Evaluation by T Munnery of SCAU revealed a single pit of possible medieval date. Evidence that the site had been severely truncated by previous development was recorded, suggesting little remaining archaeological potential.

Evaluation by T Munnery of SCAU revealed residual Mesolithic and Neolithic flintwork, a number of probable Late Bronze Age/Early Iron Age ditches and medieval or post-medieval quarry/dene holes. The character of the ditches suggests they form part of a field system rather than a settlement enclosure.
Evaluation by W Weller of the SCAU, adjacent to the Scheduled villa excavated by A W G Lowther, recovered large floor or wall tiles, samian pottery and a mortarium of Gaulish origin from subsoils and spoil heaps. A small number of pits and postholes, of probable1st–4th century date were revealed.
Watching brief by W Weller of SCAU did not reveal any finds or features of archaeological interest.
Watching brief by W Weller of SCAU revealed evidence of settlement activity from the Late Bronze Age to the Late Roman period, including a storage pit of a 1st century AD date and possible boundary ditches that may relate to the Romano-British settlement sites excavated in the 1930s to the south of the school.
Evaluation by T Munnery of SCAU. Medieval features comprising pits, postholes, a well and a possible buried soil were revealed. Two of the features and the buried soil may be as early as the late 12th or early 13th century. A relatively large number of struck flints, mostly of Mesolithic but also Neolithic date were recovered, mostly from one location in a limited-sized test pit. Sherds of Roman and Saxon pottery recovered are likely to be residual and unlikely to indicate that significant evidence from these periods is present on the site.
Evaluation by N Randall of SCAU revealed no finds or features of archaeological interest.
A watching brief by G Pattison of SCAU recorded an exposure of part of a wall that was formerly part of Guildford Castle. The wall is interpreted as being the top of the north wall of a first-floor solar erected in 1256 over the gatehouse.
Evaluation by T Munnery of SCAU. Two postholes and a linear feature were revealed. It was concluded that they were unlikely to be associated with settlement or occupation activity, and were almost certainly post-medieval, perhaps even as late as the 19th century.
Evaluation by P Jones of SCAU. No finds or features of archaeological significance were revealed.
