The fourth season of excavation by D G Bird for SCC and SyAS completed the plan of the 16th century brick building — a rectangle c 4 by 3 metres — and further examined the medieval ditches, whose purpose and plan remained unclear. (175)

Excavation by J A Janaway for the Godalming Group of SyAS produced only 19th century rubble and four medieval sherds in two trenches.

Excavation by the Bourne Society revealed medieval pottery, wall footings and a gravel surface, the first evidence for medieval Caterham. (See above, p. 123-33)

Excavation by R J Poulton for SCC and DoE in advance of redevelopment revealed Roman, medieval and post-medieval occupation. Of particular interest were several early pre-Flavian levels with evidence for round houses, a late 2nd or early 3rd century well or ritual shaft with the remains of at least 17 dogs, no evidence between late Roman and late 12th century levels, and a medieval well and ovens.

Excavation to the rear of No 43 by D W Williams for HAG located a well-preserved brick and stone built kiln, demolished c 1700, the lowest courses of a sub-circular stone well, backfilled in the 16th century, and part of a stone structure of the 13th or 14th century. The kiln was probably used for malting, and has been preserved beneath an access road to the new development. Observation and salvage on other parts of the site revealed near the main excavation a line of probably 14th century pottery water pipes, some 25 complete or nearly so and a lead sheet at one end of the line.

Excavation by Barbara Blatchford for Guildford Group of SyAS produced an early medieval arrowhead, a great deal of pottery, mostly 13th century, and various features including a levelled surface.

Roman and medieval pottery found in fieldwalking by the Guildford Group of SyAS.

Community excavation by SyAS and SCAU, under the direction of R Poulton, of the Scheduled moated site. Foundations belonging to the medieval manor, including part of the great hall, were uncovered, and coins recovered indicate that the site was established by the early 13th century. The property was later occupied by Lady Margaret Beaufort before her son, Henry VII, decided in 1503 to develop the site into a palace. Evidence of this period was revealed in the form of foundations of an oriel window of the new great hall, begun in 1508.

A magnetometry survey carried out in September 2009 by members of SyAS in a paddock referred to in the 18th and 19th centuries as Brickhill and Brick Kiln Field revealed strong, largely rectangular, anomalies. An initial test-pit down to the top of surviving archaeological layers suggested that the anomalies were due to areas much affected by heat. Later work in the following year suggested these were the remains of substantial rectangular brick clamps of probably medieval date.

A watching brief by T Munnery of SCAU, following the evaluation of the site in 1996 that revealed possible medieval features, did not reveal any further finds or features of archaeological interest.
