How to Build a Treehouse- Phase One: Picking & Prepping the Trees

So the daughter turned 7.  And it seems like all of a sudden she started talking about a tree house.  Not sure where she got it from.  We may have seen one or maybe a friend at school mentioned theirs.  For all I know she saw it on tv.  But no matter, cause she planted the seed in my brain.  I had a club house as a kid, built around trees and within trees but nothing actually in a tree.  So I wanted her to have an actual Tree House.  Now, I do a lot of real estate so I know about houses.  And I’ve done enough work on my rentals to know a lot about construction.  Heck I’ve even done some framing.  So I know I can do it.  Just have to apply what I know to a slightly different setting.

The first step was a lot of research.  I looked at tree houses on the internet, and found a few sites that were helpful.  I read some books of plans, checked out Youtube, even looked on Pinterest (which was mostly crazy dream homes- doesn’t anyone post normal tree houses on there? I mean besides me, cause I am gonna).  Most of the plans I saw used one tree with a deck built around it.  Unfortunately I don’t have one tree in my yard that is thick enough to support the weight, much less having the right placement of branches.  But I do have 2 trees so I looked for plans for 2 trees.  I found a very helpful link on Instructables which had a plan for 3 trees that I slightly modified.  Then I took some notes, drew some basic sketches, and got started.

Height is an issue- you want it to be high enough to be fun but not high enough so that you can’t actually do any work on it.  I chose around 8 feet up- just high enough for me to still be able to reach it.  I measured the distance between the trees and got two 2 by 10 treated decking boards and some long 3/4 inch lag bolts.  Because to support the weigh of the house, I had to place it between the two trees.

I was doing this myself (well not really- I had my 7 year old daughter helping me, for what it’s worth) , so I used ropes to pull the boards into place and tied them off.  Also I used old 2 by 4’s to add support underneath while I drilled the pilot holes in the tree.  The tree has to be drilled.  But I used lag bolts that do not go all the way through the tree and when I was done I left the whole thing alone for a few weeks so the tree could heal.  Killing the trees would not be good for supporting a tree house.

It was also important to make sure the boards were level both ways- across the top and level with each other.  So that the decking would be level as well.  Measure twice, cut once is rule number one but Rule Number 2 should be Keep it Level- check it constantly.

That’s Phase One.  That was the easy part, trust me.  Compared to Phase Two, that is.

On to Phase Two- The Base!
