Described as a man '...of original mind and unstinted devotion to his art', his flourishing career was curtailed by the First World War and his untimely death at the age of 32 during the flu epidemic of 1918.

His early reputation was gained through the award of the Pugin Medal and a travelling studentship of the Architectural Association, and he established his own practice at Westminster in 1906.

[2] Rose's work appeared regularly in magazines such as The Builder and Country Life as well as in the architectural section of the exhibitions of the Royal Academy.

His houses included Woolmer Wood on Marlow Common, Buckinghamshire,[3] and Marrowells in Weybridge, Surrey, designed for Sir Vernon Kell.

[11] Algernon Rose was a very good rugby player and he captained Ealing from the 1907 season as well as playing representative matches for the Eastern Counties.
