A Roman timber building discovered during excavations at 5 Balkerne Gardens in 1965 (ECC659). The building was represented by a line of massive post pits, 25ft. apart and two feet in diameter. A similar posthole was found parallel to and 22ft. north of the first and eighteen inches north of this was a timber lined gully which the excavator interpreted as an eaves drip. The southern line of post holes was thought to represent an internal wall. The building had a clay floor which had been renewed once.

As it produced little evidence of domestic occupation, the building was interpreted as a barn or warehouse which was ultimately destroyed by fire resulting in the carbonisation of the timber in the gully and one of the posts in the post pits, together with a thick spread of burnt daub across the whole site. Pottery sealed by the destruction layer indicated that the fire could not have pre-dated AD. 160 'and may well have been considerably later'.<1>
