Instructions
Examine the type of barn you have to work with, since the existing structure will influence the optimal layout of the barn. If you have a barn with a loft, for instance, you can use that loft to store hay and pull it down as you need it. If you have a pole barn with no loft, you will need to set aside part of the structure to store hay.
Create an elevated platform for storing hay within the barn if you do not have a loft available. You can use wood pallets to raise the hay up off the floor and prevent the moisture in the ground from getting into the hay and creating mold. Eating moldy hay can make a horse very sick, so you need to use caution when creating your hay storage area.
Set up a separate tack room or simply hang your saddles and bridles in the same area where you store your feed and hay. If you have plenty of space to work with, you might want to keep your hay storage and tack room separate. If you are pressed for space, a combined area works just as well. If you do decide to combine your hay and tack storage, you could conceivably free up enough space for another stall.
Measure the area you have available for stalls, keeping in mind that the minimum stall size for a full size horse is 10-by-10 feet. A 12-by-12-foot stall is even better. The floor of the stall should be packed earth and not concrete. If you are converting an old dairy barn or similar structure, you will need to remove the concrete or at least install thick rubber mats to protect your horse's joints and legs.
Place a door between the stall area and the tack room or combined tack and hay storage area. Use a secure latch that is easy for you to open and close but impossible for your horse to work loose. You can get recommendations for proper latches at your local feed store or tack shop.
How to Set Up a Horse Barn
Whether you have one horse or several, you need to design your barn with both your comfort and the comfort of your animals in mind. A properly designed barn will make it easier to care for your horse, and easier to store the feed, hay and tack you need to care for your animal properly.
