Alright I got annoyed with the built in game walls, they're terrible to place and make a proper campsite/village so I decided to use the in game mod maker a try and also some simple textures with photoshop.
Building MOD
Prototype Walls - Vertical and Horizontal
One was intended to be used as a functional wall, while the other to be used for a pool.
Still need some testing,
Tips:
Interactable area is at the top. Hold 
CTRL and click it for easy editing/moving an already placed wall..
Features:
- Walkable area on top - Needs further testing
 
Known Issues:
- Clipping with Tall creatures/Humans
 
Planned:
- Material Requirements
 
- HP
 
- Proper Icons when Mouse Over
 
- Diagonal version (Similar to vanilla)
 
- Wooden Textures/Version
 
- Snapping
 
Install:
Craftable from Workshop bench
PS:  Indestructible, so don't exploit it to much.
