He was an illustrator and also worked in stained glass and mosaic, making many of his design at the Glass House, Fulham. His bas-reliefs in coloured plaster are best represented by the interior decorations at Le Bois de Moutiers, a house in Varengeville, Normandy, designed by Edwin Lutyens in 1898. He was also responsible for executing the decorative friezes designed by Charles Rennie Mackintosh for Miss Cranston's Buchanan Street tea rooms in Glasgow. Bell's appreciation of early Italian art forms the basis of his work in mosaic, a medium he used to great effect in other public commissions in London including the Horniman Museum. He was an active member, and in 1921 Master, of the Art Workers' Guild, as well as a member of the Arts and Crafts Exhibition Society, helping to organize the latter's shows in London, Turin, Brussels and Paris. He was an instructor in painting and design at University College, Liverpool in 1894 and head of design at Glasgow School of Art from 1911, and Professor of Design at the Royal College of Art, London, from 1918 to 1924. His wife, Laura Richard-Troncy, a pupil of Alphonse Legros, assisted him with gesso-work and gilding. Examples of his work are in the collections the Walker Art Gallery, Liverpool, Manchester City Art Gallery, the Tate Gallery and in art galleries in Australia.
