"The project was completed on site exactly as I was expecting it to be and more. Oliver made some suggestions regarding upgrades and responded to my requests for additional small changes as the project proceeded. He was very efficient with his time and a most friendly and enjoyable individual to have working on my project. I would not hesitate to recommend Oliver to anyone as he is an exceptionally qualified and professional individual who is reasonable and was right on with his cost estimates."

Barndominium Builders FAQs, answered by experts

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.

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.

Whether you buy a prefabricated shed or build one depends on why you need it and where you stay. For instance, if a simple garden shed is what you’re after, it’ll be less expensive to buy one already built. But if you want a shed with windows, plumbing, and electric work, a custom-built unit might be more suited to your needs.

Building a tiny house is the least complicated way to build, especially if you’re tackling the project as a DIY. The smaller size means less complex plans, more straightforward utility installation, and fewer ways to make costly errors. Tiny homes still need to conform to building codes and often have other applicable regulations, so be sure to get the proper permits and confirm your build is by the book.

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.
