ᐅ Installation shaft and chimney flue combined in one?

The length of the staircase is 3.60 meters (12 feet), with 15 steps. Too short? This measurement was taken from the forum:

Do you really want a ceiling height of only 2.8 meters (9 feet 2 inches)? If you consider 2.6 meters (8 feet 6 inches) room height plus 20 cm (8 inches) for the ceiling and another 20 cm (8 inches) for insulation, screed, and floor covering, you already reach a floor-to-floor height of 3 meters (10 feet). A higher floor-to-floor height generally requires a longer staircase, even if the angle remains the same. The angle of this short staircase is already at the upper limit. I find this too steep, hence the comment about a ladder-like staircase. A gentler slope obviously requires a longer staircase.

If you read my first post, the detailed question arose because we are considering planning the bathroom above the living room, so we don't have to give up the home office room and the children's rooms can be located on the west side at the same time.

But why focus on a detail question if the basic concept is not sound?
You yourself say this is a process. But you start with fundamentals—details come later.
You are planning with a poor design; just look at the bathrooms. Setting aside that it’s best to avoid water pipes running above living areas (which already indicates poor planning), the other bathroom is almost unusable with your wall right in the middle of the narrow room.
The same applies to a chimney placed at the eaves. Then you have a pitched roof and end up with a problematic staircase.
Your staircase... the small “emergency staircase” for small houses...
It’s good that you’re asking about a detail that, in your view, might be a reason to make changes. But there are already so many fundamental problems. On the ground floor: guest room—almost impossible to furnish. There was also a bathroom connected to the bedroom on the east side, about 2 meters (6.6 feet) in size—unusable. If basics like that don’t work, then there’s no point discussing a fireplace or chimney shaft.

If that’s not the case, then we will start thinking about a different plan in good time.

But if it does work and we get positive feedback here, why not use the forum?

Because you continue despite so many clear planning mistakes.

BauFamily schrieb:

The whole planning is a process, and along the way to the final floor plan, basic questions (such as whether the bathroom should be above the living room or about the chimney shaft) are part of it,

Later. A process does not start at the end.

I simply didn’t want to present what we see as a “final” floor plan (before going to the architect) to the community yet. That’s why I wanted to “feel my way” through this thread. But since we’re at it, here is the ground floor:

Nothing here is final yet. What you have is unattractive and will not be final. Final means right before the building permit/planning permission stage, which usually involves multiple revisions with the architect. Playing around is fine, but you either play the beginner version and then let the professional handle it, or you plan alongside the professional. You can also rely on crowd knowledge if the professional is not competent.
A floor plan discussion on this forum lasts about six hours. After that, it’s repetition or small talk—and the interest fades.
At this point, the only real question is whether you are budgeting about 650,000 just for the house.

If you calculate 2.6m (8 feet 6 inches) room height plus 20cm (8 inches) for the ceiling structure and another 20cm (8 inches) for insulation, screed, and flooring, you’re already at about 3m (10 feet) floor-to-floor height. A higher floor-to-floor height generally requires a longer staircase, even if you keep the same angle. The angle of the short staircase is already at the upper limit. To me, that is too steep, which is why I mentioned the ladder-like design. A shallower staircase of course requires more length again.

Thank you, I wasn’t aware of that. I assumed that a floor-to-floor height of 2.80 meters (9 feet 2 inches) would be sufficient, along with the staircase dimensions, as I found in this forum. Am I correct in assuming that for a taller floor-to-floor height, I should plan for about 4 meters (13 feet) more staircase length to avoid having a ladder-like staircase?

You’re planning with a poor draft; just look at the bathrooms. Aside from the fact that, ideally, water pipes should be avoided running above living areas (it’s simply bad planning if they do), the other bathroom is basically unusable because of your wall right in the narrow space.
The same applies to a chimney placed at the eaves. Then you go for a gable roof and end up with a headache-inducing staircase.

It’s good that you ask about the details, which to you might be the only reason to change something. But there are so many fundamental problems already. On the ground floor: guest room is almost impossible to furnish. Somewhere there’s a bathroom next to the bedroom to the east: only 2 meters (6.5 feet), unusable. If basic issues don’t work, why discuss a chimney or a prefabricated shaft?!

Because you continue despite already recognizing lots of planning mistakes.

Later. A process doesn’t start at the end.

Nothing here is final yet. It won’t stay ugly either. Final means shortly before the building permit / planning permission application, which usually involves several revisions by the architect. Playing around is fine – you either play a beginner version and then leave it to the professional, or you plan alongside the expert. You can also rely on collective knowledge if the professional is a fraud.
A floor plan discussion here in the forum takes 6 hours. After that, it’s just repetition or small talk. The steam is out.
Now what’s really interesting is whether you’re budgeting 650,000 just for the house.

Thank you very much for your comments. I expressed myself poorly; from our point of view, the floor plan is nowhere near final. The issues you mentioned bother us as well. That’s why I didn’t want to unnecessarily occupy you here with the floor plan, but during planning, the question about the shaft came up. Anyway, now I’m wondering if maybe we want too much or have too high expectations. From your experience, is it possible to create a "dream floor plan" subjectively without major compromises?

Our ideas are: a large, closed kitchen in the southwest, living room in the northeast with a minimum distance of 4.30 meters (14 feet) to the TV, guest room on the ground floor, a shower bathroom on the ground floor, and a bathroom upstairs (two bathrooms upstairs aren’t a must). Bathroom upstairs facing east to be able to hang laundry over the garage (the washing machine won’t be in the basement – where laundry is generated it should be washed and dried), two children’s bedrooms in the west, and if possible, a straight staircase. All within a living area of 170-180 square meters (1,830-1,940 square feet).

Are these too many wishes, what do you think? As an inexperienced layperson, I can’t achieve these ideas without making at least one major compromise. I don’t want anything final, but at least a rough structure to work on by myself. Do you perhaps have a draft or a rough sketch you could share that I could develop further? It’s not about making it as easy as possible for me, but I really can’t make progress. No matter how I turn and twist it, I don’t feel completely comfortable, and now you confirm that for me.

Regarding the budget: yes, 550,000 to 650,000 is planned. The total budget is 1.2 million euros including the land but excluding landscaping.
