This mod includes two machines, one for making concrete and another for turning concrete into decorative walls nodes. There are three styles of walls along with some decorative column toppers and patio blocks.
Mylandscaping
Lets you put up decorative walls around your gardens, and make pretty hardscapes.
A hilarious mod
Decoration mods aren't my thing usually, but this mod has some really high quality assets. I like the machinery and the floors. You could make a sick garden with this.
