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.

But I simply enjoy this idea. Staircases can be "something special" if done nicely. A few examples that I like: (just for fun)
