Barndominium Builders FAQs, answered by experts

You may need a local building permit and written permission from your homeowner’s association to install a shed, especially if you’re doing any substantial land clearing or installing electricity or plumbing. Permit requirements vary between municipalities, so research the local laws before starting your project. If you hire a contractor to build the shed, they can help determine which permits will be necessary.

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. 

Skid foundations, deck block foundations, and concrete block foundations are the most affordable shed foundation options. Of these, we recommend deck blocks. Deck blocks are easy to install and level, and they raise your shed up off the ground to prevent rotting from exposure to water and moisture. Keep in mind that deck blocks won’t resist soil movement or frost heave, so they’re not ideal in areas with expansive soil or a deep frost line.

While building a treehouse isn’t necessarily a death sentence, damaging the trunk is one of the ways to kill a tree. If you’re concerned about the tree, opt for a treehouse support system rather than attaching it directly to the trunk. This may involve using bolts and brackets to affix the structure to the tree's branches or establishing a standalone support system that remains unattached to the tree.

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.
