Bob’s Top Tips for Building a Treehouse This Spring

Chelsea O'Donnell

Last week we talked about some tips for planning a treehouse build. This week, I wanted to go over some of the basics to consider when taking this project on. Every treehouse will be different in terms of their size, shape, and configuration, but there are a few common rules to be aware of regardless of the type of hideaway you are building.

Keep Design in Mind

While many people prefer a more rustic approach, there are also hundreds of amazing treehouse plans that you can access through the internet. Check out which offers plans for every size and shape of house and which also includes a shopping list for all the lumber and equipment you’ll need. A treehouse with some pizazz can actually increase your resale value if you decide to move house after the kids have grown and gone.

Level the Floor

Building a structure that’s off the ground is tough, but it’s important to get the platform completely level with the weight evenly distributed between the tree branches or the supports. You can do this by laying the beams across the branches or running the beams between multiple tree trunks and then shimming them until they are level. If you’re building around the base of one tree, you can level it using your supports. Treehouses can last a lifetime and you want to make sure you get the first step right or the rest of the build is going to be more difficult.

Build in Pieces

Rather than trying to construct your house up in the trees, consider building each section on the ground first and then hoisting it into position using a backhoe or a pulley system. Generally, the four walls and the roof can be built on the ground and then assembled when it's on the base. Measurement is key here because you want to be absolutely sure your treehouse fits when it is in place.

Keep the Tree Healthy

Building a treehouse can put a lot of strain on the tree itself and punctures will leave it more susceptible to disease. Use floating brackets to allow for flexible support so the tree can move and sway in the wind the way that it's supposed to. You can purchase specialty fasteners that are made specifically for treehouses that will do less damage and keep the house secure. Also, remember that trees grow and the size it is now will change in 10 or 20 years time. Don't build too tightly around it.

Remember the Extras

A treehouse is all about imagination, so don’t be afraid to get creative with some fun add-ons. A tire-swing, zip line, ladder, bridge, fold down seating, water cannon or a fireman’s pole are some of my favorites. Also, consider making a pulley system to help kids get toys, snacks, and games up to the treehouse so they can climb in and out as safely as possible.
