Locus 2 is a level compacted plaster surface associated with OC2/Workshop. The plaster surface is well preserved within the extent of Locus 2, though the surface preserves many small cracks. Locus 2 extends for 0.99 meters from the western baulk wall and 2.30 m from the northern edge of the floor close to Locus 5. Locus 2 was extended in a 1.5 m by 3 extension of the trench and was found to continue around the cut of Locus 22 and the column base of Locus 18.

The floor ranges in thickness from 0.08 m to 0.12 m. The surface extends to the edge of Locus 5 and Locus 18, indicating that the OC2/Workshop column bases were put in place before the plaster surface was laid down.

The plaster surface is equal to Locus 4, and is cut by Locus 22. The cut forms a linear and a connected rectilinar space filled by Locus 3 and Locus 19. Further excavation is needed to clarify the function of the cuts with the floor. The cuts are potentially related to drainage necessitated by production.
