Houses had plaster interiors characterized by squared-off timber ladders or steep stairs. These were usually on the south wall of the room, as were cooking hearths and ovens. The main rooms contained raised platforms that may have been used for a range of domestic activities. Typical houses contained two rooms for everyday activity, such as cooking and crafting. All interior walls and platforms were plastered to a smooth finish. Ancillary rooms were used as storage, and were accessed through low openings from main rooms.
