The evaluation comprised the excavation and investigation of six trial trenches to the west of the Coton House stable buildings, in a former car park and adjacent areas. The remains of modern brick walls, a foundation trench and a brick-built conduit were revealed in the southern part of the site. These features are the remains of 19th-century glasshouses and ancillary buildings, which are shown in this location on the 1887 First Edition Ordnance Survey map of the area. There were no features or finds from periods predating the construction of Coton House in the late 18th century.
