I will try to explain to you with pictures and words how I went about building our treehouse. I will not give specific measurements because the truth is that with treehouses you need to make the treehouse to fit the detentions of your trees and surrounding area. My hope is that this post can give you some food for thought and maybe the basis of a project that you could do for your kids in your backyard. When I started this project I didn't know what the final treehouse would look like. I did one step at a time and then figured out the next one as I went. That is the joy of DIY projects, watching how they grow and develop and then standing back and admiring the results of what you made yourself.
DIY Playhouse to see how I make the floor base and many of the steps that follow. I used the same procedures to make both of these projects. The base for my treehouse is 10ft x 10ft. I built this on the ground where it is flat and then begged for lots of help to pull and push it up onto the platform. Whew, what a job.
here) and got a nice big one, I think it is a semi tire, and it is very heavy. I plan on doing a post in the future on how I hung this swing. To attach it to the tree house I used an eye bolt that I put through both the decking board floor and the 2x4 that made up the framing of the front of the tree house above.
site I found was helpful. I then hauled the rafters up to the house and marked where they would rest on the side walls. I then took them back down to the ground and cut out a notch so they would rest nicely on the walls. I cut out one and then used it a a template for the rest so they were all the same. I did leave a little overhang at the end of the rafters so the roofing would extend beyond the side walls of the treehouse.
So this is the way the treehouse stood for the winter. Occasionally the kids would climb up there but I knew that the next phase of the treehouse build had to be making a better, safer way to get into the treehouse.
I had decided on using a stairway/ladder combination. With young kids a stairway is he easiest way of getting up to the treehouse but a stairway that goes up 10ft is next to impossible to find and would take up a lot of space. So a combination of stair and ladder seemed to be the answer.
To start this project I first dug holes for 2 more telephone poles that I placed in a triangle with the original pole used for the main treehouse. I placed these poles so they were all 5 feet apart keeping the line between the two poles closest to the treehouse parallel to the treehouse floor base.
I then put up more 2x6 boards with lag bolts connecting the 3 poles in the same fashion as I did for the main tree house. I had bought my stairway prior so I knew what height they would reach to and I placed the 2x6 at the appropriate height to accommodate the stairs. I then attached the stair, making sure to use blocks as a firm landing at the bottom.
Once again I got some decking boards and used these on the stairs and also the triangle landing. I did have to attach some bracing boards inside the landing triangle so there was more support for the decking boards. Tip, I found it easiest to cut the decking boards to the longest length needed to cover that part of the triangle base and then later take a circular saw along the edge to cut the boards to the angle of the triangle.
I was going to describe to you how I found these angles and was having difficulty doing this. I decided that a picture is truly worth a thousand words. Finding the angle was as simple as taking the side of my ladder out to the treehouse, setting it at the angle I wanted it, then using a scrap piece of wood drawing a line that would be parallel to the floor. I repeated this same procedure for the top angle. I did have to take into account the amount of length this would cut off of my boards. Simple enough.
I did secure the ladder so it would not move and be safe for the kids.
As you can see The tree house is simple with no front door or paint. So far the inside is mostly bare but I sure that will change over time.
To solve this I decided to rake the play area thoroughly and then ordered a truck load of sand. I took a lot of work to move that much sand around by shovel and wheelbarrow, I have the blisters to prove it but I am in love with the results. The sand instantly transformed the treehouse area into a playground where the kids love to spend their time and I can feel ok about their lack of shoes.
