Single-family house, staggered storey, prefabricated construction method

Otherwise, I would place the house closer to the street and orient the main garden towards the east.

I would just be afraid of creating too much shade for myself with the house. Sure, the view of the forest to the east is lovely...

It's about the fact that you are throwing away unnecessary money by simply partitioning large rooms or awkward spatial relationships unplanned, where the dimensions are then not even utilized.

Sure, the bathtub will never be placed as awkwardly as shown. I found the space utilization especially reasonable in the master bathroom you mentioned as well as in the dressing room. There is probably an even more sophisticated way, but then we could start again from scratch without changing everything. As I said, we are basically working on revising the layout fundamentally.

Basically, think about the roof terrace, or whether a setback floor, as it is currently planned in terms of the proportions of the ground and upper floors, makes sense.

This is due to the fact that only 1 full floor is allowed and therefore the upper floor in Hesse can be a maximum of 75% of the ground floor area. And honestly, we like the large roof terrace.

Which prefabricated house is it?

Okal Haus.

unless another development east of you is planned in the near future.

You can be quite sure that in twenty or thirty years the next construction phase will follow there.

We have basically redesigned the ground floor (of course in an amateurish way) and will ask the prefab architect to implement it in the plan.

From a certain degree of "renovation" it no longer makes sense to take a basic design X, and it is better to opt for Y or Z. If it absolutely has to be a prefab house and from Hesse, I would consider Bien-Zenker or Rensch-Haus to be a realization closer to the wishes than Okal Haus.

I would reconsider the open wardrobe. I imagine that because it is a walkthrough room, it would quickly gather dust there. Bien-Zenker does have nice floor plans! If you have or want cats, they will surely appreciate a few cozy spots on fresh laundry.

I found the use of space quite reasonable, especially in the master bathroom you mentioned as well as in the dressing room.

The usage cannot be rated positively: normally you can plan a walk-in shower without a shower door in a 12 sqm bathroom, which is not visible here at all. Of course, if you mention that everything will be different, then please just draw it in, because as I already reported at the beginning: a parallel thread now has problems furnishing a 2 meter wide bathroom. With your 2 windows, you also cannot plan generously, a lot has to be refined.
In the dressing room, you have drawn 3 meters of closet space. Ideally, because you cannot get standard furniture with a width of 240 cm. 3 meters of closet space do not need more than 8 sqm of room. So if you furnish this room as drawn, it might currently be sufficient for you, but sufficiency quickly turns into inadequacy, as soon as you consider pregnancy clothes, two clothing sizes or five years ahead.
Furthermore, there is no window there, thus no natural light. It is to be assumed, also because you have no vacuum cleaner/cleaning/hwi/luggage room upstairs, that sooner or later it will become some sort of junk room.
I would thus find a dressing room of over 8 sqm great, but definitely plan a window in such a room and at least 4 meters of closet space.
I come back to the steak plate again...

It’s probably possible to do it more cleverly, but then we would have to start all over again without everything changing.

No, nothing more clever, just more effective!
And yes: in your place I would start again from scratch or learn from mistakes, which is never going back to zero but developing something, i.e. planning.
As I have already said, I do not see any planning here.

This is due to the fact that only one full floor is allowed and thus the upper floor in Hesse may be a maximum of 75% of the ground floor area.

And honestly, we like the large roof terrace.

Exactly, but then just think about whether this house is the right one on a plot where only one story is allowed. Even if you get the building permit, a roof terrace as well as the garden must be maintained in parallel. If the kitchen is downstairs, you will probably sit less upstairs under the palm trees. If you maintain the garden downstairs, then you do not have the palm tree upstairs under control.
And yes: a recessed top floor is one way to legally circumvent the one-story restriction, but there are other possibilities as well. Doesn’t Okal Haus have an architect who plans?

I don’t care what you build... I pointed out that you plan a house with regard to the plot and not only the house; the proportions should be right not only in the house but also in the rooms.

I do not see all this here, and I believe you have not weighed many things yet.
Of course, a roof terrace is great – in a city house where you can use and maintain it.

Okal Haus.

The point of this question is that you can compare what the original was and what was negatively changed. Ultimately, you rely on a model house which is to be altered according to personal wishes and the plot. And if a lot does not fit, you have to go back to the origin.

You should simply think about the objections and not just explain or justify them.

We would be happy about criticism and suggestions...

You got it. I’m done.

, first of all, a big thank you for your criticism. Just writing so much and taking the time to think about someone else (us) deserves respect

A few words nevertheless:
- A walk-in shower in the master bathroom is already planned, the plan might be misleading here (it just says 90/90, but it is bigger).
- The dressing room has 2 wardrobes of 2.40m each. Since it is supposed to be an open wardrobe or just a frame without a corpus (at least for now), there should be either a skylight or, in the case of a flat roof, even a roof window above the dressing room at the top of the plan.
- We have already met an architect through Okal Haus and told him our wishes. The basis was a split-level house from Okal Haus. But maybe - in combination with our wishes and the rather tight specifications regarding the rooms, stairs, and orientation - we have set too narrow limits. Should the architect decide more on his own? What should I tell him? "Split-level, open kitchen, and space for 3-4 people... now go ahead"?
