One of the adaptations made to Palladianism in America was that the piano nobile, now tended to be placed on the ground floor rather than above a service floor, as was the tradition in Europe. This service floor, if it existed at all, was now a discreet semi-basement. This negated the need for an ornate external staircase leading to the main entrance as in the more original Palladian designs. This would also be a feature of the neoclassical style that followed Palladianism.
