"I needed my deck stairs repaired. This involved raising the top of the stairs up into place and engineering a beam system to support the. Ethan responded promptly and offered a solution at a reasonable price. Ethan is a hard worker, very efficient, and doesn't stop until the job is done, plus he is a nice guy. He is now on my go-to list for home maintenance."

Barndominium Builders FAQs, answered by experts

Choosing a suitable backyard playset that’s age-appropriate and entertaining for your children is worth the cost. A backyard playset you can update and upgrade as your kids grow offers even more benefits. Although a playset won’t substantially increase your home’s value, it won’t negatively affect it either.

While prices fluctuate because of increased demand, fewer supplies, and engineering time, OSB generally remains more affordable than plywood at $1 to $2.40 per square foot compared to the $4.50 to $10 for plywood. Cost is only one factor you should consider when deciding between OSB and plywood.

Building a barndominium means converting a barn into a house. Barndominiums are becoming popular as spacious and stylish alternatives to typical housing structures. Old barns that become houses traditionally consist of wooden construction. However, newer structures, such as pole barns, often contain metal exteriors and roofs. Converting a metal outbuilding into a house presents an excellent opportunity to create a barndominium from metal.

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. 

It is almost always more affordable to buy an existing home than to build a new one. Building a home involves numerous costs, including labor, permits, inspections, utility hookups, and brand-new materials, finishes, and appliances. Additionally, new construction loans can have higher interest rates than traditional mortgages, and property taxes on new homes are often higher, increasing long-term costs. An exception is a DIY house build, which can be cheaper than buying an existing home if you do the labor yourself. While building is generally more expensive, a new custom home offers complete control over the layout and design. Furthermore, new construction is typically worth more than a comparable pre-owned home and may provide a better return on investment if sold quickly.
