In July 2011 Oxford Archaeology (OA) conducted an archaeological field evaluation at Culham Court, Remenham, Berkshire. The work was commissioned by Symm and Company Ltd, on behalf of the owners, as a result of planning conditions attached to a proposed basement extension to the house. The current evaluation, situated to the west of the house, consisting of a single 14 x 1.8m evaluation trench, revealed a substantial undated NE-SW aligned ditch and a possible pit containing a single fragment of 19th-20th century window glass and interpreted as the remains of a former landscaping feature. An abraded, fragment of late Iron Age - early Roman grog tempered pottery was recovered from the topsoil of the evaluation trench. As a result of the findings of the evaluation, Mary Neale of Berkshire Archaeology requested a watching brief to be conducted during the initial construction phase of the basement. The watching brief revealed several postmedieval archaeological features within the area in addition to the ditch discovered during the evaluation. The results of the watching brief demonstrated that the substantial ditch, interpreted as a boundary ditch, was stratigraphically the earliest feature encountered within the area. The remaining features consisted of two mid-late 19th century shallow ditches, one associated with the existing yew tree hedge, a curvilinear ditch encircling a tree stump interpreted as a garden feature, two discrete features, probably the remains of tree boles and a curvilinear ditch filled with loose chalk rubble, probably the remains of the 19th century ovoid path encircling the terrace immediately to the north of the house and removed in the 1960s.
