Digging deeper you’ll discover whether the type of building you want is indeed a pole barn, also known as a post-frame building.

Thus, to help you out, in this article, you’ll have a chance to learn more about pole barns, the uses of 20 x 40 Pole Barn, and how much it takes to build one.

What Is a Pole Barn?

A pole barn is a type of structure that uses poles as its mainframe. The poles are set in the ground and serve as support for the roof and walls. This type of construction is popular because it’s easy to build and doesn’t require a lot of materials. Pole barns can be used for a variety of purposes, such as storage, workshops, and even homes.

A pole barn has six components which include the following:

  • Footing type
  • Columns/Posts (Laminated woods)
  • Girts
  • Trusses
  • Purlins
  • Steel

Originally, footings were made by digging a hole in the ground but nowadays there are a variety of options you can choose from but using a concrete footing with a wet set bracket is a pretty strong and reliable one. During the 1930s, the posts or columns were made up of telephone poles. At present, laminated woods are being used.

What Are the Advantages of a Post-Frame Building?

Using post-frame building is a growing trend nowadays. Below I listed some of the reasons why people choose pole barns over other types of buildings:

  • Large Space – Owners can drive their cars inside without worrying about hitting posts or beams.
  • Easy to Build – So, if you’re a person who loves to do everything yourself, erecting your building is feasible. Thus, you’ll also save costs due to lesser labor costs. If you want to change some features of your building in the future, you can also do so.
  • Strong – It is engineered to withstand strong winds, rain, snow, or even tornadoes depending on your location.
  • Energy Efficient – A post-frame building offers adequate insulation because no studs are existing on the centre resulting in better insulation between the supporting beams.
  • Customizable – After building your pole barn, you can customize it to make it look like your dream building or house.
  • Requires Short Time to Build – You can finish off its frame in one week, and proceed to sort out plumbing and electrical features for your building in the second week.
  • Environmentally-friendly – A pole barn requires fewer construction materials and less energy to build, which makes it also a cheaper option aside from being an environmentally-friendly choice.

Additional Items To Plan for a Post-Frame Building

Despite the advantages it has, there are also some other items to plan before deciding to build your post-frame building.


Depending on where you live, you might need to obtain a permit before starting the construction of your pole barn.


You need to ensure that the poles are properly anchored into the ground to prevent them from toppling over in case of strong winds or earthquakes.


Proper insulation should be installed to maintain a comfortable temperature inside the pole barn, especially if you’re planning to use it as a home.


You need to install proper ventilation to avoid condensation and moisture build-up inside the pole barn which can lead to the growth of mold and mildew.

Windows and Doors

The number of doors and windows will depend on the purpose of your pole barn. If you’re going to use it as a storage space, then you might not need any doors or windows. But if you’re planning to convert it into a living space, then you need to install them for natural lighting and ventilation.


The roof is one of the most important parts of pole barns because it protects the building from rain, snow, and sunlight. There are a variety of roofing materials you can choose from but make sure to pick one that’s durable and can withstand extreme weather conditions.

Now that you know the basics of post-frame construction, you can start planning to build your small pole barn. Just remember to consider the items listed above including premium grade lumber to ensure the success of your project.
