Crickmay & Sons had its origins in an architectural firm established in Weymouth, Dorset, England in 1881 by George Rackstrow Crickmay (1831-1907) and his son George Lay Crickmay (1855-1921). By 1894 a second son, Harry William Crickmay(1861–1937) had become a partner in the practice which was renamed Crickmay & Sons.
In 1937 a later generation of the Crickmays, Colin Rosser Crickmay (1904-1999) and his cousin Hugh Waydelin Crickmay (1908-1978), took over the practice which was subsequently renamed C.R. & H.W. Crickmay & Sons.
Colin Rosser Crickmay retired from practice in 1972 and Hugh Waydelin Crickmay retired in 1977 at which point the practice may have closed.
