Floor plan, Bauhaus style with staggered floor

A setback story (so that it is not a full story) must, among other things, be set back by one meter on all sides. [...] In my eyes, that is essential for a setback story.

Where in this statement is the dividing line between "must" and "in (your) eyes essential"? Is that a NRW specialty? - I think I have also seen setback stories on non-row houses, which for example only stepped back behind the street façade.

Thank you very much!

The volume of the ensemble seems awkward to me. On the garage side, I would not let the upper floor also recess sideways, but rather away from the front.

The first idea was to cover the entire left area of the ground floor with the upper floor, but currently, that would be too much area for the recessed floor.

I don't like the staircase at all. An L-shape could be attractive here.

Same position? L-shape would also be okay?

The clarity/understandability of the sketch for outsiders leaves much to be desired ...

I understand, it is actually only meant to illustrate the dining and living area. I will upload a new sketch tomorrow.

But I see no recess at the front or back. In my opinion, it is essential for a recessed floor.

The recess is minimal and according to the architect sufficient.

Is that a NRW specialty? - I also think I have seen stepped floors on non-row houses, which for example only recessed behind the street frontage.

But you cannot tell from the houses whether they are considered two-story on paper or not.

Is the OP sure that a flat roof is allowed? Are there height restrictions? Cladding with facing bricks was mentioned, which is probably considered untypical for this architectural style. Is there already an idea of what the brick should look like? We are also building in this style and facing bricks would only have been conceivable in those extremely long formats (= expensive), everything else doesn’t look right on the little cube.

One thing is what the legislator prescribes, the other is my opinion. A stepped story of a terraced house logically does not have to step back on all sides if it is attached on one or both sides, as long as all other conditions are met. There are federal states where it is sufficient that one side steps back. This is not the case in NRW.

There was talk of brick cladding, which is probably considered untypical for this architectural style.

Misunderstanding "Bauhaus" as "mainly flat roofs" was already "typical" for several building cohorts from the mid-70s to the mid-80s. Respectively for a gable roof revolt by architects of that time who would have liked to have been part of the '68ers. Legalize Klinker

It was mentioned to use facing bricks, which would probably be considered untypical for this architectural style.

Why? Mies van der Rohe was probably a very well-known Bauhaus architect and just look at his Bauhaus houses "Lemke in Berlin" or "Haus Esters in Krefeld" or "Haus Lange." This is still how very modern buildings are built today. Facing bricks and Bauhaus are not mutually exclusive, only each feature on its own already drives construction costs up. Together, it is likely to be an expensive affair.
