In his plan for Charlotte Square, Robert Adam designed a church for this site. Modelled after St Paul's Cathedral, it was to have an advanced portico with a pediment supported on coupled columns. Pavilions with pilasters on the corners would have flanked this arrangement while supporting small domes on peristyle drums. The central dome would have been similar, albeit shallower and with four pedimented faces on the drum. By the time of St George's construction, concerns over cost and the waning popularity of the Adam style meant a new design was sought from Robert Reid.Gray 1940, p. 123.
