Gradidge had the opportunity to work on a number of buildings in Surrey by prominent architects, such as Sir Edwin Lutyens, Harold Falkner, Hugh Thackeray Turner, Detmar Blow and Charles Voysey.
From there, they went onto Harold Falkner's Tancreds Ford, which they designed and built for the writer Ken Follett and his first wife, and which was published in two articles in Country Life.
[1] Next came Kingswood Hanger (The New House), reputedly designed by Hugh Thackeray Turner and for which they jointly won a RIBA Award, which was also published in Country Life.
Gradidge worked on a number of pub interiors for Ind Coope, such as the Markham Arms (now altered) on the Kings Road, Chelsea and the Three Greyhounds in Soho, London.
At St Marys, Bourne Street, South Kensington and the National Portrait Gallery in London, Gradidge carried out interior modifications, although they have since been altered.
A large man, who was gay,[4] Gradidge was an advocate of rational dress, a movement more usually associated with modernists, and had suits tailored in fine cloths that featured jackets and kilts.
