Some of the later houses in HR area were constructed on top of massive deposits of garbage consisting of brick rubble, broken pottery and sometimes a thin layer of crushed, vitrified terracotta nodules.
The foundations of many houses were constructed on top of massive mud brick platforms such as this one eroding from the edge of the mound along the major east-west street dividing HR and VS areas.
Narrow brick walls define the outlines of a small room or courtyard in the low-lying area between L and SD Areas on the Citadel Mound.
The pathway leading from VS to DK-I area follows the natural topography of the mounds. The eroding surface is littered with over fired nodules, pottery, brick fragments and other artifacts that are heavily encrusted with efflorescent salts.
One relatively successful low cost techniques used to combat the destructive nature of salts in the fired bricks is to cover the walls with a thick layer of mud and straw plaster and to spray them with clay slurry.
Standing in HR area and looking northwest at the juncture of Last Street (east west) and First Street (north south). VS area is seen on the other side of the street and the stupa mound rises in the background.
This general view of houses in VS area shows the color of the brick walls after the use of mud brick and clay slurry for conservation.
This general view of houses in HR area shows the color of the brick walls prior to use of mud brick and clay slurry for conservation. The lower parts of the walls have the natural reddish color of fired brick.
