Best Wood Species for Your Backyard Tree House

Tree House
You've got a strong, healthy tree that's perfect for building a treehouse in. When designing a tree house for your backyard, selecting lumber that will last and look attractive is key to a successful build. There are many types of wood commonly used in all kinds of construction, including pine, fir, spruce, and other woods.
The primary concern with a backyard tree house is this: weather resistance. When you select the right wood species for your tree house project, you'll achieve both natural moisture resistance and durability.
Use this guide to help you choose the best wood species for your tree house project. Make a blueprint of your project's dimensions so you buy the correct amount of lumber at your local home building supply store.
Cypress is a dense wood that is easy to work with, making this a lumber worth considering for a tree house project.
Cypress is most known for its natural rot-resistance qualities, which keeps the wood from swelling and warping after being exposed to the elements. Due to its compact nature, cypress is also insulating so keeping comfortable while playing inside the tree house in various weather conditions won't be a large concern.
Cypress has the benefit of being readily available in the US, which makes this lumber cost-effective. Use cypress for your main tree house design - the main structural sides and roof of this outdoor play area. You can use a softer wood, such as pine, for interior flooring if you want to vary the lumber types in your tree house project.
While in general staying away from softwoods for the majority of your tree house construction is a good idea, Douglas fir is durable and reliable, making this softwood a wise selection for your outdoor project. Douglas fir is known for its sturdiness, so if you're worried about building a tree house in an area where it's windy much of the time, this is a wood to consider.
Since fir, like many wood species, is not naturally moisture-resistant, always have your lumber treated with a UV ray and water-repelling sealant to prolong the lifespan of your tree house over time. Your home construction supply specialist will help you choose between treated and non-treated lumber ideal for your exterior project.
Redwood is a common wood used in many exterior wood projects, from decks to fencing. This wood is rot-resistant like cypress and has a beautiful natural finish.
Redwood can be painted or stained in custom colors, but is often left alone aside from periodic sealing to allow the natural reddish brown color to stand out. To keep redwood from splitting while building, use caution when drilling holes in this durable wood.
White oak in particular is extremely hard and durable, ideal for creating a large tree house that will last. White oak is dense and able to keep most moisture at bay so rotting and wood warping is less of a concern with this hardwood than with other species.
White oak does crack when it's split, so buy your lumber pre-cut in the dimensions you need and use appropriately-sized nails or screws and a well-powered drill when building with this wood to protect its integrity.
Non-Wood Material
You can also use decking material to build a tree house if you want the structure to have a more contemporary design. Many decking materials have composite exteriors to create a moisture barrier that will allow your structure to last for many years.
Always create a project plan before buying lumber for your home projects. You'll also need to make a list for other needed supplies, such as window glass, fasteners, bolts, and other items.
