How to Build a Treehouse


You've got a long holiday weekend ahead of you and you want to do something fun with the kids. You've been planning forever to get outside with them and build a treehouse that the can play in. You've got fond memories of your own tree house from childhood and want to make sure that your kids don't miss out on this special part of life. But you can't actually recall how to build a tree house. Looking back, you're fairly certain that the one you threw together as kids wasn't particularly safe. You'd like to spare your children the possible emergency room trips by building a better one this time around. How do you do it?

There are three main components to building a tree house: the foundation, the posts and the rest of the structure. You'll want to make sure that you attend carefully to the building of all three areas to make a tree house that is both sturdy and fun for the kids. The foundation and posts will be important to keeping the treehouse safe and functional. The design of the sides and roof of the structure will be what you can play around with a little to give a creative appearance to the tree house and make it picture-worthy. Combined together, these will make for a tree house that the kids will love and you'll feel safe letting them play in.

First you'll need to make sure that you find a sturdy tree. Even if the one that you have is great, you won't want the tree to support the entire weight of the tree house. This is where the posts come in. Assess the tree to determine how much of the weight of the tree house it can hold. You don't need exact numbers, just decide whether the tree itself will be the main post support for the tree house or only a supporting leg. You'll want to create a basic structure with four posts for the legs of the tree house. This keeps is sturdy. The tree may be one of these posts. Or you may design the four posts around the tree with the tree growing up through the center.

Second, you'll need the foundation. Your best bet for this part is to order some basic tree house plans (or find them at a local bookstore). There are many different ways to build the foundation of the tree house. Your choice will depend on the materials that you are choosing to use and the size of treehouse that you want. You can make something really simple by laying flat boards across the posts that you've installed and nailing them all together. Conversely, you can make something more elaborate. Find a design that you like and that also looks easy enough to construct.

Once you have the foundation and posts, you can be creative with the rest of the design. Consult your kids about what they would like. Come up with some neat salvaged materials, make some quirky angles and shapes. Test it out with your own weight (cautiously) to make sure that you haven't created anything that's too heavy for the foundation and posts to hold up. Consider an open-air model that protects the kids from elements while up there but doesn't necessarily keep them entirely enclosed. The point of being in a tree house is that you're in a tree.

These are the basics to building a tree house. Don't forget the perks as well. For example, you'll want a ladder for your tree house. It can be a rope ladder or a wooden one, a free-standing ladder or one that scales the trunk of the tree. You'll also probably want to help your kids make a sign for the tree house which labels it as their own. It might be a little too chilly now to make much use of the new tree house but the kids will be excited about it anyway. And come spring, they'll have a place to play that the neighborhood will be bragging about.

Don't forget to be kind to the earth when building your tree house. Use natural materials and salvaged woods for the construction. And don't put nails directly into the tree. Green building starts with small projects like this one!

When I move back home to Hawaii I have been thinking about building a livable treehouse on my property instead of a conventional house. Great article with good advive and I pinned it to my "Alternative Housing" board at

Paul Cronin from Winnipeg on August 25, 2011:

Great hub, I always wanted a tree house especially as a kid. Amazing there are actual instructions for building a live-in style tree house, thanks for sharing! Voted Up and interesting...

Jamie Brock from Texas on April 15, 2011:

What a cool treehouse!

denzeltan998 on January 27, 2011:

Had a great fun to read this hub.

i will definitely try your tips.

Really it takes me into my past when We had a tree house!

And I am fully agree with Richard Stephen point!Plant more grow more and save environment.

Great Hub.Regards!

Richard Stephen on August 05, 2010:

What a great hub! I have 3 kids that I would have loved to build a hub for. I have such great memories of my odl tree house. Unfortunately, the preponderance of tract homes today is killing chances for most kids these days. Tract homes just don't have trees you can build a tree house in. Sure, you can plant your own trees but your kids will be grown before the tree is big enough! Sigh!

Hey Lily! I'm thirteen too, but you know what? I think you can never be too old for a treehouse! Hahahaha(: Ok, well, just saying, about the whole thin trees thing, you could always build it on metal or wooden poles, but you could build it right up there in the trees, so that you could really get the feel that your up in one! And you could always let a few branches come through and stuff! You could even use one of the trees as one of the poles!(:



Lily on July 11, 2010:

hey im only thirteen and i know im a little too old for one, it's always been my dream to have a treehouse.You make it sound so simple. I deffinately want to build a treehouse now, one of my biggest problems is a sturdy tree. I live in Indiana so I am surrounded by trees(actually i practically live in a forest) but many of the trees are just too thin and not sturdy enough. If you have any advice please post. thx

animal-backpacks from Brighton on July 03, 2010:

It is my absolute dream to one day be able to follow these instructions on my own land. Until such time I'll just have to bookmark this page and look forward to a time when I can have one of my own.

Thanks for a great read.

Janae Nichols on June 16, 2010:

Awesome idea!!! I have always wanted a treehouse and now i really want to build one!! Better go start planning and working away!!! All i need to know is what are the basic miterials and where to get the flat wood you would use, and the other things.... oh well... i wish someone could help me with those. Also it would be nice for those things to be found in plano texas. Thanks...

Great idea, and that's a pretty awesome one in the picture!!! :)

ante on January 28, 2010:

Great tree house. Unfortunately, I don't have a big tree to build on it. Hmm... maybe, I'll plant it for my son

bengriston on September 10, 2009:

These are some amazing tree houses. My kids have been bugging me to build them one. I am afraid my carpentry skills are not capable of creating something like this though.

Joanie Ruppel from Texas on September 02, 2009:

Sure beats the treehouse we had when I was a kid. A part of an old fence panel nailed up in a tree. But it sure was fun!

jonty on August 05, 2009:

Erick Smart on March 31, 2009:

I just got some property with my spouse and this is an excellent idea for our children and for a fun family project this spring.

AshleyVictoria from Los Angeles on March 28, 2009:

That treehouse in the picture at the top is nicer than my apartment. Perhaps I should stop paying so much rent and look towards the wild for my living needs! Fun hub :)

Kate L Williams from Pacific Northwest on March 03, 2009:

I'd just like to come over and play in yours without trying to build my own! It has always appealed to me to spend a week in one of those resorts that have tree houses.


stanleyreese from Alabama on November 14, 2008:

Thank you, thank you! This is on my "to do" list now before my wife even mentions it. The kids will love it as they get older!

boom huis on August 01, 2008:

I found your page to be interesting and inspiring, so inspiring that I decided to build one with my daughter this summer! I even started a blog to track my "progress" come on by!

Michelle Simtoco from Cebu, Philippines on June 06, 2008:

I love the idea of a tree house, I have always wanted to play in one. :)

janestanley on May 07, 2008:

What a great lens. I never realized a tree house would need a foundation. I always just assumed that you would use the tree and hope for the best. In building my own house, however, we had to dig deep trenches for our home's foundation. We used an excavator for the project. I found this site to be quite helpful There is a lot of useful information about excavators and other building equipment. Drop by and check it out.

2patricias from Sussex by the Sea on April 20, 2008:

When I was a child my Dad built a tree house that was offially for my sister and me - but really it was for HIM. We enjoyed it all the same.

ElizabethParker25 on April 17, 2008:

Excellent tips on building a tree house! You make it look so simple! I prefer my house on solid ground though. Even if I have to dig deep for the foundation. They make for more sturdy and stable structures. Of course, I'll use proper construction equipment such as excavators and to make my job easier. For anyone interested, ExcavatorsGuide -- -- has a wealth of information about excavators and other building equipment. Feel free to drop by!

this was ok, I guess but what an amazing picture!

RainbowRecognizer from Midwest on February 29, 2008:

This is really nice!

Ashok Rajagopalan from Chennai on November 24, 2007:

Excellent idea! What fun!
