The latest excavation campaign investigated two rooms, 15 and 16, situated in the NE part of domus 17-20. The aim was to check the existence of polygonal wall built of tufa that had been tracked two years earlier and functioned as a dividing wall between one room in this building and another in the adjacent structure (VI 2, 18-19).

Room 15 revealed a floor, but no dating elements, however it can be hypothesised that it dates to the 3rd century B.C. A plastered wall rested on top of this floor, which together with the polygonal wall delimited a small space and a room on the other side. Subsequently, in the latter the floor level was raised and the beaten earth replaced with an opus signinum floor. Sometime later the plastered wall was razed to the ground and a latrine was built, probably around the second half of the 2nd century B.C. (reuse of Maña C type amphora).

In room 16, next to the preceding one, a razed wall was found aligned with the polygonal wall. Originally (second half of the 2nd century B.C.), to the north it delimited a small room belonging to domus VI 2, 18-19 which was later annexed to the adjacent property. In room 16 evidence was found of occupation levels with crushed lava floors probably relating to some craft-working activity. Subsequently, in the Imperial period, the room had an opus signinum floor with decorative motifs in limestone and lava tesserae. Later, perhaps still in the post-earthquake period, the room was used for an activity involving the use of liquids, as attested by the presence of a small tank in one corner.

The latest evidence of activity on the site was provided by a large midden in the centre of the room.
