The SU is a possible wall of unknown purpose and age. It appears truncated on the north and south limits, but this is still uncertain. It possibly predates 2262, as the southern blocks appear to be cut by the foundation trench for 2262 (irregular break in the rock). The other stratigraphical relationships are unclear. It was determined to pre-date walls 2354 and 2262. During post-excavation study, this feature was reinterpreted as a stretch of wall running north-south at the eastern limit of Space 8, which might delimit the property block and separate it from the eastern Area C Road.
