I live on a farm and I hate winter. I live alone and it gets real lonely during the winter. I decided that I want to bring my horse in the house this winter, for companionship. He's an average 1000lb horse. My floor is made of 2x6's spaced 24" apart, and covered with
3/4" boards with 1/2" plywood on top. I plan to cover the floor with another layer of 3/4" treated plywood in the horse's room, and then apply rubber mats, using silicone caulk in the seams of the mats to prevent liquid from getting to the wood. I also plan to cover the bottom of the walls with 1/2" treated plywood. (He is not a kicker, but sheet rock is too easy to break). My question is whether the structure is strong enough? I am thinking I should put another 2x6 between each of those existing. I am also wondering if I should add some extra posts and beams. What do you think I need?If the floor is too weak, I was thinking that I might be better adding an extra room on the house with a poured slab, and just heat that room along with the rest of the house. It would cost more to add an addition, but this is also possible. This way I could cut a door from an existing room to the addition, and I could add a space to store hay too, so I would not have to run outside to get it.
