Brandenburg: Gallery level/attic floor

The Building Code of Brandenburg does recognize full storeys and non-full storeys in terms of substance, but does not distinguish them linguistically. There are also people who take issue with the term Unkosten, which is basically "the same thing in green." Nonetheless, it makes no sense whatsoever to confuse the average height above ground level of an underground storey with the standing height of an upper storey (which per se are not underground). It is apparently currently fashionable to misinterpret building regulations.

What does the development plan say about roof extensions?

Unfortunately, the development plan is silent on this.

I have now varied the roof geometry a little and hope that this variant with an approximately 2.80-meter-wide flat element will also be approved:



This would result in a height of 2.6 to 2 meters at least over half the width at the top.



If it works out with a horizontal element similar to a mansard flat roof, we would already be very satisfied. Around the new development area, there are houses that represent everything the 90s and 2000s had to offer in trends: staggered shed roofs, butterfly roofs, barrel roofs, etc. Obviously, all higher than 6m. But prior to the citizen participation for the development area, there were massive objections from these homeowners, and therefore it has now been regulated quite strictly.

575 cm ridge height will never result in 2 stories each with 260 cm usable room height. You must not forget floor, ceiling, and roof construction and the 575 cm ridge height is measured from the outside.

Is the plot flat? How big should the house be? In my opinion, it's going towards 14m * 12m.

You are already 7 m high, right?

You should have something like that done by an architect. Preferably one who is familiar with the local building authority.

A flat roof is not at least 20 degrees inclined.

I repeat my inquiry from post #5

So what is it now, 38 or 34 m?

Is such a roof technically feasible and sensible at all? And why these contortions, when more space is allowed? Why does it have to be a "gallery"?
