"I hired Kevin Martin (H. Hedges Home Improvement) to build a new deck, replace a bathroom floor, and repair kitchen cabinetry. Kevin's quote was very competitive and fair. He and his crew showed up exactly when they said they would. He was very collaborative and his communication throughout the project was excellent. It is clear that he wants his customers to be happy at the end of the day. Our HOA also hired Kevin to replace fencing for a 14 unit association and build a new enclosure for a dumpster. Again, his bids were fair and competitive and he performed quality work. I would not hesitate to recommend him."

"Tim and his team were fantastic. We planned for a significant renovation including several structural elements, carpentry, electrical, and siding and Horsman Builders delivered. Tim was a reliable communicator and addressed our questions in a timely manner. We replaced an entire roof, added walls, doorways, re-did a deck and covered porch, replaced doors, replaced siding, and added new outlets- to name a few. We felt like we could really trust Tim and plan to work with him again in the future."

"Boyd Building had done some work for us in the past so when we needed a major deck and porch rebuild and finish, we knew Shawn would be the only one to call. Shawn always goes above and beyond in planning and executing our projects. He once told me that he puts the same amount of quality and care into the work he does on a customer's home as he would on his own home and I truly believe him. His work is detailed and meticulous. The job he did remodeling our outside space is top quality. There is not one thing we had to question. We love everything! Beyond that he is reliable, honest, trustworthy, hardworking and a really nice guy. We can't possibly recommend Boyd Building any higher! 5 stars don't seem like enough!"

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

"Costas and his team did a wonderful job on my Aunt's home. What started off as a deck repair, turned into so much more (siding, windows, new 1/2 bath). The house had been in a bit of disrepair and he was very thoughtful and thorough in his approach to bringing it back to life. My family and I will enjoy it for many years to come, and I truly appreciate some of the little things he did along the way to ensure everything was done right. He took the initiative to select things when I was not able to be there. It felt very much like he was treating as if it were his own home. His attention to detail was terrific, and he was super responsive. THANK YOU again!"

Barndominium Builders FAQs, answered by experts

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.

You can use a variety of wood to build a barn door, but the most common options include 1-by boards and 2-by boards for the backing and the decorative boards on the front of the door. Softwoods like pine will save you some money and should hold up well, while hardwoods like maple and oak will stand up to more wear and tear. You could also build the backer out of plywood to minimize the cuts you need to make. Whatever you decide on, make sure the width of the wood is compatible with the mounting brackets you buy.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Depending on your needs, you may find a storebought pole barn is a much less expensive option than a custom-built one. You can find pole barn kits from big box retailers starting at $11,000, but you will be limited when it comes to size and add-on features. As long as you have the necessary skills, you can save on labor costs by doing it yourself; but there are a lot of different skill sets you would need, and mistakes during the building process can lead to excessive repair bills later.

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.
