"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

Complex plumbing is tricky and expensive in an off-the-ground dwelling like this. By considering options like composting toilets, rainwater collection, and gray-water sinks, you save money and help the environment. 

Your chicken coop needs to be off the ground to protect your chickens and avoid problems brought on by flooding, mud, and moisture. If you can't locate a high area to build the coop, you should build an elevated coop to ensure it stays dry. 

Technically, most states allow tiny homes, but it depends on the definition of tiny and whether the structure is permanent. Zoning laws regarding home size and construction are significant factors. For instance, a tiny home may be legal as a recreational vehicle in most areas, but you may only install it on a property if it complies with building and zoning codes.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

Pole barns and carports are similar in that they rely on posts for support and are often not connected to a primary structure. The main difference between the two is that pole barns usually include walls that surround the entire perimeter of the structure, while carports generally remain open on three or four sides. It’s possible to insulate garage doors and even exterior walls on pole barns to create a comfortable workspace, and it’s a bit more secure for storage purposes. However, carports are more affordable.
