[1] From 1901 to 1907 he worked for the London County Council before setting up in private practice.

He was appointed an Officer of the Order of the British Empire (OBE) in the 1919 Birthday Honours.

He was primarily a classicist; A. Stuart Gray wrote: "Some of his buildings suggest the influence of Sir Edwin Lutyens, but are bolder, balder, and less subtle or more frank depending on one's point of view.
