Single-family house south slope - floor plan planning, tips?

You have a difficult hillside plot and want to build 3 floors. This is not for an amateur, believe me.

A floor plan is created by the architect, whom you have to pay anyway in Germany. Therefore, it is not necessary for you to struggle with it yourself. Just write down in text form what you need, bring a corridor plan of your property (with elevation numbers), and find a professional you trust.

Come back with the result, and then we will gladly help you optimize the details. But the rough plan must come from the architect. Anything else is not worth discussing given the size of the construction site.

Alright. I’m going to the planner ... it’s already planned anyway. I just like to envision my own house myself. And I can understand that the forum does not want to deal with amateur designs. So I’ll leave it at that for now.

Thanks anyway for the feedback so far!

Without measurements, the assessment is almost impossible. The quality of your information is really poor. Sorry. I only see that the guest bathroom is terribly laid out.

I count 250 sqm including the basement but without the attic. For office rooms and kitchen, I assume you unfortunately have to apply the prices for "normal" living space here.

You might not be aware of it yet, but this will blow the architect's estimate—and not by a little.

And even if you only want the floor plan to be evaluated, it only makes sense to evaluate floor plans if they are also financially feasible.

If you have €100k more than the architect’s estimate, many here will gladly continue

Ok, then I have so far misjudged the work here in the forum. Sorry for that!

I don’t understand "have €100k more than the architect’s estimate." What do you mean by that?

And I can understand that the forum does not want to deal with amateur designs. So I'll leave it at that for now.

But we do, even regularly! But it takes more than a drawing like "The SIM 4," which we have actually had before

I am curious about the floor plan from the planner.

EDIT:

The 3 floor plans basement, ground floor, upper floor together have 250 sqm of living space. I leave out the attic. You skillfully did not count all the corridors.
Also, the basement has residential quality, meaning it costs as much as the ground floor and upper floor.

We calculated for new buildings in 2019 with €2000 per sqm of living space or €400 per cubic meter (at least my architect calculated with that in 2018).
Which surprisingly works quite well for a medium good standard. And that without additional construction costs (house connections, civil engineering, drainage, fees, architect, energy consultant, etc.), exterior facilities, kitchen, garage, etc.

I think it will become clear now! I am currently also building with an architect, with a basement and a slope, so I know what I am talking about when I tell you that your €480k-€500k will not be enough. Unless it becomes a shell house and you do everything, absolutely everything yourselves.

I don't understand "having 100k€ additional to the architect's estimate." What do you mean by that?

I'll summarize it again:

- Currently, you are planning a floor plan that you possibly (presumably) unfortunately can't even afford.

- That means your effort and the ideas of the forum members are basically "for nothing" (as they say in Erzgebirge dialect).

- If you now involve an architect in further planning, he will have to make a cost estimate, which often turns out to be off because he only has to estimate with xx% accuracy (I don't know the exact percentage right now). Since he wants to initiate the project, supervise it, and earn money, he will initially estimate as cheaply as possible so that you don't cancel beforehand or he doesn't have to re-plan smaller.

- That means you need an additional buffer depending on the type of project: besides the typical add-ons, a hillside location always offers a lot of potential for unforeseeable earthworks and foundation costs, so a 20% buffer would be quite reasonable at the very beginning... which in your case could amount to up to 100,000€.

- Conclusion: Architect’s estimate + 20%: --> Check feasibility/financing with the bank. Otherwise, everything was for nothing.

Ok, then I have so far misjudged the work here in the forum. Sorry for that!

We cannot guess measurements yet
However, it is rather the case that _you_ _misjudge_ your work.
Should we praise your amateur floor plan, where you haven't even roughly thought through the staircase, so that you later say to the architect: exactly like this and not otherwise! Later you will regret it.
Be glad that we are so honest with you.

that the forum does not want to deal with amateur drafts

... is nonsense. It is clearly recognizable here as a builders' forum and not an architects' club.

You asked whether "one" first plans the ground floor, or what we advise: in the normal case (EG = entrance and living floor, OG/DG = sleeping floor) I recommend starting with the upper floor, because it is more detailed. Also, as a layman, one more easily "thinks" the downpipes "from above."

Then you stated that regional architecture was actually born out of necessity. Yes, but that is actually the root of all regional building cultures. And you are not exactly distancing yourself from it: I see your design as very D / A / CH alpine, and in basic terms it would have looked the same 300 years ago and built from log beams. Except for bathrooms instead of washing at the well or in the mountain brook, it is virtually an original alpine hut or a Maiensäß. Where a toilet is located, you tend to make the room as narrow as a bowling alley. Narrow stairs, cozy tightness, the alcove, the walk-through pantry—everything would have been built very similarly by an alpine herder back then. If you tell tourists that the practice was formerly the sheep barn, they would believe it.

With all due respect that every family may have its own personal culture of coziness, it seems to me that this only explains a small part of the peculiarities of your planning style, and a larger part is due to awkwardness that one is allowed to have as a layman.

A professional, who also does not have to be "an urbanite" and can understand you culturally well, will, in my expectation, come to a "more generous" architecture. Especially in mountainous regions—as I said, very similar to each other in D / A / CH and also I—a lot of building culture is newly interpreted, i.e. definitely transferred respectfully to the present.
