During excavations at Culver Street between 1981-2 and 1984-5 (ECC337), a Roman building (CAT Building 127) was excavated. The building was situated along the north side of Insula 35 with its frontage onto an east-west street (MCC733). Its north wall was built on the south side of the street with the effect that the width of the street was reduced from about 9.0m to 6.5m.

This was a large aisled building of unusual construction. It had two wide external walls built on foundations about 1.5m across. The aisles were formed by two rows of columns or piers supported on foundations about 0.8m square. The building was at least 45m long x c.17m wide internally.

The foundations had been robbed but were constructed of a mixture of packed rubble and were built over wooden piles set into the underlying archaeological deposits. No floor levels or other layers survived having been removed by later cultivation of the site. The absence of internal features means that the function of the building is uncertain although a function as either an agricultural barn seems most likely.

Two inhumations lay under the north aisle (MCC1120 and MCC1121) and probably predated the robbing of the buildings foundations.<1>
