Roger Morris (19 April 1695 – 31 January 1749) was an English architect whose connection with Colen Campbell brought him to the attention of Henry Herbert, 9th Earl of Pembroke, with whom Morris collaborated on a long series of projects.
Born in London, Morris received thorough practical training as a bricklayer, as he was described in 1724, when he built a house for himself on the Harley estate in Oxford Street, London, but by 1730, in a larger house he built for himself in Green Street, he was described in the rates as a 'gentleman'. On his own account he was successfully involved in speculative building in London, which may have supported his position in life.
Professionally his career was closely bound at first with Sir Andrew Fountaine, a virtuoso and amateur architect, at Narford, and then to Colen Campbell, to whom he seems to have acted as assistant, as at Studley Royal in Yorkshire, and Lord Pembroke, one of the 'architect earls'. Lord Pembroke's connoisseurship combined with Morris's practical experience produced Marble Hill House (illustration, above right) for Henrietta Howard, Countess of Suffolk, 1724–29; the White Lodge, Richmond 1727-28; and, after Morris's tour to Italy with George Bubb Dodington (June 1731 - September 1732), Morris completed the interiors of Sir John Vanbrugh's incomplete Eastbury House, Dorset, for Dodington, 1733-38 (the house was exploded and razed in 1775); at a later date Morris designed and built a house at Hammersmith, near London, for Bubb Dodington (there a gallery was designed by Giovanni Niccolò Servandoni); the Column of Victory at Blenheim Palace (illustrated, left) for Marlborough's widow, Sarah, Duchess of Marlborough, 1730;Wimbledon House, 1732–33, also for the Duchess; the Palladian Bridge, Wilton House, 1736–37; and probably, Howard Colvin suggests, Westcombe House, Blackheath, near London, (ca 1730) which became Pembroke's own. Lord Pembroke presented Morris with a silver cup in 1734 as a token of his regard for him.
