Mountford is seen as one of the initiators of the Wrenaissance style of Baroque Revival architecture which characterises many British and Empire public buildings during the Edwardian era; Edwin Lutyens was a fellow exponent of the style – and Mountford and Lutyens had a form of connection via their work in Munstead Heath, where Lutyens designed Munstead Wood for Gertrude Jekyll and Mountford build Munstead Grange – Jekyll advising on his garden design – as his country house. Mountford was awarded a silver medal at the Exposition Universelle (1900) for his Edwardian baroque designs. His domestic architecture, however, appears to have been influenced by the architecture of his Gloucestershire, Somerset and Warwickshire youth.
