The tree used for our tree house must be healthy, stable and have branches at least 10 cm thick in order to be able to reliably support the structure. If you are unsure, get tips from a garden and tree specialist and, if in doubt, consider additional support methods.

Now it’s time for the actual construction instructions. If you build your tree house yourself, It all depends on the tree, the wood used and a good treehouse base. We therefore focused on safety for the treehouse floor and used 10×10 cm squared timber.

First saw two 1.20 m long pieces from a squared timber with a length of 4.40 m. Now place the two shorter squared timbers flat on the floor, place the two longer ones on top at both ends and screw two 20 mm hexagon head screws with washers through the frame at each support point.

To mount the frame in the tree, find one The most suitable, stable location with thick branches and trunks out of. It is particularly important that the Support surface is in balance. A spirit level helps here. A screw should be able to be screwed into the tree wood at at least one point on each side. The more screws between the tree and the frame, the more stable and better!

Before nailing you must give the frame some structure: To do this, a 100 cm long 6 x 6 cm squared timber is screwed to the front and back of the tree house (you should define these now at the latest) at the top end of the posts Frame supports front and rear.

Now it’s time to nail: Nail six of the 120 x 20 cm long boards on each side with at least eight nails per board, four on each side. Six of the 100 x 20 cm boards are nailed to the back of the tree house, also with 4 nails per side. You can leave the front “open” to Getting into the treehouse is easyor you plan with a little more wood, put some boards on the front and leave an area free in your desired dimensions.

Then nail the remaining five 120 x 20 cm long boards onto the roof structure. About that To permanently seal the roof, use the cardboard nails to nail the roofing felt with an overhang of around 10 cm on all sides around the walls. At the front, simply pull the roofing felt inwards.
