The Four room house is the name given to the typical mud brick Israelite house in the iron ageLevant.  It is so named because its floor plan, the only remaining portion in archeological sites, is divided in four sections. It is also called a pillared house because three ground-level "rooms" are separated by two rows of wood pillars holding the second floor.
The house masters lived on the second floor, the ground floor being used as a manger for animals and for storage.
