fabricator, and place core tools like the fabricator where they are easy to reach.

Match your power source to the environment: solar for shallow water, bioreactors or hydroelectric options where useful, and thermal plants or transmitters for deeper areas.
