ᐅ Is a staircase layout with two quarter turns plus a landing possible within a maximum area of 2.4 by 2.4 meters?

Hello everyone,

We have planned a quarter-turn staircase. It needs to cover a height of 2.95 m (9.68 ft). Space requirement: 1.8 m by 2 m (5.9 ft by 6.6 ft).

This seems to me like a code-compliant main staircase with sufficient dimensions. Any opinions?

However, we would prefer a staircase with landings. To make better use of the space, I would like to create two 1/4 turns with landings at each corner of the staircase. How much space do we need for this? Unfortunately, I can’t find any calculator for this.

Is it generally mandatory to follow code-compliant staircase dimensions, or is it possible to deviate within certain limits?

I would appreciate any suggestions!

Best regards,

I think the stairwell space is wasted,

Your stair dimensions suggest a spiral staircase, meaning that if the stairwell space were narrower, only the unusable part of the steps would become wider, and the central line would shift accordingly. This wouldn’t be beneficial. Secondly, it wouldn’t be an advantage since increasing the width tends to shorten the overall proportion. For straight stairs, I would agree with you, but in this case, I believe that having a larger stairwell space most likely creates a greater sense of openness.

Good point, I hadn’t considered that. So, the narrower opening could be useful only for transporting items upstairs, right?

In this regard, it is probably only marginally beneficial, precisely because the advantage is near the spiral.

Depending on the items that need to be moved upstairs, having a large stairwell opening can sometimes be quite practical. For example, if the item is rather narrow but long, it can be easily pulled up through the stairwell opening. However, this situation does not occur very often.

Thanks for the advice, I think we will leave the floor plan as it is then.
