Hello everyone,

I’m currently looking into buildability according to §34. Basically, the content can be interpreted in various ways. What exactly counts as a storey? The internet offers all kinds of opinions. The only thing that seems clear is that there are no half storeys.

§2 (4) of the Brandenburg building regulations states:
Full storeys are all above-ground storeys whose ceiling height, on average, extends more than 1.40 m (4.6 ft) above ground level. Storeys used exclusively for housing technical building equipment (installation storeys) as well as cavities between the top ceiling and the roof, where living spaces are not possible, are not considered full storeys.

For me, this means that the attic of a typical single-family house (those houses with sloped roofs 😀) counts as a full storey. Does this mean such houses are actually two-storey? Because these are usually described as 1.5-storey houses, but that seems to be unknown to the building regulations. So, can I equate these houses with urban villas? At least when it comes to the number of storeys!

It’s a tricky topic and is probably regulated differently in each building code/state building regulations, but I’m curious to hear your feedback.

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

To me, this means that the attic of a typical single-family house (houses with pitched roofs 😀) counts as a full floor. Would these houses thus be considered two-story?

It depends on when the houses were built. To the best of my knowledge, the building regulations have been revised several times in recent years, including the definition of a full floor. If you are building today, I would agree with your interpretation.
