"Tom was very easy to work with! He always asked what we wanted while building our home and was very patient with our questions. He has always been very timely and responded to any questions we had! We would highly recommend him and his crew! And he and his crew also built our shed for us after our house was completed. They did this with no concerns and was very prompt!"

Barndominium Builders FAQs, answered by experts

Yes, barndominiums are designed to withstand strong weather and severe storms if they are built properly by trained professionals. Most barndominiums are made up of a steel structure that can protect a building from winds of up to 150 miles per hour and resist a variety of weather conditions without a major risk of structural damage to the exterior, foundation, or frame.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

It may be tempting to DIY the construction of a swing set to save money, but we don’t recommend it. Since children will use the swing set, the entire system must be solid and safe, meaning the cost savings aren’t worth potentially endangering them. Plus, most DIYers will have to build their swing sets out of wood, which won’t last as long as metal or vinyl and introduces the risk of splinters. Instead, hire a local playground equipment installer to ensure the swing set is built safely and efficiently, setting up your kids for fun for years to come.

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.

Choose a barn door with an extra two to three inches on either side of the frame. The width of the barn door will depend on the type and placement of your track, but in most cases, an additional inch or two will do the trick.
