Pillars are vertical supports for buildings on players’ plots which can be purchased in Build Mode. Added in Version 0.8.5, players can place most wall objects onto pillars. Players are not required to add pillars to their builds, and are simply made for aesthetics and to improve design in some ways.
Placing a Pillar on all corners and ends of a wall can make the wall more detailed. This may require the advanced placement gamepass.
You can substitute a wall for a pillar if you want to by placing pillars next to each other in a line, this may require the advanced placement gamepass.
Certain pillars give a aesthetic look to your house, when placed in the front or sides of a house.
