Our barn, unfortunately, has none of these. It's a relatively new structure, about 15 years old, but was built by people who were interested in picturesque. They knew very little about barn construction or barn operations and many of the decisions they made were poor. As a result, our barn is poorly ventilated, requires endless and expensive maintenance, and don't get me started on the fencing and the outdoor, both of which are very deficient. The biggest problem we have is that we can barely afford the annual costs of labor and maintenance and never have any money left over to improve anything. The one advantage is that I don't own it so can walk away at any time if I choose.
The big advantage for me is that it is very close to my house (a couple of hundred yards), and that we have all-day turnout, with excellent (almost too good) pastures in the summer months. I also get a big say in how my horses are handled and fed - not having this is to my mind one of the biggest deficiency of many boarding facilities.
I often dream of my ideal barn - it wouldn't be too fancy. It would have all the necessary features for horses, and would be sited on the property so that turnout was easy. Everything would be constructed to be low maintenance and safe. It would have an indoor so I could work my horses in the winter and when the weather was bad. The horses would mostly live outside, with big loafing sheds and round bales under cover in the winter.
I'm certainly not saying that it's not possible to live with a less-than-perfect barn and facility. Many people do so, and happily work with and enjoy their horses. I'm just considering an ideal world here.
Now, why haven't I found my own place and done this? I don't really know - probably worried I couldn't manage all the work on my own and worried about the expense. If you have your horses at your own place, how did you decide to do it, and how did you go about it? If you would like, put a post on your own blog (link back to this if you like) and leave a comment here letting us know that you have done so. I'd really be interested in how people have decided to have their own places rather than continuing to board.
