Marcus Barlow (1890–1954) was a prominent Australian architect in the interwar period, who designed a number of notable central city buildings in his home-town of Melbourne. He is best known for the 1932 Manchester Unity Building, whose Gothic corner spire dominates the major intersection of the city. Professional life Marcus Barlow was born in 1890 in Melbourne. It is not known where he gained his training, and first appears as a partner in the firm of Grainger Barlow & Little in 1917. Grainger and Little were late career architects with a long history of substantial designs to their names, and wide professional networks, which no doubt helped Barlow in his later career. In 1922 FGB Hawkins became a partner, and in 1924 they left to form Barlow & Hawkins, until Barlow left to head his own firm in 1927. A vital moment of his career was being appointed by the trustees of the Howey Estate, owners of about a quarter of a city block since the first land sales in 1837, to design the 12 storey Howey Court (demolished in about 1989); Barlow went on to design three other buildings in the estate, the Manchester Unity, the Presgrave Building and the Century Building over the next decade. Barlow managed to maintain a thirty-strong team during the economic turmoil of the Great Depression, no doubt largely due to the construction on the estate. Barlow was an enthusiastic adopter of the latest overseas styles and trends, advocating for instance for car-parking structures in the 1920s, the scrapping of the 132 ft height limit to allow for skyscrapers, and installation of air-conditioning. He was innovative on a domestic level as well, as seen in his Strawbale Home Building, in which he used straw bales as a more economical alternative to brick construction. He also had a strong social consciousness and public interest. He was also part of Oswald Barnett’s Slum Study Group (1934), Housing Investigation and Slum Abolition Board (1936). These endeavors led to him becoming the first consulting architect appointed by the Housing Commission in Victoria in 1937. He continued to practice after WWII, but 'his best days were behind him', and he died in 1954. Notable projects The following projects are all on the State Government's Victorian Heritage Register.
