How do I add a new floor in Gnomoria?

Question

I'm trying to add a new floor in Gnomoria. I removed a clay for (before realizing that there was a replace command). Looking at the wiki under Construction Strategies I saw that there is supposed to be a way to add new floors (Terrain_Floors). However, I don't see this under my list of terrain build options.

Is the wiki correct, and am I just missing something? Also, is there any way to just add a new floor?

Thanks!

Finally found it! What threw me off is that the floor is not in the terrain menu. Instead you can add a floor by starting at the base menu as follows:

Build -> Terrain -> Floor
