The architect's draft is ready so far, a half-turned staircase is planned here.
You can make everything worse while trying to improve it.
We don’t really like the spiral one, so I started looking for alternatives that we like.
That’s legitimate so far, but unfortunately ...
It turned out that a staircase with a landing and straight steps would be nice. The example above is my attempt to combine straight steps and a landing with comfortable dimensions without taking up too much space.
... it didn’t come out as it should have: the staircase in the kindly copied image by RobsonMKK you go “Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav, Gustav” (and that was “only” upwards; downwards the limp rhythm hits even harder). That is not stair climbing, that is sack hopping. That’s why no one who is musically talented enough to be not only a civil engineer but also an architect would come up with such a crazy idea.
Moreover, I wouldn’t want to go below 1m raw construction width for any staircase, and your step front edges at the changes of direction are incorrect.
We are already in the approval planning phase,
That could be the last minute rescue
(I hopefully understand correctly that a worsened staircase will fail at the given ceiling opening)
