Planned new single-family house - floor plan available

You are surprised at several points: "Effizienzhaus" sounds like energy-conscious builders, but that clashes diametrically with the extreme envelope-to-volume mismatch of the jagged building structure. Then I read about timber frame construction, but see window dimensions that rather suggest a stone house design. I can believe the bricks as a specification, but I thought the green roof was a misinterpretation when reading the development plan. You then clarify this in post #4 – however, this means that this house design is already dead. However, it is not a pity, especially the upper floor is a failed attempt: the 9 sqm room exemplifies the saying "too much to die, but too little to live" in the sense that as a secondary hallway in the style of a corridor it is wasteful, but as a dressing room it is too narrow. The other two rooms are unfurnishable, even if their intended uses were swapped.

The ancillary building costs are missing, everything that is marked "bauseits" and what is not listed.

I would omit a few angles.
Why is the upper floor positioned so centrally and not on the exterior walls (structural engineering)?
Is there already a calculation from the structural engineer?
If not, the budget will not be sufficient.

The hallway is too big, the bathroom is a wet cell, a freezer does not fit in the pantry.

Please draw all desired and existing furniture to scale in the floor plan.

Thank you very much for the opinion.

I also agree regarding the hallway being too large.
The bathroom downstairs is intended only as a guest WC and in the future as a children’s or youth bathroom. (I didn’t have a bigger one myself at the time either).
No freezer is supposed to go in the pantry. The kitchen has already been designed so that a side-by-side refrigerator fits.

I don’t quite understand the suggestion to omit the angles. Please help me with that.

Personally, I find the centrally positioned upper floor visually much more interesting than if it were placed at the edge.
Maybe it will become a little clearer with the picture.
Regarding the structural engineering, I cannot make any statement yet. For now, we had it planned accordingly by the builder.

I can believe the brickwork as a requirement, but I thought the green roof was a misinterpretation when reading the development plan.

However, it is not a shame either, especially the upper floor is a failed attempt: the 9 sqm room embodies the saying "too much to die, but too little to live" in the sense that, as a secondary corridor like a gallery, it is wasteful, but as a dressing room it is too narrow. The other two rooms are unfurnishable, even if you swapped their designated uses.

Thanks also here for the feedback.

Have I, or rather the builder, misunderstood the flat roof issue – i.e., is it not even possible?

I also see the 9 sqm room as too narrow.

How am I supposed to understand that? Various items are at least included in the shell offer. Specifically: green flat roof, wooden facade, and clinker according to the offer included.

Yes, but all outside of a standard. I only answered your question about the rounded 200,000€ question.

Ground floor: 2 children's rooms, 1 utility room, 1 office, 1 pantry, open living-kitchen-dining area Upper floor: 1 bedroom, bathroom, walk-in closet

May I ask why you are planning for upstairs when you don’t even have children yet? What if none come?

9,218 the closet

I’ll make it short and painless: the dressing room is hardly furnishable. And if there were one or two wardrobes, you would have to squeeze through... no way through two... sorry, but I would redo a lot there. Regarding the exterior view, I expect somewhat more designer aspects inside. As a guest, I would not feel like using the small children’s bathroom. Compared to that, the children’s rooms are rather small. This happens more often with childless builders.

May I ask why you are planning the upper floor when you don't have children yet? What if none come?

You may... We want a separate parent area or sleeping area with peace from the rest of the house. Regardless of whether children come or not. Possible ideas on how to design the upper floor differently to avoid the narrow dressing room or to allocate space from the large hallway downstairs for the bathroom? On the subject of the size of the children’s rooms, I am exceptionally of a different opinion. I lived in just 11.* sqm myself until the age of 25. (The average German moves out only at 25!!!)

On the topic of the size of children's rooms, I am for once of a different opinion. I lived in a room of only 11.* sqm until I was 25 years old. (the average German only moves out at 25!!!

You should reconsider whether you should compare everything to your childhood. Then was then and now is now. It’s already the second time and very different to consider. Besides, I don’t believe your parents had a €450,000 house with a parent's wing, which is quieter than that of the children.
