LOVE your barn, it's adorable!!!
Mine is VERY boring. Here in Az, it's best to have very open areas with just a roof, the more ventilation the better due to our heat. So most people, such as me, jsut have what are called mare motel type barns: corral panel type fencing with a roof. I have some stalls like this and then pens with a roof in part. Not much to look at, but the most functional here in the heat!
