faces the Main Drive and is a landmark building at the main entrance gate to the campus. E, F, G and H blocks are grouped around the courtyard. J Block and extensions form a visual and physical close to the courtyard and are on the alignment of the roadway to the rear of the campus. U Block extends down the Main Drive preserving the alignment of the original master plan along this roadway. Blocks A, E, F, G, H and J are unified in their general elevational treatment, materials and detailing. All are red facebrick with contrasting features in dark red brick including relieved quoining, arched entrance porches, flat arched window heads and banding to floor levels. The original building department name appeared in metal lettering in an Art Nouveau style within a carved stone tablet above the entrance porch to each building. Only "Chemistry" on the east entrance to E Block survives. The central courtyard formed by the building group is a compact light, airy space. The pathways between the buildings provide visual and physical links with the courtyard and with the other buildings. The position of building entrances and corridors indicate the proposed circulation patterns that connect the buildings as a group. The buildings, courtyard and surviving paths between the buildings of the former Brisbane Central Technical College precinct are of cultural heritage significance.

A and C Blocks were almost mirror images and flanked the main building of the College, B Block. A Block was opened in 1915 as the Commercial and Day School and an additional storey following a similar plan to the earlier work was constructed in about 1924 to accommodate increasing enrolments. The Commercial High School was also accommodated in the building from 1933. The building interior has been altered, particularly during the refurbishment of 1996-1998, but the building form and exterior remain. Recent work has established walkway links envisaged in the original master plan. A Block now links with F Block at ground and first floor levels through the connecting gangways and passageways of the
