Wall SU 5349 reuses block 5483 within the construction of the wall. It is built against and in line with 5484 (tufo block). Because of the similar structure on room 10's eastern limit with large ashlar blocks, like those of SU 5481 and 5482, we can presume that the wall was the outmost wall of a structure. Wall 5349 corresponds to the latest floor 5320 in room 9 and, along with walls 5348, 5351, and 5350, represents the latest phase of room 9 extant.
