33 Free DIY Tree House Plans – Amazing Treehouse Designs

tree house plans

Surely when you were a child you must have dreamt of having a treehouse. Not necessarily for covert missions but to hang out and feel cool.

Well, I did too. And even now as an adult, while most are turning their basements into their safe haven, I fancy a treehouse.

But with some little digging, you will soon discover like I did, the insane price tag that comes with having a professional build one for you.

But before you move on, you still can have your treehouse without necessarily selling your kidney. I have taken the liberty to prepare a list of free treehouse plans to inspire your next DIY project.

Ultimately it is up to you which treehouse you build. That said, let us get started.

If you like these free tree house plans, you may also like ones for building a playhouse, tiny house, gazebo, deck, shed, and many more. 

Assuming you have gathered all the relevant information you can start building. Here are some steps to follow when building a sturdy and secure treehouse.

1. Build the Platform

This is an integral part of the treehouse. As such, you should build it carefully and securely around the tree trunk. For support, you will need to use diagonal braces.

The number of braces you use will, however, depend on the number of branches the platform will rest on. For nails, you should use screws and nails to ensure no rusting takes place.

Additionally, you can use a rope to secure the platform. But for this, you should know the right knots to use. After securing the platform, you can proceed to add an exterior plywood floor.

2. Grant Access to the Treehouse

In the planning stage, you should have already considered how you will access the treehouse. If a ladder, whether attached or separate is not a feasible idea, then a strong rope will work just fine.

You could also add a rope pulley to get items up to your treehouse.

3. Windows and Doors

Since you might not be installing windows and doors but might leave the spaces open, you can engage your creativity. Just ensure that the openings are in the right place and in the right proportions to the house.

4. Deck and Railings

If the treehouse design can accommodate it, then by all means plan for it. A deck would be a great addition to your treehouse.

You can add the deck later on as an extension or make it as part of the platform. However you do it, a deck will provide you with a nice spot to get away from the heat inside the treehouse.

5. Repairing and Maintaining the Treehouse

When the treehouse is complete, you still will need to regularly check it for rot or any structural weakness that may cause damage. Also constantly check your tree for growth that you may need to account.

If you notice any weak point, perform repairs immediately.
