Arnold House was a private boys preparatory school in Llanddulas, Conwy, north Wales,[1] known especially for its association with Evelyn Waugh.

[3] The founders were Reverend James Clement Collier Pipon (also the first headmaster) together with Susan Augusta Griffiths, his wife.

It was an independent preparatory boarding school for boys, intended for the sons of army/navy officers, businessmen, clergy, gentry, and the middle classes in general.

In the 1920s, pupil numbers increased and the school was divided into three boys' houses – Bingham's, Conwy's, and Pipon's – named after three alumni, all of who became Admirals in the Royal Navy.

[8][9] In his 1964 autobiography, two years before he died, Waugh confessed that he attempted suicide by drowning in the sea at Llanddulas during this period.
