A useful base shortens the time between returning from one expedition and leaving for the next.
Organize storage by activity
Building, food, ores and equipment should each have predictable places.
Keep high-use crafting areas compact
Repairs and upgrades should not require unnecessary movement through the base.
Make food preparation visible
Keep ingredients and finished food easy to review before difficult trips.
Maintain spare essentials
A small reserve of tools, food and basic gear turns a death into a short recovery instead of a full rebuild.
