A watching brief was carried out during the groundworks for a rear extension to the property and for a swimming pool in the garden (CBC planning application F/COL/05/0244). Fifteen visits were made during the groundworks. The ground in a 22.4m x 11.9m area to the rear of (west of) no 7a was reduced, in the area of the extension. This was where the extension to the property was to be built. The ground was stepped down so that, at the rear of the property, the depth of reduction was between 750mm and 800mm, and to the west, by the boundary wall, it was 2.2m. Foundation trenches were subsequently dug up to 1.6m deeper. Up to 800mm of topsoil was observed which may well have been brought in from elsewhere. At the western part of the reduced area, natural was seen at 1.7m below ground-level. No archaeological remains were recorded. An area measuring 11.5m x 5.65m was excavated for the swimming pool. A 'pit-like feature containing a small amount of Roman brick' was defined within the area of the swimming pool.<1>
