Miller was born in Radway in 1716. He was a British architect and a pioneer of Gothic revival architecture. He studied at St Mary Hall and Oxford.
Miller inherited Radway Grange when he was twenty-one and some years later, he started to redesign the Elizabethan house in a Gothic style.
He is especially known for the evocative mock "ruined" castles he created.
Miller died in 1780 in Radway.
