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 played around with it again last night, and this is what I came up with, which I basically like and which would also fit in terms of dimensions:

16
18.44/26, three flights:
1. 5 steps, then the first landing as step 6,
2. 2 steps, then the second landing as step 9
3. 6 steps, then the upper floor as step 16

Do you think this could work? I really want to check whether I can manage a straight staircase after all before I fully commit to a spiral staircase.

In your headline, you mention 2.4 x 2.4. This is not enough space for a landing staircase with a standard ceiling height, and even then, it would be very tight (practically no proper landing). So it’s more suitable for a typical two-quarter turn staircase.

A landing requires at least the space of twice the width of the stairs.

Since I can’t open your link and can’t imagine what type of staircase you mean—logically, landings would be excluded and your measurements don’t fit the available space—it would be helpful to upload a picture or drawing here. Did you overlook my link?

Best regards in brief

No, I didn’t ignore your link. The staircase has a rough dimension of 2.42m x 2.77m (7 ft 11 in x 9 ft 1 in), so it has grown significantly on the upper floor, but the width has remained roughly the same. This should still be within the minimum dimensions specified in your link.

I’ll have to check later today how I can upload a picture here.

/Edit: Thanks for uploading it @RobsonMKK

What kind of staircase do you want?
Wood, cantilevered? Steel stringer or concrete?
Keep in mind that a rough opening dimension does not represent the final measurement. Additionally, a freestanding wooden or steel stringer staircase requires installation space, and the stringers do not necessarily have to be placed directly against the wall.

Are you still in the initial personal planning phase?

We would like a concrete staircase. The treads will be covered with wood (parquet, as used on the floor), while the visible front side should remain exposed concrete.

The architect’s design is mostly finalized and includes a half-turn staircase. However, we are not completely happy with the spiral design, so I started looking for alternatives that we like better. It turns out that a staircase with a landing and straight steps would be nice. The example above is my attempt to fit straight steps and a landing with comfortable dimensions into a relatively small space.

We are already in the building permit / planning permission phase, and the staircase is really the last item we are not fully satisfied with.

Is there anything against having such a concrete staircase with these dimensions? Is it a problem that there are more steps at the top than planned at the bottom? Upstairs we simply have more length available than on the ground floor.
