Border Archaeology Ltd (BA) has undertaken an Archaeological Desk-Based Assessment (ADBA) regarding the demolition of a modern chalet bungalow at No. 7 Sudbury Hill Close, Wembley, London HA0 2QR and erection of a three-storey residential building with associated car parking, soft and hard landscaping, cycle and waste storage. The overall archaeological potential of the site has been assessed in overall terms as Low to Moderate, with particular reference to encountering possible evidence of medieval occupation associated with the nearby hamlet of Sudbury and buried remains of outbuildings associated with Egremont Cottage and Aspen Lodge, two late 18th/early 19th century villas which were demolished in the mid-1950s. However, as the site of the new building will be located almost entirely within the footprint of the existing house, it is likely that any sub-surface features and deposits will already have been heavily disturbed by previous groundworks, thus reducing the likelihood of encountering significant archaeological remains.
