(b. 1716, Radway, d. 1780, Radway)
English architect and landscape designer. He was born, lived and died at Radway, on the Warwickshire estate bought by his father in 1712.
At the age of 15, Miller was already interested in antiquarian subjects, and while studying at St Mary Hall, Oxford he continued to develop his interest in England's past, under the influence of William King. He inherited Radway Grange when he was 21, and a few years later started to redesign the Elizabethan house in a Gothic style. In the grounds he added a thatched cottage and octagonal tower based on Guy's Tower at Warwick Castle.
This work at Radway established Miller's reputation as a gentleman, or amateur, architect and landscape designer. His wide social circle, and contacts developed through his patron George Lyttelton, 1st Baron Lyttelton, led to many requests for his designs. He produced some classical buildings like the Shire Hall in Warwick and Hagley Hall, Worcestershire, but is more often associated with Gothic Revival work, as at Albury Hall, Oxfordshire and the Great Hall at Lacock Abbey. He is especially known for the evocative mock "ruined" castles he created at Hagley, Wimpole Hall and Ingestre Hall, Staffordshire though this last has since been demolished. Other places to which he contributed include Wroxton Abbey, Upton House Sham Castle and Siston Court and Tudor Court, Hanworth Park, the surviving part of a Royal hunting lodge used by Henry VIII.
Miller is regarded as an English pioneer of Gothic Revival architecture. He is mainly noted for adding picturesque garden buildings and features to the grounds of an estate.
