Do you have trees in your backyard? If so, you’ve probably already given some thought to the subject of today’s Wonder of the Day. Maybe you’ve already built one! What are we talking about? A tree house, of course!

Tree houses — sometimes called tree forts — are platforms or small buildings built around or within the trunk and branches of large trees. Although some tree houses can be very complex and used as homes, most tree houses are far simpler structures used as places for kids to play.

Tree houses in some areas of the world can be homes that are very practical. For example, in some parts of the tropics, tree houses are built in trees or supported by stilts. This keeps the tree house above the ground, which protects it from floods and animals hunting for food.

If you want a fun place to play in your backyard, though, you don’t need stilts or a tree house designed by an architect. In fact, you might have all you need in your garage or basement. That’s right! Many tree houses are made with all sorts of recycled materials.

You’re probably going to need some wood. A large piece of plywood to use as a platform or floor is often necessary. You might also use wood to build walls. Some people recycle old windows to use for their tree houses.

You’ll also need some simple tools, like hammers and screwdrivers. You can probably find a lot of the fasteners you need, such as nails, screws and brackets, around the house or in the garage.

If you ask your mom, she might have some old fabric you can use to make curtains or doorways for your tree house. She might also be able to help you find old pillows and blankets you can use to make your new hideout cozy!

While playing in a tree house can be lots of fun, it’s even more fun to build a tree house with the help of a friend or family member. The time you spend planning your tree house, looking for recycled materials and building the structure together is time well spent that you won’t soon forget!

    • We think you are a SUPER creative Wonder Friend, Carlos! Maybe you could build an AWESOME fort in your backyard and use your imagination to pretend you are in a tree house that’s atop a tree in a wild jungle or a quiet forest! We think that sounds like FUN, FUN, FUN! :-)

    • That’s a GREAT question, Kurt! We’re not sure about that one, so we’ll both have to go on a Wonder quest to see if we can find the answer to your WONDER! Thanks for letting us know you thought this Wonder was awesome…we really appreciate hearing that! :-)

  2. The best tree house is in Alnwick Gardens, it’s massive and even has a restaurant in it! I’ve been in it before, too.

  4. The story was cool because it tells you where you should build a tree house, and what you need to build one. I also wish I had my on tree house it would be so cool.

    • We agree, Jada! It would be WONDERful if everyone could have their own tree house! Yet, even if you can’t have a tree house… maybe you could try building a fort, or a club house. You can even build a fort out of blankets inside your home. All you have to do is use your imagination! Enjoy, Wonder Friend! :-)

    • Awesome, Jake! How cool that you have your own tree house! Did you build it yourself? Thanks for sharing! :-)

  5. I have sooo many big trees in my backyard but my parents wont let us get a treehouse! It would be so fun to play in in the summer. :(

    • Hi, Abby! Maybe you can go visit a big tree house one day. You could read a good book in a nice, shady spot, under the big trees in your backyard. Thanks for visiting WONDERopolis! :)

  • If you could build any kind of tree house, what would it look like? Put pencil to paper and come up with a blueprint for your tree house! What will it look like? Will it have one big room or multiple smaller rooms? How will you get up to it? Will there be a trap door? Windows? Be as wildly creative as you want to be. Forget about practical constraints. This fun exercise is all about letting your imagination run wild. What kind of tree house would you create if you could build it in any kind of tree anywhere in the world?
  • Up for a challenge? Get outside and make your own tree house! If you have trees in your backyard, you may be able to build a simple tree house out of scrap pieces of material you may have around the house or in the garage. Of course, before starting on such an ambitious project, you’re going to need to get approval and help from an adult. You’ll also need to search for some recycled materials you can use to build your tree house. If you don’t have the right kind of trees in your backyard, ask a friend or family member if you can build a tree house in their backyard. You never know when a friend or relative might have the perfect tree just waiting to be turned into a fantastic play place. Have fun creating what might become a clubhouse for your entire neighborhood!
