To get from my (not yet existing) new balcony section down into the garden, I would like to "wind" a staircase downwards. The matter is not easy to describe... The newly added new part (approx. 1.80 meters wide and 5 meters long) will be made of steel and will be embedded on one side into an existing wall. The other side needs a pillar (or rather 2 support points). On my "roughly sketched" drawings, you might be able to imagine how it is intended. [ATTACH alt="TreppeSüdansicht.jpg" type="full"]56413[/ATTACH] The reason for my question is: The normally 3/4 (about 270°) wound staircase is supposed to be longer in one direction than in the other, so oval. The reason for this is that the exit at the bottom should be at a certain spot and the exit at the top is also fixed. The "point" around which the staircase is supposed to wind is about 40 cm wide. Seen from above here. (the round circle is the supporting pillar, a second one would be in the center of the second wound part (at the bottom of the drawing)). [ATTACH alt="TreppeAufsicht.jpg" type="full"]56412[/ATTACH] For completeness, I am also including the third drawing from the other side here. The rectangular "block" on which the pillar stands is a "concrete box" (in which I can store garden tools) and at the same time the foundation for the main part of the balcony's weight. [ATTACH alt="TreppeWestAnsicht.jpg" type="full"]56414[/ATTACH] So far, I have not been able to find anything on the internet about "oval spiral staircases". No wonder, probably not very common. But I simply enjoy this idea. Staircases can be "something special" if done nicely. A few examples that I like: (just for fun)

Interesting, but unfortunately I can't find the question... ;)

my question is: Does anyone know more about this specific staircase construction, or a source where I can find information about it? I wouldn’t even know exactly what to call the staircase construction. Oval spiral staircase? or what?

How is your plan to be understood? Do you want to tackle it yourself or hire someone? Actually, it doesn't matter, but my first point of contact would be a stair builder. I wouldn't overlook this experience for such a special project. If self-construction is desired, you can get him involved in advance for planning services.

Yes, that's true.
Basically, it is "these experiences" for which I am looking for a verifiable source.
A friend of mine is a blacksmith and locksmith. He - I hope - will take on the construction and implement it with my help.

I also know a very lively and communicative stair builder (who already installed one in my house), but these are Corona times and I currently avoid getting too close to anyone if it can be avoided.
