 Christian's employers no doubt expected him to carry out his restorations to a set standard which would include the removal of old box pews and galleries and the providing of new seating and furnishings, as in the architect's work at Christ Church, Spitalfields.He scrupulously kept within his employers' budget and was always concerned to meet the client's needs and requirements for a commission, as is clearly shown in his work for W. H. Alexander on the National Portrait Gallery, London.Christian was more than capable of producing outstanding architecture when the commission and the funding allowed him the opportunity, as at St Mark's Church in Leicester and at St Matthew's in Cheltenham and as his own house in Hampstead, London proves.
