This is anwered in the manual, actually:
Conflicts
Actions can conflict with each other. For example, the Meier family tries to take a piece of land from its neighbours, the Schulz. However, Juergen Schulz is planting a field in that same spot in the same turn. What will happen?
The rule for resolving conflicts is: - Taking or clearing land and harvesting only succeed if no other action targets the same plot.
- Planting only succeeds if no other action, except maybe another plant action, targets the same plot.
- Building succeeds if no other action, or an identical build action, or a planting action targets the same plot.
For resource conflicts, it is important to know that forest actions (gathering wood, stone or food) are resolved before village actions (building, repair, etc.). Actions within the village are resolved in random order.
For eating, the most hungry family members will eat first (within those who have the same hunger level, the order is random).
Monsters are resolved last, after all actions by villagers, obviously (first day, then night).
Unfortunately it isn't - I had already checked
To clarify my question further (and some people may not have realised this and will find it useful): a person can claim the wood and stone stored in a hut that is built on common ground by building something that uses more wood or stone than they themselves currently have. If the only wood stored in a common hut in 1 village amounts to 6 lumber, and two people who have no wood and are gathering no wood try to build a henhouse, who will get the wood?
