"We had Garden Structures & More add onto the beautiful privacy fence they had previously built for us, and we couldn't be happier with the final result. Our new and improved fence is even better than we had envisioned due to owner/designer/craftsman Hal's excellent ideas. All work was completed in a timely and professional manner. We truly enjoyed working with Hal and wouldn't hesitate to have him do our next home project. "

Barndominium Builders FAQs, answered by experts

The best lumber for building will be the strongest and most eco-friendly wood your budget allows. That being said, Douglas fir, pine, oak, and maple are all common building materials. Contractors will use a strong, inexpensive wood to frame a house or other structure and finer woods like mahogany for detail work. 

If you’re building a pole barn in place of a traditional home, lenders usually don’t offer traditional mortgages for these structures. You can also expect higher insulation costs and building permits may not be allowed in your area. Even if you’re just using a pole barn as storage or as a shelter for animals, these structures are less durable than steel buildings and require more maintenance.

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

The foundation for a pole barn should be at least 36 inches thick to ensure that the piers won’t shift from frost heave.

While prices fluctuate because of increased demand, fewer supplies, and engineering time, OSB generally remains more affordable than plywood at $1 to $2.40 per square foot compared to the $4.50 to $10 for plywood. Cost is only one factor you should consider when deciding between OSB and plywood.
