Abstract The abstract describing the content of the publication or report Abstract:	In January 2018 Compass Archaeology undertook a program of archaeological monitoring on the site of Nos.22 Grosvenor Square, 43 North Audley Street and No.1 Lees Place, in the City of Westminster, London, W1K 6DT. The monitoring exercise followed on from an archaeological Desk-based Assessment, (DBA), attached to the original planning submission for extension of the existing basements at 22 Grosvenor Square, 43 North Audley Street and 1 Lees Place. The DBA concluded that due to the site's location within an Archaeological Priority Area, the potential for locally significant 18th century remains, and in light of the total loss of any potential archaeological remains through the excavation of the extended lower ground floor and new basement, some form of archaeological mitigation would be necessary. This led to the archaeological monitoring of geotechnical investigations on site. This involved the monitoring of 12 hand dug test pits within the footprint of the proposed development and the interpretation of 4 boreholes and 7 window samples sunk into the underlying geology. The majority of the test pits contained deep made-ground deposits with no archaeological survival. However test pits 1, 10, 11 and 12 all produced structural remains from previous developments on site dating from the early-18th century to the early 20th century. Test pit 12 also produced a single residual mid-4th century Roman coin. The boreholes and window samples all reached natural geology at depths of between 1.20m to 3.00m below present day ground levels, which indicated a high level of below ground disturbance and truncation across the site.
