"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."

"Job went perfect. I was approved for financing the day I called. When the contractor came out for the bid, he made a materials and labor suggestion based on our needs. The original estimate of 9k worth of unnecessary privacy fencing, that I could not afford, went down to 2.5k of sturdy chain link providing a safe play space for our rescue dog. The contractor said they are more interested in helping customers out than making large sales. The fence is very professional. It is even wired into the ground so our dog cannot dig under it. The city inspector said it was a "perfect" construction job. Finished in under 8 hours. Roughly 100 feet of chain link, posts, concrete, plus gate. High quality materials and the yard was spotless when the job was finished. Very trustworthy. I feel strongly that I got what I paid for. Peace of mind that my dog, a known short fence jumper, is safe as well as my yard and padlocked gate. The most important part, is that my dog LOVES the freedom of having a large yard to run freely in."

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.

Your chicken coop needs to be off the ground to protect your chickens and avoid problems brought on by flooding, mud, and moisture. If you can't locate a high area to build the coop, you should build an elevated coop to ensure it stays dry. 

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.
