Many times, we see differential settlement at a rear room of a house. This will manifest itself with a floor sloping downwards towards the rear and cracks, either at the interior, the exterior or where the walls of the rear room meet the walls of the rest of the house. Sometimes these are at rear additions and sometimes they are part of the original construction. In many cases, we then further observe that the rear room is on a crawlspace foundation while the main house is on a full basement.
