classes. Responding to increasing apprenticeship enrolments a further three-storey extension, R Block, was constructed in 1928 accommodating the Industrial High School. Later infill linked R and K Blocks. W Block, a four-storey addition to the J Block Workshops completed in 1956, though planned forty years after the original Brisbane Central Technical College buildings is similar in materials and expression. In addition to the Workshop extensions other additions and alterations have occurred to the Brisbane Central Technical College. S Block, erected adjacent to F Block in 1921 as a College store and later incorporated into F Block, is now demolished. An additional storey was added to A Block to accommodate Art, Architecture and Building in about 1924. Throughout the 1920s enrolments at both the University of Queensland and the Brisbane Central Technical College steadily increased. Although plans were underway to transfer to the St Lucia campus, a building was constructed to commemorate the 25th anniversary of the foundation of the University and was shared by both institutions. The building accommodated the Library of the University and various facilities for the Technical College. An imposing three-storey facebrick building in a restrained neo-Georgian idiom, the Library faced the Main Drive between Old Government House and the Art School (C Block, demolished 1978-79). Although altered and extended over the years, the Brisbane Central Technical College represents an important era in education in Queensland and is the most extensive group of technical college buildings of the period. A major undertaking for the Queensland Government, the construction of the Brisbane Central Technical College was the largest building project for the Department of Public Works immediately prior to World War I. The architectural work of the Department of Public Works in the first decades of the twentieth century was of a high quality with many talented architects working in the office including Thomas Pye, Charles McLay, John Smith Murdoch, George Payne and Andrew Irving. Alfred Barton Brady was Government Architect and Thomas Pye, Deputy Government Architect. Brady administered the office and supervision of design was carried out by Pye. Pye was the driving force in developing and maintaining the office style after 1906 following the departure of Murdoch. Responsibility for individual projects within the Department was seldom clear-cut but evidence in the departmental files suggests that Pye had a major influence on the design of the Brisbane Central Technical College. The Department was responsible for the plans,
