Spiral staircases (large radius without central upright) and spiral staircases (small radius attached to central upright) are complex custom-made products from carpentry, joinery or carpenter’s workshops that require a lot of expertise.
Spiral staircases made from “one cast” are either bent or assembled from numerous individual parts.
The stair construction should be as self-sufficient as possible from the tree and only be supported by the tree at a few points (with wooden struts).
We advise against the method of screwing each individual step into the living tree!
- this technique is no longer professional: “professional tree house construction” means as few injuries as possible. This is the general opinion of professional treehouse builders worldwide (see “World Treehouse Conference”).
- Screwing step by step one by one into the tree is what we did as ignorant children
- many small injuries and many individual pressure points mean stress for the tree
- Each of these steps can deform individually, making stair climbing unpleasant and dangerous.
For do-it-yourselfers, the construction of a spiral staircase is suitable – as always, you can find instructions on YouTube.
