This step by step woodworking project is about free 16×20 pole barn plans. If you want to build a basic pole barn, I have created free plans for a 16×20 shelter. This pole barn is easy to build and features double doors on the front. My plans come with step by step instructions and you can easily adjust all the dimensions to suit your needs. See my other DIY projects HERE.
We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting.

Building a 16×20 pole barn
The first step of the project is to cut the 4×4 posts for the pole barn. Make sure you check out the local building codes, so you see the proper depth you have to set the posts in concrete. In most cases 3′ will be enough for the footings.
In order to lay out the posts, you need to use string and batter boards. Apply the 3-4-5 rule to each corner so you make sure they are right-angled. Moreover, you need to measure the diagonals and make adjustments until they are perfectly equal.
Dig 3′ into the ground, about 10-12″ in diameter and then fit the pressure treated posts into place. Use a spirit level to plumb the posts and make sure they are perfectly aligned. Use temporarily braces for the posts until the concrete dries out.
Attach a 2×10 beam to the base of the walls, so you seal the pole barn properly. Next, attach 2x4s to the posts, so you have proper supports for the siding sheets. Align the edges with attention, drill pilot holes and insert 3 1/2″ screws to lock them into place tightly.
Attach the supports to the front of the pole barn, as well. Drill pilot holes, insert 3 1/2″ screws and create even gaps between the supports for a neat result.
Fit the supports to the sides of the pole barn, making sure you place them equally-spaced.
The next step of the woodworking project is to attach the T1-11 siding sheets to the sides of the pole barn. Align the edges flush, leave no gaps between the sheets and lock them into place with 6-8d nails. Insert the nails every 8″ along the framing.
Attach the siding sheets to the front wall of the pole barn, as well. Align the edges flush and use 6-8d nails to lock them into place.
Last but not least, attach the siding sheets to the sides of the pole barn, as well.
