The station was opened on 1 July 1879 by the District Railway (DR, now the District line) on its extension from Turnham Green to Ealing Broadway. The station was originally named Acton Green after the adjacent Acton Green Common to the east. It was renamed to Chiswick Park and Acton Green in 1887. Following the electrification of the DR's tracks north of Acton Town in 1903, services between Acton Town and central London were electrified on 1 July 1905. In 1910 the station was given its present name. Between 1931 and 1932 the station was rebuilt, in preparation for the western extension of the Piccadilly line from Hammersmith. Although the Piccadilly line has never served the station, its trains run non-stop through the station and the reconstruction was required to enable the addition of two fast tracks for those services to be located between the District line's stopping service tracks.
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. The station has payphones, a bridge and waiting room.
