What counts as a privileged attic floor under § 17 bis KBV?
Solution extraite
A privileged attic floor exists only if the storey is built into the roof truss, with a roof slope or a reduced floor area compared with the storey below.
Motifs extraits
The provision and its materials show that only true roof-integrated attic conversions are exempt from floor-number and floor-area counting; a storey outside the roof space is not an attic floor.
