The new station was designed by Charles Holden in a modern European style using brick, reinforced concrete and glass. Holden's design was inspired by Alfred Grenander's underground station "Krumme Lanke" in Berlin. Similar to the station at Arnos Grove that Holden designed for the eastern Piccadilly line extension, Chiswick Park station features a tall semi-circular ticket hall adjacent to the embankment carrying the tracks. Externally the brick walls of the ticket hall are punctuated with panels of clerestory windows and the structure is capped with a flat concrete slab roof which abuts the cantilevered concrete canopy of the westbound platform. A similar canopy shelters the eastbound platform accessed through the embankment. To make the station's location visible from Chiswick High Road the station was also provided with a square brick tower surmounted by the UNDERGROUND roundel and the station's name.
