Floor plan approx. 170 m² single-family house, without basement with carport

…. You only fall halfway when you fall.

That makes sense :D

I guess people worry too much about that. Children are flexibility personified.

Yes, probably. You hear so many horror stories that you probably always tend to be overly cautious... Although I definitely think it’s important to consider how the house “works” for the children.

And then only with a handrail? Look, the “harp” or vertical balusters on the railing have the advantage that the child can grab and secure themselves anywhere at any height.

We definitely planned to have a railing along the stairwell opening. But that would work with both stair types. Aside from the safety aspect: What are the advantages of the landing staircase? Presumably, it makes the most sense to choose the stair type purely based on the floor plan, right?

Regarding the architect’s floor plan: We don’t find the floor plan bad at all either. For example, we like the following: - Storage room space by the garage - Lateral positioning of the stairs - More spacious bedroom But for us, these are not must-haves, and Katja’s design feels much more “spacious.” The family bathroom is larger and also has space for a walk-in shower. The rooms are more sensibly arranged according to the cardinal directions, and the southern sun can be used effectively. The contiguous garden area to the north is also longer. Next, we will show Katja’s design to our architect and ask how feasible it is and what it would mean cost-wise exactly.

What are the advantages of the landing staircase?

well, I know them from commercial and residential construction... they bridge a higher ceiling and offer storage/resting possibilities during transport. Why people are so fond of them, I don't know. It's just something special with a special price. And since higher ceilings are modern, maybe they are necessary for safety?

Presumably, it makes the most sense to choose the stair shape purely based on the floor plan, or

I would do the same. Personally, I would not insist on something that could be swapped out in practice.

Katja’s design feels much more "spacious."

It’s the feeling that matters! And if it’s good: perfect! : did you think about the piano?

I would do it that way too. Personally, I wouldn't hold on to something that would be interchangeable in practice.

In terms of dimensions, the double-spiral staircase is the narrowest or most space-saving solution, right?

: have you thought about the piano?

We have already thought about the piano a bit. We considered either putting up a small partition wall between the dining and living room to place the piano against. Or on the left exterior wall. Normally, a piano shouldn’t be placed against an exterior wall, but our house provider said that this is not an issue with wooden houses at all. Of course, we are open to other suggestions :).

I think it is important in any case to consider how the house "functions" for the children.

It will work out - as already said: people adapt from a young age to what they find. Since they grow up with it.

We don't think the floor plan is bad at all.

I don't find the bathroom family-friendly now, as it is too small. The children's rooms face north, and if a somewhat smaller staircase is installed there, you could even fit the closet behind the door. And you have a utility room upstairs with Katja. I would put a large wardrobe there for the bulky laundry… basically a half dressing room ;)

Sure, but you can also just drive to a staircase studio and experience the thing. If I had the choice, I would always prefer the landing staircase over the half-turned one.

Next, we will show our architect Katja's design and ask how feasible it is and what it would cost exactly.

Ask especially about the structural feasibility.

: did you think about the piano?

Piano as well?! Then probably a terrace door would have to give way for the living area and the piano would go on the west side.

What speaks against something like this?

Sorry, I'm really not gifted in drawing but I hope you understand the idea.
We don't have a living room set but a sofa with a chaise lounge. It is 3.12 meters wide and the chaise lounge is 1.65 meters long.
We would like to mount the TV on the outside wall anyway. Currently, we have a window directly opposite the TV. That is terrible in terms of reflections.
And I think we could live well with a simple glass door as a passage instead of a double-leaf door.
You would just have to take a closer look to see if you can still easily get out to the terrace or if the partition wall with the piano just gets in the way...
The piano is 1.47 x 0.55 meters.
Or could you just put the window above the piano? The piano is one meter high. Window sill height at 1.70 meters? Doable or nonsense?
I don't know if the entered dimensions on the floor plan are correct - I measured with a program.
