House Design
Planner: planner from a construction company (Heinz von Heiden)
What do you particularly like? Why?: small covered entrance area, semi-open living/dining area with sliding door, large sliding door on the ground floor, floor-to-ceiling windows on the southeast side of the upper floor
What do you not like? Why?: small utility room and too large bathroom on the upper floor, staircase was originally planned to be rotated by 180°
Cost estimate according to architect/planner: approx. €200,000
Personal budget limit for house including equipment: €250,000
Preferred heating system: natural gas and solar thermal

We look forward to your comments. If any details are missing, please just mention them.

One general question: The project planner from the house construction company told me that the chimney sweep’s escape window is not included in the plans because it is not relevant for the building permit / planning permission. Is that correct?

Regards

You basically walk past the attic to get to the washing machine. But ideally, you should be able to pass by comfortably, according to the current considerations.

In theory, the design is slim and straightforward, but in practice, you have to carry laundry baskets through the space.

We have 45cm (18 inches) thick “columns” in front of the entrance area and think it adds great value to the house.

Columns set with some space behind them from the exterior wall are different and would be designed slimmer than what is planned here.

Personally, I find the roof areas next to the gable quite wide already. An extension of the house is actually a topic for us.

I wasn’t necessarily referring to enlarging the house. Rather, either keeping the size the same but switching to a classic rectangular floor plan (which will conflict with the full-story requirement), or turning the captain’s gable into a somewhat more southern German “Wiederkehr.” It just needs to be traditional—though which tradition isn’t defined. These kinds of zoning regulations often achieve exactly the opposite of what they intend.

Our plot is located in the residential area “WA 2.”

With the circle around the “II” — meaning the requirement for a second full story is mandatory.
In the general residential WA2 zone, the top permitted full story must be designed as an attic with either a gable roof or a half-hipped roof .

This means that the top floor should be a pitched attic as planned, but it must count as a full story.
No specification is made for the knee wall height.

This is a strong hint that if a roof pitch of 30° (which is almost never enough) to 50° (already a much better starting point) alone isn’t sufficient in terms of floor area to create a full story, raising the knee wall height is necessary to meet the full-story requirement. In my opinion, a Frisian house stops being traditional once the knee wall is one and a half meters (5 feet) high. But then again, the people from Brandenburg aren’t exactly genuine Frisians anyway ;-)

This means: as planned, it should be an attic floor with a sloped roof but it must be considered a full floor.

If this were true, it would be a completely opposite view to the statements we have received so far.
I have now tried to read up on the term "full floor" a bit. Apparently, there are different definitions depending on the federal state.
Section 2, paragraph 4 of the Brandenburg Building Code states the following:

Full floors are all above-ground floors whose ceiling upper edge exceeds the average ground level by more than 1.40 m (4.6 ft). Floors used solely for housing technical building equipment (service floors) as well as cavities between the top ceiling and the roof covering, where living spaces are not possible, are not considered full floors.

Unfortunately, I cannot currently judge whether this somewhat general wording is positive or negative in our case.
The upper floor would, in any case, extend more than 1.40 m (4.6 ft) above the ground surface.

In § 2 paragraph 4 of the Brandenburg Building Code, it is explained as follows:

Unfortunately, I cannot judge right now whether this somewhat general wording is positive or negative in our case.
The upper floor would in any case extend more than 1.40 m (4.6 ft) above the ground surface.

Apparently, you are in luck! There was an amendment to the building code in Brandenburg. There, a storey is considered a full storey if it contains even just one habitable room. This is unique.

Therefore, what you want to build is permitted.

...if I understood everything correctly in my quick skim 😉

Exactly. Building codes are under the jurisdiction of the federal states. A typical approach — which underlies my and some others’ statements here — is to compare the floor area where a room height of, for example, 2.30 m (7 ft 7 in) is achieved with the floor area of the story below (and if it is two-thirds or three-quarters as large or greater, that upper level is also considered a full story). However, this is not mandatory; each state building code may view it differently. 2.80 m (9 ft 2 in) is an average floor-to-floor height. Therefore, 1.40 m (4 ft 7 in), as half of that, is often used as a reference to clearly classify a basement level as either a cellar or a ground floor in the sense of a “half full or half empty glass.” This is relevant when a development plan measures the eaves height from the ground floor level (so one cannot then arbitrarily decide which floor is the ground floor).

Such freedoms for a state building code result from federalism.

.

As I explained, this means: if the steepness of the roof alone is not sufficient to make the attic level have standing height on more than two-thirds of the floor area (measured against that of the ground floor), then it would practically require raising the knee wall, also called the "dormer wall," to increase the height.
