Mine would be a raised center aisle barn. I'm not sure how many stalls it would have because I don't actually own any horses at this point. It would have rubber brick flooring with a nice wide aisle. There would be a big tack room and one or two grooming areas across from the tack room. I would probably go for stall fronts with a grill and the yolk style so the horses could look out. Blanket racks and a hook for halters would be on each stall, along with a name plate! Not sure about hay storage. Outside there would be a paved area with a hitching post. Of course this is just a teenaged girl's probably impractical idea, but I can dream!
What is your dream barn? Feel free to post pictures. If you already own your dream barn, post pictures of it.
