Should the entrance be on the Piano Nobile?

I’m conversant in the concept of the piano nobile, however I'm mainly asking whether or not, for residences, it’s higher to have the piano nobile nearer to the bottom with {a partially} submerged decrease degree and the doorway between the columns, or to have the decrease degree totally expressed with the doorway on the decrease degree. My ideas are that it appears to be extra widespread for the doorway to be between the columns on the lowered piano nobile for residences, whereas authorities buildings, museums, courthouses, and palaces appear to have their decrease ranges totally expressed and their entrances on these decrease ranges. What are your ideas?

The photographs alternate between entrance being on the piano nobile and entrance on the expressed decrease degree.
