In 2014 land on Gravelly Hill was purchased by Caterham School and they expressed an interest in knowing the archaeological and historical background to their new land. The late Peter Gray had already noted the presence of earthworks within the area but access had previously been limited. As a result of the change of ownership members of the Surrey Archaeological Society undertook aa measured survey of the land within the medieval park and a small area to its immediate north.
Monitoring by Z Pozorski of AS undertaken during floor level reduction within a timber-framed structure believed to be largely of 15th and 16th century date, with 19th and 20th century alterations, but the core of which is thought to be medieval. The monitoring revealed earlier floor layers, and the remains of a hearth constructed of peg tiles dated to the 15th and 17th centuries. Historic building recording undertaken by M Higgins of SCC during refurbishment and extension revealed the two earliest phases of its development to be c1425 and c1475.
Geophysical survey and standing remains recording by D Calow, A Hall and N Cowlard of SyAS. The geophysical survey was hampered by tree cover, but confirmed the existence of a second building to the east and suggested a series of hitherto unknown anomalies that might represent ditches, as well as indicating that demolition deposits could extend over a considerable area.
Historic building assessment by M Higgins of SCC of the small L-shaped two-storey dwelling with an attached single-storey agricultural building.
Historic building assessment by M Higgins of SCC of what was once a stable with hayloft above and of probable 18th century date.
Historic building assessment by M Higgins of SCC of the possibly late 16th century building.
Evaluation by K Grant of ASE revealed evidence of previous truncation across the site, but no finds or features of archaeological interest related to either medieval backland or other activity.
Historic building assessment by M Higgins of SCC of the timber-framed half-Wealden open-hall house of 15th century date.
Historic building assessment by M Higgins of SCC of a double-ended two open-bay open-hall house, now divided into two dwellings, and which probably dates to the third quarter of the 15th century.
Evaluation by D Hopkinson of ASE revealed a wall foundation and two postholes of post-medieval date thought to relate to the property currently on the site.
