During excavations at Culver Street between 1981-2 and 1984-5 (ECC337), a Roman timber-framed building (CAT Building 107) was examined. The building was mainly identified through distinctive gravel-packed pits 'which were a constructional feature of many of the buildings erected in Flavian Colchester'.

On average each pit was 0.6 to 0.9m square and up to 0.9m deep. Many formed rows where the pits were roughly spaced at 2.0 to 2.5m intervals. The west wall of the building was represented by a row of four pits and the frontage was defined by three pits. Two pits showed the likely position of the east wall and one the possible site of the rear wall although it is possible that the building continued beyond this.<1>
