Planetary Colony Tiles

[altasilvapuer]

Egresses
Aerial:
Perhaps some sort of bay for a small aerial craft, for colonies in areas where travel by air might actually be more practical and/or efficient, like high mountains, a planet with low gravity, or distant (secluded) outposts on planets with larger colonies elsewhere.

Misc.:
Airlocks

Colony Tiles
-Storage rooms (mining equipment, pressure suits, etc)
-Hydroponics (as mentioned before)
-Command & Control Room (essentially 'The Bridge')
-Brig
-Decontamination rooms

And of course if you're going for Planetary Colony tiles, you have hostile environments, so airlock stylie egresses. Subterrainain <sp?> would also be a possibility.
