The wall is similar to SU 2032 in terms of construction technique, but the two features do not follow the same alignment. This perhaps indicates that the blocks may have been reused from a different structure. During post-excavation study, this feature was reinterpreted as a wall foundation marking the northern limit of Space 2. A part of this wall was subsequently reused in Phase 2. It is possible that this stretch of wall foundation could mark the northern limit of the Phase 1B building.
