As long as there's texture in the surface, I think the actual material is less of a concern. My barn, I think, is asphalt... very textured, hard, never seen a horse slip. Kind of hard to sweep really well, though. Posted via Mobile Device
You said dream barn, right? Well, my dreams can be pretty lofty. XD
I used a program called Google Sketchup to make my designs, but here's some labeled screenshots.
The general layout -- an indoor arena (100'x200'), attached to a barn area with twelve stalls.
And here's a close up on the barn area. The stalls are all 14'x14' -- my biggest current horse is a 16' gelding, but I hope to one day own a draft. I also figured that I would go with a larger stall for the rest of the horses, because 1) none of my horses, with the exception of possibly Tanner and Magic, have ever been stalled, so likely would not be used to it, and 2) It's better to have a stall that's too big than too small.
As for the feed/storage area... I'm dead set on having a separate, fireproofed building for hay, it's just a matter of if I want to keep all the feed there or not. I could also probably use the storage space.
The office has a window that opens to the arena, too.
And just an overall view of the entire building. I have the roof of the arena set as being semi-transparent, because I know I want it to be lit by mostly natural lighting, but I'm not sure if I want to go with one of those clearspan-type of buildings, or a lot of skylights, or what. There's also a large door on all three outside walls of the arena, that can be opened to allow airflow and such. (Could probably use it as a run-in, too.)
As for flooring, I'm torn between a textured mat, or textured cement like they have at my mom's workplace.
I warned you that I have lofty dreams.
We do plan on putting a barn up soon, but chances are, it will be a lot simpler than this. And won't have an indoor arena.
This is the pic of almost exact as mine (without that thing on roof though, with 2 stalls 12 X 10 and shed 12 X 16). I have rubber mats in each. Taken from the website of the company (Horizon Structures), which made it and delivered to me. I'd be happy to have an overhang, but it was pricey + you should do it yourself (with parts delivered), so I had to pass... :(
If you do (and they were the cheapest, BTW, I did contacted 3 or 4 companies and looked at everything we had at the Horse Expo) wait till they have a discount. I ordered mine at the Expo and the special was one stall free!
