A horse barn will cost from around $10,800 for a 2-stall barn up to as much as $48,000 for a 14-stall barn. Costs of material and labor vary by location and are cheaper if you can get by without hiring a general contractor.
There are a couple ways to build a barn which vary significantly in cost. Pre-fabricated steel barns are one way. They can be constructed in just a few days and cost between $7 to $25 per square foot. The second way is building a traditional wood barn. This takes weeks to construct and costs in the neighborhood of $45 per square foot. Another factor that affects the cost is the style of barn. Barns with a Quonset-style construction are cheaper than barns with straight walls and a pitched roof.
