Castlemaine Perkins Building, Heritage-listed brewery building in Brisbane, Australia.

The Castlemaine Perkins Building at 418–420 Adelaide Street is a two- and three-storeyed brick warehouse, bond store and office building designed by Thomas Ramsay Hall. Hall incorporated an earlier two-storeyed stone warehouse of about 1900, built for the quarrymen George Bowser & Co., into the new structure. A bulk store was added at the rear in 1928–1929.

Built between 1918 and 1919, this structure served as the headquarters of Castlemaine Brewery, a major producer of beer in Queensland during the early 20th century. The building reflects the industrial growth that Brisbane experienced after World War I.

The building displays craftsmanship typical of early Brisbane industrial design, with grape and vine motifs on its facade that reflect the brewery's purpose. These decorative details show how factory structures of that era were built to be visually appealing, not purely functional.

The building is located on Adelaide Street in Brisbane's city center and is easily accessible for viewing from the street. The well-maintained structure is clearly visible from ground level, making it straightforward to observe the architectural details.

The stone foundation was engineered specifically to support additional floors, demonstrating early 20th-century forward-thinking construction methods that allowed the building to accommodate future growth. This structural planning shows how architects anticipated the brewery's expanding operations.
