Stairs - Are the stair dimensions 2.00x2.00m okay?

The picture shows a platform staircase. In the floor plan, a small 1/2 wind staircase is drawn. According to Treppe 1x1, a depth of about 2.80m would be needed. I don't see the additional 80cm anywhere without reducing all the other rooms (especially upstairs).

Oh dear. Too bad, it could have been. Thanks for the info.

I would still advise you to reconsider your future staircase. 2mx2m would be much too small for me. In the end, you might only get a walking width of 75-80cm? I would inquire more precisely about what the staircase builder says and can do. Especially see it, if possible! Taking away 40cm from the kitchen and the study might hurt less than having this narrow staircase forever?

40 cm less kitchen would not bother me, however the room upstairs will be the 2nd children's room. Therefore, I wouldn't want to take away that one square meter from the room now. If it becomes a standard steel/wood construction, the perceived width without a handrail on the wall should rather be 95 cm per side, right?

For us, the rough construction dimension was 2.26 cm in width. Unfortunately, I do not have the finished step dimension and the width of the stairwell [Treppenauge] at hand, but maybe at least a few CM could be forgiven.

By the way: personally (very subjective!) I prefer walking on such a staircase compared to a landing staircase—I just don’t quite like the interruption of the walking rhythm by the landing and the deliberate change of direction... but of course everyone has to try it for themselves.

Edit: don’t forget [Treppenauge] or start thinking now about how it should look later, where/how the railing will be attached (in the eye or mounted on the steps?) and what will then additionally be lost because of the handrail!

If it’s a standard steel/wood construction, the perceived width without the handrail on the wall should be about 95cm per side, right?

Or not. Then the handrail will scrape against the next supports.

Ever hoisted furniture upwards on a perceived width? I prefer real widths, not perceived ones [emoji23]
