Round house 1 was represented by a curving section of ditch 8.15m in length and some 0.6m wide by 0.19m deep. Its fill was a sterile clay silt, indicative of natural erosion. Projection of this feature to form a full circle suggests that it may originally have possessed a diameter of some 12m. this suggests that the round house was fairly large, approximately 10m. This allows for a 1m berm between the non-archaeologically defined outer building wall and the drip-gully. It is notable that middle Iron Age roundhouses of the Thames Valley and East Midlands are generally defined by pen-annular drip gullies or fragments of such gullies, rather than post-holes It was located on Plateau 9, 36m immediately to the west of Feature cluster 2. Round house 2 lay approximately 11.25 metres to the south-east of Round-house 1. The ditch was again relatively shallow, only 0.19m deep by 0.23m wide, and had been mostly removed by a combination of later features and horizontal truncation. A total diameter for the feature is estimated to have been no more than 7.7m. As with Round-house 1, the silty nature of the fill contained in this feature is thought to have a natural origin. If this feature represents the drip-gully a small circular structure of c 5.7m diameter may be represented. Whether the Thanet Earth examples do indeed represent true round-houses remains debatable, due to the level of truncation. (1)(information summarised from source)
