Single-storey calculation exceeded - possibilities?

Hello everyone,

I am building in an area where "single-story" is required.

According to the building regulations, the following is defined for the calculation of full storeys:

Step 1: Take the outer edges of the house in the attic and calculate the floor area.

Step 2: Now calculate 3/4 or 75% of that = 95.20 sqm.

Step 3: Finally, calculate the area that is higher than 2.3 m from the top edge of the floor to the top edge of the roof covering = 95.70 sqm.

So there is an excess of a ridiculous 0.50 sqm.

Are there possibly creative solutions here to still make it work? Otherwise, we would have to lower the knee wall and increase the roof pitch.

The construction company claims there are no more possibilities.
I then spoke with two lawyers (for construction law). Both said there are possibilities to raise the installation level in the floor area, provided it is not a manipulated/artificial installation level, then this would be fine and this increase would result in less than 2.3 m at that point. It makes me suspicious that two lawyers independently say the same thing while the construction company denies all alternatives and now acts as if they do not understand the lawyers’ argument... driving me crazy. After all, it’s only about a ridiculous 0.50 sqm.

Have you ever had something similar? How do you see it?

Kerstin

Simply take the inner edges of the rooms' outer walls, meaning subtract the insulation, then it will fit.

If one knew which federal state the area is located in, one could check whether the state building code is cited correctly. If one knew when the development plan became legally binding, one could check whether the correct version of the state building code was cited. If one knew what the building drawings (floor plans, elevations, and sections) look like and how the contractor calculated, one might be able to identify errors.

Die Baufirma behauptet es gäbe keine Möglichkeiten mehr.

There has to be a limit somewhere, and the planner should plan in such a way that this limit is not exceeded mathematically. If the construction company cannot manage to squeeze half a square meter, then they are useless.

Andernfalls müssten wir mit dem Kniestock runtergehen

For a 10m long house with a 45° roof pitch, that would be 2.5cm. Does this prompt you to consult two (!) lawyers?

Andernfalls müssten wir ... die Dachneigung erhöhen.

Why?

Daraufhin hatte ich mit zwei Rechtsanwälten gesprochen

Now, law studies are not exactly known for their difficult math exams. I think the architect owes you an approvable plan. The lawyers should check that better.

Where is the advantage of this compared to lowering the knee wall?

Here one would go down a bit with the knee wall for the submission of the plans. What one then builds..... no one will notice. K.

Hello everyone,

Thank you very much in advance for your feedback.

: According to the definition in Schleswig-Holstein, they measure the floor area from the exterior surfaces, meaning it wouldn’t make sense here to deduct the insulation mathematically. Maybe it’s different in other federal states.

: The company would never do that, because the risk is too high if a neighbor complains afterward.

The federal state is Schleswig-Holstein.

I spoke briefly with the two lawyers (they sit in the same office, no official commission :)).

The roof originally had a pitch of 21.5 degrees and a knee wall of 1.59 m.

After the change, the company wants to build a pitch of 23 degrees and a knee wall of 1.525 m.

It annoys me because we contractually agreed on 1.59 m and 21.5 degrees.

The idea with the installation level was meant that it would only be raised at one specific point in the attic, so for example the 2.3 m wouldn’t have to be counted there. The rest of the floor would remain the same. According to the information from the lawyers, this is acceptable if it is a genuine installation level and not a pure manipulation or artificial elevation.

I will upload the calculation again.

Thank you very much

Kerstin
