Site & Location
Located on the western corner at the end of the buildings that make up the continuous north side of Grosvenor Square where it joins North Audley Street. To the north, it faces Providence Court and it, therefore, has three street frontages. The fourth side of the building forms a rear elevation to an internal courtyard shared with two neighbouring residential buildings at 18 Grosvenor Square and 18 Providence Court.
