Stable and reliable anchoring is the first requirement for a tree house. Static requirements must be created in a dynamic environment. The tree continues to grow and the weather has a permanent effect. It is also important that the implementation is as gentle as possible, which can be achieved above all with special accessories.
Three anchoring options
For a tree house in the garden, it is inevitable to create firmly anchored connections between the tree and the timber. The only exception is a tree house on stilts, which as a free-standing construction is only connected to the ground by means of a foundation.

There are several ways to create anchor points to attach a tree house:
- Screws in and through the tree
- Cuffs and bells that are placed around branches and trunk
- Steel ropes that can be hung over branches
The construction of the platform usually serves as the basis for building a tree house. It is placed on forks and branches and stabilized. When planning the tree house, the following fastening and anchoring criteria must be taken into account:
- The weight load must be fixed and secured so that it can be removed
- Possible tilting of the platform and all components must be prevented
- Strong weather influences such as driving rain and strong winds must be withstood
- The usage load from several people (approx. 50 kg / head) must be held
- The anchoring must remain stable despite the tree growth
- As few injuries as possible to branches and trunk should be caused
Special screws are the best choice
Special manufacturers have developed tree house screws that adapt to the natural growth of trees as anchors. They are driven into or through the trunk. The tree "recognizes" this foreign body as an injury and reacts. As it grows, it integrates this "artificial" branch.
The screw grows in and the tree places a protective bead around the exit points. This integration is essential to prevent moisture and moisture from penetrating the heartwood of the trunk and branches. Internal putrefaction would be the inevitable consequence.
When anchoring with cuffs, clamps and ropes, one must always think of the "constricting" of the growing tree. You shouldn't skimp on expensive but adjustable accessories.Tips & Tricks Once you have found a suitably grown tree and plan carefully according to building physics rules, four anchors on branches and / or trunk are sufficient in most cases.
