"Oh we can't say enough about Rueben and his crew.. the work was top notch and talk about craftsmanship, there is no comparison.. we were on a budget and they came through and made everything work. We had a sunroom and bath added to our h ome and we just love them. The crew of guys were always very polite and just a great group of young men doing the best job we could of imagined. Ruben was always on top of the job, making sure things were done right. He came every day to check on his crew and asked if we had any concerns. So on that note if you need any construction on your home or business give this company a call, you won't be sorry."

"First and foremost, Coach House builds an excellent garage. They use their employees, and it was put up in one day. The issue is with their sub contractors -specifically the concrete and electrical. The rainy spring delayed the pouring of the concrete, which they could not help. Once they completed the pour, it appeared as though there were rough spots on the floor. I sent pictures to my sales person and his sales manager and was told it was concrete dust. The ridges were clearly visible in the picture. Then I was told it was discoloration and would “cure” over time. No one came out to visually inspect the issue until much later in the build project. Weeks later, the crew came out to do the build and they did a great job. Punctual, thorough, and as mentioned, built a very nice garage. Then we waited for the electrical. They had to make three trips because, 1st they did not have the correct PVC pipe after digging the trench. A week and half later, after having a deep trench left open, they returned. The journeyman electrician left the fuse box ajar, a 1/4” gap where they cut the drywall, the exterior lights on either side of the garage were hung at different heights (I had clearly marked them with masking tape as instructed by the salesperson) and screwed the base of the lights directly into the garage wall vs. using the brackets that were provided. At this point, our frustration level was pretty high. The electrical issues were fixed, and my sales person finally came out to look at the concrete. Realizing there truly was an issue with the concrete, their first solution was for us to have an epoxy floor put down. Second solution was to go halves on an epoxy floor. Neither option was acceptable as we should not have to pay for their mistake. They finally offered to take care of the floor at their cost, but at this point, we had already waited for 4 months for the garage to be complete, and frankly did not want any more of their subcontractors to do any work. After much back and forth, we finalized the invoice. Again, the garage itself is great, but there were too many issues involved with the rest of it."

"Ervin has done several projects for me over the past three years, most notably, residing my house. Using James Hardie siding, this wasn't easy, however, Ervin did an excellent job! Ervin is a high character guy! Unlike most contractors, if Ervin says he'll do something, it's like money in the bank he'll have it done in the estimated time frame. Knowing that I've had health problems and have been limited physically, Ervin has helped out on many occasions; that's the kind of guy he is. I would hesitate to recommend Ervin for any of your contracting needs."

"Based on our past experience with AOM (interior painting), we used them to powerwash our home. They had all the appropriate equipment and did an excellent job. Our 20 year old vinyl siding looks totally refreshed. David is easy to work with and goes the extra mile. We will continue to AOM for future projects.

"HIGH QUALITY job. The estimate was the highest one I received, but the materials were far superior to all others. These look great, SOLID INSTALLATION.  Took away existing gutter that was installed.  Professional from the estimate to the install.  Showed me that he had worker's comp insurance on his workers as well as being licensed and bonded.  Home owner's insurance does not cover hired workers on home improvement projects.  Very important."

Barndominium Builders FAQs, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

In the U.S., original and converted carriage houses are most often found in New England, New York, and other parts of the Northeast. New construction carriage houses can be found across the country, and are often added to properties with Colonial-style homes for additional living, storage, or work space, although they can be found in many different styles.

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.

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.

Skid foundations, deck block foundations, and concrete block foundations are the most affordable shed foundation options. Of these, we recommend deck blocks. Deck blocks are easy to install and level, and they raise your shed up off the ground to prevent rotting from exposure to water and moisture. Keep in mind that deck blocks won’t resist soil movement or frost heave, so they’re not ideal in areas with expansive soil or a deep frost line.
