The pressure of the walls on the foundation (and on the ground) depends on the weight of the wall and the part of the building adjacent to it. Under the influence of the weight of the building, soil compaction (subsidence) occurs. If the building was built unevenly in height, then uneven soil subsidence would occur under it. And this could lead to accidents.
