Build or Building is an action performed by pressing the appropriate button when available.
This action is the third and final step in the construction process to transform a stockpile of items into another potentially more useful item.
Only items that can be constructed into another item will show this action.
Mechanics[ | ]
Once enough items are available on a stockpile by using the 
Add To Pile action, stand over the stockpile and 
Start Construction will appear as an option.
Once the start construction action is completed, the build action will appear. Successfully performing the build action several times will complete the construction of the item.
Construction items[ | ]
There are only a few constructed items that have specific uses:
- Four
Dead Branches can be used to construct a Branch Barrier. - Four Natal Grass Cycads can be used to construct a Sleep Spot.
- Four Thornbushes can be used to construct a Thornbush Wall.
The construction stockpile requirement can be reduced by learning the Building (NE 01) and Building Efficiency (NE 02) neurons.
Deconstruction[ | ]
The Branch Barrier and the Thornbush Wall can be removed after construction by using the Start Deconstruction and Deconstruct actions. If you use these actions, the materials used to make the construction will be lost.
