Floor plan of a single-family house measuring 14x14 meters with limited ridge height

Furthermore, it would be sensible to always align different floor plans identically, preferably as they are intended to be placed on the property. And so that no one has to search repeatedly, it is best to always provide 2 drawings for each new planning contribution. Once the house with site plan and then only the house floor plan.

I agree with that, and it is unfortunately a bit difficult at the moment. I have actually conceptualized everything in Allplan (construction, BIM, pipes, etc.), but the program is unfortunately a bit sluggish on the laptop while on the go.

Budget does not match the house size or is unrealistic. For 350K, you won't get a 160sqm bungalow in Germany. Apart from that, I cannot see any exceptional talent that would allow you to take on the floor plan design independently. Who is your construction partner with the "steel skeleton"? Doesn't he offer any consultation?

Somehow, the money issue always seems to be predominant. We have the offer for the shell including the foundation slab at about 180k and yes, there is also an architect contract for 35k. There are already enough examples here in the forum where forum members have shown that costs of 2-2.5k are plausible if the settings fit: own work, village, enough time, no 0% financing, etc. My concern in this thread was more about the floor plan and ideas that I could incorporate into the further planning.

At the moment, for example, we are struggling a bit with the guest bathroom, which has no window.

I would see a guest bathroom without a window as one of the smaller problems or as unproblematic, provided it is a guest bathroom that is only used rarely.

In the current draft, it is a central hallway

Currently, you show two hallways, separated by a sliding door. The excess interior space is due to the shape and is difficult to integrate; the sliding door is not only unnecessarily expensive but also uncomfortable to operate.

The hallway will get light through the glass door to the living room and a strip of light next to the exterior door. Unfortunately, no more is possible.

It remains dark, and it is possible, but not if you consider such a plan as fixed.
The floor plans #1, #6, and #8 are completely different and, in addition, one is upside down. How is one supposed to recognize the cardinal direction on top of that?
Which one applies now?
If it is #6 now, I would also be interested in the dimensions of the indicated staircase. In plan #8, no staircase is visible.
It is extremely inconvenient that the children's room is accessed from the vestibule, whereas the heating room is closer and practically in the living area.
Upon entering the guest bathroom, you stand inside the shower. A bathroom with 20 sqm requires good planning; otherwise, it will end up as is often done by laypeople, where something is attached to the sides (toilet, washbasin, etc.) and the unnecessarily large middle area is wasted. Is there a more detailed plan on this, because as it looks now, it does not look good at all. The dressing room has an apparently endlessly long wall; this also will hardly be possible to design in a cozy way, and this room also looks unattractive, as if it ended up like this because there was no other space left for it.
This is also how it appears to me overall, and not like a living layout created from the inside, according to individual needs, with the goal of creating at least a charming living feeling.

There is also an architect contract with 35k

But he surely has not seen this yet, right?
I would rather have the architect design it completely anew, because the current layout would go straight into the round file with me; that's what you have an architect for.

Thank you very much for the input! Floor plans in #1 and #6 are from us and already oriented. #8 was a suggestion that is relatively similar at about 14x15m, but it was only a suggestion and except for the window in the guest bathroom it has rather disadvantages, which you have already described (corridors, dressing room as corridor, huge bathroom, etc.).

What is included in the shell construction? For me, the shell construction without roof and [Femster] was about 50% of the construction costs.
