Dated to period 7 at the site (after c.AD 270 to later 3rd century), a building with deep, rubble-in-mortar footings and tessellated floors (CAT Building 193). The ground plan is given by the later (Period 10a) robber trenches, and is as follows: a line of three rooms, two of them wholly within the site and one running off the north edge; parallel with these rooms and on their east edge, three rooms running off the east edge of the site; off the west side of the first row of three rooms was an open area, probably a courtyard; and south of this were further, badly defined rooms. The mosaic found in the 1997 evaluation does not fit readily into this ground plan. Although it is more likely that it belonged to this period than any other, there is the possibility that it was earlier.

Very little of the floors survived, although small areas of irregular tile, tesserae and septaria chips in a mortar base including opus signinum were found. A tiny patch of plain red tessellated flooring survived in Room 9. Walls from this period only existed as fragments of wall footings of pale brown mortar with septaria lumps.<1>
