To access my (not yet built) new balcony section from the garden, I want to create a spiral staircase leading down.
This is not easy to describe...
The newly added section (approximately 1.80 meters (5 feet 11 inches) wide and 5 meters (16 feet 5 inches) long) will be made of steel and connected on one side to an existing wall. The other side will need a pillar (or two support points).
Maybe my rough sketches give an idea of the concept.
The reason for my question is:
The staircase, usually winding 3/4 of a turn (about 270°), is intended to be longer in one direction than the other — in other words, oval-shaped. This is because the exit point at the bottom needs to be at a specific location, as does the exit at the top.
The "pivot point" around which the staircase spirals is about 40 centimeters (16 inches) wide.
Here it is shown from above (the circular shape marks the supporting pillar; a second pillar would be in the center of the second spiral section, shown at the bottom of the drawing).
For completeness, I’m also sharing the third drawing from the other side.
The rectangular "block" supporting the pillar is a concrete box (which I can use to store garden tools) and also serves as the foundation for most of the balcony’s weight.
So far, I haven’t found anything online about oval spiral stairs. No surprise since they are probably rare. But I simply enjoy this idea.
Stairs can be “something special” if they are well designed.
A few examples I like (just for fun):

Interesting, but unfortunately I can't find the question... 😉
How should your project be understood? Do you want to tackle it yourself or hire someone?
It doesn’t really matter, but my first point of contact would be a stair builder.
I wouldn’t overlook this experience for such a specialized project.
If you want to build it yourself, you could involve them early on for planning services.

A friend of mine is a blacksmith and metalworker. He – hopefully – will take on the construction and carry it out with my help.
I also know a very lively and communicative stair builder (who has already installed one in my house), but these are COVID times, and I am currently avoiding close contact with anyone if it can be avoided.
