What you need to build a treehouse

A lot of work and equipment goes into building the perfect treehouse, but anyone can do it with the right instructions. A treehouse should feel like an outdoor oasis with the comfort of being indoors. This cozy space up in the trees is perfect for people of all ages and is worth the complex build. What starts out as pieces of wood can turn into a lifetime full of memories for generations to come. When building a treehouse, consider the materials that you will need to make it, the tools that you will use and the time that it will take to build. 

What to know before building a treehouse


Purchasing fixed plywood or bamboo from an online retailer will save you time in the process of building a treehouse. Plywood is dependable for wet weather. However, its thickness prevents drainage and ventilation. That being said, this material is best suited for the floor of the treehouse rather than the walls. Separated plywood boards will allow ventilation for the walls and an authentic look, builders can spend extra time weaving branches throughout.

The roof of the treehouse should angle 30-50 degrees depending on the amount of snow and rainfall in your area. Apply cedarwood on top of plywood to allow rain to run off the roof effectively. Though glass windows are clearer and scratch-proof, plastic windows will not shatter and are a safe alternative, especially if children are expected in the treehouse. 


Due to the number of various materials that require assembly, there are many different tools that go into building a treehouse. Before building a treehouse, consider investing in safety goggles and gloves, as there will be the use of saws and drills during the building process. To ensure that your measurements and angles remain accurate, it is vital to purchase a level and a speed square. Making sure that all of the measurements are accurate will save you time in the long run.

Aside from inexpensive measuring tools, you will need heavy-duty equipment, such as a circular saw, a drill and a drill bit. Among other small items you will need to purchase a couple of folding sawhorses as a sturdy table to saw the wood. 


The time it takes to build a treehouse will depend on the complexity of the blueprint. A simple backyard treehouse mounted high up in a tree could take anywhere from two to six weeks. If you are planning to take on a bigger project and build a larger commercial treehouse, it could take anywhere from six months to a year and may require a permit. 

How much you can expect to spend on a treehouse

The money that it takes to build a treehouse will vary depending on the quality of the material, where it is shipped from and which tools are needed. A small treehouse with basic materials will cost anywhere from $400-$600 while a commercially built treehouse can cost anywhere from $2,000-$4,000. 

Tips for building a treehouse

  • Allow gaps around parts of the tree with branches to accommodate growth over time. 
  • Add spacers between the floor beams to allow for movement of the branches.
  • Craft the walls with plywood boards to allow for ventilation. 

Building a treehouse FAQ

What is the best type of tree to build in? 

A. The best tree to build a treehouse in will be a deciduous tree. The types of trees that will provide enough support for a treehouse include oak, ash, cedar, beech and maple. Make sure the tree that you build in, no matter the type, is healthy and mature. 

How will my treehouse be affected by tree growth over time? 

A. Trees expand in layers. As the tree grows layers, the bolts of the treehouse will be absorbed into the tree. Depending on the growth rate of the tree, the bolts should hold and can be supported by adding metal pipes throughout the gaps when needed.
