These are the four GT wood walls (five material variants each) made available as floor tiles. I think they secretly wanted to be floors anyway.
I put the “Matchstick” and “Horizontal Planks” in the same thumbnail since they are very similar, the other two are separate. Same material variants as the walls, 4§ each, in Floors > Wood.
No textures included here, everything is referenced directly. So this is only useful if you have GT installed.
