First floor plan attempt for terraced house on a small plot

If one knew the heights, one could exactly calculate what is possible. It pains me a little if the client cannot realize her desired staircase. Perhaps one can still sneak in a step somewhere in your design.

If the details of the staircase in post #43 are correct, then the floor height is 2.82m (15x18.8).

... Katja, had posted this stair distribution from his provider: Landing width of 101 cm plus probably 4 cm railing at the top end, the stairwell railing subtracts from the 101 cm. I would also like to keep the landing width. However, if you want to achieve more than 23 cm tread depth, every additional cm of tread depth increases the 270 cm by 7 cm. I had heard the floor height was 285 or 290 cm, so probably about 254 cm clear room height.

Let's see:

7 steps up, then a landing, 7 steps down, with the last step being the exit step - correct?

Then we would have a sporty rise of 19 (285/15, that can be done) and a narrow tread width of 25 (there will be an additional 2cm overhang per step for big feet):
7x25 = 175 + 100 landing = 275cm up
100 landing + 6x25 = 250 + exit (hallway) down

As far as I remember, the 275cm landing stairs are also typical for small houses. Or did I miscalculate? Somewhere a no-go?
In any case, I would rather go up 19cm than have only 23cm tread. What do you think?

100 landing plus railing or the walking width decreases. In Yvonne's plan one could actually try the landing stairs, however it becomes narrow at the top if you want to orient yourself on "my" version there. Although my planning still prefers the house width of 820 cm. There would still be a bit of space on the left since Yvonne has already planned with 850 cm, if I am not mistaken.

90s running width must be enough when you include the railing. It’s roughly like a door then. That’s doable, I think. At the top exit we save a step anyway if No. 7 is the hallway. And I wouldn’t give up the 30cm at 8.50 anyway.
