During excavations carried out by the Museum of London Archaeology ahead of development at Swanscombe Community School, a semi circular feature was uncovered. It was located to the south west of the Roman enclosure and was 5m in diameter. The function of this feature is not certain but it may have been an eaves drip gully for a roundhouse though there was no sign of any associated post holes or hearths (these may have been truncated). Roundhouses are known to have continued into the Romano-british period, particularly at rural locations such as this, and they normally date to the second and third centuries AD which would make this possible example contemporary with the walled enclosure, and it is possible that the roundhouse may have been used for some ancillary function (such as storage). Nine sherds of Roman pottery were recovered from within the fill of the gully, these date to between AD 170 and AD 300. A nearby pit which contained a burnt fill may be associated with this feature.
