During excavations at Culver Street between 1981-2 and 1984-5 (ECC337), a large Roman building (CAT Building 120) was discovered situated in the south-east corner of Insula 34. The building was a Roman house of the winged corridor-type. The main part of the building was on the plot occupied by the earlier barrack building (MCC759) with the two wings being an encroachment onto the adjacent property to the north. The shape of the house had been influenced by its predecessors MCC905 and MCC916.
Almost the entire house was available for excavation although most of the wall foundations had been robbed out in the early medieval period. The building included thirteen rooms, up to four passages and a gravelled yard area.
The floors present varied from simple ones constructed from sandy clay, to two of opus signinum (both of which had quarter-round mouldings), one wooden example, seven with red tessellated pavements, two with mosaics and one with a hypocaust.
Internal features included hearths, a pit containing burnt fodder and one room had a stake hole for the hypocaust. Between the two wings of the building was a gravelled yard in which was a tiled tank, presumably for holding water or some other liquid.<1>
