"I could not be happier with the work Robert and Overall Builders did in our house. Overall Builders demoed and remodeled our entire basement. There were outside factors that delayed the timeline of the project drastically and Robert was extremely accommodating and understanding. Robert was consultative throughout the whole process and was truly a pleasure to work with. I would honestly trust Robert with any home remodel or repair that I needed (no matter how big or small the project)."

"We had more than 80% of the old house remodeled with new additions. It’s a daunting task and huge project. However, Dimitritis and Joshua made it easy and did a great job in completing our dream home. Joshua was fantastic managing the daily tasks and excellent with details. They were very responsive in re-addressing even with minor adjustments. Definitely recommend."

"It was a difficult project. It’s one of those small houses in Nortbrook where they are predominantly have car ports instead of a garage or a garage that was converted to an extra room. It was a project with many challenges structurally as well as meeting the strict NB codes. It was more than we thought price wise but again things came up unexpectedly. Ricky is a very clever and experienced guy, fantastic. Throughout the short journey was Ivona. Ivona is very responsive and gets back to you immediately. They are so lucky to have her. Thank you again Ivona, Ricky and the guys. I am so glad I went with this company. I love my garage."

"I can't say enough about A P Builders and how absolutely wonderful they have been from start to finish. We completely gutted and remodeled our home and Angelo was upfront, honest, timely, and everything that was contracted was done to perfection. We had crew there every day from start to finish. He started on time and finished on time. Any change orders were handled professionally and solutions were found for any unforeseen challenges due to the age of my home. I highly recommend AP Builders for any of your home improvement needs."

"I hired Lucky Gorman to assess an exterior door between our outdoor balcony and hallway. The original builder did not install and seal correctly and water was getting into the unit as a result. Lucky and his associate Christian were knowledgeable and responsive. They sourced a new door and also replaced the wood trim and baseboard that had water damage. The quality of the work was great and I would hire them again ."

"It was great to work with Icon Builders to building our dream home. They went out of their way to accommodate the completion of our home build in time for school. Their response times are great and the staff is truly personable. It was great working with Jenna, Natalia, Joe, Scott, Shawna and Charlie. I will recommend Icon to anyone looking to build a custom home."

Barndominium Builders FAQs, answered by experts

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.

The best lumber for building will be the strongest and most eco-friendly wood your budget allows. That being said, Douglas fir, pine, oak, and maple are all common building materials. Contractors will use a strong, inexpensive wood to frame a house or other structure and finer woods like mahogany for detail work. 

The construction stage is almost always the longest part of building a house. Within this stage, framing often takes the most time, lasting anywhere from one week to a couple of months, depending on the home's size, the crew, and the time of year. Other parts of the construction phase include pouring the foundation and installing doors, windows, a roof, siding, drywall, and flooring. The planning and design phase can also be very time-consuming, sometimes taking months or even years, especially for a custom home. The final finishing process, which includes painting and installing trim, is typically shorter than the construction or planning stages.

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.

If you’re building a pole barn in place of a traditional home, lenders usually don’t offer traditional mortgages for these structures. You can also expect higher insulation costs and building permits may not be allowed in your area. Even if you’re just using a pole barn as storage or as a shelter for animals, these structures are less durable than steel buildings and require more maintenance.
