SU 8158 is part of the north-south wall on the east side of Room I16. It continues as SU 8157 to the north (on the other side of a plow scar), while it's southern limit (and presumed intersection with walls 8039 and 8160) has also been destroyed. However, based on construction technique (poorly made petite appareil) and it's relationship to the leveling layer for Room I16, this wall appears to be later than the majority of the structure to the west.
