====Planning====
You must right-click on a finished [[Floor]] or staircase with a [[hammer]], or [[mallet]], or [[trowel]] and select ''Plan > Build clockwise/counter clockwise spiral staircase with banisters''.
*Be careful when creating one against a wall, as planning a wall on the floor above will be more difficult.
*You can plan on top of other stairs. Note: building spirals in opposite directions on top of each other will not be accessible.
