12×24 Pole Barn Plans – Free PDF Download

This step by step diy woodworking project is about free 12×24 pole barn plans. I had a request for a medium sized  pole barn built on a post frame structure, so this is my take. The posts will be set to the footings using anchors, so the lumber is protected from the elements. You can cover the pole barn with OSB and siding, or you can go for metal sheets. Read the local building codes, so you make sure you comply with the building codes. In addition, attach a roof to protect the construction from bad weather. Make sure you take a look over the rest of plans to see alternatives and more projects for your garden.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

How to build a 12×24 pole barn



The first step of the project is to build the posts for the barn shed. We will be setting the posts with anchors, so this is the size of the posts you need for the project. If you want to set the posts into the ground, add 3-4′ to the posts length.



Use the color code from the diagram to place the posts properly. Use batter boards and string to lay out the posts in a professional manner. Apply the 3-4-5 rule to the corners to make sure they are square. In addition, make sure the diagonals are equal. It is essential to take accurate measurements before fitting the posts.

Remove the vegetation layer and make sure the surface is level.

Installing the posts

Installing the posts

After marking the location of the posts, dig the holes and then set the anchors into place. Align all the anchors one with another for a professional result. Let the concrete to dry out and then install the 6×6 posts. Use a spirit level to plumb the posts.  In addition, use temporary braces to lock the posts into place tightly while pouring the concrete in the holes. Make sure the top of the side posts are horizontal and cut out any excess.

Framing the door opening

Continue the project by framing the front door opening. You can adjust the size of the opening to suit your needs, but I show you the framing techniques. Fit the 2×6 cripple studs and the top 6×6 header. Use 5 1/2″ screws to lock the components into place.

Front and back splash boards

Next, fit the 2×6 (you can use 2x8s as well) for the splash boards. Align the edges with attention and use a spirit level to make sure they are perfectly horizontal. Drill pilot holes and insert 3 1/2″ screws to lock them into place tightly. Invest in pressure treated lumber, as these boards will be exposed to moisture.

Fit the 2×6 splash boards to the sides of the pole barn. Align the edges flush and insert 3 1/2″ screws to lock them to the posts. Drill pilot holes before inserting the screws to prevent the wood from splitting.


Building the frame of the pole barn

Continue the project by fitting the band beams to the front and back of the pole barn. As you can notice in the plans, you need to clamp the beams to the top of the posts and lock them into place with 3 1/2″ lag screws. Use 2×8 lumber for the beams (the local codes will determine the size of the beam more accurately).

Next, fit the truss carriers to the sides of the small pole barn. Align the edges, make sure the beams are horizontal and then lock them to the posts with 3 1/2″ lag screws.

Front wall girts

Next, you should start attaching the girts to the front of the pole barn. Lay the 2x4s to the posts, as shown in the plans. Align the edges and insert 3 1/2″ screws to lock the girts to the posts.



Fit the 2×4 horizontal girts to the sides of the pole barn. Place the 2×4 girts every 2′ on center and secure them to the posts with 3 1/2″ screws.

Back wall girts

Back wall girts

Fit the 2×4 supports to the back of the barn, as shown in the diagram. Place the supports equally-spaced and lock them to the the poles using 3 1/2″ screws.
