Short wall

"'A passable chest-height wall. Cannot support roofs.'"The short wall is a Structure available in the Vanilla Furniture Expanded - Security module. It is passable by pawns and animals similar to barricades and sandbags.

There is no required Construction level required to build this structure.

The short wall is not capable of supporting a roof.

If the Royalty expansion is enabled, this structure provides 22% meditation psyfocus bonus to pawns with the Ascetic trait.

Strategy
The short wall provides the same cover as a barricade (57%), requires 20% less resources, and has 20% less HP. It also does not incur a Beauty penalty and may give a Beauty bonus depending on the material type. Thus, it can be used in place of barricades or sandbags to lessen the risk of mental breaks by pawns standing on a firing line due to experiencing ugly environment thoughts. However, the decreased durability is probably not worth it.

Since the short wall is passable by pawns but slows movement, it may be useful to manipulate pawn path-finding. For example, short-walling a crop field or dumping stockpile can be used to encourage pawns to path around filth-generating terrain or objects with negative beauty.
