Floor plan options single-family house 130-150 sqm, 1.5 stories, hillside location

This thread is somehow unfortunate, I think. Your property is not simple and you are looking for initial ideas, which is okay. But asking for advice on a slope with several catalog designs only motivates hardcore forum members. Your own designs don't really get you much further either, I'm afraid. Yes, there is some forward development but fundamental "mistakes" make the matter, in my opinion, unacceptable. Your staircase is a chicken ladder – what floor height is it supposed to overcome? I'm not even sure if it meets the DIN standard, it is far from comfortably walkable. The terrace is also not exactly from the dream house factory. Narrow and squeezed against the property boundary. Who wants to sit there? But the real killer are probably these fantasies:

Für Wohnkeller rechnen wir mal 100k, Baunebenkosten weitere 100k, dann Haus nach Möglichkeit maximal 400k + 50k€ Ausstattung/bisschen was für Außenanlagen

I would advise you to talk to an expert you trust about your possibilities. I see only 2 floors on the slope with this budget – but perhaps somewhat bigger overall if the building envelope allows it. Maybe you also increase the budget – no idea. But as it is, everything is very inconsistent and confusing. Too vague for a serious discussion.

Then I’ll ask differently. Regarding the finished floor level, has already answered. Is there a development plan? What does it say about heights? Reference points, etc.?

I already mentioned the planned finished floor heights above; for the ground floor finished floor height, the development plan specifies a range from 920.5 to 921.1 m. I marked the 920 line in the floor plan. Otherwise, it is an 8.60 m ridge height and a 3.6 m eave height (the latter is regularly exempted; we are also planning this for better KN).

UG / EG means without basement. UG as living area.

Well, we gave it some thought, but regarding the basement rule, we were quite clear on the case: it costs about as much as a slab foundation without any real added value. Due to the fixed finished floor height on the ground floor, terrain would first need to be created (good: excavation can be used; bad: must then be properly secured/piled/retaining walls – a lot of money for no gain). Assuming you lower the finished floor level, the old basement would simply become the new living space – sure, conceivable, but deliberately giving up height on a slope is also counterproductive. But I’m open if there are better solutions; maybe I just don’t know them yet.

Your staircase is a chicken ladder - what story height is it supposed to overcome? I'm not even sure if it meets the DIN standard, it is far from comfortably walkable.

Oh, that would interest me now, what do you base that on, what should we pay attention to here? Aren't those more or less standard dimensions? It should indeed remain comfortable to walk on..

The terrace isn't exactly from the dream house factory either. Narrow and squeezed against the property boundary. Who wants to sit there?

Hmm, if 3m narrow and 4m distance from the neighbor's boundary is excluded, how are people with even smaller plots supposed to plan the terrace? But maybe I'm not thinking big enough yet (although I'm rather being drilled in the opposite direction :D).

Regarding the general thread flow: Yes, I fully agree with you, unfortunate outcome or no longer very inviting.

If you have read the introductory thread for this forum section: , then typical stair dimensions are also provided there.

There are online staircase planner tools. Just Google "Treppe 1x1". However, the DIN alone is not always satisfying. Important are dimensions that are comfortable for everyday life over a whole lifetime. For example, at least 26 cm tread width, max. 18.5 cm riser height, at least 1 m stair width, whereby you should add at least 5 cm on the left and right for the stringer or railing. So, for example, I never plan a U-shaped staircase under 2.20 m width.

Hmm, if 3 m narrow and 4 m distance from the neighbor’s boundary fails, how are people with even smaller plots supposed to plan the terrace? But maybe I’m just not thinking big enough yet (although I’m rather being brainwashed the other way :D ).

It is never about what others do with their land; what always matters is your land. The terrace is one of the main living spaces. Its location should be well chosen – a place to feel good. At the garden fence to the neighbor, in my opinion, it is not exactly cozy and intimate. 4 m distance is rather nothing there. Let’s assume the neighbor puts his kids’ trampoline right at the boundary... and they do that regularly. Okay, that thing annoys even at 8 m but just somewhat less. Of course, you can always have luck or bad luck. I just wanted to make clear to you that, in my opinion, the basic concept is still lacking before going into details.

I have to be honest and say that the initial thread confused me more than it informed me.
Street to the south, uphill to the north… but none of it fits the floor plans for me or made any sense. It got to the point where I wondered whether it’s about basement, ground floor, and attic or just lower and upper floors.
I don’t mind posting a standard house floor plan here, but three of them with strange and unclear accesses to me… Then the nice initial situation of being allowed to build an open basement to the south, which you ruin with symmetry and the house entrance between two cellar rooms.

Access via a balcony

And then you even plan a barrier to the garden :(

To put it differently: It’s not about the exact details, it’s clear that somewhere in the northwest (so top left) the "less important" things like guest WC, potential pantry, and possible exit to the north garden should be placed.

No, why?! Nothing is certain at all. Maybe that will result at the very end of the planning, but I would consider all, all possibilities.

Since the entrance should be in the basement (cellar), any entrance facing the street would spoil valuable south side - accordingly, catalog designs were consciously chosen with both stairs and entrance on the north - basically, a free plan would probably lead to a similar variant but would then save the exit to the north for cost reasons.

There is the possibility
- to place the entrance on the east side in the basement.
- to place the entrance on the east side on the ground floor.
- to put the open living area in the basement with a great terrace to the south and give the children on the ground floor the great view to the south. Meanwhile, the parents’ area faces the garden…
- to extend the open living area, as you plan, on the ground floor over the south and west sides. However, I would not make the mistake of ruining the south side of the basement with utility rooms.

You can nicely separate entrance and terraces with hedges, planting, or a small wall and create privacy. I assume no double garage for lack of budget.
If you explore and consider all possibilities, you might even get by with only two floors. The roof could be open inside or a staggered shed roof, so that this way you bring southern sun into the north rooms.
So: if you trust the basement a bit more than just a central corridor with utility or at most

Here now the current floor plan. Entrance as usual in the cellar in the middle, south is at the bottom.

May I ask what you mean by that? Our basement is also supposed to contain living rooms - we have a wall facing south -

…you spoil it with a sauna that should be rather private and not planned on the street side and also does fine without a south side - if necessary, just a basement window.

In principle, I find your living and sleeping rooms on the ground and attic floors quite good. Except for the fact that you actually have nothing, absolutely nothing, from the property in the “living” area. The only connection would be in the “back left,” unfortunately without a terrace door and furniture on the wall side. I would rather consider creating the open living area with kitchen and entrance in the basement, then on the ground floor towards the garden the utility/storage room with sauna, children’s room, and family bathroom, and on the attic floor the parents’ area and office.
