This is from memory and things may be different now.
If a 2 story house was advertised as 100sqm then that was the internal area defined by the German building codes as habitable space.
The house could have a full multi room cellar but this would not be part of the 100sqm as it was not habitable (unless there were windows which made up a minimum percentage of wall area ).
If the upper floor had sloping ceilings due to the angle of the roof then any floor area with less than 1.5m (I think) would not be part of the 100sqm as it was not habitable space.
My memory is failing but I think there was some ruling that not all of the bathroom or kitchen space could be classed as habitable but I'm unsure abut that.
Unlike UK where you can describe a one car garage as a bijou studio apartment, Germany has strong views about what makes up living space.
