In (Austrian) German, does Parterre refer to any ground floor and Hochparterre refers to a raised one? Or do they both technically refer to a raised ground floor? (In Romania, almost all ground floors are unfortunately raised until very recently…not great for accessibility.)

Hoch means 'high' and tief means 'low', so there's Hochparterre for raised, Parterre for normal and Tiefparterre for below street level
