Report by P Wakefield on a rapid survey of this complex, which includes the water works and electricity generating station for the hospitals of the former Horton Manor estate. The buildings date from 1901 and were designed by W Clifford Smith, engineer to the London County Council Asylums Committee. The boiler house has suffered a change of use that involved the loss of its chimney, but the water works and generator hall survive relatively intact, albeit derelict. A disused reservoir probably served the original steam boilers.

Evaluation by J Saunders of TVAS, for the South Thames Regional Health Authority, in advance of redevelopment. No sign of the expected moat around the manor was revealed, but two hollows containing late Bronze Age/early Iron Age pottery were identified. A subsequent small scale excavation revealed a further pit also containing pottery of that date, but no other related features. (310) see report in SyAC 87, 175-178.

Survey of the archaeological and historic landscape of the Commons by C Currie of CKC Archaeology, for SCC and the Corporation of London, undertaken with reference to them being proposed as Areas of Historic Landscape Value. In the north of Ashtead Common a number of earthworks and other features surround the site of a Roman villa. The villa is a rare type of corridor villa, with considerable evidence that it adjoined a large scale tile manufactory. Extensive areas of quarries and spoil heaps demonstrate the extent of industrial activity on the site in the Roman period.

Evaluation by M Dover of SCAU, for the Mitchell Evans Partnership, of the site of a new leisure centre within what was formerly Nonsuch Park. Several features were revealed, some of Roman date, some possibly Bronze Age. Only the bases of these features survived, indicating that the use of the site as a nursery had caused a degree of disturbance.

Watching brief carried out by N Shaikhley of SCAU for Nonsuch High School revealed no significant finds or features; the area was found to have been disturbed previously.

Evaluation by J Robertson of SCAU, for the Surrey Community Development Trust, in advance of residential development revealed no features, and only three fragments of post-medieval tile and a possible struck flint flake. No signs were encountered of Stane Street, previously thought to cross the site, and the possibility of an alternative route for the road in this vicinity now needs to be considered.

Evaluation by G Hayman of SCAU, on behalf of McCarthy and Stone Ltd, in advance of development for sheltered accomodation. Four trenches revealed no finds or features of archaeological interest.

Watching brief by G Pattison of SCAU, for Glencarron Properties Ltd, of redevelopment within the historic centre of Epsom revealed that the site had previously been extensively disturbed; no archaeological levels survived.

A watching brief was maintained by J Stevenson of SCAU, for Epsom and Ewell Borough Council, during the construction of a new access road and car park for the Town Hall in Epsom. A post hole of possible medieval date was found, as well as chalk block foundations with remnants of the original mortared flint walling and associated mortared tile floor. Historical references show a cottage and barn on the site in 1680, which became known as Cromwell House in the 18th century. It seems likely that the remains encountered form part of the earliest phase of this building.

Watching brief carried out by G Pattison of SCAU on behalf of Victory Investments Ltd. The site was found to have been comprehensively disturbed to a depth of 1.4m in the 19th and 20th centuries, with no finds or features of archaeological interest being recorded.
