Evaluation and subsequent excavation and watching brief by G Hayman of SCAU on the site of the proposed bicentenary glasshouse. A number of ditches were revealed during the evaluation. Dating evidence was slight, but the subsequent excavation and watching brief that followed established that the area was subject to two distinct periods of landscape management, with enclosure ditches and field systems dating to the Middle–Late Bronze Age and to the 11th–12th centuries. The flint assemblage was predominantly Bronze Age, with a small number of Mesolithic and Neolithic pieces also collected.

Watching brief by N Shaikhley of SCAU during the excavation of a cable trench. No finds or features of archaeological interest were revealed in an area that had been the subject of relatively modern disturbance.

Watching brief by C Currie of CKCA during the excavations for a lift shaft revealed possible evidence for the foundation wall of either 16th or 18th century houses, both formerly on the site, and a drainage channel. The investigation was however too limited in scale to provide conclusive dating evidence for any features.

Observation of groundworks undertaken during road improvements by N Shaikhley of SCAU. No finds or features of archaeological interest were noted, although the work was conducted at a late stage in construction operations and any archaeology present on the site may already have been removed

Monitoring of geotechnical test pitting by G Priestly-Bell of ASE. No features were recorded, but the quantities of burnt and worked flint contained within the topsoil were thought to be suggestive of prehistoric activity in the area.

Evaluation by A Haslam of PCA revealed no finds or features of archaeological interest.

Evaluation by R Poulton of SCAU revealed no finds or features of archaeological interest.

Evaluation by R Poulton of SCAU revealed no finds or features of archaeological interest.

Evaluation by M Collings of ASE revealed no finds or features of archaeological interest.

Evaluation by T Malim of GAP encountered extensive remains of 19th century structures relating to gunpowder manufacture on the site, although little evidence for earlier activity was observed
