"I signed up on Angies list on 2/18/2017 and had the work done today. Tooltime got back to me on 2/21/2017 and we made arrangements to have the work done today. Mike from Tooltime was here at 9AM on the dot, he put the safety bars in and left the bathroom cleaner then it started. I will call on Tooltime again for more work in my home. If there were more stars to be awarded I would do that. Thank you Ivka"

"I can't say enough for what Arroyo Bros have done to transform my home. They have done (so far) remodeled a couple of rooms (kitchen and adjoining sunroom) that are absolutely beautiful. Not only that they discovered safety issues with missing support beams and engineered how to support my roof. It was a joy to have them work on my home."

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

"On a scale of 1-10, I would rate Brother and Brother Builders an eleven. Their professionalism, knowledge, craftsmanship, and courtesy were truly exceptional. During the initial meeting, the senior project manager Daniel Perez carefully guided us through the process and was available to answer any of our concerns. Then throughout the project, he checked in on a regular basis to ensure the process went smoothly and made sure everyone stayed within the projected timeline. The interior designer was amazing and extremely talented. I always appreciated how she listened to my thoughts when creating the final design. She was also readily available when needed. The foreman and crew were hardworking, respectful of our home, and accommodated our requests. The final product was beyond fabulous and we are extremely happy with our renovated kitchen and family room."

"We needed a new kitchen, since ours was seriously out dated. We have some ideas of what we wanted, but was hoping for some professional input. We hired Eli with Cal Green to do the job and had hoped we made the right decision. In the end we did. Eli was very knowledgeable, patient, and caring. He made the process go very smoothly and handled all the permits and dealings with the city, which was a relief for us. He took our ideas and included some of his and the kitchen came out great we are very pleased with everything. I would recommend Eli for any work you're considering for your home. For our next project we will definitely be using Eli and Cal green remodeling. Thank you so much Eli for a wonderful experience."

Barndominium Builders FAQs, answered by experts

While it’s best to have access to large, healthy, strong trees in a safe position, treehouse living is still possible without them. Contractors can fit tree posts to build the structure onto or use posts as additional support alongside the trees themselves. If you’re in doubt about the suitability of the trees on your land, consult with a local treehouse builder before you start the project.

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.

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.

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.

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.
