Hut not enterable. (Is this a bug? Or just not implemented?)

Found a small hut with a door.  (Size of a small tent)  Had a tower and machinery attached to it with 3 oxygen bottles attached.  Thought it was an emergency shelter (someplace you can stop to eat, drink, sleep) but the door had no interaction.  The only items that could be interacted with were the supply crates nearby and the oxygen bottles (which you could loot).

If it isn't supposed to be entered, there needs to be a visual reason not to.
