Planning permission (3/16/0594/FUL) was granted by East Herts Council for development at Glen Leigh House, Levens Green comprising the demolition of the existing house and garage and the erection of a two-storey replacement dwelling with basement. The consented site lies within Area of Archaeological Significance no. 340 (as identified in the Local Plan) and its known archaeological potential was described in the heritage assessment submitted with the application (Albion Archaeology 2016). As the development had the potential to impact on below-ground archaeological remains, Hertfordshire County Council's Historic Environment Advisor recommended that a programme Archaeological Strip, Map and Record, Analysis, Publication and Archiving should be undertaken. The work was undertaken by Albion Archaeology between 10th July and 24th October 2017 in accordance with an approved Written Scheme of Investigation. The site is located in the small hamlet of Levens Green in the parish of Great Munden, within the district of East Hertfordshire. It lies on a gentle south-facing slope at an elevation of c. 120m OD and is centred on grid reference TL 3579 2229. It was formerly occupied by a detached 1960s bungalow. The investigation revealed that the construction of the new dwelling was largely confined to ground that had previously been disturbed by the construction of the former property and its subsequent demolition. Where undisturbed natural geology survived, there was no evidence of archaeological features or deposits earlier than 20th-century in origin.
