"We had a pretty big project, removing an old camp roof and building a new roof rotated 90 degrees, and adding a loft area. We were very happy with Andrew and his crew. They really go the extra mile to make sure everything is done right - they don't cut corners and take pride in their work. They installed new windows in the front and even used Windex to wipe off their finger smudges! Price was very good, and they're good, honest guys to work with. Very pleased!"

"Did a great job. Built mailbox stand with an excellent custom flair. Built for strength. Texted and came right away. The message transition to know who was talking to me was confusing at first. DP was also not sure who it was initially."

Barndominium Builders FAQs, answered by experts

Tiny houses, often called tiny homes, need between 100 to 400 square feet, with the most common size being between 200 and 300 square feet. Tiny houses more than 400 square feet venture into apartment-size dwellings and may be considered more of a traditional house than a tiny home. The number of occupants, desired lifestyle, and furniture will all be major factors that determine the desired tiny house size.

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.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

The difference between a pole barn and a stick-built barn is in the construction. Large poles in the ground provide support for pole barns. For stick-built barns, 2-by-4 or 2-by-6 lumber (known as sticks) create a frame around load-bearing beams. Stick-built construction is far more popular for residential homes. Pole barns are more cost-effective because they require fewer materials and less labor.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.
