Notes for floor plan design desired

You basically walk past the storage room to get to the washing machine. But according to the previous considerations, you should actually be able to pass by comfortably.

In the considerations, you're slim and agile; in practice, you’re lugging a laundry basket around.

We have 45cm thick "columns" in front of the entrance area and find that they really enhance the house.

Columns with a gap behind them to the house wall are something different, and would also be designed somewhat slimmer than planned here.

Personally, I find the roof surfaces next to the gable already quite wide. Enlarging the house is actually a subject for us.

I didn’t necessarily mean enlarging the house. Rather, to either change it to a classical rectangular floor plan of the same size (which will conflict with the requirement for a full floor), or to convert the captain’s gable into a somewhat more Southern German style return. It is only supposed to be traditional – which tradition is not prescribed. For such reasons, these development plan requirements usually achieve exactly what they want to prevent.

Our plot is located in the residential area "WA 2".

With a circle around the "II" – so the second full floor is mandatory.

In the general residential area WA2, the uppermost permissible full floor is to be formed as an attic floor with a gable or half-hipped roof.

means: as a sloped roof floor as planned, it should be, but it must become a full floor.

No determination of the knee wall height is made.

is the hint that if 30° roof pitch (almost never enough) up to 50° roof pitch (already a significantly better starting point) alone is not enough to create a full floor area-wise, then by increasing the knee wall height the full floor must be fulfilled. In my opinion, a Frisian house with a knee wall of one and a half meters stops being traditional. But the Brandenburgers aren’t really true Frisians anyway ;-)

With a circle around the "II" - meaning the second full storey is mandatory.
This means: as an attic storey as planned it should be, but it must become a full storey.

So if this were to apply, it would at least be a completely opposing view to the statements we have received so far.
I have now tried to read around the term "full storey" a bit. Apparently, there are different definitions in the federal states.
In § 2 para. 4 Brandenburg Building Code the following is explained:

Full storeys are all above-ground storeys whose ceiling top edge protrudes on average more than 1.40 m above the ground surface. Storeys used exclusively for housing technical building equipment (installation storeys) as well as cavities between the top ceiling and the roof in which rooms are not possible do not count as full storeys.

Unfortunately, I cannot currently assess whether this formulation, which I consider somewhat general, should be evaluated positively or negatively in our case.
The upper storey would in any case protrude more than 1.40 m above the ground surface.

So if this were true, it would at least be a completely opposite view to the statements we have so far. I have now tried to read a bit about the term "full storey". Apparently, there are different definitions in the federal states. In § 2 para. 4 of the Brandenburg Building Code, the following is explained:



Unfortunately, I cannot currently assess whether this somewhat general formulation from my point of view should be seen as positive or negative in our case. The upper floor would, in any case, protrude more than 1.40 m above the ground surface.

Apparently you are lucky! There was an amendment to the building code in Brandenburg. A storey is already a full storey if it has even just one habitable room. That is unique.

In this respect, what you want to build is allowed.

....if I understood everything correctly with my quick skimming ;)

Apparently, there are different definitions in the federal states.

That's how it is. Building regulations are a state competence. Typical - and underlying my and some others' statements here - is to compare the area on which a room height of, for example, 2.30 m is reached with that of the floor below (and if it is two-thirds or three-quarters as large or larger, to also classify it as a full floor). However, this is not necessarily the case; each state building code can see it differently. 2.80 m is an approximately average measure for a floor height. Therefore, 1.40 m is often taken as half of that as a benchmark to clearly classify a basement as a cellar or ground floor in terms of a "half full or half empty glass". This is important when a development plan measures the eaves height from the ground floor floor level (so that you cannot then choose which is the ground floor).

Apparently, you are lucky! There was an amendment to the building code in Brandenburg. There, a floor already counts as a full floor if it has even just one living room. That is unique.

Such freedoms also arise for a state building code from federalism.

.

As I explained, it would mean: if the steepness of the roof alone is not sufficient to make the attic floor shaft-height equal to the ground floor on more than two-thirds of the area (measured against that of the ground floor), then you would practically have to pump it up by increasing the knee wall aka "Drempel".
