Before you can do anything, you need to pick your tree. It needs to be strong so it can handle the weight of the wood. Plus the weight of anyone that will be in the treehouse.

The best trees for a treehouse are red maple or oak with a “Y” shape. You also need to think about the height. The advice from experts is to keep it around eight feet. Definitely no lower than six feet and no higher than ten feet.

Make sure to inspect the tree or even call in an arborist to inspect it. Make sure there is no tree disease and that it has no damage in any way. You’ll also want to check the roots and make sure they run deep and have a strong foundation.

If you are drawing up the blueprint yourself, make sure to write down, the sizes of everything. Like the walls, windows, and you might also want to add railing for safety measures.


Building the foundation will be your next step. As with the foundation of anything, it is the most important aspect other than the tree.

If your foundation is not strong and sturdy, your treehouse won’t be either. Make sure to use your level at each and every step.

This is the best way to make sure that your treehouse will be perfectly accurate.


Before you even start building your platform. You’ll need to decide which way you want your deck to go.

Plus you will be able to figure out which way the joists will go. You will want your joists to run vertically to the deck boards.

A tip when doing this is to make sure to drill the holes into the tree. Also, into the joists before trying to secure them to each other.

This helps to decrease the chance of putting cracks in your joists.

Make sure that all of the screws are tightened down once you have everything attached. Once this is completed you’ll need to add the rest of the joists.


Once that you have all of the joists drilled where they need to be. Then you will need to add the hangers you’ll use the galvanized nails.

For this, and they need to be at least one-inch long.


The next step is to add your braces. Braces are necessary to add more stability and strength to your foundation. Make sure that they are cut at a forty-five-degree angle.

Also, they need to be at least two feet long. Once they are all cut, nail them to the posts of the foundation with three-inch decking nails.


The next step is that you will need to attach your decking boards. Install your platform with your wood screws.

Remember that you need to cut around the posts. So, make sure to measure. The rule of thumb is to measure twice so you only have to cut once.


Time to cut the studs, make sure to measure twice! The framework needs to be at the height you’ve planned for the treehouse to be.

And the area of your platform. You will need to use a framing nail gun. Also, connect the platform with three-inch nails then add your studs.  Don’t forget about your windows and door, you have to frame those too.


To build a ridge beam you will need your saw and two by six boards. The best way to get this done is to make sure that your two-by-six are standing up. They will support the beam as you connect them to your frame. Place the boards at two feet on the center.


Time to get the siding done. Remember to measure twice. Nail your siding to the gable end walls. You will need two and three – eight-inch nails for this. Cut to get rid of any excess wood.


Using the reciprocating saw get the holes cut out for the windows and the door.


Measure and cut plywood, nail to the rafter with two and three – eight-inch nails. Don’t forget to leave the tree some room and make sure to leave at least a six-inch overhang.


Use your nail gun to nail the trim around the windows and door.


Take the time to install the railing around the deck. But remember, leave a spot for the ladder to go up. It’s just an added safety precaution but better safe than sorry.

Attach your ladder and you’re all done. You now have a strong, sturdy backyard treehouse! Make the most of it and enjoy.
