Now we are working on the roof and then we will talk through the walls and windows after that.
How to build a treehouse roof around a tree.
Add spacers between the beams and the tree to.
The top set of beams will be the floor height of your treehouse.
Don t constrict branches with rope straps or wire.
Don t restrict tree growth.
Try to to drill the pilot holes as straight and level as possible.
On each corner install an angled 2 x 8 down the tree directly below the main supports.
Once you finish one corner move on to the corner opposite of it and work on that one.
Top off the tree just below the roof line and build a solid roof above.
Build the diy treehouse in mid summer.
Minimizing tree damage for diy treehouse.
Divide that number by pi 3 14 to get the diameter.
Get it perfectly horizontal with the help of a level and nail the other end to the other tree.
This can strangle the tree.
A good roof protects the whole of the treehouse beneath it.
2x4 inch boards work well for this and you will end up with a square to work with.
For reference we have finished the base and frame of the treehouse as well as the floor and stairs.
Aim for a slope of at least 30 but preferably 45 or more.
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.
I have seen a treehouse built in four cedars designed this way and it works remarkably well however it is not practical for most applications.
If your design calls for a flat roof try to introduce even a small slope of 3 5 so water cannot sit there.
Build the perimeter of the frame using 2 x 6 or 2 x 8 cuts of lumber.
Now it s time to build the platform atop the supports.
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.
Rails sides and a roof complete the treehouse.
For a standard 8 x8 treehouse choose a tree with a trunk at least 12 in diameter.
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.
The first is a bit dramatic.
Making a treehouse roof.
Find a corner that isn t square and create braces to run at the top corner of the wall.
A properly sloped or pitched roof is much superior.
Add the floor joist perpendicular the main supports.
The second solution is to build a wall vapor barrier around the trunk on the inside of the treehouse.
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.
Leave gaps around the tree.
