As assistance for the OP: For the redesign from "without basement" to "with basement" the general contractor only charged 2500 euros. But I doubt that it will be just as cheap the other way around...There were almost 1000m3 of clay soil due to the slope and the backfilling with new material was also included. Clay soil is not suitable for backfilling....
