John Mills Himself Building, Historic warehouse in Brisbane City, Australia.

The John Mills Himself Building is a face-brick and render warehouse at 40 Charlotte Street, Brisbane, built in 1919. Its three-storey street front has a tall parapet with a triangular pediment bearing the raised lettering "John Mills Himself", and a band of blue ceramic tiles runs between the first and second floors. A two-storey rear building faces a laneway from Elizabeth Street, and the two are joined by an open timber stairway over a shared basement.

John Charles Mills bought this Charlotte Street site in July 1918 and built his office, printery and warehouse here in 1919, on land earlier occupied by Markwell's cottage. His firm, trading as John Mills Himself, had begun as Mills and Green in Adelaide Street in 1907–1908. In the 1920s he leased rooms to the Gresham Publishing Company (1920–1933) and the Press Etching Company (1921–1941); after his death in 1934 his sons John and Sam continued the business, and the property stayed in the Mills family until the 1980s.

The name comes from John Mills, who traded alone as "John Mills Himself" after dissolving his partnership with Green. His printing and stationery business attracted clients such as author Steele Rudd, and he leased spare rooms to the Gresham Publishing Company, the Press Etching Company, and to clothing manufacturers, mapmakers, watchmakers and lantern slide makers.

The building sits at Charlotte Street in Brisbane and is accessible by public transport and on foot from nearby areas. Visitors should note that as a heritage site, it is best appreciated from the exterior and can be viewed throughout the day from the street.

The raised lettering "John Mills Himself" sits in the tall parapet below a triangular pediment, framed by brick pilasters that continue through the parapet as freestanding columns. The building is the tallest of a group of brick structures stretching from the Pancake Manor to George Weston and Sons.
