Add spacers between the beams and the tree to.
How to build a treehouse roof around a tree.
The top set of beams will be the floor height of your treehouse.
This can strangle the tree.
For reference we have finished the base and frame of the treehouse as well as the floor and stairs.
Making a treehouse roof.
Get a strip of light wood and nail one end to one of your trees at a height about 1 ft lower than you want the floor of your treehouse to save a future concussion it should also be at least 1 ft higher than your head.
Aim for a slope of at least 30 but preferably 45 or more.
Once you finish one corner move on to the corner opposite of it and work on that one.
Find a corner that isn t square and create braces to run at the top corner of the wall.
Build the diy treehouse in mid summer.
Add the floor joist perpendicular the main supports.
Leave gaps around the tree.
Next install the perimeter beams to the top set o beams and square them up using the 3 4 5 rule.
A properly sloped or pitched roof is much superior.
Now we are working on the roof and then we will talk through the walls and windows after that.
To calculate your tree s diameter measure its circumference by wrapping a string or measuring tape around the trunk at the point where you want the treehouse to sit.
Build the perimeter of the frame using 2 x 6 or 2 x 8 cuts of lumber.
To accommodate tree movement and growth allow gaps around any branches or trunks that penetrate the tree house.
Lag two sets of beams to the tree using a 3 4 diameter x 10 lag screw.
Try to to drill the pilot holes as straight and level as possible.
Rails sides and a roof complete the treehouse.
Don t restrict tree growth.
Get it perfectly horizontal with the help of a level and nail the other end to the other tree.
On each corner install an angled 2 x 8 down the tree directly below the main supports.
If your design calls for a flat roof try to introduce even a small slope of 3 5 so water cannot sit there.
2x4 inch boards work well for this and you will end up with a square to work with.
Minimizing tree damage for diy treehouse.
If you get particularly harsh winters a steep pitch is critical to avoid a build up of snow which could easily spell disaster for a treehouse of limited support.
Divide that number by pi 3 14 to get the diameter.
The heavy spring flow of sap will have slowed greatly but the tree will still have time to heal before winter.
Add joists on 16 inch centers and build the floor with deck boards or 3 4 inch plywood.
Don t constrict branches with rope straps or wire.
