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 treehouse 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 a treehouse 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 the treehouse 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 on line 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.
