Sensitive topic: What counts as 1-story/2-story?

Hello everyone,

I am currently dealing with buildability according to §34. Basically, the content can be interpreted in various ways. What counts as a floor? The internet provides all kinds of wild things. The only thing that seems clear is that there are no half floors.

§2 (4) Building Regulations Brandenburg states:
Full floors are all above-ground floors whose ceiling upper edge protrudes on average more than 1.40 m above the ground surface. Floors that are exclusively used for housing technical building equipment (installation floors) as well as cavities between the top ceiling and the roof, in which rooms for living are not possible, are not considered full floors.

That means to me that the attic of a normal single-family house (houses with pitched roofs :D) counts as a full floor. Are such houses therefore also two-story? Because these are usually always described as 1.5-story, but this seems unknown to the building regulations. So can I equate such houses with city villas? Of course, referring to the floors!

A delicate topic, which is certainly regulated differently in the respective building codes/state building codes, but I am curious about your feedback.

Only that there are no half floors seems to be clarified.

That is the common term for the attic, regardless of whether it is a full floor or not.

§2 (4) Building Regulations Brandenburg states: Full floors are all above-ground floors whose ceiling top edge on average protrudes more than 1.40 m above the ground surface. Floors that serve exclusively for housing technical building equipment (installation floors) as well as cavities between the top ceiling and the roof, where rooms for occupancy are not possible, are not considered full floors.

To me, that means that the attic of a normal single-family house (the houses with pitched roofs :D) counts as a full floor. Such houses are therefore also two-story?

It depends on when the houses were built. To my knowledge, the building regulations have been adjusted several times in recent years and the definition of full floor has changed. If you build today, I would see it as you do.
