Installation shaft and chimney shaft in one?

You can get this for approximately 650,000 EUR in construction costs including ancillary building costs. Including a garage 10x6 m with gable roof, partial basement, wooden windows, solid wood parquet.

With your budget my advice to you: Get a good architect.

If you are not exactly sure that your floor plan works, you go to the architect without any drawing and tell him what you want.
You have already written here yourself what you want with [Küche] [Tv] etc.

Stupid question, but why don’t you enlarge the guest WC on the ground floor with a shower instead of squeezing another bathroom upstairs? - then the guest room benefits from it too. Currently, 2.24 is planned for the wardrobe in front - 1.40 or 1.20 would also be enough.

That’s not a stupid question at all; that’s exactly how I changed it based on the criticism here, so that indeed you end up with a wardrobe of 1.60 meters:

You can get that for roughly 650,000 EUR in construction costs including incidental building costs Including garage 10x6 m with gable roof, partial basement, wooden aluminum windows, solid wood parquet. Given your budget, my advice to you: Get a good architect.

Am I interpreting this correctly: If you're already investing that much budget, then don't skimp on the architect? How much total living space does your house have? It at least looks very spacious! Is it "only" partially basemented because of costs?

From your experience, is it possible to subjectively achieve a "dream floor plan" without going through one or more deaths?

Are these too many wishes, what do you think? At least as a dumb layman, I can’t manage these ideas without dying.

Why do people "die" when planning well? Yes, if a layman approaches it, then these "deaths" are much more likely to happen because a layman has no idea what is all doable.

Our ideas would be: large and closed kitchen in the southwest, living room in the northeast with a minimum distance to the TV of 4.30 meters, guest room on the ground floor, a shower bathroom on the ground floor and a bathroom on the upper floor (two bathrooms upstairs is not a must), bathroom on the upper floor facing east in order to be able to hang laundry on the garage (washing machine will not be in the basement – where laundry accumulates it should be possible to wash and dry),

In the meantime I wonder whether we maybe want too much or have too high demands.

You will get all the requirements you listed into your house. But if every little extra is only possible by complicated installation or execution, then your budget simply won’t be enough.
Your garage plus basement already amounts to €150,000. A fireplace generally €10,000-15,000... in elaborate fashion then €15,000-20,000 (or so), if you mean that with requirements.

And this forum has become your hobby? :cool:

I find it a bit presumptuous to judge the users here who answer your questions.

Even if sometimes gives unpleasant or complicated answers, that does not mean he has less expertise than you.
And if it is a hobby for him, then it is more successful for him here than your new hobby of planning your house.

Go to an architect and come back with the architect’s plan to discuss it.
A house plan cannot work by a layman planning and then having finicky executions discussed in a forum of homeowners.
