Trained in the offices of PARKER & FORSYTH in Cape Town where he was an assistant from 1910 to 1913, leaving to join the PUBLIC WORKS DEPARTMENT in Pretoria in October 1913. During the First World War he enlisted for service and for the duration of the war he served in the South African Motor Cycle Corps. He returned to work for the PWD after the war and sat the RIBA examination in Pretoria in May 1926. He was elected an Associate member of the RIBA in 1927.
Mullins was appointed Assistant Architect, PWD, in 1929. After W MOLLISON retired from the post of chief architect of the PWD in 1941 Mullins was appointed his successor.
A superb draughtsman, Mullins was responsible for many illustrations in Pearse's Eighteenth century architecture in South Africa (1933). He was also skilful in his handling of difficult situations and apparently contributed much to the smooth running of the work on South Africa House in London (1929-32) on behalf of the PWD. It is worth noting that his ARIBA nomination forms are remarkable for the beautiful writing and organised display of information (1927).
Among his best-known designs is the General Post Office in Jeppe Street in Johannesburg (1933-5). He registered as a member of the Institute of South African Architects in 1939.
