"Steve was very conscientious & personable. He installed my smoke alarms efficiently and professionally. He also helped with a few other minor electrical issues in a quick and thorough manner. Before leaving, he wanted to be sure I was happy with the work and offered that he is able to perform a variety of home repair/remodel/construction related tasks. I will definitely be contacting him in the future!"

"We recently hired Dustin with All In One Construction completely remodel our kitchen and master bathroom, and I cannot say enough good things about them. From the very first meeting to the final walkthrough, they exceeded every expectation we had. His team was professional, punctual, and respectful of our home and our time. Dustin was responsive, transparent, and kept us informed every step of the way. He truly listened to our vision and turned it into something even better than we imagined. The attention to detail was great, from the perfect alignment of the tiles and cabinetry installation to the lighting and finishes. Everything looks custom and high-end. Dustin's team showed up when they said they would, cleaned up every single day, and never cut corners. If any unexpected issues came up (as they sometimes do in remodels), they handled them quickly and fairly. Very happy with the work they did. Thank you Dustin"

Barndominium Builders FAQs, answered by experts

The lifespan of a barn is typically 40 to 60 years, but with skillful construction and proper maintenance, it can last up to 100 years. The actual lifespan depends on several factors, including the barn type, materials, usage, and climate. For example, the posts of a pole barn should last 50 years or longer, but if the structure is used for livestock in a rainy climate, it may rot within the first decade. Custom designs with high-end materials tend to last the longest. To get the best estimate for your barn's lifespan, you should consider its material type and intended use.

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 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. 

A 5x8 trailer can fit a queen-sized bed plus additional items. It is one of the most common sizes for enclosed cargo trailers, open utility trailers, and dump trailers. U-Haul, a national trailer rental company serving most U.S. markets, claims its 5x8 enclosed trailer can tow up to 1,800 pounds.

The timeline to build your barn will depend on the barn type and the company you hire. A pole barn may take six weeks or so, while a traditionally framed or steel-framed barn can take four months or longer. Building a barndominium takes the longest because you are essentially building a new home. You can expect barndominiums to take six months or longer to build.
