Watching brief by C Turner of HN. No evidence of activity prior to the 19th century was observed and the site appeared to have been extensively disturbed, although an unexcavated area of garden to the west appeared to be undisturbed.
Watching brief and historic building recording by A Taylor and G Elliot of TVAS. Coombe Edge was noted as a good example of a small country house with a lodge and for its association with the family of Sir Ranulf Fiennes. Groundworks associated with a new house, pool and pond were monitored for remains connected with the route of the Roman road thought to run adjacent to the site, but no finds or features of archaeological interest were revealed.
Evaluation by N Randall of SCAU recorded an undated pit, possibly an earth oven, and two unstratified flint cores of Mesolithic or Neolithic date. Across the centre of the site were large areas of ground disturbance that probably related to the 20th century use of the site as military barracks, and the impact of a railway line that traversed the site during the inter-war period.
Building recording by Boyer Planning following a fire recorded architectural features of the early 19th century building.
Evaluation by A Foard-Colby of NA (Northamptonshire Archaeology). A relatively modern peat deposit with upper horizons dating to the 20th century was revealed, together with a modern field boundary apparently backfilled in the 1970s.
Historic building survey by T Davies of WEED (Waterman Energy, Environment and Design Ltd). Both buildings were constructed in the period 1912–14 in the Arts and Crafts style. A number of features typical of the period, including an asymmetrical plan, extensive use of local materials and an idiosyncratic design that attempted to mimic the landscape as well as demonstrate piecemeal development, were noted. Many original internal features also survived and were recorded.
First phase of an evaluation by J McNicoll-Norbury of TVAS. No finds or features of archaeological interest were revealed.
Evaluation by D Millbank of TVAS. No finds or features of archaeological significance were revealed.
Detailed survey (1976) of barrow group and examination of trench cutting surrounding ditch by S.P. Needham and D.M. Longley for SyAS and DOE.
Two trial excavations by G H Cole in advance of redevelopment produced Mesolithic cores and flakes, medieval and post-medieval pottery but no structures. A stratified sequence of c 50 clay pipe bowls from the early 17th to the mid-19th centuries was recovered. (182)
