Solved Adding more building items?

Now I cant code and know its probably hard, but is it technically possible for modders to create a plugin that adds more building stuff? For example 90 degree triangles? Or bring back pillars? Or stair cases that go left instead of right?

Would be amazing to have an Advanced Builders mod or something for those of us that love base building. Or add extra items such as toilets or whatever

 

Plugins can't add game assets.

 

Oh thats why everything we see is used making the same assets

Shame really, hope Facepunch will allow real modding at one point
