Under Principal Railway Architect John Sidney Egan, new station designs were prepared for the quadruplication project. An overall concept for the form and structure of the station buildings was established, but the designs were non-standardised, and took account of platform width, which varied from station to station. Architect Jan Kral was responsible for the Graceville and Chelmer designs and signed off on the drawings for Sherwood station as Acting Principal Architect. He was born in Poland and studied at Stuttgart University after the war. He came to Australia in 1950 and was employed by the Queensland Railways the following year, initially as a draftsman, becoming a Senior Architect by 1958. While the designs were all somewhat different, they shared a form derived from a long, thin building, rectangular in plan and made with a regular procession of columns, surmounted by a butterfly roof that cantilevered over each platform side to shelter waiting and alighting rail passengers. A number of standardised plans for Railways Department butterfly-roofed awnings were developed and used between 1949 and 1960, many having been designed by Bevis Thelwall. A common palette of materials including reinforced concrete, steel and exposed brickwork was used. The steel work was all prefabricated at the Northgate workshops. Graceville Station was the first of these station fit-outs to be completed within the quadruplication project between Corinda and Roma Street.
