He set up his studio at Runwick House, Hampshire in 1947, later moving to Bentley, Hampshire in 1948, at the pottery known as the Oast Pottery, where he was joined in the workshop by Paul Barron in 1954. Hammond attended the International Conference of Craftsmen at Dartington Hall in 1952 with Paul Barron. He had a two-man show with David Leach at the Casson Gallery, London in 1977.
