These free barn plans will give you free blueprints and layouts so you can build your very own barn. These barns range from the simple and the small to the large and complex so there should be a plan here for your skill set and needs.

You'll find free barn plans for both one- and two-story barns here in a variety of sizes from 16x30 all the way up to 40x44. Some of the plans also include guidance on how to add lean-to's, cow stalls, feeding rooms, calf pens, and horse stalls to your barn plan.

Want to get the feel of the barn without the actual barn? Here are some free plans to build barn doors for your home.

A bit different than the other barn plans on this list is this one from Ron Fritz of The Creekside Woodshop. To see this barn from any angle, and to measure every single component of it, requires the free SketchUp program. Once loaded into SketchUp, you can even make large or minute changes to it and see the effects in real-time. Once downloaded and opened in SketchUp, the barn is 24x26 by default.
