The tufo slab seems to be associated on the northern face of the northeast corner with SU 6292 which is a degraded linear stone feature that seems to extend underneath SU 6237. There is a similar looking feature on the west face of the southwestern corner of the slab, though as its full extent was not revealed due to SAR backfill and geotextile it was not given its own SU number. Only the top few centimeters of all three features have been excavated so the relationships and building techniques are unclear.
