"They did an excellent job. They were expensive, but you get what you pay for. The building inspector of the city said this was the best built garage he had ever inspected. I would highly recommend them and I would definitely hire them again."

"Mr. Handyman was wonderful! Not only was the clearing done perfectly and safely, but under the time quoted. Without Mr. Handyman, I could not have made it out of my home for days! I am not looking forward to another storm, but I feel a lot safer that I have someone to help me. I have had terrible experiences with contractors in the past, and I won’t hesitate to call Mr. Handyman."

Customers say: True professional

"Had my over sized two car garage floor removed and replaced due to poor condition of old concrete. Their workers are very hard workers and the job turned out perfect. Steve is a great guy and provided fair pricing and good communication. Easy to work with and would recommend the company for any of your needs."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

Barndominium Builders questions, answered by experts

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.

Tiny houses, often called tiny homes, need between 100 to 400 square feet, with the most common size being between 200 and 300 square feet. Tiny houses more than 400 square feet venture into apartment-size dwellings and may be considered more of a traditional house than a tiny home. The number of occupants, desired lifestyle, and furniture will all be major factors that determine the desired tiny house size.

The difference between a pole barn and a stick-built barn is in the construction. Large poles in the ground provide support for pole barns. For stick-built barns, 2-by-4 or 2-by-6 lumber (known as sticks) create a frame around load-bearing beams. Stick-built construction is far more popular for residential homes. Pole barns are more cost-effective because they require fewer materials and less labor.

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.
