Deconstruct or Deconstruction is an action performed by pressing the appropriate button when available.
This action is the final step in the deconstruct process to remove a construction item.
Mechanics[]
Only specific items can be deconstructed. 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.
Once the start deconstruction action is completed, the deconstruct action will appear.
Unlike construction, where you are unable to stop the process of 
building, there is an option to Quit and stop the process of deconstruction. This is your last chance to decide to keep the constructed item or smash it to bits.
Press the appropriate button and the deconstruction process will happen and the item will be removed.
