"Tom was very easy to work with! He always asked what we wanted while building our home and was very patient with our questions. He has always been very timely and responded to any questions we had! We would highly recommend him and his crew! And he and his crew also built our shed for us after our house was completed. They did this with no concerns and was very prompt!"

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.

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.

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. 

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.

Whether building a playground or installing a pre-made one is more affordable depends on the materials of each. In most cases, it’s more affordable to build a wooden playground than it is to buy one and have it professionally installed, but it might be less expensive to invest in a pre-made plastic playground, even if you pay a professional to install it. Wooden playgrounds tend to last longer, but as children age, they will become less valuable. Overall, it may be most affordable to have a pro install a pre-made plastic playground.
