38 DIY Tree House Plans
1. The Modern Magic Kids Treehouse Idea
Building a backyard tree house for your children can be both engaging and educational thanks to these free plans. And this is not your run-of-the-mills tree house.
It stands on a set of wooden stilts, and it’s just a plywood framed-box. This means that it’s both easy to make or disassemble if there is a need for that.
For stability and safety, the builder recommends off-the-shelf steel anchors, and you can use standard beams, sheets, and board to build this children’s tree house.
2. The Treeless Team Blueprint
If you want to build a nice tree house but you lack the perfect tree, these free tree house plans will come in handy.
Your first step is picking the right spot to build this treeless house.
Instead of an ordinary tree, you’ll need a substitute – a small pole measuring 20 feet in length and 8 inches in diameter which you can buy at a lumber yard. There are detailed explanations and diagrams to help you along so don’t worry even if it’s your first DIY project.
3. The Wellness Mama Treefort Build
This cool tree house will not only be a spot for your children to play but it will also serve as a place for climbing and exercise.
The tree house has a climbing wall with a rope and an enclosed clubhouse area. However, this is a lengthy project, and you’ll need several hands on deck to help you build it.
You also should know that some aspect of the construction might be considered risky so read everything carefully before you start building the house.
4. The Apartment Therapy DIY Treehouse Design
This concept is a delight for any child, but it might seem like an impossible task to build one for an amateur.
But now you have this amazing tree house design suitable for people with minimal skills.
Thanks to it, you can build a simple tree house in a day with some scrap wood and branches. Just don’t place it high on the tree because it’s an open construction. And choose your tree very carefully – it must have strong branches starting high up.
5. The Kid’s Slide And Swing Idea
If you are looking for an outdoor plan for younger children, this is the design for you.
This amazing tree house is a simple self-supporting platform, which is built around the tree not in it, unlike traditional tree houses.
It features stairs with handrails to make it easier for kids to climb inside, a slide, and a set of swings. For older children, you can tweak the design and swap the stairs with a ladder.
6. The Cool Hanging Treehouse Bar Blueprint
Are you looking for a unique and fun plan? Then you have to see this design. It features a house with rounded walls, which hangs from the tree.
Moreover, it has a transparent roof to let natural sunlight, and there is enough room to lie comfortably inside. It’s essential that you follow the instructions to the letter because if you don’t reinforce the carrying beams properly, the construction might fall.
7. The Easy Treehouse Cottage Build
To build this backyard design, you need a tree with a canopy larger than the floor of your tree house.
The plans are for an 8 x 8 ft tree house, but you can change them if you have a larger or a smaller tree.
Moreover, there are detailed instructions with pictures available in a PDF file and a list of materials that you can print and go shopping.
8. The Backyard Kids Treehouse Design
This cool option will be an excellent addition to any backyard and will delight children of all ages.
It’s a slightly complicated construction so read the instructions carefully and get someone to help you with the heavy lifting.
Make the ladder with steps spaced at 10” to make it easy for small children to climb inside and add a 36” high railing for safety.
9. The Three Tree Crook Idea
An outdoor house like this one requires two or three branches in proximity (2-3 small trees will also work) and a couple of weekends to finish.
The builder uses pressure-treated wood for the floor and the support and an old fence for the sides.
What’s good about this plan is that you’re not going to build a roof. Instead, you’re going to use a camouflage-pattern tarp to keep the insides of the tree house dry.
10. The Pirate Hideout Project
Boys always dream to be pirates, and now you can build them a pirate tree house in just nine steps.
Keep in mind, though, that this won’t be a cheap tree house and it will take you around 100 hours to finish it.
Moreover, there are not many pictures to illustrate the building process, and the builder doesn’t mention all the hardware he uses so this plan is more suitable for someone with experience.
11. The Ultimate Kid’s Plan
The minute you see this family tree house, you’ll fall in love with it.
It has everything a child can dream of – slides, stairs, several decks at different levels, a sandbox, and a mulched play area. What’s more, beneath the much area there are 2” thick foam mats to soften any fall.
The roof is made of asphalt shingles to keep the rain out, and pressure-treated lumber is used for the exterior of this tree house fort. If you’re going to build out something that looks like a lofted tiny house, consider adding some DIY kitchen cabinets to really take it to the next level!
12. The Redwood Big Blueprint
If you happen to have a large tree stump in your garden surrounded by big trees, you can build yourself one which will be the talk of the neighborhood.
You’re going to use the surrounding trees as a support for the framing, copper pipes for the railings, and some old bedpost to add character to your construction.
Unfortunately, the builder doesn’t go into many details regarding the building process.
13. The Lumber Tree Platform Build
If you want a tree house that will add character to your backyard, this is the plan for you.
This beautiful tree house is built around the tree with a ladder that leads to the deck.
Moreover, there are three trap doors and corner seat benches for the children. You’ll need a lot of help to build this tree house so make sure that you gather all your family and friends.

Tree House Building Tips
Check out our roundup tree house plan video above- it’s a handy way to get an overview of the available styles!
Since we compiled so many different outdoor plans it only made sense to examine some general best practices when it comes to constructing them. One of the great benefits of owning a large property is the potential for erecting one of these adventurous structures. It’s frequently a right of passage for parents and their children.
Over at outsideonline.com they have some specific advice for prospective builders. The first thing they say is that since trees, obviously, grow and move, your treehouse will need to allow for that. They recommend that if your treehouse connects to more than a single tree it’s best to bolt it to the largest tree and use floating brackets for every other connection.
The second bit of advice they offered is to keep the number of holes you put in the tree as low as possible. The more holes you drill the likelier a tree can be infected with fungus or pathogens.
All of the penetrations should be spaced at least 18 inches from each other and should never form a straight line because that can cause a large gaping wound to open in the tree that could be deadly to it.
The third bit of advice is that you shouldn’t place wood against the tree because the wood will gather water causing the beams to rot. You can use an attachment bolt to ensure that your wooden planks and beams have a 3 or 4-inch distance from the tree bark itself.
Another interesting consideration is to project how far into the future you imagine you’ll still be using your treehouse. They advise making it large enough to accommodate adults or at least teenagers because it’s likely the treehouse will get some use even after your children have grown up.
Or imagine that your kids are going off to college and you’ve still got it in the backyard. You don’t want it to be a juvenile eyesore in your suburban neighborhood, so build it to last for a lifetime or make it easy to disassemble. Before you rush out into the backyard with your tape measure and hammer, take some time to peruse the different plans online to get a sense of all the different features you can add to make the treehouse splendorous.
For example, you can outfit it with long slides, zip lines, portholes, even rockclimbing walls. There are also some fun themes you can incorporate- making it a princesses palace, spaceship or a pirate theme- anything you can imagine and sketch out for yourself. If you’re trimming down the tree consider recycling some of those limbs and branches into the treehouse’s woodwork- perhaps constructing a rustic railing that overlooks the backyard lawns of your suburban neighbors.
