Excavation continued in 2017 along the western limits of this SU, but the depth was not reached. Only post abandonment layers abut this structure so far on the western side.

SU 8075 served as part of the western boundary wall of the area I structure. The wall segment to the north (8076) appears to be a later plug, suggesting that the northern limit of 8075 may once have represented the edge of an open doorway or hallway leading into Room I-4 from the west - this is also suggested by the apparent regularization of tufo stones along the northern limit. This wall may relate to an earlier phase of the structure, reused in the latest phase.
