 On his appointment Christian moved his practice into the Commissioners premises in Whitehall Place, Westminster, later converting nearby stables into his offices when the Commissioners needed more space.Here Christian was to remain for the rest of his life and during this time, in addition to his building and restoration work, produced thousands of reports on designs for Church of England buildings that were submitted to the Ecclesiastical Commissioners for approval, completed surveys on the fabric of ancient churches including 14 cathedrals and assessed many architectural competitions, work which continued to within four days of his death at the age of 80.Christian's early work on churches in the 1840s had importantly led to the beginnings of this success.
