Barn costs by construction type & use

Hay barn $15 – $40 per square foot
Cattle barn $600 – $1,600 per cow

Small barn shed or shop cost

A barn shed costs $20 to $100 per square foot for a small building used for storage or a workshop. Metal sheds are more popular since they resist mold, pest, and fire damage, and require less maintenance than wood buildings.

Cattle barn cost

A cattle barn costs about $600 to $1,600 per head to allow at least 20 square feet of space per cow. A free-stall barn requires more space to let cows to move around freely.

Horse barn cost

The cost to build a horse barn averages $7,000 to $11,000 per stall. Each stall should allow about 100 to 150 square feet of space per horse. A run-in barn that allows horses to move around freely requires more space.

Hay barn cost

A hay barn can cost as little as $15 to $40 per square foot for a simple pole barn. The hay barn size is determined by the number and type of bales you need to store, with round bales needing more space than square bales.

Hog barn cost

A hog barn costs $50 to $300 per pig for a finished space. The shelter should have at least 8 square feet of space for each growing pig, allowing them to turn around without touching the sides of the enclosure. A well-ventilated, dry shelter with a floor will keep pigs healthier.

Barn house cost

Barn houses cost $50 to $160 per square foot of finished space, not including the land. Most often built in rural areas, these affordable homes have large open floor plans, exposed beams, and a gambrel roof.

  • A pole barn house costs $50 to $150 per square foot for a finished post-frame construction with wooden or metal posts driven into the ground.

  • A barndominium costs $65 to $160 per square foot for a finished home designed to look like a barn.
