Sulman published his plan for a Federal capital city in his book "The Federal Capital" in 1908. However, his plan was apparently not entered in the Federal Capital Competition; it was certainly not shortlisted. Sulman became formally involved in the Federal Capital, Canberra in 1921 when he was appointed head of the Federal Capital Advisory Committee. Sulman's alterations to the Griffin plan made the city less like the one Griffin had planned and more in line with some designs aligned with the English garden city movement.
