transport house is a twelve-storey steel frame office building above wynyard railway station, designed by h. e. budden & mackey in the inter-war art deco style. the framed structure supports a broad, asymmetrically facade, with horizontal bands of large bronze-framed windows. contrast is provided by a modulated tower vertically emphasised by fins. above ground floor the facade is clad in green terracotta tiles. the building features two main entrances incorporating stairs and escalators leading to wynyard station. the interior of the building retains original office fitouts with fine timber joinery and decorative plaster ceilings. the first floor windows are notable for their individual design. awarded the sulman medal in 1935 and the riba medal in 1939, this building is an elegant example of 1930s commercial architecture. transport house forms part of a group of buildings of a similar scale. fragments of the underground railway spaces between george street and railway house, also designed by h. e. budden & mackey, survive in york street.
