During excavations at Culver Street between 1981-2 and 1984-5 (ECC337), a large Roman building was excavated. The building was situated along the northern edge of Insula 35, south of an east-west street (MCC733) and to the east of a large house (MCC923).
Most of the foundations of the building had been robbed in the early medieval period and the latest levels associated with the building had been destroyed during early medieval cultivation. The two foundations which survived were constructed of mortar and septaria rubble poured into a trench.

The building consisted of a range of five rooms with a corridor to the south and a corridor or veranda to the north. The floors of the rooms were all of sandy clay except for one which had a mosaic pavement with a plain red tessellated border. Structural features within some of the rooms pointed to the possibility of the building having had a hypocaust.

The buildings southern passage had a tessellated floor whilst the northern one appeared to have originally been continuous with a passage in an adjacent building (MCC923) to form a covered public footway (MCC1076) or veranda along the side of the street (MCC733). This passage was later blocked by a north-south wall and may have been converted into two separate rooms.<1>
