 Douglas practised for the whole of his career in a provincial county town, and most of his works were concentrated in Cheshire and North Wales, yet he "conducted a practice which achieved national renown".He was never a member of the Royal Institute of British Architects, but his works featured frequently in national publications, including "Building News", "The Builder", "The Architect", and "The British Architect", the last of which particularly praised many of his works.A number of Douglas's works were exhibited at the Royal Academy and appeared in "Academy Architecture".
