It is possible that walls 6133, 6134, 6136, 6137, and 6245 formed the original boundaries of a space with an entrance between 6136 and 6134 and a floor composed of half cocciopesto (now extant in 6146) and half mosaic (evidenced by 6172 and 6246). 6137 appears to have been truncated during the reorganization of space that involved the construction of walls 6139, 6140, 6171, and 6131, creating the current eastern limit of room G14. Wall 6139 appears to plug a gap between the truncated end of 6317 and the line on which wall 6140 was being constructed.

Built alongside SU 6131 to reduce the space and create room G-14.
