Hello again all.
So I have been planning out my barn project. I'll probably use the Canada Plans gambrel roof barn. I believe I can have the gambrel trusses built at a truss place, which should save time.

But this question is about floors: This is going to be a small, multiuse barn. A proper foundation (below the frostline) or a slab will cost me about the same. If I make a slab, I get the floor 'for free' if I pour a 4" concrete floor (for the foundation) it will cost me an additional 50%.

So for so good. But I read somewhat that a horse barn should have clay floors, elsewhere I read paving stones, somewhere else rough (brushed?) concrete.

What say yee? I don't have any horses, but I think the barn should be designed just in case ....
