Hello everyone,

In a few days, we have the staircase selection appointment. On the stair builder’s website, there are layout proposals for the staircase. We have allocated 3.04 meters by 2.25 meters (10 feet by 7 feet) for the staircase area. You can find the house floor plan here in the forum at the following link.

Floor plan #44

The stair supplier suggests 16 steps for the space online. Here in the forum, 15 steps are mentioned. So I wanted to ask for your opinion again: 15 or 16 steps?

Maybe someone has a similar amount of space for their staircase in their house with either 15 or 16 steps.

Well, first you need to know what can be changed and if any changes are possible at all. So, precise measurements, then calculations and drawings. And this should be done by someone who knows exactly what needs to be done with stairs. Because that is not a trivial task.

The building permit generally applies to the building described in the application's technical drawings. The material is not important to the building authority, but I would not recommend deviating from the specified number and dimensions of the risers.

Well, I think that is a bit excessive for a single-family house. This is not a public concert hall where people are rushing up and down the stairs. The authority is hardly, if at all, concerned if you deviate by 10cm (4 inches) here.

If I understand your floor plan correctly, adding another step would hardly be an issue if you reverse the direction of the staircase. Is that still possible?

Yes, reversing the direction of travel is still possible.

Can’t I just add one more step before the landing? It’s about 12cm (5 inches) that the step would protrude, and that wouldn’t bother me much. The stairwell measures at least 3.04m x 2.25m (10 ft x 7 ft 5 in). We won’t have an issue with headroom since we maintain at least 2m (6 ft 7 in). See also the picture.

Many things often do not seem to be bothersome at first.
However, this raised step will become a tripping hazard in the hallway, which could be dangerous for other residents in the house as well as for you.

At the bottom of the stairs on the ground floor, the step would be very inconvenient. As Yvonne already mentioned, it would become a tripping hazard. Additionally, it narrows the hallway in front of the double door.
On the upper floor, however, it fits in without any issues:

It may involve some effort since a part of the ceiling would have to be cut out. But it’s better to use the saw once now than to keep stumbling over the step later on.

PS: Please don’t post such small sections all the time. You always need to see the surroundings to properly assess the situation.
