[1] Masey was a pupil of Bertie Crewe—with whom he worked on the Empire music hall in Edmonton of 1908—and from 1909, he went into partnership with architect Roy Young.
[1] Some of Masey's earliest designs include the Grade II listed New Wimbledon Theatre, built in 1919 together with Roy Young on the Broadway in Wimbledon, London, and the Electric Theatre in Bournemouth, built in 1919 for Alexander Bernstein.
[2] The Grade II listed Phoenix Theatre was designed together with Giles Gilbert Scott and Bertie Crewe, and opened in 1930.
Other buildings he was involved with include the Grade I listed Granada Cinema with four Corinthian style pillars over the entrance, located in Tooting, an area in the London Borough of Wandsworth, London, which opened in 1931 - one of the great, luxurious cinemas built in the 1930s; the 1932 Grade II listed cinema in Northfields Avenue, West Ealing, later used as a club and since converted into a church and the now-demolished Rex Cinema, 1936, in Station Approach, Hayes in the London Borough of Hillingdon, West London.
[4] He also designed the Grade II* listed Granada Cinema, Woolwich (with Reginald Uren and Theodore Komisarjevsky) and the Granada Theatre, Clapham Junction (with H. R. Horner and Leslie Norton), both built in 1937.
