transport house, formerly railway house, was designed by henry budden & mackay and completed in 1936. the building caused enormous controversy through the use of day labour in its construction but the aesthetics and design were well received. it was described as being colourful without being vulgar, and modern without being extreme. the building was designed to accommodate all the various offices of the railway department and included the commissioner's suite and the "trouble room". externally the building was faced with trachyte at the ground level and above with green toned terracotta tiles; green was the colour for the railways. windows were set in bronze features, including wrought iron balustrading and metal window louvres. these were produced by the department's chullora railway workshops. the building won the sir john sulman medal in 1935 and the royal institute of british architects medal in 1939. the interiors have been progressively adapted since its construction, particularly the lift and entrance lobbies. the most substantial impact has been in the demolition of the northern wall to permit access to the adjoining building.
