text: Scott and his brothers were raised as Roman Catholics; their father was a Catholic convert. Giles attended Beaumont College on the recommendation of his father who admired the buildings of its preparatory school, the work of J. F. Bentley. In January 1899 Scott became an articled pupil in the office of Temple Moore, who had studied with Scott's father. From Moore, or Ellen Scott, or from his father's former assistant P. B. Freeman, Scott got to know the work of his father. In a 2005 study of Scott's work, John Thomas observes that Scott senior's "important church of St Agnes, Kennington (1874–77; 1880s–93) clearly influenced Giles's early work, including Liverpool Cathedral Lady Chapel."
  In later years Scott remarked to John Betjeman, "I always think that my father was a genius. … He was a far better architect than my grandfather and yet look at the reputations of the two men!" Scott's father and his grandfather had been exponents of High Victorian Gothic; Scott, when still a young man, saw the possibility of designing in Gothic without the profusion of detail that marked their work. He had an unusually free hand in working out his ideas, as Moore generally worked at home, leaving Freeman to run the office.
