"So happy we chose R&D for our exterior wall repairs! they were great to work with throughout the process of what turned out to be a complicated issue. Their communication was really appreciated as they dug into things and problem solved some unique issues with how the previous home owners had cut corners on the house. R&D wasn’t the cheapest initial bid we received but I have no doubt that we would have wound up paying more in the end for a lower quality result with anyone else. Thanks guys!"

"I could not recommend Harold's Enterprises more highly. I reached out to Harold based on his listing on Angie's List before I bought my home--free of charge, he took a look at the roof on a property I was considering buying--giving me an estimate and advice. His help led me to find that the sellers were dishonest about the condition of and work done on their roof, and I purchased a different property in Hudson, NY. My home is a 1927 Craftsman that needed quite a bit of work. I hired Harold based on his honesty and responsiveness in helping me evaluate the first property. True to form, his estimate and ultimate cost to repaint the entire interior, repair and sheetrock floors and ceilings, refinish and replace hardwood floors, completely remodel a bathroom, rewire and install light fixtures, match original woodworking, install cabinetry, windows, and appliances, and even assist with installing new furniture, were more than reasonable. Better yet, the quality of his work was of the highest caliber. He has restored and improved a lovely home, and I am so thankful! I have to say that most of all, I am so happy with Harold's professionalism and diligence. Not every contractor is known for staying on the job and completing it on time. Especially in my situation, where I am a single woman trying to restore a second home when I live out of state--I assumed I would have difficulty in getting any contractor to be present and complete the job on time. However, this was never a problem. Harold was always there, was immediately responsive, and never slacked off when I wasn't there. I plan to work with Harold as much as possible in the future as I continue to improve my Hudson home. I recommend him very highly."

"Alan and the employees of Crowe Town Construction are a part measure to work with. They treated us and our house with respect. An ugly old bathroom has been turned into a picture in a magazine!! We especially love the tile work that was done. If you have any work that needs doing we recommend Cross Town for the job. You can trust them."

Barndominium Builders FAQs, answered by experts

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.

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.

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.

It’s much less expensive to build a house with wood. This is because wood is relatively inexpensive, strong enough to endure decades or even centuries of weathering and pressure, and is easier to replace if there are issues. The cost of stone houses are incredibly expensive, heavy, time-consuming to build, and difficult to repair. 

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.
