Professionally, his career was closely bound at first with Sir Andrew Fountaine, a virtuoso and amateur architect, at Narford, Norfolk; and then to Colen Campbell, to whom he seems to have acted as assistant, as at Studley Royal in Yorkshire;[4] and Lord Pembroke, one of the 'architect earls'.
[13] John Harris has demonstrated that Morris made a design for the Porter's Lodge at Wilton House, ca.
[15] Morris's ability and the recommendations of his well-placed patrons secured him a post in the Office of Works, from which all designs for the Crown emanated.
In 1734 he succeeded in the post of Master Carpenter to the Office of Ordnance,[16] which was worth £2-3,000 a year, for works at the Royal Arsenal, Woolwich and elsewhere.
[19] Morris's independent designs have been praised for their innovatory approach, the architectural historian John Harris writing: "his villas, for example, were, and are, strikingly original in contrast to Campbell's, while Carné's Seat at Goodwood characterises the individual style Morris bestowed upon temple buildings".
